Rotating the machine head (see figure E)
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally 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 4 screws (➊). Rotate the machine
head carefully, without removing it from the housing, into
the new position (➋). Screw in and retighten the 4
screws (➌).
Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
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.

Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally 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.
If the power tool becomes electrostatically charged, the
built-in electronics will switch the power tool off. Press the
on/off switch (4) again to restart the power tool.
Working advice
Rough grinding
Always use the protective guard for grinding (12)
u
when rough grinding with bonded abrasives.
Never use cutting discs for rough grinding.
u
When rough grinding, the protective guard for
u
cutting (13) or the protective guard for grinding (12)
with a fitted cover for cutting (14) 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.
The protective guard for cutting (13) or the protective
u
guard for grinding (12) with a fitted cover for cutting (14)
must be used when using bonded discs which are ap-
proved for cutting and grinding.
Surface grinding with flap disc
Always use the protective guard for grinding (12)
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 (27) when working with the
u
rubber sanding pad (28).
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 (30) and tighten it with the two-pin
spanner.
