Motor Brushes

time. To remove, unscrew
the brush cap located on
the side of the housing, tip
the hole downward and let
the brush and spring fall
out.

sets (2 brushes and 2
springs) to insure equal

technician who is familiar

Department for interior
cleaning, dressing of the
commutator, or whatever
maintenance is required.
