4. Carefully pivot the snow thrower up and forward so that it rests on
the auger housing.

by removing four self-tapping screws which secure it. Refer to
Figure 23.

friction wheel disc. See Figure 27.

FRiCtion Wheel Removal
If the snow thrower fails to drive with the drive control engaged, and
performing the Drive Control Cable Adjustment fails to correct the
problem, the friction wheel may need to be replaced. Examine the
friction wheel for signs of wear or cracking and replace if necessary.
NOTE: Several components must be removed and special tools are
required in order to replace this snow thrower's friction wheel rubber.
Contact the nearest Sears Parts & Repair Center as instructed onpage
2 if your friction wheel rubber needs to be replaced.
WaRning
Before performing any type of maintenance/service, disengage all
controls and stop the 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. Always wear safety glasses during
operation or while performing any adjustments or repairs.
