Servicing

Procedures not specifically explained in this manual must be performed only by a qualified technician.

To prevent serious injury

from accidental operation:

Turn the Power Switch of the tool to its “OFF” position and unplug the tool from its electrical outlet before performing any inspection, maintenance, or cleaning procedures.

To prevent serious injury from tool failure:

Do not use damaged equipment. If abnormal noise or vibration occurs, have the problem corrected before further use.

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.Periodically blow dust and grit out of the motor vents using dry com- pressed air. Always wear safety glasses when performing this mainte- nance operation.

3.After Use, clean external surfaces of the tool with clean cloth. Never use solvents or harsh cleaners as they may damage the housing. To pre- vent electrical shock, do not allow water or other liquids to enter the motor vent holes.

4.Carbon Brush (46) Mainte- nance.

The carbon brushes may require maintenance when the motor perfor- mance of the tool decreases or stops working completely. To maintain the brushes:

a.Unscrew the Brush Cap (45) using a flat head screwdriver (sold sepa- rately).

b.Pull Brush from the Plastic Housing (35). Keep track of which orienta- tion 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 both car- bon brushes.

d.To clean old carbon brushes before reusing them, rub the contact areas with a pencil eraser.

e.Hold the spring clips to the side and 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 mo- tor armature, and that the indented portions of the brushes are posi- tioned where the springs contact. Also, make sure the springs operate freely.

g.Reconnect the Carbon Brush Leads.

h.Replace the Brush Caps. Do not overtighten.
