Replacing Motor
Brushes
Your jointer has a single phase universal motor
that uses carbon brushes. Under normal opera
-
tion these brushes wear out. Refer to the trouble
-
shooting guide 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.
Refer to the parts diagram in this manual when
replacing worn brushes. If you need assistance
call Grizzly Tech Support at (570) 546-9663.
To replace motor brushes:
1. DISCONNECT THE JOINTER FROM THE
POWER SOURCE.
2. While facing the rear of the jointer, tip it away
from you until it rests on the fence assem
-
bly.
3. Remove the four Phillips screws fastening
the motor cover to the jointer base. Lift the
cover and set it aside.
4. Take this opportunity to clear dust and debris
from inside the jointer.
5. Use a dime to unscrew the brush caps. (See
Figure 47 to locate the brush caps.)
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.
6. Check the brushes for wear. If a brush is
worn to less than
3
/32" in length, replace both
brushes.
7. Insert the brush assemblies, positioning them
so they slide into the slots build into the sock
-
ets.
8. Press the brush cap against the spring, push
it into the socket and turn the brush cap to
lock it in the motor housing.
9. Replace the motor cover and tighten the
Phillips screws.
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. Refer to the
Troubleshooting
section for assistance.
