3.5. Replacing the motor brushes
Check
the
condition
of
the
carbon
brushes
every
100
work
hours.
To
do
this,
unplug the
machine from the power source, and unscrew the cover (
1
, Fig. 6). Next, unscrew the
pressing plate (
2
), and then remove the brush holder (
3
) and the brush (
4
). If the
length of the brush is less than 5 mm (3/16’’), replace both brushes with new ones.
To install brushes, proceed in reverse order. After the replacement, run the motor
without load for 20 minutes.
