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 multi-purpose automotive grease. The cams can be accessed beneath the handle panel. See Figure 16.

Friction Wheel Rubber

Follow the instructions below to check the condition of the friction wheel rubber every 25 hours of operation.

•Remove the six self-tapping screws from the frame cover underneath the snow thrower.

•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 friction plate. Refer to Figure 10. If it does not make contact, adjust the traction drive cable and recheck the friction wheel.

•Replace friction wheel rubber if necessary. Refer to instructions on page 16.

Drive Belts

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 self-tapping screws.

Carburetor

WARNING: If any adjustments are made to the engine while the engine is running (e.g. carburetor), keep clear of all moving parts. Be careful of heated surfaces and mufflers.

Minor carburetor adjustments may be required to compensate for differences in fuel temperature, altitude and load. Refer to the engine manual for instructions.
