Quick-clamping Nut

For convenient changing of grinding tools with-

out the use of additional tools, you can use the

quick-clamping nut 12 instead of the clamping

nut 11.

f The quick-clamping nut 12 may be used only

for grinding or cutting discs.

Use only a flawless, undamaged quick-clamping

nut 12.

When screwing on, pay attention that the side

of the quick-clamping nut 12 with printing does

not face the grinding disc; the arrow must point

to the index mark 22.

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, un-

damaged quick-clamp-

ing 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 spanner.

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 circumfer-

ential speed [m/s] of the grinding tools used

must at least match the values given in the table.

Therefore, observe the permissible rotation-

al/circumferential 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 ma-

chine housing in 90°

steps. In this man-

ner, the On/Off

switch can be

brought into a more

convenient position

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.

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 con-

nection with wood-treatment additives (chro-

mate, wood preservative). Materials containing

asbestos may only be worked by specialists.
