Cleaning, Maintenance, and Lubrication
1. BEFORE EACH USE, inspect the general
condition of the tool. Check for:
• loose hardware,
• misalignment or binding of moving parts,
• cracked or broken parts,
• damaged electrical wiring, and
• any other condition that may
affect its safe operation.

of the tool with clean cloth.
3. WARNING! If the supply cord of this
power tool is damaged, it must be replaced
only by a qualified service technician.
4. CARBON BRUSH MAINTENANCE.
The carbon brushes 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 overtighten.
Note: New carbon brushes tend to spark when first used New carbon brushes tend to spark when first used
until they wear and conform to the motor’s armature.
