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 assembly instructions.
To fasten the grinding/cutting disc, screw on the clamping
nut (14) and tighten with the two-hole spanner (see " Quick-
clamping nut ", page 27).
After fitting the abrasive tool, check that the abrasive
u
tool is fitted correctly and can turn freely before
switching on the power tool. Make sure that the abras-
ive tool does not brush against the protective guard or
other parts.
A plastic part (O-ring) is fitted around the cent-
ring collar in the mounting flange (9). If the O-
ring is missing or damaged, the mounting
flange (9) must be replaced before operation
can resume.

at the end of the grinding spindle thread. Tighten the cup
brush/disc brush with an open-ended spanner.
Quick-clamping nut
To change the abrasive tool easily without having to use any
additional tools, you can use the quick-clamping nut (13) in-
stead of the clamping nut (14).
The quick-clamping nut (13) may be used only for
u
grinding or cutting discs.
Only use quick-clamping nuts (13) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the
quick-clamping nut (13) is not facing the grinding disc;
the arrow must be pointing towards the index mark (26).
