CARBON BRUSH MAINTENANCE.3.
The carbon brushes may require
maintenance when the motor perfor-
mance of the tool decreases or stops
working completely. To maintain the
brushes:
Remove the brush cap (14) on each a.
side of the motor housing.
Remove the carbon brushes (12) b.
from the housing. Keep track of
which orientation the old carbon
brushes were in to prevent need-
less wear if they will be rein-
stalled.
If either carbon brush is worn down c.
by more than 1/2, replace both car-
bon brushes.
To clean old carbon brushes before d.
reusing them, rub the contact areas
with a pencil eraser.
Reinsert the old carbon brushes in e.
the same orientation to reduce wear.
When installing the carbon brushes, f.
make sure the carbon portions of the
carbon brushes contact the motor
armature, and that the springs face
away from the motor. Also, make
sure the springs operate freely.
Replace the brush caps. Do not g.
overtighten.
Note: New carbon brushes tend to spark
conform to the motor’s armature.
