 and clamp the tool bit with 

open-end spanner

turning in clockwise direction.

The grinding tools must run completely concen-
trical. Do not continue to use out-of-round grind-
ing accessories, instead, replace before contin-
uing to work.

f

Do not tighten the collet chuck of the 
clamping nut as long as no grinding acces-
sory is mounted. 

Otherwise, the collet chuck 

can become damaged.

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.

– 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.

f

Prevent dust accumulation at the work-
place. 

Dusts can easily ignite.

Operation

Starting Operation

f

Observe correct mains voltage! The voltage 
of the power source must agree with the 
voltage specified on the nameplate of the 
machine. Power tools marked with 230 V 
can also be operated with 220 V.

Switching On and Off

 or, if it is locked, briefly push down the 

back of the On/Off switch 

5

 and then release it.

Kickback stop

In case of a sudden drop in speed, e.g., caused 
by a jammed disc while cutting, the power sup-
ply to the motor is electronically interrupted.
To 

restart the operation

, switch the On/Off 

switch 

5

 to the Off position and start the ma-

chine again.

Constant Electronic Control

Constant electronic control holds the speed 
constant at no-load and under load, and ensures 
uniform working performance.
