5. Take the machine to an authorized repair location if

you see any of the following conditions:

1.) Small holes in the surface of the commuta-

tor. See Figure 4 "A".

2.) Uneven color. Look for an even dark brown

color. Clean areas or very dark areas

indicate a problem. See Figure 4 "B".

3.) High mica. The mica insulation must be

lower than the commutator bars. See

Figure 4 "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 in the same

position as the original brush (the shunt wire

on the brush should be located above the

brush spring.) 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 motor cover.

Rectifier

If the machine has been adjusted, and still blows fuses

and runs at half speed, the rectifier may be damaged.

Take the machine to an authorized repair location to

have a Clarke Technology authorized repair person

replace the rectifier.
