Always secure a grinding/cutting disc using only the
u
quick-clamping nut (21) supplied.
Press the spindle lock button (3) to
lock the grinding spindle. To tighten
the quick-clamping nut (21), fold up
the bar and turn the quick-clamping
nut firmly clockwise. Then fold down
the bar to secure the quick-clamping
nut. It is not sufficient to tighten the
disc along the edge.
Quick-clamping nuts (21) 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 mounting 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.
A plastic part (O-ring) is fitted around
the centring collar in the mounting
flange (17). If the O-ring is missing
or damaged, the mounting
flange (17) 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.

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 F)
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 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
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.
