Lower Chute Crank
Support Bracket Adjustment
If the spiral at the base of the lower chute crank isn’t
fully engaging with the notches in the lower chute
assembly, the support bracket can be adjusted inward
or outward as follows:
1. Loosen, but do NOT remove the two hex nuts
which secure the support bracket to the snow
thrower housing. See Figure 22.
2. Adjust the support bracket inward or outward so
that the spiral is fully engaged in the notches on the
chute before retightening the hex nuts.

SECTION 8: LUBRICATION
Auger Shaft
• At least once a season, remove the shear bolts on
the auger shaft. Oil or spray lubricant inside and on
the plastic bearings on the shaft and near the holes
where the shear bolts were removed before
reattaching them. See Figure 23.

Chute Directional Control
• The spiral on the end of the lower chute crank, the
base of the discharge chute itself and the joint
blocks which connect the lower and upper chute
cranks should be lubed with multi-purpose
automotive grease once a season. See Figure 24.
