9 Operation
9.1 Switching on and off
 Pressing only the switch [1-2] does not start
the machine – it is not a machine fault!
 Upon screwing to the required depth, the power
tool switches off!
The machine can be switched on by means of sev-
eral methods:
a)
 Set the forward / reverse switch [1-3] into ma-
chine clockwise operation.
 Set the switch [1-4] into MAN position. In order
to switch on the power tool, apply the switch [1-
2] and concurrently press the bit on the screw.
Use the switch [1-2] to gradually regulate the
speed.
b)
 Set the forward / reverse switch [1-3] into ma-
chine clockwise operation.
 Set the switch [1-4] into AUTO position.
 Press the bit on the screw and the power tool
will switch on.
Switch [1-2] does not need to be pressed. Maxi-
mum speed is set automatically.
c)
 Set the forward / reverse switch [1-3] into ma-
chine anti-clockwise operation.
 In order to start the power tool, press the
switch [1-2]. The switch MAN/AUTO [1-4] is
16
in any position.
Use the switch [1-2] to gradually regulate the
speed.
 If the forward / reverse switch [1-3] is set to
anti-clockwise operation, the screwdriver can
be started only by pressing the switch [1-2] –
without additional pressure on the bit!
 It is not necessary to remove the depth stopper
in order to unscrew screws!
9.2 Depth stopper
Turning the depth stopper sets the screwing depth
– see fi gure [5]. The setting accuracy is approx ±
0.1 mm.
Anti-clockwise rotation =
Clockwise rotation
Upon setting the depth, set some screws to test
and adjust the depth.
Depth stopper assembly
 Fit the depth stopper [4-1] on the gear box [4-
5], until it engages in the groove.
Depth stopper disassembly
 Remove the depth stopper from the gear box
by pulling it.
9.3 Hook and clip
Use the clip [6-1] to temporarily attach the screw-
driver on the working clothing – it can be attached
by means of a screw [6-2] to the left or right of
the power tool, and it is suitable for right and left
handed people – see fi gure [6].
The screwdriver is equipped with a hook [7-1],
which is used for occasional machine suspension.
It can be attached to the left or right of the power
tool, by means of a screw [7-2] – see fi gure [7].
9.4 Auto feed attachment
The auto feed attachment enables to work con-
tinuously, without unnecessary delays.
