used (see figures in the front part of the operating manual),
and tighten them with the two-pin spanner (see " Quick-
clamping nut
", page 33).
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
(10) . If the
O-ring is missing or damaged, the mounting
flange (10) 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
(14) in-
stead of the clamping nut (15) .
u
The quick-clamping nut (14) may be used only for
grinding or cutting discs.
Only use quick-clamping nuts (14) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the
quick-clamping nut
(14) is not facing the grinding disc;
the arrow must be pointing towards the index mark (32).
(32)
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.

head carefully, without removing it from the housing , into
the new position ( ➋ ). Screw in and retighten the 4

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.
