used (see figures in the front part of the operating manual),
and tighten them with the two-pin spanner (see " Quick-
clamping nut ", page 29).
u
After fitting the abrasive tool, check that the abrasive
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.
A plastic part (O-ring) is fitted around the cent-
ring collar in the mounting flange (12) . If the
O-ring is missing or damaged, the mounting
flange (12) must be replaced before operation
can resume.
Quick-clamping nut
To change the abrasive tool easily without having to use any
additional tools, you can use the quick-clamping nut (20) in-
stead of the clamping nut (19) .
u
The quick-clamping nut (20) may be used only for
grinding or cutting discs.
Only use quick-clamping nuts (20) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the
quick-clamping nut (20) is not facing the grinding disc;
the arrow must be pointing towards the index mark (33).
(33)
Press the spindle lock but-
ton (2) to lock the grinding
spindle. To tighten the
quick-clamping nut, turn
the grinding disc firmly
clockwise.
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.
Approved abrasive tools
You can use all the abrasive tools mentioned in these operat-
ing instructions.
The permissible speed [min -1 ] 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)
u
Pull the plug out of the socket before carrying out any
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 (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.
