Setting the torque
You can set the desired torque in several steps
using the torque selection collet
III . With the cor-
rect setting, the insert tool is stopped as soon as
the screw is flush with the material or when the set
torque is reached.
When backing off screws, it may be necessary to
select a higher setting or to set the collet to the
"Drill“ or "max“ symbol.
Mechanical gear selection (Option)
With the gear selector switch IV , you can preselect
two speed ranges.
Tool holding fixture in the drill spindle
(Option)
Bits IX can be inserted directly into the hexagon-
shaped socket 2 in the drill spindle 1 , making the
machine shorter and lighter.

After working for a long time at low speed, you
should run the power tool for approx. 3 minutes at
maximum speed in idle to allow it to cool.
Drilling
Always select the speed to suit the material in
question and the drill bit diameter.
1 Low speed range, high torque; for
drilling, fixing screws and thread cut-
ting.
2
High speed range; for drilling with
small diameters
-NOTE-
The changeover must not be done at full load or
maximum speed.
In this way, you can increase the service life of
your machine.
Changing the tool
Remove the battery from the device
before undertaking any work on the
device.
This safety measure prevents acci-
dental starting of the power tool.
Wear safety gloves when changing
the tool .
The tool insert can become very hot
after working for long periods and/or
the cutting edges of the tool insert
are sharp.
If the On/Off switch VI is not pressed,
the drill spindle and thus the tool
holding fixture are locked.
