ADJUSTMENT
The auger drive clutch cable should be adjusted so that
there is no slack in the cable when moved slightly from
side to side. To adjust tension on the cable:
1. Loosen adjustment hex nut (Figure 21) by holding the
adjusting flats and turning adjustment hex nut .
2. Tighten adjustment screw by turning adjustment flats
and holding screw. The adjustment screw is a
phillips screw and the head can be held or turned by
inserting a screwdriver through the auger drive clutch
cable spring. Tighten just until slack in cable is
removed.
3. Tighten hex nut securely.
4. Start unit and check auger. Auger must not be
engaged unless auger control is depressed.
5. With engine running, fully depress auger control, the
auger should engage and run normally.
6. Release auger control. Auger must stop within 5
seconds.
7. If auger does not operate properly, stop engine and
recheck clutch cable adjustments.
8. If clutch cable is properly adjusted, auger drive belt
tension may require adjustment. See "Adjusting
Auger Drive Belt" on next page.

DRIVE BELT ADJUSTMENT
The snowthrower is equipped with two drive belts locat-
ed just in front of the engine under the belt cover. Figure
22 shows both belts and idler pulleys. The belt nearest
the engine is the unit traction drive (wheels) belt. The
belt farthest from the engine is the auger/ impeller drive
belt.
The traction drive belt has constant tension provided by
a spring-loaded idler pulley arm, and is non-adjustable.
This belt rotates whenever the engine is running, and
provides power to the traction drive disc, which also
rotates constantly while the engine is running.
The auger drive belt tension may be adjusted by moving
the auger drive idler pulley. See “Adjusting Auger Drive
Belt” on next page.
