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 (13) and tighten with the two-hole spanner (see " Quick-
clamping nut ", page 22).
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 (10). If the
O-ring is missing or damaged, the mounting
flange (10) must be replaced before operation
can resume.
Flap disc
Always fit the hand guard (21) when working with the
u
flap disc.
Rubber sanding pad
Always fit the hand guard (21) when working with the
u
rubber sanding pad (23).
See the graphics page for fitting instructions.
Before fitting the rubber sanding pad (23), place the two
spacer discs (22) on the grinding spindle (18).
Screw on the round nut (25) and tighten with the two-pin
spanner.
Cup brush/disc brush
Always fit the hand guard (21) 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.

The permissible speed [min ] or the circumferential speed
[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.

Pull the plug out of the socket before carrying out any
u
work on the power tool.
The main handle (28) can be rotated 90° to the left or right
relative to the motor housing. This enables the on/off switch
to be brought into a more convenient position for particular
working situations, such as cutting operations using the ex-
traction guard for cutting with a guide block (20) or for left-
handed persons.
Pull back the handle release (29) in the direction of the ar-
row while simultaneously turning the main handle (28) until
it clicks into the required position.
Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
