Grinding/cutting disc
English
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 re-
ducer.
When using diamond cutting discs, ensure that the
arrow indicating the direction of rotation on the dia-
mond cutting disc matches the direction of rotation
of the power tool (see the direction of rotation ar-
row on the machine head).
See the graphics page for assembly instructions.
To fasten the grinding/cutting disc, screw on the
clamping nut (9) and tighten with the two-hole
spanner. (see " Quick-clamping nut
page 24).
After fitting the abrasive tool, check that the
u
abrasive tool is fitted correctly and can turn
freely before switching on the power tool.
Make sure that the abrasive tool does not
brush against the protective guard or other
parts.
A plastic part (O-ring) is fitted around
the centring collar in the mounting
flange (7). If the O-ring is missing or
damaged, the mounting flange (7)
must be replaced before operation can
resume.
Flap disc

Always fit the hand guard (15) when working
u
with the flap disc.
Rubber sanding pad
English
Always fit the hand guard (15) when working
u
with the rubber sanding pad (16).
See the graphics page for fitting instructions.
Screw on the round nut (18) and tighten with the
two-pin spanner.
Cup brush/disc brush
English
Always fit the hand guard (15) when working
u
with the cup brush or disc brush.
See the graphics page for fitting instructions.
The cup brush/disc brush must be screwed onto
the grinding spindle until it rests firmly against the
grinding spindle flange 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 (10) instead of the clamping nut (9).
The quick-clamping nut (10) may be used
u
only for grinding or cutting discs.
Only use quick-clamping nuts (10) that are in
good working order and not damaged.
When screwing on, make sure that the printed
side of the quick-clamping nut (10) is not fa-
cing the grinding disc; the arrow must be
pointing towards the index mark (23).
Press the spindle lock button (2)
to lock the grinding spindle. To
(23)
tighten the quick-clamping nut,
turn the grinding disc firmly
",
clockwise.
If the quick-clamping nut has
been attached correctly and is
not damaged, you can loosen it
by hand by turning the knurled
ring anticlockwise. If the quick-
clamping nut is stuck, do not
attempt to loosen it with pli-
ers – always use the two-pin
spanner. Position the two‑pin
spanner as shown in the figure.
