MAINTENANCE
To maintain product SAFETY and RELIABILITY, repairs, any other maintenance
or adjustment should be performed by your nearest authorized service center. All
the ball bearings are sealed and lubricated for life and will require no
maintenance.
Cleaning
• After use, wipe off chips and dust adhering to the tool with a cloth or the like.
• Keep the blade guard clean.
BRUSH INSPECTION AND REPLACEMENT
CAUTION: BEFORE INSPECTING THE 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 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 are located on the motor housing opposite each other. Fig.21
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.
To remove brush, undo brush cap (A) Fig.21 with flat head screwdriver. Remove
carbon brush (B) from brush holder (C). If the brushes are found serviceable
after removing, reinstall them in the same position as removed. If a brush needs
replacement, replace both brushes.
