BRUSH INSPECTION
AND REPLACEMENT
CAUTION: BEFORE INSPECTING BRUSHES, DISCON-
NECT 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. 26, are located on the motor
housing opposite each other. Fig. 27, 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 service-
able after removing, reinstall them in the same position as
