Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V can
also be operated with 220 V.
Setting the Operating Mode
The operating mode of the power tool is selected
with the mode selector switch 7.
Note: Change the operating mode only when the
machine is switched off! Otherwise, the machine
can be damaged.
Turn the mode selector switch 7 to the desired
position until it can be heard to latch.

crete or stone
Position for drilling without impact
in wood, metal, ceramic and plastic

Reversing the Rotational Direction
(see figure J)
The rotational direction switch 6 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 5 actuated.
Right rotation: Push the rotational direction
switch 6 rightward to the stop.
Left rotation: Push the rotational direction
switch 6 leftward to the stop.
Set the direction of rotation for hammer drilling,
drilling and chiselling always to right rotation.
Switching On and Off
To start the machine, press the On/Off switch 5.
To lock the On/Off switch, keep it pressed and
additionally push the lock-on button 4.
To switch off the machine, release the On/Off
switch 5. When the On/Off switch 5 is locked,
press it first and then release it.
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 5 is pressed.
Light pressure on the On/Off switch 5 results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
Safety 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 loosen the tool insert. When switch-
ing the machine on with the drilling tool
jammed, high reaction torques can occur.
