b) Removing and inserting the rechargeable battery
For removing the rechargeable battery, press (A) the two lateral push-buttons for
unlocking it (7).
Then, the rechargeable battery can be pulled out downwards (B).
For inserting the rechargeable battery it is to position with its correct orientation at
the bottom of the cordless screwdriver up to the point at which it engages.
Figure 1
c) Inserting/removing the tool into/out of the drill chuck
For safety reasons, first the turn-over switch (5) is to be set to its central position to block the on/off switch (8).
Open the drill chuck by holding the internal ring (F) with one of your hands and turning the
outer ring (E) with your other hand anticlockwise (C, seen from front to the drill chuck).
Insert the desired tool (a drill in the figure) into the drill chuck.
Screw on the drill chuck by holding the internal ring (F) with one of your hands and turning
the outer ring (E) with your other hand clockwise (D, seen from front to the drill chuck).
To ensure that the tool (e.g. a bore bit or a drill) is fixed in the drill
chuck, it should be positioned at least 1 cm deep in the drill chuck
(bore bits or small drills). Large drills are to be inserted completely.
Proceed as described above to remove the tool.
Open the drill chuck by holding the internal ring (F) with one of your hands and turning the
outer ring (E) with your other hand anticlockwise.

d) Setting the torque or selecting the drill mode
By turning the torque-setting ring (2) the desired torque can be set at which the sliding clutch is
activated. Thus, the screw cannot be overtightened, e.g. when screwing it in; the screw flushes with
the material surface if the torque setting has been selected properly.
For drilling the setting ring can be set to a special position (marked by a drill symbol). In this position
the sliding clutch is deactivated, the torque is not limited.
Figure 3
The higher the setting value (see imprint at the cordless screwdriver), the higher the torque available:
Low setting value:
soft materials, small screws
High setting value:
hard materials, large screws
Drill symbol:
no torque limitation
For screwing out screws select a higher value or the “Drill” setting (drill symbol).
e) On/off switch
To be able to operate the on/off switch (8), the turn-over switch (5) must not be at its central position (in this position the on/off
switch is blocked).
The number of revolutions of the drive depends on the degree to which the on/off switch (8) is pressed.
In this way, the speed can be adjusted continuously from standstill up to maximum number of revolutions.
If the on/off switch is released, the drive will be slowed down (“Rotation stop”).
f) Function of the change-over switch (with turn-on lock)
Via the turn-over switch (5) you can switch between left and right senses of rotation.
The correct sense of rotation is to be selected according to the kind of work, whether holes are to be bored or a screw is to be
screwed in or out.
In its central position the turn-over switch blocks the on/off switch (8) and consequently the motor in the cordless screwdriver. Thus, you are able
to change the tools safely.
Change only the sense of rotation of the drive, if the cordless screwdriver has stopped completely. Otherwise, the drive
might be damaged.
g) Selecting the gear speeds (“HIGH”/ “LOW”)
A switch (4) is provided on the top of the cordless screwdriver. By means of this switch the two speeds can be selected.
LOW
1. speed, low number of revolutions, high torque
HIGH
2. speed, high number of revolutions, low torque
The switch for selecting the two speeds may only be activated, if the drive of the cordless screwdriver has stopped
completely. Otherwise, the drive might be damaged.
If one of the two speeds cannot be set by activating the switch, the driving toothed wheels are probably in an unfavourable
position.
In this case, activate the on/off switch (8) slightly so that the toothed wheels move a little bit.
h) Checking the rechargeable battery state
On top of the cordless screwdriver a small display and a check key are provided.
If the check key is activated, the current charge state is indicated. See figures on the right.
Figure 4
Only activate the check key, if the drive of the cordless screwdriver has stopped completely. Otherwise, the indication is not
correct because the high power consumption of the motor falsifies the measured value.
