Air Supply

The supplied air must be free of foreign material and
humidity to protect the machine from damage, con-
tamination 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 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 units with lever start to the air sup-
ply, operate the lever 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 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 0 607 461 001 / ... 201 / ... 202
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.
Type 0 607 461 001
Lever Start with Ratchet Clutch
Switching on: Press the lever 10.
When the torque setting for the screw-
ing operation is reached, the screw-
driver disengages until the lever 10 is
released.
Switching off: Release lever 10.
For premature releasing of the lever 10, the
pre-set torque will not be achieved.
Type 0 607 461 201 / ... 202
Thrust Start with Ratchet Clutch
Switching on: Apply axial pressure to the tool.
Switching off: The machine switches off when the
pressure on the tool is relieved.
When the tool is relieved prematurely, the
torque setting will not be reached.
Type 0 607 461 203 / ... 204 / ... 205 /
... 206 / ... 207
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.
Type 0 607 461 203 / ... 204 / ... 205 / ... 206
Thrust Start with Switch-Off Clutch
Switching on: Apply axial pressure to the tool.
Switching off: The machine switches off automatically
when the torque setting is reached.
When the tool is relieved prematurely, the
torque setting will not be reached.
Type 0 607 461 207
Lever Start with Switch-Off Clutch
Switching on: Press the lever 10.
Switching off: The machine switches off automatically
when the torque setting is reached.
For premature releasing of the lever 10, the
pre-set torque will not be achieved.
