After approximately ten hours of operation, a new belt will

stretch and require 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. Remove belt cover

(see Figure 34).

4. Loosen nut on traction idler pulley and move traction idler

pulley towards belt about 1/8 inch (3 mm) (see
Figure 40).

5. Tighten nut.

6. Have someone engage traction drive clutch. Check ten-

sion on belt (opposite idler pulley). The belt should de-
flect about 1/2 inch (12.5 mm) with moderate pressure
(Figure 35).  You may have to move idler pulley more
than once to obtain the correct tension.

7. Reinstall belt cover.

8. Attach the spark plug wire. Before operation, check the

belt tension as follows:

a. Unlock both left and right wheel locks. See “How To Use

The Wheel Lockout” in the Operation section.

b. Move the shift lever to NEUTRAL position.
c. DO NOT engage the traction drive lever.
d. Start the engine.
e. Slowly move the shift lever forward. Watch the axles for

rotation. If the axles rotate, the traction drive belt is too
tight.

f. If the belt is too tight, again adjust the belt. After each

adjustment, check the belt tension before operating.

9. In correct adjustment, the snow thrower will not experi-

ence a loss of power under heavy load and the drive will
automatically disengage when the traction drive lever is
released.
