SERVICE AND ADJUSTMENTS

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 construc- tion and should be replaced by original equipment manu- facturer (OEM) belts available 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 position and hold the snow thrower handles. Serious personal injury and/or damage to the unit could occur if the snow thrower should fall during the belt changing process.

2.REMOVE DISCHARGE CHUTE - Loosen lock nut securing chute rotator head to mounting bracket to allow chute rotator head to be raised and discharge chute to be removed from snow thrower. See Fig. 19.
