KEEP TOOL CLEAN

NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.
Wear ANSI Z87.1 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 in the outlet.
Also, check for blown fuses or open circuit breakers in the line.
LUBRICATION
This tool has been lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal
operating conditions. No further lubrication is necessary.

BRUSH INSPECTION AND REPLACEMENT

BEFORE INSPECTING OR REMOVING 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. 46 are located on the motor housing opposite each other. Fig. 47 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.
