CLEANING, MAINTENANCE, &
LUBRICATION
1. Before each use, inspect the
general condition of the tool. Check
for:
parts
its safe operation
2. After use, wipe external surfaces
of the tool with a clean cloth.
3. Periodically blow dust and grit out
of the motor vents using dry
compressed air. Wear ANSI-
approved safety goggles and
NIOSH-approved breathing
protection while doing this.
4. Periodically recheck all nuts,
bolts, and screws for tightness.
5. Remove foam pad from backing
pad when polisher is not in use.
This will allow backing pad to dry
and retain its original shape. Wash
with mild soap and water before
storing.
6. The polishing bonnet may be
machine washed in cold water with
mild detergent.
Do not put in the
dryer.
7. Use only a clean cloth and mild
detergent to clean the body of the
polisher. Do not use solvents. Do
not immerse any part of the tool in
liquid.
8. Carbon Brush Maintenance. The
carbon brush may require
maintenance when the motor
performance of the tool decreases
or stops working completely. To
maintain the brushes:
a. Remove the carbon brush cover
on each side of the motor housing.
b. Remove the carbon brushes
from the housing. Keep track of
which orientation the old carbon
brushes 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
carbon 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 over-tighten.
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
