When using diamond cutting discs, pay atten-
tion that the direction-of-rotation arrow on the 
diamond cutting disc and the direction of rota-
tion of the machine (see direction-of-rotation ar-
row on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on 
the clamping nut 

12

 and tighten with the two-

pin spanner; see Section “Quick-clamping Nut ”.

f

After mounting the grinding tool and before 
switching on, check that the grinding tool is 
correctly mounted and that it can turn free-
ly. Make sure that the grinding tool does 
not graze against the protection guard or 
other parts.

Quick-clamping Nut

For convenient changing of grinding tools with-
out the use of additional tools, you can use the 
quick-clamping nut 

11

 instead of the clamping 

nut 

12

.

f

The quick-clamping nut 11 may be used only 
for grinding or cutting discs.

Use only a flawless, undamaged quick-clamp-
ing nut 11.
When screwing on, pay attention that the side 
of the quick-clamping nut 11 with printing 
does not face the grinding disc; the arrow must 
point to the index mark 20.

Lock the grinder spin-
dle with the spindle 
lock button 

3

. 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.

Rotating the Machine Head

f

Before any work on the machine itself, pull 
the mains plug.

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 cutting operations using the cutting 
guide with dust extraction protection guard 

17

or 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.
