For cutting especially hard material, e. g.,
concrete with high gravel content, the dia-
mond cutting disc can overheat and be-
come damaged as a result. This is indi-
cated clearly by a ring of sparks that rotates
with the diamond cutting disc.
In this case, interrupt the cutting process and al-
low the diamond cutting disc to cool by running
frely at no-load speed for a short time.
Noticeable decreasing work progress and a rotat-
ing spark ring are indications of a diamond cutting
disc that has become dull. With brief cuts in an
abrasive material (e. g., chalky sand stone), it
can be sharpened again.

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and the ventilation slots clean.
After finishing work, disassemble the diamond
cutting discs and clean the clamping parts and
the protective cover.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an authorized after-sales
service agent 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 con-
necting a new 3-pin plug to the 2 wire cable.
The wires in the cable are coloured according to
the following code:
strain relief
live = brown
neutral = blue
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 machine it must be
disposed of safely.

Service Indicator 9

chine switches itself off. This is indicated approx.
eight hours beforehand by the lighting or blinking
of the service indicator 9. The machine must then
be sent to customer service for maintenance (for
addresses, see Section "Service and Customer
Assistance").
