If the quick-clamping nut
has been attached correctly
and is not damaged, you
can loosen it by hand by
turning the knurled ring an-
ticlockwise. 

If the quick-

clamping nut is stuck, do
not attempt to loosen it
with pliers – always use
the two-pin spanner.

 Posi-

tion the two‑pin spanner as
shown in the figure.

Grinding/cutting disc

Pay attention to the dimensions of the abrasive tools. The
diameter of the hole must match that of the mounting flange.
Do not use an adapter or reducer.
When using diamond cutting discs, ensure that the arrow in-
dicating the direction of rotation on the diamond cutting disc
matches the direction of rotation of the power tool (see the
direction of rotation arrow on the machine head).
See the graphics page for assembling instructions.
To fasten the grinding/cutting disc, screw on the clamping
nut 

(13)

 and tighten with the two-pin spanner; see the (see "

Quick-clamping nut 

 ", page 22) section.
