OUR RECOMMENDATION: The preferred lubricatingmethod for the
screwdriver spindles mountedinfixtures, brackets, machines, etc., eachin
connection with acontroller, is methodb) withPoint-of-Use Oiler.
• Check pressureat directlyon the machine. The Regulator needs tobe
adjusted toanairflow between 5.0 (71 PSI)and6.3bar(90 PSI). Ahigher
pressureleads toincreased wear and tear. A lower pressure maylead to
clutchnot being able tocorrectlyshut-off the motor.
In regards toair-qualityaccordingtoISO8573-1, we recommend:

4Operation
Unless otherwise requested thedriver is preset to max. torque with the
strongest clutch spring.
Adjust clutch to therequiredtorque value. If necessary, exchangeclutch
spring. Thenecessarytorque adjustment canbetested, usinga DEPRAG
Torque Wrenchor Dynamometer (seeDEPRAG catalogs D3020 and D
3022). This equipment canalso be used tore-adjust thetorque of the
Screwdriver Spindle.
Operating theclutch using aclutchspring which exceeds
its allowable torque, leads to areduction of the torque
accuracy.
The driver starts by remote-valve.
The flowpressure should not dropbelow 5 bar (71PSI)!
The installationandconnectionof the Screwdriver Spindle requires the
following steps:
1. Adjust clutch to required torquesetting(see paragraph: Torque
Adjustment)
2. InstallScrewdriver spindleaccordingto picture: „Installation Tips for
screwdriver spindle“. If several Spindles are being installed, referto the
screwdriver arrangement on construction sheet (if you donot have this
constructionsheet, pleasecall us).
3. Connect mainairhose.
4. Connect pneumatic functioncontrolhose. This functioncontrolis under
pressureof 2,5 bar during actual screw-driving. Ifthe function control is
not needed, the port hasto be closed, otherwisethere isalossof
power of about 15%.
Pleasemake surenot toexceed the max. driver stroke (see Installation Tips
for screwdriverspindle)duringScrewdriving. The noise level can befurther
reduced, when an exhaust connection with connectedFilter/Silenceris used.
Attention:
Screwdriver is furnishedwith a clutch withleftshut-
off and left

4.4. Connection-Possibilitiesof the Function Control
•
Use as air pressure outletduring screw-assembly:
- to controldriver start and stop, as well as shut-off control of clutch;
- as cycle counterof the completeprocess;
eachin connectionwith a PE-Switchor similar.
• Use as air pressure inlet:
- if 6,3bar(90PSI) air pressure is given to thefunctioncontrol port,
the driver starts rotatingat about 15 %of its speed. This will
simplifytheengagement of bit/socket to fastener(for example
when driving hexscrews, nuts, etc.)
Function Description / Driver Start
