Operation
Starting Operation
Reversing the rotational direction (see figure C)
The rotational direction switch 2 is used to reverse the rotational direction of the ma-
chine. However, this is not possible with the On/Off switch 4 actuated.
Right Rotation: For drilling and driving in screws, push the rotational direction
switch 2 left to the stop.
Left Rotation: For loosening and unscrewing screws and nuts, press the rotational di-
rection switch 2 through to the right stop.
Switching On and Off
To start the machine, press the On/Off switch 4 and keep it pressed.
The power light 6 lights up when the On/Off switch 4 is slightly or completely pressed,
and allows the work area to be illuminated when lighting conditions are insufficient.
To switch off the machine, release the On/Off switch 4.
To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched-on power tool can be variably adjusted, depending on how
far the On/Off switch 4 is pressed.
Light pressure on the On/Off switch 4 results in a low rotational speed. Further pres-
sure on the switch results in an increase in speed.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 4 is not pressed, the drill spindle and thus the tool holder are
locked.
This enables screws to be screwed in, even when the battery is empty and allows for
the machine to be used as a screwdriver.
Run-on Brake
When the On/Off switch 4 is released, the chuck brakes to a stop, thus preventing the
run-on of the tool.
When driving in screws, wait until the screw is screwed in flush with the material and
then release the On/Off switch 4. By doing so, the head of the screw does not pene-
trate into the material.
