REPLACING CARBON MOTOR BRUSHES
The carbon motor brushes will wear down and
require replacing. The time intervals between
replacements will vary depending upon the
working environment and the hours of use. It is
recommended that the brushes be checked
after each 10 hours of use. When the length of
the carbon brush reaches 1/4" (6.35 mm), the
brushes should be replaced.
WARNING: Unplug the tool from the
power source.
1. Use a 3/16" (5 mm) slot screwdriver and
remove one brush cap (1) (fig. 13). Turn
the brush cap counter-clockwise to remove
it from the motor housing.
2. Pull the spring & brush assembly (2) from
the brush holder (3) in the motor housing
(4).
3. Insert the new spring & brush assembly
into the motor housing.
4. Compress the spring into the brush holder
and thread the brush cap back into the
motor housing.
NOTE: Make sure the brush cap threads
are not cross-threaded. Do NOT over
tighten.
5. Repeat steps 1 to 4 to replace the second
carbon brush located on the opposite side
of the motor housing.
