Quick-clamping nut
To change the abrasive tool easily without having to use any
additional tools, you can use the quick-clamping nut (18) in-
stead of the clamping nut (17).
The quick-clamping nut (18) may be used only for
u
grinding or cutting discs.
Only use quick-clamping nuts (18) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the
quick-clamping nut (18) is not facing the grinding disc;
the arrow must be pointing towards the index mark (31).
Press the spindle lock button (2) to
(31)
lock the grinding spindle. To tighten
the quick-clamping nut, turn the grind-
ing disc firmly clockwise.
If the quick-clamping nut has been at-
tached correctly and is not damaged,
you can loosen it by hand by turning
the knurled ring anticlockwise. If the
quick-clamping nut is stuck, do not
attempt to loosen it with pliers – al-
ways 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.
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.
