6. If the space between the coils is not 0.010 in.
(0.25 mm), adjust the cables as follows:
A. Loosen the upper jam nut that secures the
auger/impeller cable to the mounting bracket
(Fig. 28).
B. Rotate the bottom jam nut upward to increase the
belt tension.
C. Tighten the upper jam nut against the bracket.
7. Repeat steps 4 through 6.
8. Check the impeller brake arm clearance by releasing the
auger/impeller drive control lever.
Note: With the lever released, there should be at least
1/8 in. (3 mm) clearance between the tab on the
impeller idler arm and the brake arm (Fig. 30).

Important
If there is less than 1/8 in. (3 mm) clearance
between the tab on the impeller idler arm and the brake
arm, replace the belt. Refer to Replacing the Drive Belts on
page 21.

Danger
Improperly adjusting the auger/impeller drive belt
may cause injury if the auger/impeller continues to
turn after you release the control lever. A rotating
impeller or auger can cut off or injure fingers or
hands.
Keep your face, hands, feet, and any other part
of your body or clothing away from moving or
rotating parts.
Maintain the proper impeller brake arm
clearance.
Do not adjust the auger/impeller drive belt too
tightly. If the auger/impeller continues to turn
after you release the control lever, decrease the
belt tension.
9. Install the belt and the cable covers.
10. Check the belt tension by operating the auger/impeller.
11. If belt still slips, replace it. Refer to Replacing the
Drive Belts on page 21.
12. Connect the wire to the spark plug.

Replacing the Drive Belts

If the auger/impeller drive belt or the traction drive belt
