Belt Service - Grizzly G0853 Owner's Manual

Belt Service

The belts will stretch slightly as the saw is used.
Most of the stretching will occur during the first
16 hours of use, but it may continue through con-
tinued use. To maintain efficient power transfer
to the blades, make sure the belts are properly
tensioned and in good condition. If belts show any
glazing, fraying, or cracking, 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 180–181).

Replacing Scoring Motor Belt
To replace the scoring motor belt, tilt the blade to
45°, have an assistant lift the scoring motor up to
relieve the belt tension, 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 belt is automati-
cally maintained by a cam lock attached to the
motor mounting plate and arbor support bracket
(see Figure 182).
