Frequently asked questions about the Nomad KCST 9029AES(TD) snow blower: specifications, operation, and maintenance

Construction and main capabilities

What is the Nomad KCST 9029AES(TD), and what work is it intended for?

The Nomad KCST 9029AES(TD) is a self-propelled tracked petrol snow blower with a two-stage clearing system. It clears residential grounds, paths, paved areas, driveways, and moderately sized car parks.

The machine has a Loncin G270FD four-stroke engine developing up to 9 hp, a metal auger, rotating discharge chute, electric starter, headlight, and heated grips. The friction transmission provides five forward and two reverse speeds. The tracked undercarriage is designed for compacted snow and uneven ground.

Alternative designations include KCST9029AES(TD), KCST 9029 AES(TD), and KCST9029AES. Parts selection must account for the full version designation and actual machine construction.

What are the clearing width and snow intake height?

Working width is 74 cm, and intake height is 52 cm. By width, the machine belongs to the approximately 29-inch snow blower class.

These dimensions apply directly to the working auger housing. Overall dimensions with tracks, installed handles, and discharge chute may be considerably larger. The exact total length, width, and height of the AES(TD) version have not been established.

.

How does two-stage snow clearing operate?

The snow blower uses two successive stages. First, the steel auger gathers snow across the housing width, breaks up compacted areas, and moves it towards the central opening. Second, the metal impeller accelerates the snow and ejects it through the discharge chute.

This division of functions permits relatively large snow volumes to be processed. Performance depends on snow depth and density, selected travel speed, engine speed, and auger mechanism condition.

What materials are used for the auger, impeller, and discharge chute?

The auger is steel with raised serrated edges intended, among other tasks, to break up dense and packed snow. The second-stage impeller is also metal.

The rotating discharge chute body is steel. Discharge direction is changed by a mechanical drive operated from the operator panel.

How far does the snow blower throw snow?

The declared maximum throwing distance is up to 12 m. This is a limit rather than a constant distance on every pass.

Distance depends on snow moisture and density, engine speed, housing loading, and upper deflector position. Wet, heavy snow generally reduces distance. For more effective operation, reduce travel speed while maintaining sufficient engine speed to drive the impeller.

How much does the tracked model weigh?

The Nomad KCST 9029AES(TD) with a Loncin G270FD engine weighs 120 kg. This value applies to the tracked AES(TD) version.

Wheeled and other tracked KCST9029-family models differ in weight because of undercarriage, engine, and accessory construction.

.

Engine and fuel system

What engine is installed on the snow blower?

The Nomad KCST 9029AES(TD) uses a Loncin G270FD: an air-cooled, single-cylinder, four-stroke petrol engine with a displacement of 270 cm³ and a horizontal output shaft. Maximum snow blower output is declared as 9 hp.

The engine has a carburettor fuel system and electronic contactless ignition. Petrol and engine oil are in separate systems. Add clean petrol to the fuel tank and engine oil to the crankcase.

What cylinder dimensions and operating characteristics does the Loncin G270FD have?

Bore is 77 mm, stroke is 58 mm, and displacement is 270 cm³.

A separate standard Loncin G270FD A-type version lists:

These values describe a particular engine version. Clearing time per tank depends on actual loading and cannot be calculated precisely from specific consumption alone.

What G270FD output shaft dimensions are available?

The Loncin G270FD is produced with different output shafts. One A-type version specifies a diameter of 25 mm and length of 60 mm. Another lists 25.4 mm diameter and 88 mm length.

Before buying a replacement engine, crankshaft, or drive pulley, measure the shaft actually installed. Also check keyway position, mounting holes, and mating belt drive components.

.

What are the Loncin G270FD engine dimensions and weight?

The A-type version lists approximate dimensions of 430 × 380 × 410 mm and an unpackaged weight of 28.8 kg. Another G270FD configuration measures approximately 500 × 380 × 420 mm and weighs about 28 kg.

These describe the engine as a separate product, not the complete snow blower dimensions or weight.

What petrol is used, and must oil be added to it?

The four-stroke engine requires clean, fresh, unleaded petrol. No oil is added to the fuel: engine lubrication comes from a separate crankcase.

The related KCST9029ES(TD) family recommends petrol stored for no more than three months. Prolonged fuel storage may cause carburettor deposits, impaired fuel delivery, and difficult starting.

What is the Nomad KCST 9029AES(TD) fuel tank capacity?

Two values are listed for this version: 3.8 L and 1.5 L. The 3.8 L value is specified for the tracked AES(TD), but another specification for the same model lists 1.5 L. The discrepancy has not been explained.

Refuel according to the actual tank and permissible level of the particular unit. A 6 L tank is also listed for the standalone Loncin G270FD A-type, but this belongs to another engine configuration and does not establish snow blower tank capacity.

How should the fuel tank be filled?

  1. Stop the engine and allow it to cool.
  2. Position the snow blower on a level outdoor surface.
  3. Remove snow and dirt around the petrol tank cap.
  4. Add fresh petrol through a clean funnel or container spout.
  5. Leave approximately 1.5 cm of space at the top for fuel thermal expansion.
  6. Close the cap and remove spilled petrol before starting.

Some filler necks contain a mesh filter. Inspect and clean it of dirt, rust, and foreign material obstructing fuel flow.

.

What electrical equipment variants are found on the Loncin G270FD?

Engine electrical equipment depends on the version. One Loncin G270FD A-type has a 5 A lighting coil and rectifier-regulator producing 12 V DC. The permissible electrical load is 60 W.

