Quick-clamping Nut
For convenient changing of grinding tools with-
out the use of additional tools, you can use the
quick-clamping nut
13
instead of the clamping
nut
12
.
f
The quick-clamping nut 13 may be used only
for grinding or cutting discs.
Use only a flawless, undamaged quick-clamp-
ing nut 13.
When screwing on, pay attention that the side
of the quick-clamping nut 13 with printing
does not face the grinding disc; the arrow must
point to the index mark 27.
Lock the grinder spin-
dle with the spindle
lock button
1
. To tight-
en the quick-clamping
nut, firmly turn the
grinding disc in clock-
wise direction.
A properly attached,
undamaged quick-
clamping nut can be
loosened by hand
when turning the
knurled ring in anti-
clockwise direction.
Never loosen a tight
quick-clamping nut
with pliers. Always
use the two-pin span-
ner.
Insert the two-pin spanner as shown in the
illustration.
Approved Grinding Tools
All grinding tools mentioned in these operating
instructions can be used.
The permissible speed [min
-1
] or the circumfer-
ential speed [m/s] of the grinding tools used
must at least match the values given in the table.
Therefore, observe the permissible
rotational/
circumferential speed
on the label of the grind-
ing tool.
Rotating the Machine Head
f
Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as
during transport and storage, remove the
battery from the power tool.
There is danger
of injury when unintentionally actuating the
On/Off switch.
The machine head
can be rotated with
respect to the ma-
chine housing in
90° steps. In this
manner, the On/Off
switch can be
brought into a more
convenient posi-
tion for special
working situations, e.g. for left-handed persons.
Completely unscrew the four screws. Rotate the
machine head carefully,
without removing it
from the housing,
to the new position. Screw in
and tighten the four screws again.
