TO REPLACE BELTS (See Fig. 20)
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 Sears 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 construction
and should be replaced by original equipment manufacturer
(OEM) belts available from your nearest Sears service
center/department. Using other than OEM belts can cause
)ersonal 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
position and hold the snow thrower
handles. Serious personal injury and/
or damage to the unit could occur if the
snowthrower should fall during the belt
changing process.
