Changing Motor Brushes
This sander has a permanent magnet motor that uses
carbon 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 26 to
determine 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.
