Brush Replacement

This mill/drill is equipped with a universal motor that uses two carbon brushes to transmit elec- trical current inside the motor. These brushes are considered to be regular "wear items" or "consumables" that will need to be replaced dur- ing the life of the motor. The frequency of required replacement is often related to how much the motor is used and how hard it is pushed.

Replace the carbon brushes (part number: P0758202) when the motor no longer reach- es full power, or when the brushes measure less than 1⁄4" long (new brushes are 5⁄8" long).
