Adjusting/Replacing Belts - Grizzly G0725 Owner's Manual

Adjusting/Replacing
Belts
The Model G0725 uses belts to drive both the
cutterhead and the dust collection fan. When
these belts are misaligned, damaged, or not
tensioned correctly, the jointer will not function
properly.
This sub-section describes how to service these
belts. You can order replacement belts from
Grizzly. The part number for the drive belt is
P0725070; the part number for the fan belt is
P0725092.

To re-align or replace cutterhead belt:
1.
DISCONNECT MACHINE FROM POWER!
2.
While facing the rear of the jointer, tip it away
from you until it rests on the fence assembly.
3.
Remove the Phillips screws fastening the
motor cover to the jointer base. Lift the cover
off and set it aside.
4.
Remove all dust and debris from the motor
and belt areas.
5.
Inspect the cutterhead belt for proper tension,
alignment and condition.
Note: The belt is properly tensioned if it
deflects no more than
down on middle of the belt with moderate
pressure from your thumb or forefinger.
The belt is properly aligned if it lies flat and
straight on the motor shaft and drive pulley.
Belt damage will be evident on inspection.
