an adjustment of the belt tension. Also,
if your snow thrower experiences a loss
of power under heavy load, check the
condition of the traction drive belt. if it is
damaged or loose, replace it (see "How
To Replace The Belts" in this section of
the manual).
1. Disconnect spark plug wire.
2. Unlock both left and right wheel
locks. See "How To Use The Wheel
Lockout" in the Operation section.
3. Remove screw from belt cover.

and move traction idler pulley to-
wards belt about 1/8 inch (3 mm)

5. Tighten nut.
6. Have someone engage traction
drive clutch. Check tension on belt
(opposite idler pulley). The belt
should deflect about 1/2 inch (12.5
