Do not press the spindle lock button while the grind-
u
ing spindle is moving. The power tool may become dam-
aged if you do this.
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
Quick-clamping nut section.
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 (11). If the
O-ring is missing or damaged, the mounting
flange (11) must be replaced before operation
can resume.
Flap disc
Always fit the hand guard (18) when working with the
u
flap disc.
Rubber sanding pad
Always fit the hand guard (18) when working with the
u
rubber sanding pad (19).
See the graphics page for fitting instructions.
Screw on the round nut (21) and tighten with the two-pin
spanner.
Cup brush/disc brush
Always fit the hand guard (18) when working with the
u
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 (14) in-
stead of the clamping nut (13).
The quick-clamping nut (14) may be used only for
u
grinding or cutting discs.
Only use quick-clamping nuts (14) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the
quick-clamping nut (14) is not facing the grinding disc;
the arrow must be pointing towards the index mark (26).

Approved abrasive tools
You can use all the abrasive tools mentioned in these operat-
ing instructions.
The permissible speed [min ] or the circumferential speed
-1
[m/s] of the abrasive tools used must at least match the val-
ues given in the table.
It is therefore important to observe the permissible rota-
tional/circumferential speed on the label of the abrasive
tool.

Rotating the machine head
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Press the spindle lock but-
ton (2) to lock the grinding
spindle. To 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 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.
