Check the condition of the carbon brushes every 100 operational hours. If the length
of
the
brushes
is
less
than
5
mm
(0.2’’),
replace
them
with
new
ones.
To
do
this,
unplug
the
power
cord
from
the
power outlet, unscrew
four screws mounting the motor cover
and gently remove the cover (Figure 10). Proceed with caution paying attention to the
grounding wire connected to the cover. Then, press the center of the
brush
wire
connector
to
unlock it and
remove the connector.
Unbend the spring, put it on the top
of the brush holder, and gently remove the brush. Proceed as described also for the
second brush located at the opposite side of the motor. To mount brushes, proceed
in reverse order. After the replacement, run the motor without load for 20 minutes.
