BELT ADJUSTMENT
Traction Drive Belt
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.
Auger Drive Belt
If your snow thrower 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).

depressing the auger control.

sion on belt which is opposite idler pulley (B B, Figure 27). Belt should
