Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
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(6) when
rough grinding with bonded abrasives.
u Never use cutting discs for rough grinding.
u When rough grinding, the protective guard for
cutting(5) or the protective guard for grinding(6)
with a fitted cover for cutting(7) can impact the work-
piece 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(5) or the protective
guard for grinding(6) with a fitted cover for cutting(7)
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(6) 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 (16) when working with the
rubber sanding pad (17).
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(19) and tighten it with the two-pin
spanner.
Cup brush
u Brushing with cup brushes can be performed without
the protective guard.
u Always fit the hand guard (16) when working with
the cup brush.
See the graphics page for fitting instructions.
The cup 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 with an open-ended spanner.
Cutting Metal
u For cutting metal with bonded cutting discs or dia-
mond cutting discs, always use the protective guard
for cutting(5) or the protective guard for grinding(6)
with a fitted cover for cutting(7).
u When using the protective guard for grinding(6) 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.
