If the discharge chute becomes difficult to rotate or
begins to operate erratically, the chute direction control
rod gears may require adjustment:
1. Loosen the gear bracket mounting nuts (Figure 23).
2. Slide the gear bracket into the position that provides
the best engagement between the gears.
3. Tighten the bracket mounting nuts, and check for
smooth operation.
4. Readjust if necessary.
5. Lubricate the Chute Direction Control rod gears with
lithium grease.

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 high enough so that
it will not pick up gravel or debris.
The height of the scraper bar is controlled by raising or
lowering the Skid Shoes (See Figure 24).
1. To raise the scraper bar height, rest the scraper bar on
a strip of wood equal in thickness to the desired height.
2. Make sure the scraper bar is parallel to the ground
surface.
3. Loosen the skid shoe nuts and let the skid shoes drop
to the surface.
4. Tighten the nuts, making sure the Skid Shoes are
adjusted equally and are parallel to the surface.
5. To lower the height of the scraper bar, raise the Skid
Shoes.
6. If the scraper bar becomes worn, it can be adjusted
by loosening the nuts and bolts attaching it to the
snowthrower, making the adjustment, and tightening
the hardware. It may also be replaced by removing
the mounting nuts and bolts attaching it to the
snowthrower.
The scraper bar is adjustable. (See Figure 25). If desired
scraper bar height adjustment cannot be achieved solely
by raising or lowering the skid shoes:
1. Loosen the nuts securing the scraper bar to the auger
housing, and raise or lower the scraper bar until
desired height is achieved.
2. Tighten the nuts, making sure the scraper bar is
parallel with the bottom edge of the auger housing.
