– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
A GDE 16 Plus (accessory) is required for dust extraction.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Operation

Starting Operation

Inserting the battery
– Set the rotational direction switch 8 to the centre position
to protect the power tool against accidental starting.
– Insert the charged battery pack 11 from the rear into the
base of the power tool. Press the battery pack completely
into the base until the red stripe can no longer be seen and
the battery pack is securely locked.
Setting the operating mode
The operating mode of the power tool is selected with the
mode selector switch 13.
Note: Change the operating mode only when the machine is
switched off! Otherwise, the machine can be damaged.
– To change the operating mode, push the release button 12
and turn the mode selector switch 13 to the requested po-
sition until it can be heard to latch.
Position for hammer drilling in concrete or
stone
Position for drilling without impact in wood,
metal, ceramic and plastic as well as for
screwdriving
Vario-Lock position for adjustment of the
chiselling position
The mode selector switch 13 does not latch in
this position.
Position for chiselling
Reversing the rotational direction
The rotational direction switch 8 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 10 actuated.

Right rotation: Move the rotational direction switch 8 all the
way to position .
Left rotation: Move the rotational direction switch 8 all the
way to position .
Set the direction of rotation for hammer drilling, drilling and
chiselling always to right rotation.
Switching On and Off
To save energy, only switch the power tool on when using it.
– To start the machine, press the On/Off switch 10.
When starting the machine for the first time, a starting delay
is possible, as the electronic system of the power tool has to
configure itself first.
– To switch off the machine, release the On/Off switch 10.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on power tool can be
variably adjusted, depending on how far the On/Off switch 10
is pressed.
Light pressure on the On/Off switch 10 results in low
speed/impact rate. Further pressure on the switch increases
the speed/impact rate.
Electronic Precision Control (EPC) (see figure L)
EPC assists you when working with impact in sensitive mate-
rials by ensuring slow start-up and reduced operating speed.
– Slide the EPC switch 30 to the desired position.
Position for maximum operating speed
Position for slow start-up and reduced operating
speed
Overload Clutch
 If the tool insert becomes caught or jammed, the drive
to the drill spindle is interrupted. Because of the forces
that occur, always hold the power tool firmly with both
hands and provide for a secure stance.
 If the power tool jams, switch the machine off and loos-
en the tool insert. When switching the machine on with
the drilling tool jammed, high reaction torques can oc-
cur.
Rapid Shut-off (ERC)
The rapid shut-off feature enables better control of the power
tool. The power tool shuts off in case of sudden and unexpect-
ed rotation of the power tool around the drilling axis.
Rapid shut-off is indicated by flashing of the worklight 14 on
the power tool.
– To restart the machine, release the On/Off switch and
then actuate again.
 Rapid shut-off can trigger only when the power tool is
running at maximum operating speed and can rotate
freely around the drill bit axis. Choose a suitable work
position for this. Otherwise, rapid shut-off will not be en-
sured.
