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, 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 pro-
tection guard 

23

 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.

Dust/Chip Extraction

f

Dusts from materials such as lead-containing 
coatings, some wood types, minerals and 
metal can be harmful to one’s health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are 
considered as carcinogenic, especially in 
connection with wood-treatment additives 
(chromate, wood preservative). Materials 
containing asbestos may only be worked by 
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-

ing place.

– It is recommended to wear a P2 filter-

class respirator.

Observe the relevant regulations in your 
country for the materials to be worked.