Another G270FD version has a 12 V DC electric starter, a 2 A generating coil, and an oil level sensor. Some battery-equipped family configurations specify a 12 V battery with a rated charge capacity of 18 A·h.

The AES(TD) headlight and heated grips are confirmed, but its generating coil type, supply arrangement, and battery presence have not been established.

What cooling and governor characteristics should be considered?

The Loncin G270FD is air-cooled. Maintain normal temperatures by cleaning external cooling surfaces and checking ventilation passages and protective covers.

The centrifugal governor automatically adjusts throttle position according to load. Retain the factory maximum speed limit: excessive speed imposes dangerous loading on the engine, belts, and auger drive.

Assembly and preparation

The following handle, linkage, and chute assembly operations are described in detail for the related KCST9029ES(TD) tracked model. Mounting locations and individual components may differ on the AES(TD), so compare the particular machine before assembly.

How is the main control handle installed?

Raise the main handle to its working position and secure it with the standard bolts and nuts. After final tightening, check joint rigidity, alignment, and free control lever movement.

Route cables without sharp bends or trapping beneath fasteners. When moving the handle and engaging levers, ensure that cables and rods do not catch on fixed enclosure parts.

.

How is the gear shift rod installed and adjusted?

On the KCST9029ES(TD), the rod connects the travel speed and direction selector to the shift mechanism in the lower rear, below the manual starter housing.

  1. Place the shift lever and connecting rod in their working positions.
  2. Secure the upper rod end with a split pin.
  3. Secure the lower end with a nut at the designated shift mechanism connection.
  4. Adjust rod length so that each selector position corresponds to the transmission mechanism position.
  5. Check lever movement throughout all forward and reverse speeds.

Incorrect rod length may cause incomplete gear engagement or impaired self-propelled drive operation.

How is the discharge chute installed?

Mount the discharge chute on the annular support flange of the auger housing.

  1. Clean dirt and foreign particles from the annular base.
  2. Apply waterproof grease to the contact surface.
  3. Place the discharge chute on the flange.
  4. Secure it with curved retaining plates and bolts.
  5. Check that the retainers hold the chute on the base while allowing free rotation.

After installation, the chute should move smoothly within its designed range.

How is the chute rotation mechanism connected?

On the KCST9029ES(TD), the control rod connects to the rotation mechanism through a joint secured by a split pin. During assembly, install the connection, lubricate it with waterproof grease, and check secure retention.

After installation, turn the control handle both ways, monitoring chute movement, gear engagement, and absence of binding.

.

What should be checked before initial starting and at the start of the season?

During a test run, mechanisms should operate without strong jerks, abnormal impacts, or noticeable drive slip.

Starting and stopping the engine

What should be checked immediately before starting a cold engine?

Position the snow blower on a flat, level surface. Check engine oil level, fresh petrol availability, and secure spark plug lead connection.

Both clutch levers, for the auger and traction drives, must be released.

On the described KCST9029ES(TD), move the engine speed control to maximum and insert the ignition key until retained. The key acts as a safety insert and is not turned during starting.

If a low oil sensor is fitted, the engine may fail to start or stop when crankcase oil is insufficient.

.

How are the choke and primer used?

The carburettor choke and fuel primer are used for cold engine starting.

On the described KCST9029ES(TD), the grey choke lever is behind the engine. Turn it clockwise to close the choke. The primer is a red rubber button.

Excessive warm-engine priming can over-enrich the mixture and wet the spark plug with petrol.

How is the engine started with the manual recoil starter?

  1. Check oil level, petrol, key position, and disengagement of both drives.
  2. For a cold engine, close the choke and operate the primer.
  3. Hold the starter handle and pull slowly until noticeable resistance is felt.
  4. Allow the cord to return smoothly while holding the handle.
  5. Pull rapidly and firmly to start the engine.
  6. Hold the handle during return, guiding the cord into the housing without an abrupt impact.
  7. After starting, open the choke gradually.

If opening the choke causes stalling, temporarily close it further, then open gradually again. Allow several minutes of warm-up before engaging the auger.

What electric starter is installed on the Nomad KCST 9029AES(TD)?

Electric starting on the AES(TD) is confirmed, but starter voltage and supply arrangement have not been established.

The related KCST9029ES(TD) provides a 230 V, 50 Hz mains starter; some descriptions of this family specify 220 V. Loncin G270FD configurations with a 12 V DC starter also exist.

Before connection, check the installed starter marking, mains connector presence, and starter supply type. Apply mains voltage only to a starter rated for it.

How is the KCST9029ES(TD) started with a 230 V mains starter?

This sequence applies to the KCST9029ES(TD) version equipped with a 230 V, 50 Hz AC starter.

  1. Ensure that both clutch levers are released and the engine is prepared.
  2. Use a serviceable three-conductor extension lead with protective earthing.
  3. Connect the extension to the engine electrical socket first.
  4. Then connect its plug to an earthed mains socket.
  5. For a cold engine, close the choke and press the primer two or three times.
  6. Press the electric starter button and release it immediately after starting.
  7. Open the choke gradually as the engine warms.
  8. After starting, disconnect the extension from the mains socket first, then from the engine.
  9. Remove the cable from the travel area and possible auger intake zone.

If the engine begins to stall as the choke opens, temporarily return it to a more closed position and repeat gradual opening.

How long may the electric starter operate continuously?

One starting attempt with the described KCST9029ES(TD) mains starter is limited to approximately seven seconds. Allow the starter to cool between attempts.

