Motor Brushes
1) Unplug tool before remov-
ing brushes.

(at least every 100 hours of
running time). If brushes
are less than 1/8" long,

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 ten-
sion. If returning partially
used brushes, match the
curvature of the brushes to
the commutator.

in hole, drop in new spring
and screw on brush cap.

are worn down, return the
tool to a qualified repair
technician who is familiar
with the repair of electric
tools, a qualified service
organization or Master
Appliance Corp.'s Repair
Department for interior
cleaning, dressing of the
commutator, or whatever
maintenance is required.

Appliance Corp. replace-
ment parts.

ther lubrication.

ing. To clean outside of tool,
