Craftsman 247.88845 Service And Maintenance, Wheel drive control, Chute Bracket, Auger Control

SERVICE AND MAINTENANCE

Move the remote chute lever on the control panel forward to pivot the upper chute down; move the lever rearward to pivot the upper chute up.

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.

2.Locate the opening between the axle support bracket and the front frame support (See Figure 21). 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 shift lever.

3.With the wheel drive control engaged, the friction wheel must contact the drive plate. See Figure 21.

4.If there is no friction wheel clearance, or the friction wheel does not solidly contact the drive plate, re-adjust the lock nut on the lower end of the drive cable following the instructions in the Assembly section.

5.Reassemble the frame cover.

Chute Bracket

If the spiral at the bottom of the chute directional control is not fully engaging with the chute assembly, the chute bracket can be adjusted. To do so:

2.Retighten the nuts.
