The carbon brushes may require
maintenance when the motor perfor-
mance of the tool decreases or stops
working completely. To maintain the
brushes:
a. Remove the Carbon Brush Cover
(72, 110) on each side of the motor
housing.
b. Remove the carbon brushes from
the housing. Keep track of which
orientation the old carbon brush-
es were in to prevent needless
wear if they will be reinstalled.
c. If either carbon brush is worn down
by more than 1/2, replace them both.
d. To clean old carbon brushes before
reusing them, rub the contact areas
with a pencil eraser.
e. Reinsert the old carbon brushes in
the same orientation to reduce wear.
f. When installing, make sure the car-
bon portions of the brushes contact
the motor armature, and that the
springs face away from the motor.
Also, make sure the springs operate
freely.
g. Replace the Carbon Brush Covers.
Do not overtighten.
note: New carbon brushes tend to spark
when first used until they wear and
conform to the motor's armature
WarnInG! If the supply cord of
this power tool is damaged, it must