Holding the button for a prolonged period when the engine does not start overheats the starter and may damage it. For the AES(TD), follow the limits of the device actually installed.

What engine speed should be used during snow clearing?

The impeller requires sufficiently high speed for normal discharge. Use the manufacturer-specified engine operating range under load.

The centrifugal governor responds automatically to load changes. Increasing the factory maximum speed limit is not an acceptable performance adjustment.

.

How should the engine be stopped after clearing?

  1. Release the traction drive lever.
  2. Release the auger engagement lever.
  3. Wait for working mechanisms to stop rotating.
  4. Move engine speed control to STOP if the design provides this position.
  5. Remove the ignition key.
  6. After shutdown, close the fuel cock if fitted.

Then remove snow from the engine, control panel, cables, handles, and discharge chute. Pay particular attention to places where meltwater may freeze before the next start.

Controls and snow clearing

How many speeds does the snow blower have, and how are they selected?

The Nomad KCST 9029AES(TD) transmission has five forward and two reverse speeds. A mechanical lever selects them; continuously variable adjustment is not provided.

The related KCST9029ES(TD) selector has R2, R1, 1, 2, 3, 4, and 5. Forward speed 1 is slowest and 5 fastest. Reverse R1 is slower than R2.

Use low speeds for deep, dense snow and higher speeds for lighter snow with sufficient clear space.

What do the left and right control levers operate?

In the described KCST9029ES(TD) arrangement, the left lever engages the auger and the right engages traction.

Separate controls permit travel with the auger stopped. Check lever functions on the particular AES(TD) from their markings and positions.

.

How are travel and snow clearing started?

  1. Start the engine and allow it to warm up.
  2. With the traction lever released, select a suitable gear.
  3. Set discharge direction and upper deflector position.
  4. Hold the auger lever to start gathering and ejecting snow.
  5. Hold the travel lever and begin a pass over the area.
  6. Release the traction lever to stop moving.
  7. Release the auger lever to stop gathering and discharge.

This sequence corresponds to the KCST9029ES(TD) layout. On the AES(TD), account for actual control locations and functions.

Can gears be changed while moving?

For the KCST9029ES(TD) friction transmission, change gears after releasing the traction lever and bringing the machine to a complete stop.

Changing direction or speed with the drive engaged increases wear of the friction ring and selector components. Stop completely, select the new gear, and re-engage travel.

How should a gear be selected for wet, dense, or deep snow?

Use a low forward gear for heavy snow. Slower travel reduces snow intake to the auger and impeller per unit time.

If engine speed falls noticeably, reduce travel speed. As snow depth decreases, a higher gear can be selected after stopping traction.

Use the provided reverse speeds for manoeuvring in confined areas.

.

How is the discharge chute turned right or left?

A mechanical drive from the operator panel changes discharge direction. On the KCST9029ES(TD), turning the control handle clockwise turns the chute right; anticlockwise turns it left.

The operator does not need to walk around the machine and turn the metal chute manually to redirect snow.

If movement is difficult, check for ice on the rotating base, free linkage movement, and correct gear engagement.

How are discharge height and distance adjusted?

The upper deflector angle determines discharge trajectory. Changing it directs the stream higher or lower and also affects throwing distance.

For manual deflector adjustment, stop the engine, wait for auger and impeller stoppage, and prevent accidental starting.

Even at the highest deflector position, actual distance depends on snow condition and impeller performance.

How do heated grips operate?

The Nomad KCST 9029AES(TD) has heated operator grips for sub-zero operation, particularly when controls must be held for prolonged periods.

The exact switch position, separate temperature modes, and electrical consumption of the AES(TD) have not been established. Determine operation from the actual panel and handle switches.

What is the headlight for?

The headlight illuminates the area ahead when natural light is insufficient. It is included on the AES(TD).

Its lamp type, rated voltage, power, and activation method are unconfirmed. Identify the installed equipment characteristics before replacement.

.

What is the body tilt pedal for?

The related tracked KCST9029ES(TD) has a foot pedal to change machine tilt relative to the surface. It forms part of the body and auger housing position adjustment mechanism.

For the AES(TD), the number of fixed positions, latch locations, and relationship between positions and clearing conditions have not been established. Inspect the adjustment device directly on the undercarriage.

How is housing height adjusted for asphalt, paving, or gravel?

On KCST9029ES(TD)-family snow blowers, side skid shoes adjust lower scraper height.

On level hard surfaces, raise the shoes relative to the housing so that the scraper runs closer to the ground. On gravel or loose stone, lower the shoes to increase clearance and reduce stone intake risk.

To adjust:

  1. Position the machine on a level surface and stop the engine.
  2. Loosen the four skid shoe hex nuts, two on each housing side.
  3. Set both shoes symmetrically to the required height.
  4. Ensure that their bearing surfaces are equally positioned relative to the ground.
  5. Tighten the nuts and bolts securely.

Unequal shoe heights may cause uneven scraper wear and make the snow blower pull to one side.

How are worn skid shoes and the lower scraper replaced?

Skid shoes and the lower scraper are wear components. Inspect for abrasion, cracks, deformation, and damaged mounting holes.

To replace KCST9029ES(TD) side shoes, remove four mounting bolts and nuts, remove the old shoes, and install new ones in reverse order. Then adjust height symmetrically.

Replace the lower scraper after removing fasteners along the lower housing edge. Install the new part in its original position and tighten bolts securely.

.

