TO ADJUST
THE CHUTE CRANK ASSEMBLY
If you cannot rotate the chute crank fully to
the left and to the right, you need to adjust
the chute crank (see Figure 10).
1. Loosen both 1/2” nuts, using 1/2”
wrenches, on the crank adjusting brack-
et.
2. Swivel the crank adjusting bracket to al-
low 1/8” clearance between the notch in
the flange and the outer diameter of the
worm.
3. Once this clearance is set, tighten the
nuts.

TO REMOVE BELT COVER
1. Remove the belt cover (see Figure 11) by
removing the ten screws. There are five
screws on the front of the belt cover, two
screws on the top of the belt cover, and
three screws on the bottom of the belt
cover. The front screw on the bottom of
the belt cover is shorter than the rear and
top screws).
2. Pull the belt cover away from the snow
thrower.

TO ADJUST THE DRIVE BELT
If the motor drive pulley and the auger drive
pulley are not aligned properly, excessive
belt wear will occur. To check the pulley
alignment, proceed as follows:
1. Remove the belt cover (see “To Remove
Belt Cover”).
2. Place a straight edge approximately 16”
long across the large auger pulley, con-
tacting two points and extending to the
motor pulley (see Figure 12). The outside
of the motor pulley must be flush with the
straight edge. If the pulleys are aligned,
skip to the last step).
