– 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.
Removing/fitting the dust filter
Remove any used dust filters (4) along with the screws in ac-
cordance with figure A. Fit a new dust filter in accordance
with figure B.
When fitting the dust filter (4), only use the original screws
to avoid damage to the electronics.
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
Status indicator (LED)

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.
Note: If the power tool starts up immediately after an inter-
ruption in the power supply, the restart protection feature
has failed.The power tool must be sent to the after-sales ser-
vice immediately; see the "After-Sales Service and Applica-
tion Service" section for addresses.
Soft start
The electronic soft start limits the torque when the power
tool is switched on and enables a smooth start-up.
Note: If the power tool runs at full speed immediately after
being switched on, this means that the soft start and restart
protection mechanisms have failed. The power tool must be
sent to the after-sales service immediately; see the "After-
Sales Service and Application Service" section for ad-
dresses.
Electronic Brake System
The power tool is fitted with an electronic
brake system. When the power supply is
switched off, the abrasive tool is brought to a
complete stop within a few seconds. This
means that the run-out time is shorter than for
angle grinders without an electronic brake system and en-
ables the power tool to be set down sooner.
Note: If the braking effect deteriorates noticeably, the elec-
tronic brake system has failed. The power tool must be sent
to the after-sales service immediately; see the "After-Sales
Service and Application Service" section for addresses.
Solution
–
status indicator (LED) lights up green, the
power tool can be switched on again.
Turn the power tool off and on again.
