3.11. Replacing the motor brushes
Check
the
condition
of
the
carbon
brushes
every
100
operation
hours.
To
do this, unplug
the machine from the power source, use the 4 mm hex wrench to unscrew four
screws
(
1
,
Fig.
12),
and then
remove
the motor cover (
2
), paying attention to the ground wire
3
attached. Next, pry off the spring that holds the brush and rest the spring on the top
of the brush holder (
4
). Unlock the connector by pressing it in the center (
5
), and then
remove the connector (
6
) and the brush (
7
). If the length of the brush is less than
5 mm (0.2’’), replace both brushes with new ones.
To install brushes, proceed in reverse order. After the replacement, run the motor
without load for 20 minutes.
