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.
