4.2 SERVICE POSITIONS Ariens Dealers will provide any service or adjustments which may be required to keep your unit operating at peak efficiency. Should engine service be required, contact an Ariens dealer or an authorized engine manufacturer’s service center. 4 5 WARNING: ACCIDENTAL ENGINE START UP can cause death or serious injury. ALWAYS stop engine, remove key, wait for moving parts to stop and remove wire from spark plug before adjusting or servicing.
To add fuel to the fuel tank: 1. Refuel the unit only in a well ventilated, open area. IMPORTANT: DO NOT allow grease or oil to get on friction wheel, drive disc or belts. Apply Sten Mix Hi-Temp Grease or equivalent to the lube fittings. Order P/N: 00036800 - three pack of 3 oz. cartridges or P/N 00036800 - ten pack of 14 oz. cartridges. 2. Stop the engine and allow to cool. 3. Clean the fuel cap and the area around the fuel cap to prevent dirt from entering the fuel tank.
4.6 AUGER GEARCASE Engine Oil Check IMPORTANT: Too much lubricant may cause excessive leakage. Too little lubricant will cause gear and/or bearing damage. Proper oil level must be maintained for operation. The engine crankcase oil should be checked daily or every 5 hours of operation. Oil level MUST be maintained in safe operating range on dipstick at all times or engine damage will result (See Engine Manual). Gear cases are filled to the correct level at the factory.
4.8 ATTACHMENT DRIVE BELT WARNING: IMPROPER ADJUSTMENT could result in death or serious injury. IMPELLER BRAKE MUST DISENGAGE when clutch is engaged. Brake must be at least 1/16" (1.6 mm) to 1/8" (3.2 mm) minimum from belt when disengaged. BELT FINGERS MUST BE between 1/16 to 1/8" from belt with attachment clutch engaged or belt grabbing may occur causing impeller to rotate while attachment clutch is disengaged. 2 3 6 4 1 5 WARNING: ROTATING PARTS can cut or amputate body parts.
To Replace the Traction Drive Belt 1. Place unit in the Belt Service Position. 1 2. Pull idler away from belt (Figure 6) and remove belt from idler pulley, engine and drive pulley (it may be necessary to turn engine pulley using rewind starter). 3 2 3. Rotate belt fingers out and away from belt and pulley by removing one cap screw and loosening the other. IMPORTANT: Use care when rotating the belt fingers to prevent deformation of parts.
The chute bracket and gear strap are also slotted for vertical adjustment of the discharge chute. Loosen mounting nut and move discharge chute up or down so that chute ring is approximately centered between retainer clip and lower ring. Retighten. 3 1 5 6 Runners 4 7 Runners should be adjusted as conditions require. Raising or lowering runners controls distance scraper blade (auger/impeller housing) is held above surface being cleared. 2 8 1. Position unit on a hard, flat smooth level surface.
Attachment Clutch/Impeller Brake WARNING: AUGER/IMPELLER MUST STOP within 5 seconds when attachment clutch/ impeller brake lever is released or unit damage or serious injury may result. ROTATING PARTS can cut off body parts. Keep hands and feet away. Loose clothing, long hair or scarves can get caught in rotating parts and cause death or serious injury. It is necessary to perform the adjustments with the belt guard removed and extreme care is to be taken to prevent injury.
With the other hand move the traction drive clutch lever toward the handle grip until all cable slack is removed, and hold it there. 3 3. Measure the distance between the lever and handle grip. Proper measurement is 3-1/4 to 3-3/4" (8.25 - 9.52 cm) (Figure 11). Shortening the cable by 1/16" (1.6 mm) with the adjusting sleeve will increase lever-to-handle grip measurement by 1/4" (6.35 mm). 31/4"- 3 3/4" 4 2 5 1 4. Lock adjusting sleeve with jam nut when adjustment is complete.

