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 such time that replacement is necessary.
The brush holders (A) Fig. 41 are located on the motor housing opposite each other. Fig. 42 illustrates one of the brush-
es removed for inspection. When the carbon on either brush (A) Fig. 42 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 remov-
ing, reinstall them in the same position as removed.
