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 2 is used to reverse the
rotational direction of the machine. However, this is
not possible with the On/Off switch 3 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 direction switch 2
through to the right stop.
Switching On and Off
To start the machine, press the On/Off switch 3 and
keep it pressed.
To lock the pressed On/Off switch 3, press the lock-
on button 4.
To switch off the machine, release the On/Off switch
3 or when it is locked with the lock-on button 4, briefly
press the On/Off switch 3 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 3 is pressed.
Light pressure on the On/Off switch 3 results in a low
rotational speed. Further pressure on the switch
results in an increase in speed.
Working Advice
Apply the power tool to the screw/nut only
when it is switched off. Rotating tool inserts can
slip off.
For drilling in metal, use only perfectly sharpened HSS
drill bits (HSS=high-speed steel). The appropriate
quality is guaranteed by the BTI accessories program.

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 BTI
power tools.
In all correspondence and spare parts orders, please
always include the 7-digit order number given on the
nameplate 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.
