BELT ADJUSTMENT
Traction Drive Belt
The traction drive belt has constant spring pressure and does
not require an adjustment. If the traction drive belt is slipping,
replace the belt. See “How To Replace The Belts” in the
Maintenance section.
Auger Drive Belt
If your snowthrower will not discharge snow, check the
control cable adjustment. If it is correct, then check the
condition of the auger drive belt. If it is damaged or loose,
replace it (see Belt Replacement in this section of the
manual).

Disconnect spark plug wire.
2.
Remove screw from belt cover. Remove belt cover

Loosen nut on auger idler pulley and move auger idler
pulley towards belt about 1/8 inch (3 mm) (see

sion on belt (opposite idler pulley). Belt should deflect
