SECTION 5: MAKING ADJUSTMENTS

WARNING: NEVER attempt to make any adjustments while the engine is running, except where specified in the operator’s manual.

Auger Control

Refer to Auger Control Test on page 8 to adjust the auger control.

Chute Assembly

The distance snow is thrown can be adjusted by changing the angle of the chute assembly. To do so, stop the engine by removing the ignition key and loosen the plastic wing knobs found on either side of the discharge chute. Pivot the chute upward or downward before re-tightening the wing knobs.

Tire Pressure

•The tires are over-inflated for shipping purposes. Before operating, check tire pressure and reduce, if necessary, to between 15 psi and 20 psi.

NOTE: If the tire pressure is not equal in both tires, the unit may pull to one side or the other.

Traction Control and Shift Lever

•To check the adjustment of the traction control and shift lever, proceed as follows:

•With the engine off, move the shift lever all the way forward to sixth (6) position. With the traction control released, push the snow thrower forward. The unit should move forward freely. Then engage the traction control grip. 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 wheels should keep turning.

•If you feel 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 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.

WARNING: Drain the gasoline out of snow thrower engine, place a piece of plastic film under the gas cap to avoid spillage before beginning the job.

To test further for correct adjustment, if necessary, proceed as follows:

•Tip the snow thrower forward, allowing it to rest on the auger housing.

•Remove the frame cover underneath the snow thrower by removing 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 traction control engaged, the friction wheel must contact the drive plate. See Figure 7.

If adjustment is necessary:

•Loosen the jam nut on the traction drive cable and thread the cable in or out 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.

Shift Rod

To adjust the shift rod, proceed as follows.

•Remove the hairpin clip and flat washer from the shift handle under the handle panel.

•Place shift lever in sixth (6) position or the fastest forward speed.

•Push shift arm assembly down as far as it will go

•Rotate the ferrule up or down on the shift rod as necessary until the ferrule lines up with the upper hole in the shift lever. See Figure 8.