Tracked undercarriage and transmission

How does the tracked undercarriage differ from a wheeled one?

The Nomad KCST 9029AES(TD) has triangular track assemblies, providing a relatively large contact area for compacted snow and uneven terrain.

The undercarriage supports stable travel of the heavy self-propelled machine. Normal operation requires monitoring rubber track belts, guides, rollers, and tensioning mechanisms.

How are turns made, and is track release provided?

A track locking system is mentioned for the AES(TD) to improve manoeuvrability. Another specification describes a differential lock controlled on the undercarriage.

The exact individual track release lever design and turning procedure have not been established for the AES(TD). Before adjustment or repair, identify the locking mechanism actually installed.

How is track tension checked and adjusted?

On the related KCST9029ES(TD), side undercarriage mountings and tensioning bolts adjust each track.

  1. Stop the engine and position the machine on a stable surface.
  2. Inspect both tracks and their positions on rollers and guides.
  3. Loosen the corresponding side tensioner fasteners.
  4. Adjust track position and tension with the tensioning bolts.
  5. Check even belt seating and drive component positions.
  6. Tighten fasteners and repeat on the other side.

Numerical sag and tension force specifications have not been established for the AES(TD). Determine them according to the actual undercarriage design.

.

What should be done if a track leaves its rollers or guides?

Stop the engine and prevent accidental starting before repositioning a track.

  1. Inspect the belt and remove snow, ice, and foreign objects from the undercarriage.
  2. Loosen side mountings and the affected track tensioner.
  3. Create sufficient slack for installation.
  4. Return the track to its guides, rollers, and drive components.
  5. Ensure correct seating along the entire length without skewing.
  6. Restore tension and tighten adjustment fasteners.

After installation, check free component movement and ensure that the belt is not trapped between rollers and the housing.

Why does the tracked snow blower jerk or pull to one side?

Possible causes include unequal track tension, frozen snow between belt and rollers, damaged guides, or a faulty locking mechanism.

Check in sequence:

A foreign object between track belt and roller can cause jerking and repeated derailment.

How is the friction transmission arranged?

Travel is transmitted through a friction mechanism. Its main working components are a metal drive disc and a rubber-ringed friction wheel pressed against it when the drive engages.

Friction wheel position relative to the drive disc corresponds to the selected gear. Operation depends on rubber surface condition, correct cable adjustment, a serviceable belt, and oil-free contact surfaces.

.

Why does the engine run while the snow blower does not move or moves slowly?

Several causes are possible in a friction traction drive:

If movement is weak under load, first check cable tension and the friction assembly. Prolonged slipping accelerates rubber ring wear.

How is the traction engagement cable adjusted?

On the KCST9029ES(TD), the traction cable connects to the right lever and has an adjustable threaded connection.

  1. Stop the engine and check control lever free play.
  2. Locate the cable threaded adjustment section.
  3. Increase tension gradually by reducing free cable length.
  4. Check drive engagement after each small change.
  5. With the lever held, the machine should move positively in the selected gear.
  6. With the lever released, traction must disengage completely.

If cable adjustment does not eliminate slip, check the friction ring, belt, and correspondence between selector and shift mechanism positions.

What friction ring size is used on the Nomad KCST 9029AES(TD)?

During repair of a particular Nomad KCST 9029 AES(TD) on 11 May 2023, a rubber friction ring with an internal diameter of 110 mm was installed.

This is a practical reference for the tracked AES(TD). Before purchase, also measure external diameter, thickness, ring profile, and the design of the metal friction wheel halves.

Replacement of the rubber ring alone, without mandatory replacement of the complete friction wheel, has been confirmed on the AES(TD).

What friction wheel damage requires rubber replacement?

Inspect for cracks, working-edge wear, ring misalignment, overheating marks, and characteristic slipping damage.

If the rubber is substantially worn or destroyed, cable adjustment will not restore normal contact with the drive disc. Replace the damaged ring or complete friction wheel.

Also check the metal disc so that the new rubber runs against a smooth, clean surface.

How is the friction wheel rubber ring replaced on wheeled KCST9029ES versions?

The following procedure is described for the wheeled KCST9029ES. Shaft access differs on the tracked AES(TD), so undercarriage disassembly must not be transferred automatically.

  1. Set the selector to third forward gear F3.
  2. Drain fuel and tilt the snow blower forward onto its auger housing.
  3. Remove the lower housing cover secured by four screws.
  4. Remove the right wheel and hub fastener.
  5. Unscrew the hex nut and remove the hex shaft support washer.
  6. Carefully release the bearing from the right frame side and lower the shaft.
  7. Slide the friction wheel along the shaft and remove it.
  8. To replace only the rubber ring, remove the four screws joining the two metal side plates.
  9. Remove the worn ring and place a new one between the plates.
  10. Tighten the four screws gradually, approximately one turn each, then rotate the wheel and proceed to the next screw. Repeat until the rubber is evenly clamped.

Before disassembling the tracked AES(TD), determine shaft support positions and friction assembly access according to undercarriage construction.

.

How are the hex shaft and transmission chains lubricated?

The KCST9029ES(TD) specifies servicing the friction wheel sliding hex shaft and chain drives at least once per season or approximately every 25 operating hours.

  1. Stop the engine, wait for all mechanisms to stop, and disconnect the plug lead.
  2. Remove the lower transmission cover secured by four screws.
  3. Clean dirt and old grease from the hex shaft.
  4. Apply a thin layer of all-weather multipurpose grease to designated surfaces.
  5. Service the chain drive and check its condition.
  6. Refit the lower cover and restore fasteners.

