5. Loosen the four flange bolts that secure both skids to
the auger side plates (Fig. 10) until the skids slide up
and down easily.
6. Support the auger blades so that they are at least
1/8 inch (3 millimeters) off the ground (Fig. 27).

Note: Setting the auger blades too low may result in
damage to the snowthrower that is not covered by the
warranty.
7. Check the scraper adjustment. The scraper should be
1/8 inch (3 millimeters) above and parallel to a level
surface.
Note: Setting the scraper too low may result in damage
to the snowthrower that is not covered by the warranty.
For Concrete and Asphalt Surfaces:
If the snowthrower does not clear the snow close enough to
the pavement, adjust the skids to lower the scraper; if the
pavement surfaces are cracked, rough, or uneven, adjust the
skids to raise the scraper.
For Gravel Surfaces:
Support the auger blades a few inches (centimeters) above
the ground, and adjust the skids to prevent the snowthrower
from picking up rocks.
8. To adjust the scraper, loosen the carriage bolts that
secure the scraper to the auger housing (Fig. 27), level
the scraper, and tighten the carriage bolts.
9. Move the skids down as far as possible.
10. Tighten the two front flange bolts that secure both skids
to the auger side plates.
11. Connect the wire to the spark plug.
Adjusting the Traction Drive
Belt
Check the traction drive belt for the proper tension after the
first operating hour, after every five operating hours
thereafter. Adjust the belt when necessary or whenever you
replace it.

1. Loosen the upper jam nut that secures the traction cable
to the mounting bracket (Fig. 28).

2. Rotate the bottom jam nut upward to increase the belt
tension (Fig. 28).
Note: When you adjust the cable, always rotate the jam
nut one full turn at a time.
3. Tighten the upper jam nut against the bracket.
4. Check the tension of the belt by operating the
snowthrower.
Note: The snowthrower should begin to move forward
when you press the traction control lever about halfway
down toward the handgrip.
5. Stop the engine and repeat steps 1 through 4 until you
achieve the proper adjustment.
Important
Do not adjust the belt too tightly; a tight
belt can cause the snowthrower to creep even after you
release the traction control lever. If this occurs, decrease
the belt tension.
Adjusting the Auger/Impeller
Drive Belt
Operating the snowthrower with an auger/impeller drive
belt that slips decreases the snowthrowing performance and
damages the belt. Check the auger/impeller drive belt for
the proper tension after the first operating hour, after every
five operating hours thereafter. Adjust the belt when
necessary.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug and ensure that
the wire does not contact the plug (Fig. 32).
3. Remove the three flange-head bolts that secure the belt
cover to the engine frame and slide the belt cover up the
cables (Fig. 5).
4. Depress the auger/impeller drive control lever (Fig. 13).
