To switch off the power tool, release the on/off
switch (5); or, if the switch is locked, briefly push
the on/off switch (5) backward and down and
then release it.
Always check abrasive tools before using
u
them. The abrasive tool must be fitted prop-
erly and be able to move freely. Carry out a
test run for at least one minute with no load.
Do not use abrasive tools that are damaged,
run untrue or vibrate during use. Damaged ab-
rasive tools can burst apart and cause injuries.
Restart protection
English
The restart protection feature prevents the power
tool from uncontrolled starting after the power
supply to it has been interrupted.
To restart the tool, set the on/off switch (5) to the
off position and then switch the power tool on
again.
Working Advice
English
Exercise caution when cutting slots in struc-
u
tural walls; see the "Information on structural
design" section.
Clamp the workpiece if it is not secure under
u
its own weight.
Do not load the power tool so heavily that it
u
comes to a stop.
If the power tool has been subjected to a
u
heavy load, continue to run it at no-load for
several minutes to cool down the accessory.
Do not use the power tool with a cut-off
u
stand.
If the power tool becomes electrostatically
charged, the built-in electronics will switch the
power tool off. Press the on/off switch (5) again to
restart the power tool.
Do not touch grinding and cutting discs until
u
they have cooled down. The discs can be-
come very hot while working.
Rough grinding
English
Never use cutting discs for rough grinding.
u
The best rough grinding results are achieved with
a set angle of 30° to 40°. Move the power tool
back and forth with moderate pressure. This will
ensure that the workpiece does not become too
hot or discolour and that grooves are not formed.
Flap Disc
English
With the flap disc (accessory), curved surfaces
and profiles can be worked. Flap discs have a
considerably higher service life, lower noise levels
and lower sanding temperatures than conven-
tional sanding sheets.
Cutting Metal
English
Always use the protective guard for cutting
u
(11) when cutting bonded abrasives.
24 | English
When carrying out abrasive cutting, use a moder-
ate feed that is suited to the material being ma-
chined. Do not exert pressure on the cutting disc
and do not tilt or swing the power tool.
Do not attempt to reduce the speed of a cutting
disc coming to a stop by applying pressure from
the side.
Cutting stone
English
Provide sufficient dust extraction when cut-
u
ting stone.
Wear a dust mask.
u
The power tool may be used only for dry cut-
u
ting/grinding.
For best results when cutting stone, use a dia-
mond cutting disc.
When using the extraction guard for cutting with a
cutting guide (21), the vacuum cleaner must be
approved for vacuuming stone dust. Suitable va-
cuum cleaners are available from Berner.
larly hard materials such as concrete with a high
pebble content, the diamond cutting disc can
overheat and become damaged as a result. This
is clearly indicated by circular sparking, rotating
with the diamond cutting disc.
If this happens, stop cutting and allow the dia-
mond cutting disc to cool down by running the
power tool for a short time at maximum speed
with no load.
If work is noticeably slower and there is circular
sparking, this indicates that the diamond cutting
disc has become blunt. You can resharpen the
disc by making short cuts in an abrasive material
(e.g. lime-sand brick).
Information on structural design
Slots in load-bearing walls are subject to DIN
1053 part 1 or country-specific regulations. These
The power tool must
always work in an up-
grinding motion. Other-
wise, there is a risk
that it will be pushed
uncontrolled out of
the cut. For best res-
ults when cutting pro-
files and rectangular
tubing, start at the
smallest cross section.
Switch on the power
tool and position it with
the front part of the
cutting guide on the
workpiece. Move the
power tool with a mod-
erate feed motion that
appropriate to the ma-
terial being machined.
