Electrical:
In case of overload due to too large feed force, the
electronic will cut OFF the machine. After discharge and
switching ON you can continue drilling again.
Thermal:
In case of permanent overload, a thermocouple protects the
motor against destruction. In that case, the tool switches off
and can only be restarted after a certain cooling-down
period (approx. 2 minutes). The cooling-down time depends
on the temperature of the motor winding and ambient
temperature.
Safety Clutch
The slip clutch served for compensation of shocks and overload. To keep
its functionability, it should not slip for more than 2 seconds. In case of
excessive wearing, it can be replaced by an authorized service centre.
Care and Maintenance
Before the beginning of the maintenance- or repair works you
have to disconnect plug from the mains.
It is a must to unplug the tool before starting any service or repair works.
Repairs may be executed only by appropriately qualified and experienced
personnel.
After every repair, the unit has to be checked by an electrical specialist.
According to its design, the tool requires a minimum of care and
maintenance. However, the following maintenance works and component
checks have to be performed in regular intervals:
Clean the tool after completion of your work. Apply some grease onto
the drilling spindle thread. The ventilation slots must always be clean
and unclogged. Make sure that now water gets into the tool during
cleaning.
After approx. 250 hours of operation, the carbon brushes must be
checked and, if necessary, be replaced by an authorized specialist (use
only original carbon brushes).
Once per quarter of a year, an electrical specialist should check the
switch, cable and plug.
Environmental Protection
Raw material recycling instead of waste disposal
To avoid damages in transit, the tool is supplied in a sturdy packing. The
packing as well as the tool and its accessories are made of recyclable
