Open the clamping ring by turning the additional
handle (1) anticlockwise. Push the additional

tighten the additional handle at the angle required
for the application.
7. Use
7.1 The machine's multifunctional monitoring
system
If the machine switches off automatically, the
machine electronics have activated automatic
protection mode. A warning signal sounds
(continuous beeping). The beeping stops after a
maximum of 30 seconds or when the trigger is
released (13).
In spite of this protective function, overloading
is still possible with certain applications and
can result in damage to the machine.
Causes and remedies:
1. Battery pack almost flat (the electronics
prevent the battery pack from discharging totally
and avoid irreparable damage).
If one LED is flashing (9), the battery pack is
almost flat. If necessary, press the (8) button
and check the LEDs (9) to see the charge level.
If the battery pack is almost flat, it must be
recharged.
2. Long continuous overloading of the machine will
activate the temperature cut-out.
Leave the machine or battery pack to cool.
Note: If the battery pack feels very warm, the
pack will cool more quickly in your "AIR
COOLED" charger.
Note: The machine will cool more quickly if you
operate it at idling speed.
3. If the current is too high (for example, if the
machine seizes continuously for long periods),
the machine switches off.
Switch off the machine at the trigger (13). Then
continue working as normal. Try to prevent the
machine from seizing.
7.2 Battery pack
Charge the battery pack before use (10).
If performance diminishes, recharge the battery
pack.
"Li-Power" li-ion battery packs have a capacity
and signal indicator: (9)
- Press the (8) button, the LEDs indicate the charge
level.
- If one LED is flashing, the battery pack is almost
flat and must be recharged.
7.3 Removing and inserting the battery pack
Removal:
Press the battery pack release (7) button and pull
the battery pack (10) forwards.
Inserting:
Slide in the battery pack (10) until it engages.

7.5 Selecting gear stage
Do not actuate the switch (5) unless the motor
has stopped completely!
If the switch (5) cannot be turned up to the stop,
however, press the trigger (13) slightly so that the
motor rotates slowly. It will then be possible to turn
the switch (5) all the way up to the stop.
Press the switch (5) (left or right of the machine).
1st gear setting (low speed),
very high torque
2nd gear setting (high speed)
7.6 Setting the torque limit
Press the slide switch (4).
1... = Torque setting (for working with torque
control)
Note: the torque can be adjusted to different
settings depending on the gear selected! In
2nd gear from 1.5 to 3.5 Nm and in 1st gear
from 3.5 to 12.5 Nm.
Note: Once the set torque has been reached, the
screwdriver clutch emits a rattling noise
and the machine is automatically switched
off.
= Drill setting - no torque control
(for max. torque)
7.7 Drilling and impact drilling
(depending on the model)
Press the slide switch (3).
= Impact drilling
Note: Always work at high speeds when
impact drilling.
= Normal drilling without impact
7.8 Activating the pulse function
(depending on the model)
Do not work for long periods with pulse
function switched on! (The motor can
overheat.)
Press the button (11) to activate or deactivate
the pulse function.
The button (11) flashes when the pulse function is
active.
Note: If the machine is not used for approx. 5
minutes, the pulse function switches off
automatically and the flashing button (11) goes out.
