Air Supply
The supplied air must be free of foreign material and hu-
midity to protect the machine from damage, contamina-
tion and rust.
The use of a pressurised air maintenance unit is
necessary.
All fittings, connecting lines and hoses must be dimen-
sioned for the required air pressure and volume.
Avoid restrictions in the air supply resulting from, e.g.,
pinching, kinking or stretching!
In case of doubt, measure the pressure with an pressure
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
switchs 9+10 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 2 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 torque-dependent
ratcheting clutches that can be ad-
justed over a wide range. They re-
spond when the adjusted torque is
reached.
Switch Start with Ratcheting Clutch
Switching on: Press the on/off switch 9 for right rota-
tion or the on/off switch 10 for left ro-
tation. When the torque set for the
driving action is reached, the driver
ratchets until the on/off switch 9 or 10
is released.
Switching off: Release the on/off switches 9+10 for
left rotation or on/off switch 9 for right
rotation.
If the on/off switches 9+10 for left rotation or
on/off switch 9 for right rotation is released
prematurely, the pre-set torque will not be
achieved.

Type of Clutch
The machines have torque-dependent
switch-off clutches that can be ad-
justed over a wide range. They re-
spond when the adjusted torque is
reached.
Thrust and Pressure Start
with Switch-Off Clutch
Switching on: Press the on/off switch 9 or on/off
switch 10 and apply axial pressure to
the tool at the same time.
Switching off: The tool switches off automatically
when the torque setting is reached.
If the on/off switches 9+10 or on/off switch 9
are released or the pressure on the tool is re-
lieved prematurely, the pre-set torque will not
be achieved.
