f

The quick-clamping nut 11 may be used only for grind-

ing or cutting discs.

Use only a flawless, undamaged quick-clamping 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 27.

Lock the grinder spindle with 

the spindle lock button 

1

. To 

tighten the quick-clamping 

nut, firmly turn the grinding 

disc in clockwise direction.

A properly attached, undam-

aged quick-clamping nut can 

be loosened by hand when 

turning the knurled ring in an-

ticlockwise direction.

Never loosen a tight quick-

clamping nut with pliers. Al-

ways use the two-pin span-

ner.

 Insert the two-pin span-

ner 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 circumferential speed 

[m/s] of the grinding tools used must at least match the values 

given in the table.
Therefore, observe the permissible 

rotational/circumferen-

tial speed

 on the label of the grinding 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 machine housing in 

90 °  steps. In this man-

ner, the On/Off switch 

can be brought into a 

more convenient position 

for special working situa-

tions, e. g., for cutting op-

erations using the cutting 

guide with dust extrac-

tion protection guard 

24

 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. Touching or breathing-in the dusts can cause 

allergic reactions and/or lead to respiratory infections of 

the user or bystanders.

Certain dusts, such as oak or beech dust, are considered 

as carcinogenic, especially in connection with wood-treat-

ment additives (chromate, wood preservative). Materials 

containing asbestos may only be worked by specialists.

– As far as possible, use a dust extraction system suita-

ble for the material.

– Provide for good ventilation of the working 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 workplace. 

Dusts can 

easily ignite.

Operation

Starting Operation

f

Observe correct mains voltage! The voltage of the pow-

er 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.

When operating the machine with power from mobile genera-

tors that do not have sufficient reserve capacity or are not 

equipped with suitable voltage control with starting current 

amplification, loss of performance or untypical behavior can 

occur upon switching on.

Please observe the suitability of the power generator being 

used, particularly with regard to the mains voltage and fre-

quency.
