Drive Wheels
The wheels may be adjusted for two different methods
of operation. The adjustment is made by placing the
click pins in one of two different holes on the right side
of the unit. See Figure 16.
One Wheel Driving—Insert the click pin only
through the outside hole of the axle (not the rim) on
the right side of the snow thrower. This position
gives power drive to the left wheel only, making the
unit easier to maneuver.
Both Wheels Driving—Insert the click pin through
the hole in the hub of the rim and the inside hole on
the snow thrower’s right axle. This position is good
for heavy snow as there is power drive in both
wheels.
Figure 16
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.

Lubrication
Before lubricating, 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.

• Oil or spray lubricant into plastic wheel bearings
inside the wheel hubs at least once a season.
Remove wheels, clean and coat axles with a multi-

IMPORTANT:
Keep all grease and oil off the rubber
friction wheel and aluminum drive plate.
Chute Directional Control
The spiral on the end of the chute directional control
and the base of the discharge chute itself should be
lubed with multi-purpose automotive grease once a
season. See Figure 19.
