Figure 6-4.
2. Drain the gasoline from the snow thrower, or place a
piece of plastic under the gas cap.
3. Carefully pivot the snow thrower up and forward so
that it rests on the auger housing. See Figure 6-5.
4. Remove the frame cover from the underside of the
snow thrower by removing four self-tapping screws

Friction Wheel Inspection
If the snow thrower fails to drive with the drive control
engaged, and performing the drive control cable adjust-
ment fails to correct the problem, the friction wheel may
need to be replaced.
NOTE: Special tools are required and several com-
ponents must be removed and in order to replace the
snow thrower’s friction wheel rubber. See an authorized
Service Dealer to have the friction wheel rubber
replaced or phone Customer Support as instructed on
page 2 for information on ordering a Service Manual.
To inspect the friction wheel, proceed as follows:
1. Place a piece of plastic under the gas cap and
tighten securely.
2. Carefully pivot the snow thrower up and forward so
that it rests on the auger housing. See Figure 6-5.
3. Remove the frame cover from the underside of the
snow thrower by removing four self-tapping screws
which secure it. See Figure 6-5.
4. Examine the friction wheel for signs of wear or
cracking. See Figure 6-11.
