TO REPLACE BELTS
The auger and traction drive belts are not adjustable. If the
belts are damaged or begin to slip from wear, they should
be replaced. It is recommended that the belt(s) be replaced
by a service center/department.
NOTE: It is recommended that both the auger and traction
drive belt be replaced at the same time.
The V-belts on your snow thrower are of special con struc-
tion and should be replaced by original equipment man u-
fac tur er (OEM) belts avail able from your nearest service
center/department. Using other than OEM belts can cause
personal injury or damage to the snow thrower.
WARNING: Belt replacement requires
separation of the snow thrower. While
separating the auger housing from the
frame assembly, it is important that an
assistant stand in the operating po si tion
and hold the snow thrower han dles. Serious
personal injury and/or damage to the unit
could occur if the snow thrower should fall
during the belt chang ing process.
BEFORE REPLACING BELTS
1. REMOVE GASOLINE FROM FUEL TANK - Drain
gasoline from fuel tank into a suitable container, outdoors,
away from fire or flame. Wipe up any spilled gasoline.
2. REMOVE DISCHARGE CHUTE - Remove lock nut
securing chute rotator head to mounting bracket to allow
chute rotator head to be raised and discharge chute to
