temperature of the battery pack may rise slightly
during the charging operation. This is normal. If
the red LED flashes after the battery has been
inserted, the battery is defective. In this case, pull
out the mains plug of the charger immediately
and remove the defective battery. Do not use the
defective battery again. If the red LED lights up
while the battery pack is in the charger, the
charging temperature is either too high or too low.
In this case, pull out the mains plug of the charger
and charge the battery in an environment in which
the temperature is either warmer or colder.
If the battery pack fails to become charged, please
check
n whether there is voltage at the socket-outlet
n whether there is proper contact at the charging
contacts on the charger.
If the battery still fails to become charged, please
return
n the charger
n the battery pack
to our Customer Service Department.
To ensure that the battery pack provides long service,
you should take care to recharge it promptly. You must
recharge the battery pack when you notice that the
power of the cordless screwdriver drops.
Never fully discharge the battery pack. This will cause
it to develop a defect!
6.2 Torque setting (Fig. 4 / Item 1)
Important! The tool must be at a standstill when
you set the torque with the setting ring.
The cordless screwdriver is fitted with a mechanical
torque selector.
The torque for a specific size of screw is selected
with the set-collar (1). The correct torque depends on
several factors:
n on the type and hardness of material in question
n on the type and length screws used
n on the requirements needing to be met by the
screwed joint.
The clutch disengages with a grating sound to
indicate when the set torque is reached.
6.3 Drilling (Fig. 4 / Item 1)
For drilling purposes, move the set-collar to the last
step „Drill“. In this setting the slip clutch is inactive.
The maximum torque is available in drilling mode.
6.4 Forward/Reverse switch (Fig. 5 / Item 3)
With the slide switch above the On/Off switch you
can select the direction of rotation of the battery-
powered drill/screwdriver and secure it against being
switched on accidentally. You can choose between
clockwise and anticlockwise rotation. To avoid
causing damage to the gearing it is advisable to
change the direction of rotation only when the tool is
at a standstill. The On/Off switch is blocked when the
slide switch is in centre position.
6.5 On/Off switch (Fig. 5 / Item 4)
Infinitely variable speed control is possible with the
On/Off switch. The further you press the switch, the
higher the speed of the battery-powered
drill/screwdriver.
6.6 Changing over from 1st gear to 2nd gear
(Fig. 6 / Item 7)
You can work at a higher or lower speed depending
on the position of the selector switch. To avoid
damaging the gear unit you should only change over
gears when the tool has stopped.
6.7 Battery capacity indicator (Fig. 7 – Item 2)
Press the battery capacity indicator switch (a). The
battery capacity indicator (2) shows the charge
status of the battery using 3 LEDs.
All 3 LEDs are lit:
The battery is fully charged.
2 LEDs are lit:
The battery has an adequate remaining charge.
1 LED is lit:
The battery is empty, recharge the battery.
6.8 LED lamp (Fig. 7 / Item 10)
The LED lamp (10) can be used in poor lighting
conditions to illuminate the area where you want to
drill or screw. The LED lamp (10) will be lit
automatically as soon as you press the ON/OFF
switch (4).
6.9 Changing the tool (Fig. 8)
Important. Set the changeover switch (3) to its
centre position whenever you carry out any work (for
example changing the tool, maintenance work, etc.)
on the cordless screwdriver.
n The cordless screwdriver is fitted with a quick-
action chuck (9) with an automatic spindle stop.
n Open the chuck (9). The chuck opening (a) must
be large enough to hold the tool (drill bit or
screwdriver bit).
n Select the suitable tool. Push the tool as far as
