Overload Protection
In order to protect the operator, motor and the tool, the concrete grinders
are equipped with a mechanical and thermal overload protection.
Thermal: In case of permanent overload, a thermal sensor protects
the motor against destruction. In this case, the tool
switches off automatically and can only be restarted after a
certain cooling period (approx. 2 minutes). Actuate the
ON/OFF switch! The cooling period depends on the
heating of the motor winding and the ambient temperature.
Care and Maintenance
Before the beginning of the 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 power tool needs a minimum of care and
maintenance. The following works have to be carried out or rather the
component parts have to be inspected:
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.
Environmental Protection
Raw Material Recycling Instead of Waste Disposal
To avoid damages on transportation, the power tool has to be delivered in
a sturdy packing. Packaging as well as unit and accessories are made of
recyclable materials and can be disposed accordingly.
