Switching On and Off
To start the machine, press the On/Off switch 7 and
keep it depressed.
The power light 10 lights up when the On/Off switch 7
is halfway or fully depressed, and enables illumination
of the screwing location in unfavourable light condi-
tions.
To switch off the machine, release the On/Off switch
7.
Adjusting the Speed
The speed of the switched on power tool can be varia-
bly 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.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 7 is not pressed, the drill spin-
dle 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.
Temperature Dependent Overload Protection
When using as intended for, the power tool cannot be
subject to overload. When the load is too high or the
allowable battery temperature range of 0–70 °C is
exceeded, the speed is reduced. The power tool will
not run at full speed until reaching the allowable battery
temperature.
Protection Against Deep Discharging
The Li-ion battery is protected against deep discharg-
ing by the "Electronic Cell Protection (ECP)". When
the battery is empty, the machine is switched off by
means of a protective circuit: The inserted tool no
longer rotates.
Working Advice
Apply the power tool to the screw only when
it is switched off. Rotating tool inserts can slip off.
Soft Grip
The gripping surface (soft grip) 5 reduces the danger
of slipping and thereby improves the grip on the
machine and the handling.
At the same time, the rubber coating achieves a vibra-
tion-reducing effect.
Tips
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.

Before screwing larger, longer screws into hard mate-
rials, it is advisable to predrill a pilot hole with the core
diameter of the thread to approx.
length.
Maintenance and Service
Maintenance and Cleaning
Before any work on the machine (e. g., main-
tenance, tool change, etc.) as well as during
transport and storage, set the rotational
direction switch to the centre position. Unin-
tentional actuation of the On/Off switch can lead to
injuries.
For safe and proper working, always keep the
machine and ventilation slots clean.
When the battery is no longer operative, please refer to
an authorised after-sales service agent for BTI power
tools.
If the machine should fail despite the care taken in man-
ufacturing 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 6-digit order number given on the
nameplate of the machine.
Transport
The battery is tested according to UN document
ST/SG/AC.10/11/Rev.3 Part III, subsection 38.3. It
has effective protection against internal overpressure
and short circuiting as well as devices for the preven-
tion of violent rupture and dangerous reverse current
flow.
The lithium-equivalent content in the battery is below
applicable limit values. Therefore, the battery is not sub-
ject to national or international regulations pertaining to
dangerous mediums, neither as an individual compo-
nent nor when inserted into a machine. However, the
regulations governing dangerous goods may be rele-
vant when transporting several batteries. In this case, it
can be necessary to comply with special conditions
(e.g., concerning the packaging).
