Operation
Starting Operation
Observe correct mains voltage! The voltage of the pow-
er 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.
Reversing the Rotational Direction (see figures C–D)
The rotational direction switch 7 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 6 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 7 left to the stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 7 through to the
right stop.
Setting the Operating Mode
Drilling and Screwdriving
Set the selector switch 4 to the "Drilling" symbol.
Impact Drilling
Set the selector switch 4 to the "Impact drilling"
symbol.
The selector switch 4 engages noticeably and can also be ac-
tuated with the machine running.
Switching On and Off
To start the machine, press the On/Off switch 6 and keep it
pressed.
To lock the pressed On/Off switch 6, press the lock-on button 5.
To switch off the machine, release the On/Off switch 6 or
when it is locked with the lock-on button 5, briefly press the
On/Off switch 6 and then release it.
Adjusting the Speed/Impact Frequency
The speed/impact rate of the switched on power tool can be
variably adjusted, depending on how far the On/Off switch 6
is pressed.
Light pressure on the On/Off switch 6 results in low speed/im-
pact rate. Further pressure on the switch increases the
speed/impact rate.
Working Advice
Apply the power tool to the screw/nut only when it is
switched off. Rotating tool inserts can slip off.
After longer periods of working at low speed, allow the ma-
chine to cool down by running it for approx. 3 minutes at max-
imum speed with no load.