Keep the rubber friction wheel and aluminium drive disc working surfaces clean and dry. Oil and grease reduce friction and cause slip.

What is the grease nipple on the housing side for?

A grease nipple is described on the left side of the KCST9029ES(TD) housing. Service it during assembly and then once or twice per season according to usage.

Four or five grease gun strokes are specified per service. On some versions with a body tilt pedal, the nipple is installed only for lubrication so that it does not obstruct pedal movement.

Determine nipple presence and position on the AES(TD) by inspecting the particular unit.

Auger mechanism, gearbox, and belt drives

What are auger shear pins for?

Shear pins protect the connection between auger sections and the drive shaft. If a stone, metal object, board, or large ice piece is ingested, excessive load breaks the pin and disconnects that section from the shaft.

This reduces the risk of gearbox and drive damage. The related KCST9029ES(TD) describes two pins securing the auger sections.

If the impeller continues rotating but one auger half stops feeding snow, check its shear element.

.

How is a broken shear pin replaced?

  1. Stop the engine and wait for complete auger and impeller stoppage.
  2. Remove the ignition key and spark plug lead cap.
  3. Remove broken pin remains.
  4. Clear the trapped object and ensure that the section moves freely relative to the shaft.
  5. Align the auger section hub and drive shaft holes.
  6. If necessary, apply a small amount of grease to the joint.
  7. Install and secure a new standard shear pin of the specified strength.

Use special shear elements designed to break under overload. An ordinary bolt, nail, or steel stud may not shear during a jam and may damage the gearbox.

How can the auger be prevented from seizing onto its drive shaft?

On the KCST9029ES(TD), check free auger section rotation relative to the shaft at least once per season.

  1. Stop the engine and disconnect the plug lead.
  2. Remove the auger section shear pins.
  3. Check that both sections rotate freely relative to the shaft.
  4. Remove dirt and corrosion.
  5. Lubricate the shaft surface and spacer bushing areas.
  6. Refit the standard shear pins.

If the auger rusts onto the shaft, shear pin protection may become ineffective because overload is transmitted directly to drive components.

What auger shaft supports require lubrication?

The related KCST9029ES(TD) specifies lubrication of flange supports at both auger shaft ends.

During servicing, check free rotation, fastener condition, and absence of rust or damaged support connections. Lubrication is recommended before and after the season.

.

How is the auger gearbox arranged, and what is its housing material?

The Nomad KCST 9029AES(TD) specifies an aluminium auger gearbox housing. Its internal gears transmit rotation to the auger shaft.

An aluminium housing does not mean that internal gears are aluminium. Exact worm and driven wheel materials, ratio, and seal design have not been established for the AES(TD).

What grease and quantity are used in the auger gearbox?

The related KCST9029ES(TD) family uses a closed, factory grease-filled gearbox. After disassembly, approximately 57 g of fresh grease is specified. This quantity applies to the described family and is not separately confirmed for the AES(TD).

A Nomad KCST 9029 AES(TD) repair used Mannol Li-EP-2 9985 lithium-calcium worm gearbox grease. The listed package was a 100 mL syringe. This is package capacity rather than a specified gearbox filling quantity.

Servicing must account for housing and seal construction. Excess grease may damage seals and leak. If a vent or relief plug is provided, check that it is clear.

How is the auger drive belt replaced?

The KCST9029ES(TD) specifies this removal sequence:

  1. Stop the engine, wait for components to stop, and prevent accidental starting.
  2. Drain petrol or prevent leakage when the machine is tilted.
  3. Remove the front belt guard by unscrewing two self-tapping screws.
  4. Tilt the machine forward to rest stably on its auger housing.
  5. Remove the lower transmission cover secured by four screws.
  6. Release the auger belt from the engine pulley.
  7. Disconnect the belt restraint and support bracket spring.
  8. Remove the old belt from between the bracket and pulleys.
  9. Install the new belt in reverse order.
  10. Return the restraint bolt, bracket spring, and protective covers to their standard positions.

After assembly, check auger operation and complete disengagement when the control lever is released. The exact AES(TD) belt size is unestablished, so select it from the actual assembly.

.

How is the traction drive belt replaced?

On the KCST9029ES(TD), the traction belt transfers engine power to the friction transmission.

  1. Stop the engine, disconnect the plug lead, and prevent fuel leakage during tilting.
  2. Remove the front belt guard and lower housing cover.
  3. Move the tensioning idler right.
  4. Remove the auger belt from the engine pulley for access.
  5. Release the traction belt from its pulley.
  6. Remove the old belt from between the friction wheel and metal drive disc.
  7. Route the new belt in reverse order.
  8. Restore tensioner and auger belt positions.
  9. Refit guards and check correct traction engagement and complete disengagement.

On the tracked AES(TD), check component access and fastener locations before replacement.

When are belt adjustment and fastener checks required?

Check belt tension when traction weakens, auger performance deteriorates, slip appears, and after belt drive disassembly.

Nomad KCST 9029 AES(TD) servicing on 11 May 2023 included bolt retightening and belt tension adjustment. These are practical servicing tasks alongside cable and friction mechanism checks.

After adjustment, ensure engagement without pronounced slip and complete disengagement when the corresponding lever is released.

.

How is the chute rotation gear mechanism adjusted?

If the KCST9029ES(TD) drive pinion does not mesh correctly with the chute ring gear, adjust its bracket position.

