ADJUSTMENT/REPAIR
BELT ADJUSTMENT
Belts stretch during normal use. If you need to adjust the
belts due to wear or stretch, proceed as follows.
TRACTION DRIVE BELT
Traction drive belt has constant spring pressure and does not
require adjustment.
Replace belt if it is slipping. (See "Belt Replacement" in this
section of the manual).
AUGER DRIVE BELT
If your snow blower will not discharge snow, check the control
cable adjustment. If it is correct, then check the condition of
the auger drive belt. It may be damaged or loose. If it is
damaged, replace it (see Belt Replacement in this section of
the manual). If the auger drive belt is loose, adjust as follows.

sion on belt (opposite idler pulley). Belt should deflect
