Overload protection
In order to protect the operator, motor and tool, the wall chaser is equipped with an electronic and thermal
overload protection.
Electronic:
To warn the user against an overload of the machine due to too high contact pressure, a LED is attached to
the switch grip. It does not light during idle run or at normal load. When the unit is overloaded the LED light is
red, in this case, the unit must be stress-relieved. You can continue working after having stress-relieved and
switching OFF and ON the power tool again.
Thermal:
In case of permanent overload, a thermocouple 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). The cooling period depends on the heating of the motor winding and the
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.
•
Customer service will answer your questions about repair and maintenance of your product as well as spare
parts.
