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.
Reversing the Rotational Direction
The rotational direction switch 8 is used to reverse the
rotational direction of the machine. However, this is
not possible with the On/Off switch 7 actuated.
Right rotation: For driving in screws, push the rota-
tional direction switch 8 left to the stop.
Left rotation: Push the rotational direction switch 8
right to the stop (for unscrewing screws).
Switching On and Off
To start the machine, press the On/Off switch 7 and
keep it pressed.
To lock the pressed On/Off switch 7, press the lock-
on button 6.
To switch off the machine, release the On/Off switch
7 or when it is locked with the lock-on button 6, briefly
press the On/Off switch 7 and then release it.
Adjusting the Speed
The speed of the switched on power tool can be vari-
ably adjusted, depending on how far the On/Off
switch 7 is pressed.
Light pressure on the On/Off switch 7 results in a low
rotational speed. Further pressure on the switch
results in an increase in speed.
Adjusting the Screw-in Depth (see figure B)
With the adjustment sleeve 3, the screw-in depth of
the screw head into the workpiece can be preset in 8
locking steps per full turn. Each step corresponds
with a 0.25 mm change of the screw-in depth.
Turning the adjustment sleeve 3 in clockwise direction
results in a greater screw-in depth; turning in anti-
clockwise direction reduces the screw-in depth.
The required setting is best determined by testing.
Working Advice
Apply the power tool to the screw only when
it is switched off. Rotating tool inserts can slip
off.
Guide the screw toward the screwdriving bit 1. The
screw is held in place by the magnet pull of the univer-
sal bit holder 10. Firmly push the tip of the screw into
the material to be screwed until the screwing-depth
stop 4 faces against the workpiece.
12 | English
Switch the machine on. The screw is screwed into the
material until the adjusted screw-in depth is reached.
The drive is disengaged and the tool holder no longer
rotates. Check the screw-in depth and readjust, if
required.
For unscrewing screws, set the rotational direction
switch 8 to left rotation and pull off the screwing-
depth stop 4 toward the front without turning the
adjustment sleeve.
Working with the screwing-depth stop 4 is also pos-
sible when adapting the screw-in depth.
Belt Clip
With the belt clip 5, the machine can be hung onto a
belt. The user has both hands free and the machine is
always at hand.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
If the machine should fail despite the care taken in
manufacturing and testing procedures, repair should
be carried out by an after-sales service centre for
Berner power tools.
In all correspondence and spare parts orders, please
always include the article number given on the type
plate of the machine.
Disposal
The machine, accessories and packaging should be
sorted for environmental-friendly recycling.
Only for EC countries:
Do not dispose of power tools into
household waste!
According the European Guideline
2002/96/EC for Waste Electrical and
Electronic Equipment and its imple-
mentation into national right, power
tools that are no longer usable must be collected sep-
arately and disposed of in an environmentally correct
manner.
Subject to change without notice.
