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 qualified 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 construction and should be replaced by original equipment manufacturer (OEM)
belts available 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 (1) from
the frame assembly (2), it is important that an assistant stand in the op er at ing position and hold the snow thrower
handles (3). Serious personal injury and/or damage to the unit could occur if the snow thrower should fall during the
belt chang ing process.
