Carbon Brushes

The brushes in your tool have been engineered for many hours of dependable service.

To prepare the brushes for use, run the tool at full speed for 5 minutes under no load. This will properly “seat” the brushes, and extend the life of the tool.

To maintain peak efficiency of the motor, examine the brushes for wear every 50-60 hours.

! CAUTION Using the tool with worn brushes will permanently

damage the motor.

Use only original Craftsman replacement brushes.

Inspect the rotary tool brushes after 40-50 hours of use. If the rotary tool runs erratically, loses power, or makes unusual noises check the brushes for wear and possible replacement. Remember: brushes in the rotary tool are similar to oil in a car; the more you check/service, the better the performance.

Follow these steps to check/change the rotary tool brushes.

1. With the power cord unplugged, place the tool on a clean surface. Use the tool wrench to pry up and release the clip on the brush cover (Figure A).

2. Remove the brushes from the tool by pulling the shunt and brass clip which are attached to the brush (Figure B).

NOTE: Be sure to note how the brass clip slides out of the slot next to the brush pocket. Also, note how the detent on brass clip fits into brush pocket slot, which secures the brass clip into proper position.

3. Check each brush for wear. If brush is less than 3/8" long, or if contact end is rough or pitted, replace the brush.
