Brush Inspection And Replacement - Black & Decker BDMS100 Instruction Manual

BRUSH INSPECTION AND REPLACEMENT

Brush life varies. It depends on the load on the motor. Check the brushes after the first 50 hours of use for a new machine or after
a new set of brushes has been installed. After the first check, examine them after about 10 hours of use until a replacement is
necessary. To inspect the brushes:
DISCONNECT MACHINE FROM POWER SOURCE!
1. Remove three screws (A) Fig. 44 and remove the motor
cover (B).
2. The brushes are located in the two holders (C) Fig. 45.
Remove spade type terminal connector (D) and pull out
brush holders (C).
3. Fig. 46 illustrates one of the brushes (E) removed from the
holder (C). When the carbon on either brush (E) is worn to
3/16" in length or if either spring (F) or shunt wire is
burned or damaged in any way, replace both brushes. If
the brushes are found to be serviceable after re-moving,
reinstall them in the same position.

liquid.
