Approved abrasive tools
You can use all the abrasive tools mentioned in these operat-
ing instructions.
The permissible speed [min -1 ] 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-

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.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.

Operation
Start-Up
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Hold the tool by the insulated gripping surfaces and
u
auxiliary handle only. The application tool could come
into contact with hidden wiring or its own cord. Con-
tact with live wires may make metal parts of the tool live,
posing a risk of electric shock.
Switching on/off
To start the power tool, push the on/off switch (3) forwards
and then press it down.
To lock-on the pressed on/off switch (3), push the on/off
switch (3) further forwards.
To switch off the power tool, release the on/off switch (3);
or, if the switch is locked, briefly press the on/off switch (3)
and then release it.
Switch without locking mechanism (country-specific):
To start the power tool, push the on/off switch (3) forwards
and then press it down.
To switch off the power tool, release the on/off switch (3).
Always check abrasive tools before using them. The
u
abrasive tool must be fitted properly and be able to
move freely. Carry out a test run for at least one
minute with no load. Do not use abrasive tools that are
damaged, run untrue or vibrate during use. Damaged
abrasive tools can burst apart and cause injuries.
Kickback control
If there is a sudden kickback in the power tool,
e.g. jamming in a separating cut, the power
supply to the motor will be interrupted elec-
tronically.
To restart the tool, set the On/Off switch (3) to the "off" po-
sition and then switch the power tool on again.
Restart protection
The restart protection feature prevents the power tool from
uncontrolled starting after the power supply to it has been
interrupted.
To restart the tool, set the on/off switch (3) to the "off" posi-
tion and then switch the power tool on again.
