Belt Service - Grizzly G0772 Owner's Manual

Belt Service

Over time, belts will stretch and wear. To maintain
efficient power transfer to the blades, make sure
the belts are properly tensioned and in good con-
dition. If belts show any glazing, fraying, or crack-
ing, replace them.
To reduce risk of shock or
accidental startup, always
disconnect machine from
power before adjustments,
maintenance, or service.
Tensioning Scoring Motor Belt
The scoring motor uses a flat belt. Proper tension
of this belt is automatically maintained by a torsion
spring on the motor pivot rod (see Figure 167).

Replacing Scoring Motor Belt
To replace the scoring motor belt, lift the scoring
motor up by pulling it towards the main motor,
relieving the belt tension. Chock the motor in
the up position by placing a 6" long scrap piece
of wood between the motor and the wall of the
motor compartment, as shown in Figure 168,
then replace the belt with a new one. Remove the
chock and lower the motor to apply proper belt
tension.
The scoring motor belt is a standard off-the-shelf
flat belt and can be purchased from Grizzly using
part #P07720538.
