indication, the electronics will independently switch the tool off.
After relieving be switching the tool off and on, the work can be
continued as normal.
Thermal: In case of permanent overload, a thermocouple protects the
motor against destruction. Here also, the user is warned by the
overload indicator. Shortly before the maximum temperature is
reached, the indicator flashes red.
In that case, the tool switches off and can only be restarted
after a certain cooling-down period (approx. 2 minutes). The
overload indicator flashes until the machine has cooled
sufficiently and can be used again. The cooling-down time
depends on the temperature of the motor winding and ambient
temperature.
Care and Maintenance
Before the beginning of maintenance or repair works you
have to disconnect the plug from the mains.
Repairs may be executed only by appropriately qualified and experienced
personnel. After every repair the machine has to be inspected by an electric
specialist.
Due to its design, the machine needs a minimum of care and maintenance.
However, the following points always have to be observed:
Always keep the power tool and the ventilation slots clean.

During work, please pay attention that no particles get inside the

machine.
In case of failure, a repair has to be carried out by an authorised service

workshop.
Auto-stop brushes
In order to protect the motor, this power tool is equipped with auto-stop brushes.
When the carbon brushes are worn out, the machine switches itself off. In this
case both brushes must be replaced at the same time with original brushes by
an electrical specialist.
In addition there is a service indicator (I) on the operating
handle which indicates in advance that the machine is
about to shut down due to worn carbon brushes. After the
indicator lights up, you can use the tool for approximately 1
day. Then the carbon brushes should be replaced.
