The quick-clamping nut
(12)
may be used only for
grinding or cutting discs.

that are in good work-
ing order and not damaged.

spindle. To tighten the
quick-clamping nut, turn
the grinding disc firmly

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.
Never loosen a
tight quick-clamping nut
with pliers. Always use
the combination wrench.
Insert the combination
wrench as shown in the fig-
ure.

Rotating the machine head
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 ap-
plications, e.g. for left-
handed tool users.
Completely unscrew the
four screws. Rotate the ma-
chine head carefully,
without removing it from the housing
, into the new posi-
tion. Screw in and retighten the four screws.
Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
