Wheel drive control
Refer to the Adjustment section 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 dry before tipping the unit forward), remove the frame
cover underneath the snow thrower by removing the self-tapping
screws. See Fig. 27.
2. Locate the opening between the axle support bracket and
the front frame support (See Figure 28). 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 28.
