Approved abrasive tools
You can use all the abrasive tools mentioned in these operat-
ing instructions.
-1
The permissible speed [min ] or the circumferential speed
[m/s] of the abrasive tools used must at least match the val-
ues given in the table.
It is therefore important to observe the permissible rota-
tional/circumferential speed on the label of the abrasive
tool.

Rotating the machine head (see figure E)
Pull the plug out of the socket before carrying out any
u
work on the power tool.
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).
Removing the Dust Filter (see figure F)
Slide off the dust filter (5) at the bottom of the power tool in
the direction of the arrow.
Do not hold the dust filter (5) by its sides and do not pull it
off.

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.
Pull the plug out of the socket before carrying out any
u
work on the power tool.
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
Always use the protective guard for grinding (9) when
u
rough grinding with bonded abrasives.
Never use cutting discs for rough grinding.
u
When rough grinding, the protective guard for
u
cutting (11) or the protective guard for grinding (9)
with a fitted cover for cutting (13) 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 (11) or the protective
u
guard for grinding (9) with a fitted cover for cutting (13)
must be used when using bonded discs which are ap-
proved for cutting and grinding.
