NOTE: Make certain to check for correct adjustment of the shift rod as instructed in the Final Adjustments section before operating the snow thrower.

Drive Wheels

The wheels may be adjusted for two different methods of operation. Follow the steps below for adjustment. See Figure 22.

Figure 22

One Wheel Driving

On the right side of the unit, place click pin in the outside axle hole only. Do not place pin through wheel hub.This position gives power drive to the left wheel only, making the unit easier to maneuver.

Both Wheels Driving

Rotate wheel assembly to align hole in the hub with the inner hole on the axle shaft. Insert click pin in the hole. Outer axle shaft hole should be visible.

IMPORTANT: NEVER operate the snow thrower with the click pin inserted through both the RIM and the OUTSIDE HOLE in the axle. Doing so can result in serious damage to the drive system.

SECTION 7: MAINTAINING YOUR SNOW THROWER

WARNING: Before lubricating, repair- ing, or inspecting, disengage all clutch levers and stop engine. Wait until all mov- ing parts have come to a complete stop. Disconnect spark plug wire and ground it against the engine to prevent unintended starting.

Lubrication

Engine

Refer to the separate engine manual packed with your unit for all engine lubrication instructions.

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

Gear Shaft

Lubricate the gear shaft with a good all-weather multi-purpose light grease at least once a season or after every 25 hours of operation.

IMPORTANT: Keep all grease and oil off the friction wheel and drive plate.

Wheels

Oil or spray lubricant into bearings at wheels at least once a season. Pull click pin, remove wheels, clean and coat axles with a multipurpose automotive grease. See Figure 23.
