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.
Follow the instructions below. Examine the friction wheel for
signs of wear or cracking and replace if necessary:
1. Allow the engine to run until it is out of fuel.
2. Place the shift lever in third Forward (F3) position.
3. Carefully pivot the snow thrower up and forward so that it
rests on the auger housing.
4. Remove the frame cover from the underside of the snow
thrower by removing the self-tapping screws which secure
it. Remove the right-hand wheel by removing the screw
and bell washer which secure it to the axle. See Fig. 8-8.
