BRUSH INSPECTION AND REPLACEMENT
CAUTION: BEFORE INSPECTING BRUSHES, DISCONNECT THE MACHINE FROM THE POWER SOURCE.
Brush life varies, depends on the load on the motor. Check the brushes after the first 50 hours of use of 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 replacement is necessary.
The brush holders (A) Fig. 49, are located on the motor housing opposite each other. Fig. 50, 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, reinstall them in the same position.
KEEP TOOL CLEAN
Periodically blow out all air passages with dry compressed air. Clean all plastic parts with a soft damp cloth.
NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.
CAUTION: WEAR SAFETY GLASSES WHILE USING COMPRESSED AIR.
FAILURE TO START
Should your tool fail to start, check to make sure the prongs on the cord plug are making good contact with the
outlet. Also, check for blown fuses or open circuit breakers in the line.
