Place the shift lever in the fastest forward speed position. Remove the hairpin clip which

secures the ferrule to the shift lever.

Thread the ferrule up or down the shift rod until it aligns with the hole in the shift lever behind

the handle panel. Resecure the ferrule with the hairpin clip removed earlier.

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 loo sen the plastic wing knob found on the left side of the chute assembly. Pivot the chute upward or downward before re-tightening the wing knob. See Figure 16 .

Chute Bracket Adjustment

If the spiral at the bottom of the chut e directional control is not fully engaging with the chute assembly, the ch ute bracket can be adjusted. To do so, loosen the two nuts which secure the chute bracket and reposition it sligh tly before retightening the nuts. See Figure 17 .

Figure 17

Drive Control

When the drive control is released a nd in the disengaged “up” position, the cable should have very little slack. It should NOT be tight.

Check the adjustment of the drive control as follows:

1. With the drive control disengaged, push the snow thrower gently forward. The unit should roll freely.

2. Engage the drive control and gently attempt to push the snow thrower forward. The wheels should not turn. The unit should not roll freely.

3. With the drive control disengaged, move the shift lever back and forth between the R2 position and the F6 position several times. There should be no resistance in the shift lever.

If any of the above tests failed, th e drive cable is in need of adjustment. refer to Figure 18 and procee d as follows:

• Loosen the hex jam nut on the aug er control cable “Z” fitting and rotate the coupling end (without turning the cable) of the cable downward to provide more slack or upward to take up slack. See Figure 18 .

Skid Shoes

NOTE: The space between the skid shoes and the ground can be adjusted. See Figure 19. For close snow removal, place skid shoe in the low position. Use middle or high position when area to be cleared is uneven.

NOTE: Some models are equipped with reversible skid

shoes and may be turned over to increase their lifespan. See Figure 19.

CAUTION: Loose gravel can be picked up

and thrown by the auger, causing injury to the operator and bystanders and/or damage to the snow thrower and surrounding property.

• Adjust skid shoes by loosening the four he x nuts (two on each side) and carriage bolts. Move skid shoes to desired position.

• Make certain the e ntire bottom surface of skid shoe is against the ground to avoid uneven wear on the skid shoes. Retighten nuts and bolts secu rely.

• Retighten the hex jam nut and repeat all three tests to verify proper adjustment has been achieved.

Auger Control

Refer to Auger Control Test on Page 12 to adjust the auger control.
