CHECK AND REPLACEMENT OF CARBON
BRUSHES
WARNING: Before checking the carbon brushes,
disconnect the machine from the power supply.
The life of the carbon brushes can vary, and it depends on the
motor working load. If the tool is new or after the replacement
of the carbon brushes, check the carbon brushes after the
fi rst 50 hours of use. After the fi rst check, you must control
the carbon brushes every 10 hours of use until it is necessary
to replace them.
The housing of the carbon brushes
(Fig. 19)
are positioned
on each side of the motor. Change both the carbon brushes
if the carbon of one of the brushes is worn and it is smaller
than 5 mm, or in case a spring or a wire is burnt or damaged.
If the carbon brushes are still usable after the inspection,
re-assemble them on their original position.