  1. Stop the engine and prevent accidental auger engagement.
  2. Inspect the pinion, ring gear, and control mechanism mounting.
  3. Loosen the pinion bracket bolts.
  4. Move the bracket until the teeth align correctly.
  5. Tighten the bolts and check rotation throughout the available range.
  6. Repeat adjustment if necessary.

If binding occurs, also check for ice, corrosion, and support flange grease condition.

What lubricant is used for the chute rotation mechanism?

Use waterproof grease on the annular flange and moving rotation drive parts. Service the ring contact surface, control rod joint, and accessible moving components.

KCST9029ES(TD) family recommendations also mention petroleum jelly, mineral oil, and light multipurpose lubricants for some external joints and rods.

Regular cleaning and lubrication prevent binding caused by corrosion, dirt, and frozen meltwater.

How is a snow-blocked discharge chute cleared safely?

  1. Release both control levers.
  2. Stop the engine and remove the ignition key.
  3. Wait for complete auger and impeller stoppage. The impeller may coast after disengagement.
  4. Use the dedicated cleaning shovel or handled scraper.
  5. Break up and remove the blockage with the tool, keeping hands away from the discharge opening and working components.
  6. Ensure no hard foreign objects remain in the housing or discharge passage.
  7. Return the tool to its designated holder.

On the KCST9029ES(TD), a clip retains the cleaning shovel on the auger housing. Check its presence and mounting location on the particular AES(TD).

.

Engine maintenance

What engine oil is suitable for winter use?

SAE 5W-30 winter oil is recommended for KCST9029ES(TD)-family engines. Below -18 °C, SAE 0W-30 is specified. Quality must be API SF, SG, SH, or a compatible newer category.

The family recommendations specifically state that SAE 10W-40 should not be used in winter conditions.

Servicing of a particular Nomad KCST 9029 AES(TD) used PRIMETECH SAE 5W-30 four-stroke engine oil. The listed package held 0.95 L; the actual quantity added was unspecified.

How much oil is required for the Loncin G270FD?

A separate standard Loncin G270FD version has approximately 0.95 L crankcase capacity. The general KCST9029ES(TD) family also lists approximately 1.1 L depending on the engine installed.

For AES(TD) servicing, follow the actual Loncin G270FD version and dipstick level. Add oil gradually, monitoring HIGH or FULL and avoiding overfilling.

How is engine oil level checked correctly?

On the KCST9029ES(TD), check before every use and additionally every five operating hours.

  1. Position the snow blower on a level surface.
  2. Stop the engine and allow oil to drain into the crankcase.
  3. Clean around the oil filler.
  4. Remove the dipstick and wipe with a clean cloth.
  5. Check level using the method specified for the installed engine.
  6. If low, add suitable oil to the required mark.

The KCST9029ES(TD) family manual describes fully screwing in the dipstick before measurement. Some standalone Loncin G270FD configurations specify inserting it without screwing in. The correct method depends on filler construction and installed engine documentation.

.

After how many hours should engine oil be changed?

The KCST9029ES(TD) specifies the first change after two hours on a new engine, followed by changes every 25 running hours.

Another schedule for related GardenPro snow blowers specifies the first change after five hours, then every 50 hours and preferably at least once per season.

No single confirmed interval is established specifically for the Nomad KCST9029AES(TD) with Loncin G270FD. Base scheduling on installed engine documentation, version, and operating conditions.

How is engine oil changed?

  1. Warm the engine briefly to reduce oil viscosity.
  2. Stop it and allow slight cooling to reduce burn risk.
  3. Check that the fuel tank cap is tightly closed.
  4. Clean around the crankcase drain plug.
  5. Place a suitable used oil container below.
  6. Unscrew the plug and drain old oil completely.
  7. Refit and tighten the drain plug securely.
  8. Add fresh oil of suitable viscosity in small portions.
  9. Check with the dipstick using the engine-specified method.
  10. After servicing, ensure no leakage around the drain plug.

Determine quantity from actual level, accounting for the approximate crankcase capacity of the installed engine.

When should the spark plug be inspected and replaced?

Related KCST9029ES(TD)-family engines specify annual inspection or every 100 running hours.

Clean around the plug opening before removal. Then inspect the porcelain insulator, electrodes, and carbon deposits.

Replace a plug with a cracked insulator, severe burning, deformed electrodes, or other substantial damage.

What spark plug electrode gap is required?

The described KCST9029ES(TD) engines specify 0.76 mm. Some Loncin G270FD technical data list approximately 0.7-0.8 mm.

Check with a dedicated feeler gauge and adjust, if necessary, within the limits for the particular plug and engine.

What spark plugs are found on engines in this family?

The related family specifies F7RTC and possible equivalents Denso W20EPR, Champion RN9YC, and Bosch W7DTC.

Before installation, check thread, threaded length, heat range, resistor presence, and requirements of the exact Loncin G270FD version. Do not assume automatic interchangeability across all AES(TD) versions.

How are the Loncin G270FD valve clearances checked and adjusted?

Perform the check with the engine completely cold. One set of service data for the corresponding Loncin engines specifies the following clearances: intake valve 0.15 ± 0.02 mm, exhaust valve 0.20 ± 0.02 mm.

Other documentation for the engine family specifies ranges of 0.10-0.15 mm for the intake valve and 0.15-0.20 mm for the exhaust valve. Confirm the required value for the exact G270FD version.

