12.2 Motor Brushes
Referring to Figure 28:
Periodically inspect the two carbon brushes located
at each side of the motor. If brushes need
replacing, replace both at the same time.
A heavily worn or damaged
brush, if allowed to remain, may eventually
cause damage to internal motor elements.
1. Disconnect lathe from power.
2. Unscrew cap (A, Figure 28) using a
screwdriver or coin, and withdraw brush.
3. Inspect brush. Replace brush if any of the
following are seen: Brush is worn 1/4" (6mm)
or more, collapsed spring, broken lead in
spring, abnormal discoloration, signs of
breakage, burning or crumbling.
4. Reinsert brush, or install new one, and screw
in cap.
5. Repeat inspection for brush on opposite side
of motor.
