The traction drive belt has constant spring pressure and does not require
an adjustment. If the traction drive belt is slipping, replace the belt. See au-
thorized dealer.

If your snowthrower will not discharge snow, check the control cable adjust-
ment. If it is correct, then check the condition of the auger drive belt. If it is
damaged or loose, replace it (see authorized dealer).
