Cleaning, Maintenance, and
Lubrication
1.BEFORE EACH USE, inspect the general condition of the tool. Check for loose screws, misalignment or binding of moving parts, cracked or broken parts, damaged electrical wir- ing, and any other condition that may affect its safe operation.
2.After Use, clean external surfaces of the tool with clean cloth.
3.Carbon Brush Maintenance.
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 brush cap (14) on each side of the motor housing.
b. Remove the carbon brushes (12) 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.
c. If either carbon brush is worn down by more than 1/2, replace both car- bon brushes.
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 the carbon brushes, 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.
g.Replace the brush caps. Do not overtighten.
Note: New carbon brushes tend to spark when first used until they wear and conform to the motor’s armature.
