HOW TO ADJUST THE BELT TENSION
IMPORTANT: When you release the auger bail, the au-
ger must stop rotating. If the auger does not stop, ad-
just the belt tension as follows:
1. Disconnect the spark plug wire from the spark plug.
2. Remove the belt cover.
3. Loosen the idler pulley nut (see Figure 14).
4. Move the idler pulley to the bottom of the idler arm
slot. If the idler pulley is already in the bottom posi-
tion, replace the auger belt. See How To Replace The
Auger Belt in the Maintenance section.
5. Tighten the idler pulley nut.
6. Install the belt cover.
HOW TO REPLACE THE AUGER BELT
1. Disconnect the spark plug wire from the spark plug.
2. Remove the belt cover.

10. When you release the auger bail, the auger must stop
rotating. Make sure the brake contacts the auger
drive pulley (Figure 14) and that the auger cable
spring (Figure 13) has slack (no tension). If not, check

lows:
S Disconnect the end of the idler spring from the
idler arm (see Figure 14).

S Remove the end of the auger cable spring from
the auger bail (see Figure 13).
S Remove the boot from the auger cable spring.
S Attach the end of the auger cable spring to the
auger bail.
12. To adjust the auger cable spring:
S Install the auger belt to the idler pulley (see
Figure 14).
S Attach the idler spring to the idler arm.
S Loosen the jam nut (see Figure 13).
S Turn the adjuster until the auger cable is slightly
slack.
S Tighten the jam nut.
