SECTION 4: MAKING ADJUSTMENTS
WARNING: NEVER attempt to make any adjustments while the engine is running, except where specified in the operator’s manual.
Chute Assembly
The distance snow is thrown can be adjusted by changing the angle of the upper chute. Move the chute tilt control forward to decrease the distance, toward the rear to increase.
Auger Control
Refer to Auger Control Test in the Operating Section to adjust the auger control.
Drive Control and Shift Lever
To check the adjustment of the drive control and shift lever, proceed as follows:
•To check the adjustment of the traction control clutch and shift lever, proceed as follows:
•With the engine off, move the shift lever all the way forward to the highest speed. With the drive control lever released, push the snow thrower forward. The unit should roll forward. Then engage the drive control. The wheels should stop turning.
•Now release the drive control and push the unit again.
•Move the shift lever back to the fast reverse position then all the way forward again. There should be no resistance in the shift lever, and the wheels should keep turning.
•If you have resistance when moving the shift lever or the wheels stop when they should not, loosen the jam nut on the drive control cable and unthread the cable one turn.
•If the wheels do not stop when you engage the drive control, loosen the jam nut on the drive control cable and thread the cable in one turn.
•Recheck the adjustment and repeat as necessary. Tighten the jam nut to secure the cable when correct adjustment is reached.
WARNING: Drain the gasoline out of the snow thrower’s tank, or place a piece of plastic film under the gas cap to avoid spillage BEFORE making the adjustment.
To test further for correct adjustment, if necessary, proceed as follows:
•Tip the snow thrower forward, allowing it to rest on the auger housing. See Figure 9.

•With the drive control released, there must be clearance between the friction wheel and the drive plate in all positions of the shift lever.
•With the drive control engaged, the friction wheel must contact the drive plate. See Figure 10.
If adjustment is necessary:
•Loosen the jam nut on the drive cable. Adjust the cable as necessary.
•Retighten the jam nut to secure the cable when correct adjustment is reached.
•Reassemble the frame cover.
