Quick-clamping Nut
❏ Use the quick-clamping nut only for grind-
ing/cutting discs with a diameter of up to
125 mm (max.).
X
After mounting the mounting flange and grind-
ing/cutting disc, the clear thread length "X of the
grinding spindle" must be at least 4 mm.
Lock the grinding spindle with the spindle lock but-
ton 2. Fold up the clip of the quick-clamping nut 13
and manually screw the nut onto the grinding spin-
dle in clockwise direction 6 until firmly seated on the
grinding/cutting disc. Fold the clip down again.
To release, fold up the clip of the quick-clamping nut
13 and manually unscrew the nut off of the locked
spindle in anticlockwise direction. If necessary, the
quick-clamping nut 13 can also be loosened with
the corresponding two-pin spanner 12 after folding
up the clip.
Approved Grinding Tools
All grinding tools mentioned in these operating
instructions can be used.
The permissible speed [rpm] 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/cir-
cumferential speed on the label of the grinding
tool.

❏ Before any work on the machine itself,
pull the mains plug.
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.
Dusts from materials such as lead-containing coat-
ings, 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 con-
sidered as carcinogenic, especially in connection
with wood-treatment additives (chromate, wood pre-
servative). Materials containing asbestos may only
be worked by specialists.
• Use dust extraction whenever possible.
• Provide for good ventilation of the working place.
• It is recommended to wear a P2 filter-class respi-
rator.
Observe the relevant regulations in your country for
the materials to be worked.

When operating the machine with power from
mobile generators that do not have sufficient reserve
capacity or are not equipped with suitable voltage
control with starting current amplification, loss of
45
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 frequency.
Rotating the Machine Head
The
machine
can be rotated with
respect to the machine
housing in 90° steps.
In this manner, the
On/Off switch can be
brought into a more
convenient position for
special working situa-
tions, e.g. for left-
handed persons.
