The shave plate and skid shoes on the bottom of the snow thrower are
subject to wear. They should be checked periodically and replaced
when necessary.
Skid Shoes
NOTE: The skid shoes on this machine have two wear edges. When
one side wears out, they can be rotated 180° to use the other edge.
Remove the six carriage bolts and hex nuts that secure the two 1.
skid shoes to the sides of the auger housing. Refer to Figure 19.
Position the new skid shoes and secure with the carriage bolts

Shift rod
If the full range of speeds (forward and reverse) cannot be achieved,
refer to Figure 20 to the left and adjust the shift rod as follows:
Looking underneath the handle panel, note which of the three 1.
holes in the shift lever the ferrule is inserted into. Also note the
direction of insertion. Then remove the internal cotter pin and flat
washer from the ferrule and withdraw the ferrule from the shift
lever. See Figure 20.
Place shift lever in sixth (6) position or fastest forward speed.
2.
Push shift rod and shift arm assembly down sharply as far as it 3.
will go to put the drive into the fastest forward position.
As necessary, rotate the ferrule up or down the shift rod until the
4.
ferrule lines up with the hole from which it was earlier removed.
See Figure 20.
From the direction noted earlier, insert the ferrule into the proper hole.
5.
Reinstall the washer and the internal cotter pin. 6.

The distance snow is thrown can be adjusted by adjusting the angle of
the chute assembly. Refer to the Operation section for instructions.
