ADJUSTMENTS
Skid Shoe Adjustment
On smooth surfaces such as concrete or asphalt, the
scraper bar should scrape the surface. On surfaces
such as gravel, the scraper bar should be set high
enough so that it will not pick up debris.
1. Loosen the nuts securing the skid shoes (see
Figure 12).
2. Raise or lower the scraper bar to the desired height.
Use wood blocks to hold the snowthrower in position.
3. Set the skid shoes so that they are in contact with the
ground and tighten the skid shoe nuts.
Electric Chute Rotator Gear
1. Remove the plastic cover (B, Figure 13) and loosen
the three taptite screws (A) securing the electric
spout rotator motor.
2. Adjust the motor so that it meshes with the discharge
chute ring gear and tighten the adjustment screws
(A).

Shear Bolts
Refer to Figure 10 for discharge fan shear bolt, two stage
only (grade 5 hardness, 1/4" x 1"). Refer to Figure 11 for
auger shear bolt , al models (one in each auger-special-
ized, grade 5 hardness, 5/16" x 2-1/2").
Check for excessive wear. The shear bolt will break if
the auger or fan hits a solid object. If this happens:
1. Stop the snowthrower and tractor immediately.
2. Stop the engine, lock the parking brake, and remove
the key.
3. Remove the broken shear bolt.
4. Install a new shear bolt. Make sure the replacement
shear bolt is Grade 5 hardness.
5. Locate and correct the cause of the shearing.
