In case of doubt, measure the pressure with an pres-
sure gauge at the air inlet with the machine switched
on.
Maintenance Unit
The maintenance unit ensures fault-free functioning of
pneumatic tools.
It consists of three major components:
–
Filter with water separator
–
Pressure reduction valve with pressure gauge
–
Mist oiler
Lubricant in the mist oiler: Motor oil SAE 10/SAE 20.
Do not use paraffin or diesel oil.
Adjust the mist oiler so that a thin film of oil collects on
the air outlet.
Observe the operating instructions of the maintenance
unit.
Putting into Operation
The machine operates optimally with a pressure of
6.3 bar (90 psi) measured at the air inlet with the ma-
chine running.
Before connecting to the air supply, operate the on-off
switch 7 several times.
Switching On/Off
If the machine does not start, e.g. after not being used
for a longer time, disconnect the air supply and turn
the tool holder 1 by hand. Adhesive forces are elimi-
nated in this manner.
For an interruption of the air supply or reduced
operating pressure, switch off the machine.
Check the operating pressure and start again
when the pressure returns to normal.
Type of Clutch
The machines have a disengaging
clutch with a depth stop.
sponds when the depth stop comes
into contact with the work piece.
Switch Start with Disengaging Clutch
Switching on: Press the on/off switch 7 and press
the screwdriver bit of the running ma-
chine quickly and firmly against the
screwing position until the depth stop
comes in contact with the work piece.
When the screw-in depth setting is
reached, the disengaging clutch sepa-
rates the tool holder from the drive un-
til the on/off switch 7 is released.
Switching off: Release the on/off switch 7.
For premature releasing of the on/off switch 7,
the pre-set screwing depth will not be
reached.

Working Instructions
Before performing any work on the machine it-
self, disconnect the air supply.
Stick the tool inserts into the tool holder 1 until the
engaging of the detent is felt.
Adjusting the Screw-In Depth
The desired screw-in depth is set by turning the depth
stop 2.
Turning in the clockwise direction results in a more
screw-in depth. Turning in the counter clockwise di-
rection results in less screw-in depth.
The depth stop 2 has a detent ever quarter turn.
After the adjustment
Adapt the screw-in depth by trial screwings in the ma-
terial to be worked.
For higher torques, a correspondingly greater
counter force is necessary.
With a clamping device in the area 3, this counter
force can more easily be counteracted.
Machines that are operated with a torque greater than
7 Nm are to be used with a clamping device or an aux-
iliary handle.
Take care that the auxiliary handle or the clamping de-
vice holds the unit in a firm and secure manner.
Reversing Rotational Direction
Right rotation: Set the right/left rotation switch 4 to
the right.
Left rotation: Set the right/left rotation switch 4 to
the left.
Loosening Screws
So that the clutch engages after the switch-over, turn
the depth stop 2 counter clockwise to the stop.
