Replacing Motor
Brushes
The G0821 has a universal motor that uses car-
bon brushes that normally wear out over time. If
you are having trouble with the performance of
the motor, refer to
Troubleshooting (Page 33) to
determine if the motor brushes must be replaced.
You can order a new brush kit (two brush assem-
blies) from Grizzly. The part number for the brush
kit is

To replace motor brushes:
1. DISCONNECT MACHINE FROM POWER.
2. Tip jointer body until it gently rests on fence
assembly.
3. Remove (4) Phillips head screws securing
motor cover to jointer base. Remove cover
and set it aside.
4. Take this opportunity to clear dust and debris
from inside jointer.
Note:
When brush caps are being removed,
a spring will pop out of the motor socket;
a spring is firmly attached to each carbon
brush. Do not separate brush from spring.
6. Use a ruler to measure wear of each carbon
brush. If either brush is worn to less than
3
/
32
"
in length, replace both brushes.
7. Insert new brush assemblies, positioning
them to slide into slots in motor sockets.
Individually, press each brush cap against
its spring, pushing it into motor socket and
turning each brush cap to lock it into motor
housing.
8. Re-install motor cover.
9. Test run jointer.
— If jointer runs properly, you are done.
— If motor does not start, either new brushes
are not correctly aligned in each socket,
or there is another problem with motor or
wiring. Double-check all wire connections
first, then refer to
Troubleshooting on
Page 33 for assistance.
