Bosch Tool is the manufacturer of a number of power tools, including saws, sanders, drills and much more. Bosch offers a variety of random orbital sanders, in both a palm-style grip, or with an elongated body for two-handed operation. In either case, the motor employs an armature that utilises a pair of brushes that can wear out over time. Replacing the brushes on a Bosch DVS random orbital sander requires only a bit of time and a couple of screwdrivers.
Disconnect the power cord from the electrical socket.
Loosen the screw at the top of the sander with a Torx screwdriver and lift off the cap.
Locate the two brushes on either side of the armature. Gently bend back the spring holding one of the brushes against the armature with a flathead screwdriver and pull out the brush.
Pull the wire connecting the brush to the motor off the spade connector and install the wire of a new brush onto the spade connector.
Insert the new brush into the brush housing and release the screwdriver, allowing the spring to hold the new brush in place.
Repeat steps 3 to 5 for the other brush.
Replace the cap onto the top of the motor housing and secure it by tightening the Torx screw.
Connect the power plug to the outlet and test the motor.
