The distance snow is thrown can be adjusted by 
changing the angle of the chute assembly. Move the 
chute tilt control forward to decrease the distance, 
toward the rear to increase.

Refer to Auger Control Test in the Operating Section to 
adjust the auger control.

To check the adjustment of the traction 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 traction 
control lever released, push the snow thrower 
forward. The unit should roll forward. Then engage 
the traction control grip. The wheels should stop 
turning.

•

Now release the traction control grip 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 traction control cable and 
unthread the cable one turn.

•

If the wheels do not stop when you engage the 
traction control clutch grip, loosen the jam nut on 
the traction 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.

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.

•

Remove the frame cover underneath the snow 
thrower by removing the six self-tapping screws.

•

With the traction control released, there must be 
clearance between the friction wheel and the drive 
plate in all positions of the shift lever. 

•

With the traction control engaged, the friction wheel 
must contact the drive plate. See Figure 10.

If adjustment is necessary:

•

Loosen the jam nut on the traction drive cable. 
Adjust the cable as necessary.

•

Retighten the jam nut to secure the cable when 
correct adjustment is reached. 

•

Reassemble the frame cover.

NOTE: If you placed plastic film under the gas cap, be
certain to remove it before operating the snow thrower.
