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.

If the quick-clamping nut
has been attached correctly
and is not damaged, you
can loosen it by hand by
turning the knurled ring an-
ticlockwise. If the quick-
clamping nut is stuck, do
not attempt to loosen it
with pliers – always use
the two-pin spanner. Posi-
tion the two‑pin spanner as
shown in the figure.

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 figures F and G)
Slide off the dust filter (4) at the bottom of the power tool in
the direction of the arrow.
Do not hold the dust filter (4) 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.
