Switching on/off
Switching on
♦
Press the ON/OFF switch 5 and keep it
pressed in . The LED work light 8 lights up
when the ON/OFF switch 5 is pressed lightly
or fully . This provides illumination of the work
area in poor lighting conditions .
Switching off
♦
Release the ON/OFF switch 5 .
Setting the rotational speed
You can infinitely adjust the speed of the switched
on power tool, depending on how far the ON/
OFF switch 5 is pressed in .
♦
Select a low speed for small screws or soft
materials .
♦
Select a high speed for large screws, hard
materials or removing screws .
♦
Press the ON/OFF switch 5 only lightly to
achieve a low speed .
Increasing the pressure increases the speed .
Spindle lock
When the ON/OFF switch 5 is not pressed, the
quick-release chuck 7 is locked .
This makes it possible to screw in screws even when
the battery is discharged or to use the power tool
as a screwdriver .
Adjusting the tool head
You can set the quick-release chuck 7 into 5
different angular positions .
♦
Press the release button 9 and swivel the
quick-release chuck 7 to the desired position .
♦
Then let go of the release button 9 again .
♦
Before use, check whether the quick-release
chuck 7 is locked in the respective angular
position .
There is a risk of injury!

Tips and tricks
Tip! How to do things correctly.
♦
Before operating the appliance, check whether
the screw or drill bit is correctly positioned, i .e .
centred in the drill chuck .
♦
Screw bits are labelled according to their
dimensions and their shape . If you are uncer-
tain, always check first whether the bit fits tightly
in the screw head without any play .
Torque
♦
Smaller screws/bits can be damaged if you set
the torque or rotational speed too high .
Hard screw joints (in metal)
♦
Particularly high torques occur, e .g . in metal
screw joints when using drive sockets . Select
a low rotational speed .
Soft screw joints (e.g. in soft wood)
♦
Here, too, use a low speed to avoid damaging
the wood surface when it comes into contact
with the metal screw head . Use a countersink .
When drilling in wood, metal and other
materials, observe the following:
♦
Use a high speed for drill bits with a small
diameter and a low speed for drill bits with
a large diameter .
♦
Select a low speed for hard materials and a
high speed for soft materials .
♦
Secure or fasten the workpiece in a clamp or
vice (if possible) .
♦
Mark the spot where you want to drill using a
centre punch or nail . Select a low rotational
speed when starting .
♦
Pull the rotating drill bit from the hole repeatedly
to remove dust and chips and clear the hole .
