Operation DEFLECTOR The distance of the discharged snow is mainly controlled by the position of the deflector. (Engine speed also affects distance of discharge.) The more the deflector is tilted UP, the farther snow will be thrown. 1. Rotate the adjustment knob (C, Figure 9) counterclockwise to loosen then adjust the deflector to the desired position and tighten the deflector adjustment knob by turning it clockwise to secure the deflector in position.
Operation CLEARING A CLOGGED DISCHARGE CHUTE Hand contact with the rotating auger/impeller inside the discharge chute is the most common cause of injury associated with snowthrowers. DO NOT use your hand to clean out the discharge chute. To clear the chute: 1. Stop the engine. Remove the key WARNING Never store the unit, with gasoline in engine or fuel tank, in a heated shelter or in enclosed, poorly ventilated enclosures.
Regular Maintenance MAINTENANCE SCHEDULE MAINTENANCE REQUIRED FREQUENCY NOTES Check / Lubricate Hand Linkage. 10 Hours 10W Oil Lubricate snowthrower. 10 Hours 10W Oil and Grease Check tire pressure. Monthly Change engine oil.*+ 50 Hours; 20 psi (1.37 bar) See Engine Manual Yearly See Engine Manual 4-6 Hours See page 24 Yearly Lithium Grease Check auger gear case lubrication.** 25 Hours Benalene Grease Lubricate Auger Shaft.*** 10 Hours Lithium Grease Clean or replace spark plug.
Regular Maintenance LUBRICATION IMPORTANT NOTE It is very important that grease fittings on the auger shaft are lubricated regularly. If auger rusts to shaft, damage to worm gear may occur if shear pins do not break. A To prevent wheels rusting to axles, it is also necessary to remove the wheels and grease the axles regularly. Remove wheels and grease axles once each year. Apply 5W-30 synthetic motor oil sparingly to the friction disk drive hex shaft (A, Figure 15).
Regular Maintenance CHECK / LUBRICATE LINKAGE Check the function of the Hand controls: the controls should function as described in the CONTROLS section. It is critical for the safe operation of the unit that the controls disengage when released. Lubricate as shown in figure 18. IMPORTANT NOTE If the controls do not function properly, lubricate them. If lubrication does not rectify the problem, see your dealer. Under no circumstances should the unit be used if the controls are not functioning properly.

Troubleshooting TROUBLESHOOTING WARNING This section provides troubleshooting and service instructions. Locate the problem and check the possible cause/remedy in the order listed. Also, refer to the engine manufacturer’s Owner’s Manual for additional information. Before performing any adjustment or service to snowthrower, stop the engine and wait for moving parts to stop. Remove the key. To prevent accidental starting, disconnect the spark plug wire and fasten away from the plug.
Troubleshooting PROBLEM POSSIBLE CAUSE REMEDY 1. Chute deflector too low. 1. Adjust deflector as necessary. 2. Ground speed too fast. 2. Use slower speed selector setting. 3. Snowthrower discharge chute clogged. 3. STOP engine and REMOVE the key. DISCONNECT the spark plug wire. Clear auger using clean-out tool. See warning in SAFETY RULES. 4. Auger belt loose or worn. 4. Check auger drive belt adjustment Poor traction 1. Tires slipping. 1. Check tire pressure and tread.
Adjustments AUGER DRIVE ADJUSTMENT WARNING Do not over-tighten, as this may lift the lever and cause auger drive to be engaged without depressing the Auger Control. 1. With the drive lever released, the hook (B, Figure 20) should barely touch the lever (C) without raising it. There can be a maximum 1/32” clearance as shown. 2. To adjust, loosen nut (D) by holding the adjusting flats (A) and turning nut (D). Turn adjustment flats and hold screw.
Adjustments Run-In Adjustment ALL MODELS 1. After 5 hours of use, check for proper adjustment. Readjust clutch cable if necessary by increasing tension on cable. A small amount of arm movement is permissible if unit passes operating checks described in the Warning above. 8. Note the position of the friction wheel (A, Figure 24). The correct distance from the right side of the friction wheel to the outside of the frame is 4-5/16” (10.95 cm).
Adjustments BELT ADJUSTMENT B Auger Drive Belt If your snowthrower will not discharge snow, check the control cable adjustment. If it is correct, then check the condition of the auger drive belt. If it is damaged or loose, replace it (see Belt Replacement in this section of the manual). 1. Disconnect spark plug wire. 2. Remove screw (B, Figure 25) from belt cover (A). Remove belt cover (A). 3.
Service SHEAR PIN REPLACEMENT WARNING Do not go near the discharge chute or auger when the engine is running. Do not run the engine with any cover or guard removed. B A Under most circumstances, if the auger strikes an object which could cause damage to the unit, the shear pin will break. (This protects the gear box and other parts from damage.) The shear pins are located on the auger shaft as shown in Figure 27.
Service BELT REPLACEMENT A Auger Drive Belt B F The drive belts are of special construction and must be replaced with original factory replacement belts available from your nearest authorized service center. Some steps require the assistance of a second person. If the auger drive belt is damaged, the snow thrower will not discharge snow. Replace the damaged belt as follows. C L D K E 1. Disconnect the spark plug wire. A 2. Loosen the capscrews (A, Figure 28) on each side of the bottom panel (B).
Service 9. Remove hair pin (A) and slide rod (B) backward about 3 inches (until shaft separates from the worm drive). 11. Lift the Chute and rotator (A, Figure 33) off of the auger housing. B A A Figure 31. Rotator Shaft Removal A. Pin, Hair B. Shaft 10. Remove two 5/16-18 KEPS hex nuts (A, Figure 32), and two 5/16-18 x 1-1/2 carriage bolts (B) securing the offset tube (C) to the tube support bracket (D). A C Figure 33. Chute and Rotator Removal A. Chute and Rotator 12.
Service NOTE: To assemble the auger housing to the frame, have someone hold the auger clutch lever in the ENGAGED position. This will move the idler arm and pulley enough to allow the auger drive pulley to move back into position. 15. Assemble the auger housing (C, Figure 34) to the frame with the four upper taptite screws (A) that were removed in step 12. Tighten the two lower taptite screws (B). Tighten all taptite screws to 40-50 lb-in (4,5-5,6 Nm). 16.
