4.To clean or replace the Carbon Brushes (38): It may become necessary to clean or replace the two Carbon Brushes when the Motor performance de- creases, or stops working completely. The Carbon Brushes are located on each side of the Motor Housing (40). To do so, remove the two Brush Holder Covers (37). Then, remove the two Carbon Brushes from the Brush Holders

(39). If the Carbon Brushes are worn down more than 1/2, replace both Carbon Brushes. If, however, the Carbon Brushes are just dirty they may be cleaned by rubbing them with a pencil eraser; if only cleaning is required, clean and place brushes in the same position as they were orginally in. When installing the Car bon Brushes, make sure the carbon portion of the Carbon Brushes contact the Motor Armature (30), and the springs face away from the Motor. Also, make sure the springs operate freely. After cleaning or replacement, replace the Brush Holder Covers.

NOTE: New Carbon Brushes tend to arc or spark when first used until they wear and conform to the Motor’s Armature.

(See Assy. Diagram.)

5.To clean the exterior parts of the Angle Grinder, use only a clean cloth and mild detergent. Then dry. Do not immerse any electrical part of the tool in any liquids.

6.Make sure to store the Angle Grinder in a clean, dry, safe location out of reach of children and other unauthorized people.

7. CAUTION! All maintenance, service, or repairs not mentioned in this manual must only be performed by a qualified service technician.
