IMPORTANT: Do not overfill the gear case, since damage to the seals could result. Be sure the vent plug is free of grease in order to relieve pressure.
Auger Bearings and Shaft
Every season lubricate the auger bearings and the bearings on the side of the frame with light oil. See to Figure 12.
Use oil or spray lubricant into the bearings at the wheels at least once a season. Remove the wheels, one side at a time, and clean and coat axles with multi- purpose automotive grease.
Lubricate the auger shaft at least once a season. To do this:
•Remove the shear bolts on the auger shaft.
•Oil or spray lubricant inside shaft.
•Carefully spin the auger around by hand to disperse the lubricant.
•Reinstall the shear bolts.
Check Friction Wheel Rubber
Follow the instructions below to check the condition of the friction wheel rubber every 25 hours of operation.
•Remove the six
•Visually inspect the friction wheel rubber for excessive wear, cracks, or loose fit on the friction wheel drive hub.
•Also engage the traction control and check if the friction wheel is making contact with the friction plate.
•If it does not make contact, adjust the traction drive cable following instructions and recheck the friction wheel.
•Replace friction wheel rubber if necessary. Refer to instructions in Service Section.
Check V-Belts
Follow the instructions below to check the condition of the drive belts every 50 hours of operation.
•Remove the plastic belt cover on the front of the engine by removing the three
•Visually inspect for frayed, cracked, or excessively worn out belts.
•Replace belts as necessary as outlined in Service Section.
Traction Control / Auger Control Lock
The cams on the ends of the control rods which interlock the traction drive and auger drive clutches must be lubricated at least once a season or every 25 hours of operation using a

WARNING: Before servicing, repairing, or inspecting, disengage all clutch levers and stop engine. Wait until all moving parts have come to a complete stop. Disconnect spark plug wire and ground it against the engine to prevent unintended starting.
nuts have been provided with the snow thrower. Refer to Loose Parts in the Assembly Section.
IMPORTANT: NEVER replace the auger shear bolts with standard hex bolts. Any damage to the auger gearbox or other components, as a result of doing so, will NOT be covered by your snow thrower’s warranty.
Augers
The augers are secured to the spiral shaft with two shear bolts and hex lock nuts. If you hit a foreign object or ice jam, the snow thrower is designed so that the bolts may shear. See Figure 15.
If the augers do not turn, check if the bolts have sheared. Two replacement shear bolts and hex lock
Shave Plate and Skid Shoes
The shave plate and skid shoes on the bottom of the snow thrower are subject to wear. They should be checked periodically and replaced when necessary.
NOTE: The skid shoes on this machine have two wear edges. When one side wears out, they can be rotated 180° to use the other edge.
