cases, the power tool switches off and stays
switched off. The power tool can be started up
again by releasing the on/off switch (3) and press-
ing it again.
Working Advice
English
Pull the plug out of the socket before carry-
u
ing out any work on the power tool.
Exercise caution when cutting slots in struc-
u
tural walls; see the "Information on struc-
tural 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.
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 con-
siderably higher service life, lower noise levels and
lower sanding temperatures than conventional
sanding sheets.
Cutting Metal
English
Always use the protective guard for cutting
u
(13) when cutting with bonded abrasives.
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.
26 | English
The power tool must always
work in an up-grinding motion.
Otherwise there is a risk that it
will be pushed uncontrolled
out of the cut. For best results
when cutting profiles and rect-
angular tubing, start at the
smallest cross section.
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 (20), the dust extractor must be ap-
proved for extracting stone dust. Suitable dust ex-
tractors are available from Förch.
cially hard materials such as concrete with a high
pebble content, the diamond cutting disc can over-
heat 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 diamond
cutting disc to cool down by running the power tool
for a short time at maximum speed with no load.
Working noticeably slower and with circular spark-
ing indicate that the diamond cutting disc that has
become dull. You can resharpen the disc by briefly
cutting into 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 regu-
lations must be observed under all circumstances.
Seek advice from the responsible structural engin-
eer, architect or construction supervisor before
starting work.
Switch on the power
tool and position it with
the front part of the
guide block on the
workpiece. Move the
power tool with a mod-
erate feed motion that
is suited to the material
being machined.
