c) Push the battery pack onto the battery charger. The red LED will come on to
indicate that the battery pack is being charged. When the charging process is
finished, the red LED will extinguish and green LED will be permanently lit. The
time it takes to fully recharge an empty battery is approximately 1 hour.
d) The temperature of the battery pack may rise slightly during the charging
operation. This is normal. If the green LED extinguishes during charging, the
temperature is either above or below the perfect charging temperature. In this
case, pull the 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
• whether there is voltage at the socket-outlet
• whether there is proper contact at the charging contacts on the charger.
If the battery still fails to become charged, please return
• the charger
• 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 the battery pack to develop
a defect.
2) Torque setting (Fig. 4 / Item 1)
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:
• on the type and hardness of material in question
• on the type and length screws used
• 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.
Important! The tool must be at a standstill when you set the torque with
the setting ring.
3) Drilling (Fig. 5 / 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.
4) Forward/Reverse switch (Fig. 6 / 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.
5) On/Off switch (Fig. 6 / 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) Changing over from 1st gear to 2nd gear (Fig. 7/ 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.
7) Battery capacity indicator (Fig. 8– Item 2)
The 3 color LEDs will indicate the status of battery capacity as soon as you press
the ON/OFF switch (4).
All LEDs illuminate:
The battery is fully charged.
The yellow and red LED illuminate:
