Quick-clamping nuts (15)
that are properly secured
and not damaged can be re-
moved 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 – always 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.
A plastic part (O-ring) is fitted around the cent-
ring collar in the hub flange
(9) . If the O-ring
is missing or damaged, the hub flange (9)
must be replaced before operation can re-
sume.
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.

Always fit the hand guard (21) when working with the
flap disc.

u
Always fit the hand guard (21) when working with the

Always fit the hand guard (21) when working with the
cup brush.

until it rests firmly against the grinding spindle flange at the
end of the grinding spindle thread. Tighten the cup brush
with an open-ended spanner.
Quick-clamping nut
To change the abrasive tool easily without having to use any
additional tools, you can use the quick-clamping nut
(13) in-
stead of the clamping nut (14) .
u
The quick-clamping nut (13) may be used only for
grinding or cutting discs.
Only use quick-clamping nuts (13) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the
quick-clamping nut
(13) is not facing the grinding disc;
the arrow must be pointing towards the index mark (28).

ton

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.