SECTION 6 - ENGINE 6.1 ENGINE TROUBLESHOOTING The following troubleshooting chart is to be used to isolate engine problems and give possible causes and corrective action responses. TROUBLE Black Exhaust Blue/White Exhaust Difficult Starting Erratic Running Excessive Fuel Consumption High Oil Pressure Knocking Loss of Power or System Low Cranking Power Low Oil Pressure Misfiring Overheating Poor Compression Starts and Stops The troubleshooting key is generic and can be used for several types of engines.
See your engine manual for information on the operation and maintenance of your engine. Follow those instructions for oil and filter changes. 6.2 REMOVING THE ENGINE 1. Drain gasoline. 2. Place unit in the Belt Service Position. 3. Remove both belts from the engine pulleys. Remove pulleys. 4. If the unit has a bracket at the top of the engine for chute/deflector controls, unbolt it. 5. If the unit is equipped with electric starting, remove the starter. 6.
SECTION 7 - REDUCTION DRIVE 7.1 WHEELS AND AXLE The wheels are bolted directly to the axle shaft. To remove the wheels, loosen the bolt and nut. Push the bolt out and slide the wheel hub off of the axle. 7.2 SPROCKET AND CHAIN - 824 MODELS ONLY 1. Place the unit in the Upright Service Position. The 824 models have a reduction sprocket driven by the friction wheel hex shaft (Figure 15). This shaft is removed to change the chain and to provide clearance for inspection. 2. Remove both wheels.
SECTION 8 - FRICTION WHEEL DRIVE 8.1 FRICTION WHEEL NOTE: The 824 Models have a sprocket assembly with chain drive. Slide the sprocket off the shaft and remove (see Figure 19). 1. To replace friction wheel, tip unit up onto housing on a level surface. 8. Remove three cap screws securing friction wheel to hub and remove friction wheel. 2. Remove bottom cover by removing four cap screws. 3. Remove right hand wheel, tire. 4. Remove bearing flange screws on the right hand side of the frame.
8.2 FRICTION WHEEL CARRIER appropriate sections of this manual for more information. The friction wheel carrier is not repairable and is replaced when needed. Inspect the carrier when the friction wheel is serviced. 6. Pull the shaft out of the bushing. 7. Reassemble in reverse order. When installing the drive plate to the hex shaft, use anti-seize on the shaft. 8.3 DRIVE PLATE The drive plate can be removed and inspected when the drive system, friction plate, and axle have been removed.
SECTION 9 - AUGER/IMPELLER 9.1 AUGER/IMPELLER REMOVAL 2. Loosen retaining blade nuts (Figure 20). Place unit in the Belt Service Position. 1. Remove three nuts holding pulley to hub and remove pulley and key. 3. With runners adjusted to their full up position, reposition scraper blade down, flush with runners. 4. Tighten lock nuts. 2. Loosen set screw in hub and remove hub. 9.3 SHEAR BOLTS 3. Remove three nuts holding bearing flange to housing and remove bearing flange (Figure 20).
9.4 DISCHARGE CHUTE NOTE: Chute must rotate freely. To adjust the gears tighten or loosen the lower nut (Figure 21). This will adjust the spring tension on the gears. WARNING: DO NOT put hands or feet near or under rotating parts. Keep clear of discharge opening at all times. WARNING: NEVER direct discharge of material toward bystanders nor allow anyone in front of equipment while unit is in operation. Be familiar with area of operation.
9.5 RUNNERS raise runners so that scraper blade scrapes clean. To reduce tendency of housing to ride up over heavy wet or hard-packed snow, remove runners and re-install with the narrow edge down. CAUTION: Adjust auger/impeller housing height to clear gravel or crushed rock surfaces. Runners should be adjusted as conditions require (Figure 22). Raising or lowering runners controls distance scraper blade is held above surface being cleared.
SECTION 10 - GEAR CASE 10.1 ALUMINUM GEAR CASE 8. Behind rear bronze bushing is a seal which fits into a groove in gearcase. It should be replaced at time of repair. 1. Remove auger/impeller and gear case from housing referring to Auger/Impeller Section. 2. Remove six bolts that hold right and left gear case halves together (Figure 23). 3. If flange bushings need replacement, first remove seals from outside of gearcase halves with a screwdriver.
