BRUSHES
AND
COMMUTATOR
Failure
of
the
motor
to
start
or
to
operate
efficiently
is
usually
caused
by
worn
or
damaged
brushes,
brushes
that
stick
in
the
holders
and
fail
to
make
proper
contact
with
the
commutator,
or a
dirty
or
rough
commutator.
Occasional
inspection
of
brushes
and
commutator
is
recommended
To
inspect
the
brushes,
remove
plug
from
power
source.
Unscrew
brush
retainer
caps
located
on
the
motor
housing.
Pull
out
brush
retainer
springs
and
brushes.
Replace
brushes
when

3/16". Always
replace
both
brushes
at
the
same
time.
When
inspecting
brushes,
also

the
commutator
for
wear.

under-
cutting
and
dressing
of
the
commutator.
