Quick-clamping nuts (19) that are
properly secured and not damaged
can be removed by hand. To do this,
fold up the bar and turn the quick-
clamping nut firmly anticlockwise. If
the quick-clamping nut is stuck, do not
attempt to loosen it with a tool – al-
ways use a two-pin spanner.
After fitting the hub flange and the
grinding/cutting disc, the free thread
length of the grinding spindle must be
at least 4 mm.
Ensure that the abrasive tool is firmly
seated, so that it does not twist away
from the spindle in the runout of the power tool.
Mounting flange for grinding spindle M 14: A
plastic part (O-ring) is fitted around the cent-
ring collar in the mounting flange (13). If the
O-ring is missing or damaged, the mounting
flange (13) must be replaced before operation
can resume.
After fitting the abrasive tool, check that the abrasive
u
tool is fitted correctly and can turn freely before
switching on the power tool. Make sure that the abras-
ive tool does not brush against the protective guard or
other parts.
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)
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 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
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
