BRUSH INSPECTION

AND REPLACEMENT

CAUTION: BEFORE INSPECTING BRUSHES, DIS-

CONNECT THE MACHINE FROM THE POWER

SOURCE.

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 such time that replacement is necessary.

The brush holders (A) Fig. 44, are located on the motor

housing opposite each other. Fig. 45, illustrates one of

the brushes removed for inspection. When the carbon on

either brush is worn to 3/16" in length or if either spring or

shunt wire is burned or damaged in any way, replace both

brushes. If the brushes are found serviceable after

removing, reinstall them in the same position as

removed.
