justments, cleaning, performing maintenance, or

should be periodically checked for wear.
Follow these steps to replace the brushes:
Unplug the drill.
Remove the brush cap with a flat blade screwdriver. The
brush assembly is spring loaded and will pop out when
you remove the brush cap.
Remove the brush assembly (brush and spring).
Check for wear. If worn, always replace in pairs.
Do not replace one side without replacing the other.
