BRUSH INSPECTION AND REPLACEMENT
CAUTION: BEFORE INSPECTING BRUSHES, DISCONNECT THE MACHINE FROM THE POWER
SOURCE.
Brush life varies. It depends on the load on the motor. Check the brushes after the first 100 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. 54, are located on the motor housing opposite each other. Fig. 55, illustrates one of
the brushes removed for inspection. When the carbon on either brush (B) is worn to
3
…16" in length or if either
spring or shunt wire (C) is burned or damaged in any way, replace both brushes. If the brushes are found
serviceable after removing, reinst all them in the same position as removed.
