AND REPLACEMENT
DISCONNECT MACHINE FROM 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 have been installed.
After the first check, examine the brushes after about 10 hours of use until such time that replacement is necessary.
The brush holders (A) Fig. 24, are located on the motor housing opposite each other. Fig. 25 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 servicable after removing, reinstall them in the same position as removed.
