Maintenance and Service
Maintenance and Cleaning
f Before any work on the machine itself, pull
the mains plug.
f For safe and proper working, always keep
the machine and ventilation slots clean.
f A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales service.
Service Indicator 7
When the carbon brushes are worn out, the machine
switches itself off. This is indicated approx. 8 hours
beforehand by the lighting or blinking of the service
indicator 7. The machine must then be sent to an after-
sales service agent.
Stand-by Indicator 8
When the mains plug is plugged in and mains voltage
is given, the stand-by indicator 8 must be lit. When the
machine cannot be switched on despite lit stand-by
indicator 8, it must be sent to an after-sales service
agent.
If the machine should fail despite the care taken in
manufacturing and testing procedures, repair should
be carried out by an after-sales service centre for
Berner power tools.
In all correspondence and spare parts orders, please
always include the 6-digit order number given on the
nameplate of the machine.
WARNING! Important instructions for connect-
ing a new 3-pin plug to the 2-wire cable.
The wires in the cable are coloured according to the
following code:
Do not connect the blue or brown wire to the earth
terminal of the plug.
Important: If for any reason the moulded plug is
removed from the cable of this power tool, it must be
disposed of safely.
Disposal

sorted for environmental-friendly recycling.

2002/96/EC for Waste Electrical and
Electronic Equipment and its imple-
mentation into national right, power

arately and disposed of in an environmentally correct
manner.