  1. Stop the engine and allow it to cool completely.
  2. Provide access to the valve mechanism.
  3. Set the piston at top dead centre on the compression stroke, with both valves closed.
  4. Insert a feeler gauge of the required thickness between the rocker arm and the valve stem tip.
  5. Adjust the clearance to the value specified for the engine.
  6. Secure the adjustment components and check the clearance again.
.

How is the air filter serviced?

Some Loncin G270FD versions have a replaceable air filter with paper and foam elements.

The general maintenance schedule for the Loncin engine family specifies filter cleaning every 50 hours and element replacement every 100 hours or six months.

Engines specifically prepared for winter operation may have a different air intake design. Before servicing the AES(TD), check whether a filter is actually fitted and identify the type of installed element.

How is the fuel valve sediment bowl cleaned?

If the engine has a fuel valve with a sediment bowl, this component can be serviced separately.

  1. Stop the engine and allow it to cool.
  2. Close the fuel valve.
  3. Carefully remove the sediment bowl and its sealing ring.
  4. Remove dirt and fuel deposits.
  5. Refit the seal and bowl in their designated positions.
  6. Open the valve and check for petrol leaks.

What is the purpose of the low oil level sensor?

Some Loncin G270FD configurations have a sensor that switches off the ignition when the crankcase oil level is insufficient.

If the engine stops suddenly or there is no spark during a starting attempt, measuring the oil level is one of the first checks. Whether a particular AES(TD) unit has this sensor depends on the engine configuration.

Faults and remedies

What should be checked if the engine will not start after prolonged storage?

Begin diagnosis with the fuel, oil, and starting controls.

  1. Check that there is fresh petrol in the tank.
  2. Ensure that the fuel valve is open, if fitted.
  3. Check that the ignition key is correctly installed.
  4. Measure the crankcase oil level.
  5. Check that the high voltage lead is securely connected to the spark plug.
  6. Set the choke to the position appropriate for the engine temperature.
  7. For a cold start, operate the primer as required.
  8. If the engine still will not start, inspect the spark plug and check fuel delivery through the carburettor.
.

What does a wet spark plug or black carbon on the electrodes indicate?

A spark plug wet with petrol may indicate an excessively rich mixture, including after excessive use of the primer. Heavy black carbon deposits are characteristic of incomplete fuel combustion and may be associated with incorrect fuel system operation.

Remove, inspect, clean, and dry the spark plug. Then check the electrode gap and the presence of a spark. Replace a damaged or severely worn plug with one of suitable specifications.

If carbon deposits recur, check the choke position, fuel condition, and carburettor operation.

What should be done if petrol does not reach the engine?

After prolonged inactivity, the fuel strainer may become dirty, deposits may form in the carburettor, and individual fuel delivery components may become blocked.

Check the tank strainer, fuel valve, petrol supply hose, and carburettor float chamber in sequence. Clean the sediment bowl if fitted.

If deposits are found inside the carburettor, disassemble and clean the assembly while maintaining the manufacturer's specified settings.

Why has the auger stopped collecting snow although the engine is running?

First determine whether the impeller is rotating and both auger sections are operating. If the impeller rotates but one half of the auger remains stationary, the corresponding shear pin is probably damaged.

If all parts of the auger mechanism have stopped rotating, check the belt, drive tension, control cable, and possible jamming.

Before inspection, stop the engine, wait until all mechanisms have stopped completely, and disconnect the spark plug lead.

.

Why is the discharge chute difficult to rotate?

Possible causes include ice on the support ring, a dirty rotating flange, corrosion, insufficient lubrication, or incorrect drive pinion engagement.

After stopping the engine, clean the circular base and inspect the joints and gear mechanism. Lubricate the contact surfaces with water resistant grease.

If the gear engagement is incorrect, adjust the drive pinion bracket, then check chute rotation throughout its available range.

Why does the engine stop under load or lose speed?

An excessive intake of dense snow can cause a noticeable reduction in engine speed. In this case, reduce the forward speed to decrease the volume of material entering the impeller.

If the engine repeatedly stops even without a substantial snow load, check fuel freshness and delivery, choke position, spark plug condition, and oil level.

On Loncin G270FD configurations with an oil sensor, an excessively low level can cause the ignition to switch off.

Why does the traction drive slip under load?

The main causes are insufficient traction engagement cable tension, a worn friction ring, a contaminated drive disc, or a faulty belt.

First check the cable adjustment and ensure that there is no oil on the friction assembly contact surfaces. Then inspect the rubber ring and belt drive.

Also check the selector linkage position. Incorrect correspondence between the lever and the shifting mechanism can impair drive transmission.

Storage and safety

How should the snow blower be cleaned after use?

After stopping the engine, remove residual snow from the auger housing, auger, discharge chute, control panel, cables, handles, and external engine surfaces.

Clean the circular chute base and its gear drive particularly thoroughly. Snow melted by the heat of the running engine can freeze again and lock the rotation mechanism or impeller.

Also remove snow, ice, and foreign objects from the tracks and rollers.

.

How should the fuel system be prepared for prolonged storage?

For the KCST9029ES(TD), storage for 30 days or more requires petrol to be removed from the tank and carburettor.

  1. Stop the engine and allow it to cool.
  2. Outdoors, drain the bulk of the fuel into a suitable container.
  3. After draining the fuel, start the engine to consume the remaining petrol.
  4. Wait until the engine stops.
  5. Open the carburettor float chamber drain screw and remove the remaining fuel.
  6. Close the drain screw and check the fuel system for leaks.

Removing old petrol reduces the likelihood of deposits that make the next start difficult.

