Replacing Motor Brushes - Grizzly G0725 Owner's Manual

Replacing Motor
Brushes
The jointer has a universal motor that uses carbon
brushes that normally wear out over time. If you are
having trouble with the performance of the motor,
refer to Troubleshooting (Page 34) 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 P0612024-1.

While facing the rear of the jointer, tip it away

Note: When you remove the brush caps, a
spring will pop out of the socket; the carbon
brush is firmly attached to this spring. When
you buy a new brush kit, you will get a pair of
brush/spring assemblies. Do not separate the
brush from the spring.

Check the brushes for wear. If a brush is
worn to less than

brushes.
7.
Insert the brush assemblies, positioning them
so they slide into the slots built into the sock-
ets.
8.
Individually, press each brush cap against its
spring, pushing it into the socket and turning
the brush cap to lock it in the motor housing.
9.
Re-install the motor cover.
10. Test run the jointer.
—If the jointer runs properly, you are done.
—If the motor does not start, either the brush-
es are not correctly aligned in the sockets
or there is another problem with the motor
or wiring. Double check all wire connections
first, then refer to the Troubleshooting on
Page 34 for assistance.
