SERVICE
General
This section covers the most common service adjustments or procedures that may need to be made during the life of your machine.
If you require additional machine service not included in this section, please contact Woodstock International Technical Support at (360)
Changing Motor Brushes
This sander has a permanent magnet motor that uses car- bon brushes for operation. These brushes normally wear out over time and eventually need to be replaced.
Symptoms indicating that the brushes have worn beyond their usable life may include a loss of power, inconsistent operation of the motor (motor cuts in and out inexplicably), or an inability of the motor to start.
If you are having trouble with the performance of the motor, first refer to Troubleshooting on Page 22 to deter- mine if the motor brushes must be replaced.
A pair of new brushes can be purchased from your Shop Fox dealer by requesting part #W1831033A. The replacement procedure can usually be done in about 15 minutes. When replacing the brushes, we recommend replacing them one at a time so you can keep track of which wire connects to each brush.
Please note: The brush assemblies have locating prongs (see Figure 15) that insert into the motor to hold the brush housing in position. Take care when removing the brush assemblies to pull them out first instead of just up.

Make sure that your machine is unplugged during all service proce- dures! If this warning is ignored, seri- ous personal injury may occur.
