SERVICE AND ADJUSTMENTS

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 qualifi ed service center.

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 dealer. 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. Se-
rious personal injury and/or damage to
the unit could occur if the snow thrower
should fall during the belt chang

ing

process.

the square hole in idler arm and rotate ratchet clockwise
to relieve tension.

belt around pulleys and inside belt keepers.

carefully for proper routing of belts. If auger belt has
become dislodged from the pulley (by catching the idler
arm bracket while bringing snow thrower together),
separate the snow thrower and re peat step 10. Belt
must be fully seated in pulley groove when bring ing
the snow thrower together.

tighten securely.
