Replacing Carbon Brushes
Remove and check the carbon brushes regularly (normally after 50 hours of use). The carbon brushes are
installed inside the motor housing. Using a screwdriver, remove the 2 pan head screws (B) Fig.26 that hold the
motor housing cap (A) in place.
Once the motor housing cap is removed, to release the carbon brush (B) Fig.27 from the holder, lower the
retaining spring (A). Disconnect the carbon brush wire (C) from the terminal, remove the carbon brush from the
Fig.26
motor housing and inspect it. Repeat this step for the second carbon brush.
Carbon brushes need to be replaced once they wear down to the limit mark, see Fig.28. Keep the carbon
brushes clean and free to slip in the holders. If they have worn down to the limit mark, purchase a set of identi-
cal replacement carbon brushes (both carbon brushes should be replaced at the same
time). Insert new carbon brushes into the holders, connect them to the terminals, reposition the retaining spring
and reinstall the motor housing cap using the 2 pan head screws.