How should the engine cylinder be protected during seasonal storage preparation?

For prolonged storage of the related KCST9029ES(TD) family, additional protection of the internal cylinder surface with engine oil is specified.

  1. Stop the engine and disconnect the spark plug lead.
  2. Unscrew the spark plug.
  3. Introduce a small quantity of clean engine oil directly into the cylinder through the spark plug hole.
  4. Cover the hole with a cloth.
  5. Slowly turn the crankshaft several times with the recoil starter to distribute oil over the cylinder walls.
  6. Refit the spark plug.

When returning the engine to service, bear in mind that the first start after this storage preparation may produce brief smoke as residual oil burns off.

Which parts should be lubricated before seasonal storage?

After cleaning and drying the machine, service the chains, bearings, springs, joints, cable connections, and lubrication points provided by the design.

Pay particular attention to the auger shaft, its connections with the shear pins, and the discharge chute rotation mechanism. Remove dirt and road salt that promote corrosion from the external surfaces.

Keep the working contact surfaces of the friction ring and drive disc clean.

.

Under what conditions should the tracked snow blower be stored?

A dry enclosed space with a firm, stable floor is preferable for the Nomad KCST 9029AES(TD).

Before prolonged inactivity, remove dirt, stones, snow, and ice from the track belts, rollers, and guides. Snow remaining between the belt and rollers can freeze and lock the undercarriage.

Position the machine securely to prevent unintended movement and deformation of storage or support components.

What safety precautions are required during repairs and adjustment?

Before repairing the auger, adjusting belts, removing protective covers, or servicing the transmission, stop the engine, wait until all parts stop rotating, and disconnect the spark plug high voltage lead.

Before tilting the machine, take measures to prevent petrol from escaping. When working near the engine, remember that the muffler, cylinder, and surrounding metal parts may remain very hot after operation.

Use a dedicated tool to remove snow from the discharge passage. Even after the drive is disengaged, the impeller can continue rotating through inertia for some time.

Can a petrol snow blower be started in a garage?

A petrol snow blower is intended for outdoor operation. Fuel combustion produces carbon monoxide, which is life threatening.

Starting and operating the engine in a garage, shed, or other enclosed space with insufficient ventilation creates a risk of poisoning even with the doors open.

Where can discharged snow be directed safely?

Select the discharge chute direction with due regard to the surroundings. Ice, stones, and other hard objects may be discharged together with the snow.

Direct the snow stream towards an unoccupied area, preventing it from reaching people, animals, vehicles, windows, glass structures, and equipment sensitive to impact.

Modifications and spare parts selection

How does the Nomad KCST9029AES(TD) differ from the KCST9029AES(D)?

The KCST9029AES(TD) is a tracked modification weighing 120 kg. The KCST9029AES(D) is a separate wheeled version.

The following specifications are reported for the KCST9029AES(D):

Wheel hubs, tyres, tyre pressures, and the corresponding fasteners do not apply to the tracked AES(TD) modification.

What tyre pressure is specified for the wheeled KCST9029ES(D) models?

For wheeled versions of the KCST9029ES(D) family, a pressure of approximately 15-20 psi, or 1.0-1.4 bar of pressure, is reported.

A pressure difference between the right and left wheels can cause the machine to pull to one side. These values apply only to pneumatic tyres and are not applicable to the AES(TD) rubber tracks.

How does the KCST9029ES(TD) differ from the KCST9029AES(TD)?

The KCST9029ES(TD) is a separate tracked model from a related family. One version is specified with a Briggs & Stratton Snow Series OHV 1150 engine with a displacement of 250 cm³ and a power output of 8.5 hp.

The following specifications are given for this configuration:

Other ES(TD) descriptions mention a Loncin engine. Maintenance must therefore take account of the actual configuration of the particular unit.

.

What additional specifications are reported for the KCST9029ES(TD)?

Another KCST9029ES(TD) version is specified with a weight of 127 kg, a working width of 29 inches, a maximum power output of 9 hp or 5.8 kW, and a vibration level of 3.80 m/s².

These figures apply to the ES(TD) model. They do not replace the Nomad KCST9029AES(TD) specifications, for which a weight of 120 kg, an intake height of 52 cm, and a Loncin G270FD engine are confirmed.

Can diagrams for other NOMAD models be used when repairing the AES(TD)?

Separate diagrams of the auger assembly, belt drive, transmission, friction mechanism, undercarriage, and controls are provided for the NOMAD KCST9029ES(T), KCST1129ES(T), and KCST1329ES(T) models.

The diagrams show drive shafts, chains, springs, pulleys, guides, bearings, fasteners, and chute clearing system components.

These diagrams can be used to study the operating principles of related assemblies. When repairing the AES(TD), compare the actual dimensions, mounting locations, and version of each part.

What should be considered when selecting belts, shear pins, and other spare parts?

The designations KCST9029AES(TD), KCST9029AES(D), KCST9029ES(TD), KCST9029ES(T), and KCST9029ES(D) occur within the family. Additional letter designations correspond to different machine versions.

Before purchasing, check the dimensions of belts, shear pins, track belts, rollers, hubs, bearings, friction wheels, and other connecting parts.

A matching auger housing working width or external machine appearance does not guarantee parts interchangeability. Particular attention must be paid to the undercarriage type, engine output shaft dimensions, and starter design.

For the AES(TD), a replacement friction ring inner diameter of 110 mm has been confirmed in practice. The exact dimensions of belts, shear pins, and track belts have not been established.
