English | 25
The regulations on the material being machined that apply in
the country of use must be observed.
u
Avoid dust accumulation at the workplace. Dust can
easily ignite.
Operation
u
Do not load the power tool so heavily that it comes to a
stop.
u
Pull the plug out of the socket before carrying out any
work on the power tool.
u
Exercise caution when cutting slots in structural walls;
see the "Information on structural design" section.
u
Clamp the workpiece if it is not secure under its own
weight.
u
If the power tool has been subjected to a heavy load,
continue to run it at no-load for several minutes to
cool down the accessory.
u
Do not use the power tool with a cut-off stand.
u
Do not touch grinding and cutting discs until they have
cooled down.
The discs can become very hot while work-
ing.
Working advice
Rough grinding
u
Always use the protective guard for grinding (8) when
rough grinding with bonded abrasives.
u
Never use cutting discs for rough grinding.
u
When rough grinding, the protective guard for
cutting
(10) or the protective guard for grinding (8)
with a fitted cover for cutting (11) can impact the
workpiece and lead to a loss of control.
The best rough grinding results are achieved with a set angle
of 30° to 40°. Move the power tool back and forth with mod-
erate pressure. This will ensure that the workpiece does not
become too hot or discolour and that grooves are not
formed.
u
The protective guard for cutting (10) or the protective
guard for grinding (8) with a fitted cover for cutting (11)
must be used when using bonded discs which are ap-
proved for cutting and grinding.
Surface grinding with flap disc
u
Always use the protective guard for grinding (8) when
grinding with the flap disc.
The flap disc (accessory) enables you to machine curved
surfaces and profiles. Flap discs have a considerably longer
service life, lower noise levels and lower grinding temperat-
ures than conventional grinding discs.
Surface grinding with sanding disc
u
Always fit the hand guard (23) when working with the
rubber sanding pad (24) .
Grinding with a sanding disc can be done without a protect-
ive guard.
See the graphics page for fitting instructions.
Screw on the round nut (26) and tighten with the combina-
tion wrench .
Cup brush/disc brush/conical brush
u
Always use the protective guard for grinding (8) when
brushing with disc brushes. Brushing with cup
brushes/conical brushes can be performed without
the protective guard.
u
Always fit the hand guard (23) when working with the
cup brush or conical brush.
u
The wires of the disc brush can get caught on the pro-
tective guard and break, if the maximum permitted di-
mensions of the disc brushes are exceeded.
See the graphics page for fitting instructions.
The cup brush/conical brush/disc brush with M14 thread
must be screwed onto the grinding spindle until it rests
firmly against the grinding spindle flange at the end of the
grinding spindle thread. Tighten the cup brush/conical
brush/disc brush with an open-ended spanner.
To fasten the disc brush with a diameter of 22.22 mm, at-
tach the mounting flange with O-ring
(12) to the grinding
spindle (22) , screw on the round nut (26) and tighten with
the combination wrench.
Cutting Metal
u
For cutting metal with bonded cutting discs or dia-
mond cutting discs, always use the protective guard
for cutting
(10) or the protective guard for
grinding (8) with a fitted cover for cutting (11).
u
When using the protective guard for grinding (8) for
cutting work with bonded cutting discs, there is an in-
creased risk of being exposed to sparks, particles and
disc fragments if the disc breaks.
When carrying out abrasive cutting, use a moderate feed
that is suited to the material being machined. 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.
The power tool must always work in an
up-grinding motion. Otherwise there
is a risk that it will be pushed
uncon-
trolled out of the cut. For best results
when cutting profiles and rectangular
tubing, start at the smallest cross sec-
tion.
Cutting stone
u
For cutting stone with bonded cutting discs or dia-
mond cutting discs for stone/concrete, always use the
protective guard for cutting
(10) or the protective
guard for grinding (8) with a fitted cover for
cutting (11) .
u
Provide sufficient dust extraction when cutting stone.
u
Wear a dust mask.
u
The power tool may be used only for dry cutting/grind-
ing.
