Replacing Motor Brushes - Grizzly G0725 Owner's Manual

Replacing Motor
Brushes
The jointer 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 31) 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 P0725024-1.
