2.
Pull back each spring and pull the brush out of the
holder. Keep the lead wire connected.
3.
Turn the pad driver and look at the part of the
commutator that the brushes touch.
4.
Take the machine to a Clarke authorized repair
location if you see any of the following conditions:
1.) Small holes in the surface of the commuta-
tor. See Figure 6 "A".
2.) Uneven color. Look for an even dark brown
color. Clean areas or very dark areas
indicate a problem. See Figure 6 "B".
3.) High mica. The mica insulation must be
lower than the commutator bars. See
Figure 6 "C".
6.
Replace all four carbon brushes if any carbon
brush is shorter that 7/16 inch. To replace the
carbon brushes in the motor, follow this procedure:
1.) Remove the screws. Replace the brush and
lead. Install the screw.
2.) Use a hook to pull the spring out of the way.
Install the brush into the slot. Put the
spring into position on the end of the brush.
The lead must not prevent free movement of
the brush in the holder.
3.) Install the covers and screws.
Rectifier
If the machine trips circuit breakers, blows fuses or
runs at half speed, the rectifier may be defective. Take
the machine to an authorized repair location to have a
Clarke authorized repair person replace the rectifier.
