Belt Service - Grizzly G0764Z 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
Proper tension of the scoring motor flat belt is
automatically maintained by a spring on the motor
pivot rod (see Figures 145 and 146).

Replacing Scoring Motor Belt
To replace the scoring motor belt, have an assis-
tant lift the scoring motor up to relieve the belt ten-
sion, then replace the belt with a new one. When
the motor is lowered, proper belt tension will be
applied by the spring.
Tensioning Main Motor Belt
Proper tension of the main motor V-belt is auto-
matically maintained by a cam lock attached
to the motor mounting plate and arbor support
bracket (see Figure 147).
