Wheel Drive control
Refer to Adjusting Drive and Auger Controls on page 12 of the Assembly
instructions to adjust the wheel drive control. To further check the adjustment,
proceed as follows:
1. With the snow thrower tipped forward (be certain to run the fuel tank empty
before tipping the unit forward), remove the frame cover underneath the
snow thrower by removing the four self-tapping screws which secure it to
the engine frame. See Figure 26.
2. Locate the opening between the axle support bracket and the front frame
support. See Figure 27. Looking through this opening, with the wheel drive
control released, there must be clearance between the friction wheel and
the drive plate in all positions of the speed selector lever.
3. With the wheel drive control engaged, the friction wheel must contact the
drive plate. See Figure 27.

contact the drive plate, re-adjust the lock nut on the lower end of the drive
cable following the instructions in Adjusting Drive and Auger Controls on
page 12 of the Assembly section.
5. Reassemble the frame cover.
