Rotating the machine head (see figure A)
Before carrying out any work on the power tool (e.g.
u
maintenance, tool change etc.), remove the battery
from the power tool. There is risk of injury from uninten-
tionally pressing the on/off switch.
The machine head can be rotated in 90° increments. In this
way, the on/off switch can be brought into a more favourable
handling position for particular applications, e.g. for left-
handed tool users.
Completely unscrew the four screws (➊). Rotate the ma-
chine head carefully, without removing it from the hous-
ing, into the new position (➋). Screw in and retighten the
four screws (➌).
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.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
Do not load the power tool so heavily that it comes to a
u
stop.
Before carrying out any work on the power tool (e.g.
u
maintenance, tool change etc.), remove the battery
from the power tool. There is risk of injury from uninten-
tionally pressing the on/off switch.

Exercise caution when cutting slots in structural walls;
u
see the "Information on structural design" section.
Clamp the workpiece if it is not secure under its own
u
weight.
If the power tool has been subjected to a heavy load,
u
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 stand.
u
Do not touch grinding and cutting discs until they have
u
cooled down. The discs can become very hot while work-
ing.
Working advice
Rough grinding
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 mod-
erate pressure. This will ensure that the workpiece does not
become too hot or discolour and that grooves are not
formed.
Surface grinding with flap disc
Always use the protective guard for grinding (10)
u
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
Always fit the hand guard (23) when working with the
u
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 it with the two-pin
spanner.
Cup brush/disc brush/conical brush
Always use the protective guard for grinding (10)
u
when brushing with disc brushes (15). Brushing with
cup brushes (27)/conical brushes (28) can be per-
formed without the protective guard.
Always fit the hand guard (23) when working with the
u
cup brush or conical brush.
The wires of the disc brush can get caught on the pro-
u
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.
