3Installation
·
Blowout airlineandpressure hose,prior toconnection ittothetool.
· Makesure,thatall air lineshaveasufficientcross-section(see technical
data)andhosesmustbefree ofbends andkinks. The hoselengthshould
not exceed2meters.
· All DEPRAGScrewdrivers maybe operatedeither withor without
lubricatedair(see paragraph: Maintenanceand Upkeep). Best resultsare
achieved, when machineislubricatedwith1–2dropsofoil per1m3.
Whenoperatingwithoilfree air,aperformancereductionof upto20%
occursandmaintenancerequirementsincreases!
· Connect the equipment asfollows:
a) for standardoperation connectequipmenttoamaintenanceunit,

OUR RECOMMENDATION: The preferred lubricatingmethod for the
screwdriver spindles mountedinfixtures,brackets,machines,etc.,eachin
connection withacontroller,ismethodb) withPoint-of-UseOiler.
· Checkpressureat directlyon the machine.The Regulatorneedstobe
adjusted toanairflowbetween 5.0(71PSI)and6.3bar(90PSI).Ahigher
pressureleadstoincreased wear andtear.Alower pressure maylead to
clutchnot being abletocorrectlyshut-offthe motor.

4Operation
Unlessotherwiserequested thedriver ispresettomax.torque withthe
strongest clutchspring.Adjustclutchtotherequired torquevalue. If
necessary, exchange clutchspring.
Operatingtheclutchusing aclutchspring whichexceeds its
allowable torque,leadstoareductionofthetorque accuracy.
The necessarytorque adjustmentcanbe tested, usingaDEPRAG Torque
Wrenchor Measuring Platform(see DEPRAG catalogs D3020 andD3022).
This equipment canalsobeusedtore-adjustthetorque oftheScrewdriver
Spindle.
Attention:
Push-to-start-screwdriver!
The flowpressure should notdropbelow5bar (71PSI)!
The installationandconnectionofthe Screwdriver Spindle requiresthe
following steps:
1.Adjustclutchtorequired torquesetting(see paragraph: Torque
Adjustment).
2.InstallScrewdriver spindleaccordingtopicture: „Installation Tips for
screwdriverspindle“.
3.Connectmainairhose.
4.Connectpneumaticfunctioncontrolhose.Thisfunctioncontrolisunder
pressureof2,5bar during actual screw-driving. Ifthefunction control
isnotneeded, theporthastobeclosed, otherwisethereisalossof
power of about15 %.
Pleasemakesurenottoexceed the max. driver stroke(see Installation Tips
for screwdriverspindle)during Screwdriving. The noiselevel can befurther
reduced,when an exhaust connection withconnectedFilter/Silenceris used.

ChangeofClutch Spring (seepicture)
Toavoid loosingparts, itis recommended toonlydisassemble
the machineontop ofaflat worksurface.
1.Prior tochange ofclutchspring,disconnectdriver fromair/ power
supply.
2.Unscrewspringsleevecomplete(lefthand thread).
3.Unscrewclutchbearing complete(lefthand thread).
4.Takeoutthecompleteclutch.
5.Put wrench805492 (AF6)ontothehexof theclutchshaft and screwoff
adjustmentnut bymeans ofwrench805491 (AF11)(right-handthread).
6.Drawoff lock ring.
7.Takeoff clutchspring andassembleclutchinreverseorder.
8.Introduceclutchcompleteintothe clutchbearing and screwthe latter on
tothescrewdriver.
The hexoftheclutchshaft mustengagewiththehexof the
gear supportresp. spindle(located ingearing).
Checkthisandensure thatengagement lift onthe spindleis
available (onlypush-to-start-screwdriver).
9.Re-adjusttheclutchtothe requiredtorque (seechapter Torque

4.4.Connection-PossibilitiesoftheFunction Control
Use as air pressureoutletduring screw-assembly:
· tocontroldriver start and stop,as well asshut-offcontrol ofclutch;
· ascycle counterof the completeprocess;
eachin connectionwithaPE-Switchorsimilar
Thisfunctioncontrolisunderpressureof appx. 2barduringactualscrew-
driving. Afterreaching thepresettorque,theclutchwill disengage andturnoff
the Screwdriver. The pressure inthe function controllinewill drop. The
Screwdriver can nowbe lifted offtheassembled screw.
Use as air pressureinlet:
· If6.3bar(90PSI)air pressure isgiven tothefunctioncontrol port, the
driver starts rotatingatabout15 %ofitsspeed. This will simplifythe enga-
gementofbit/sockettofastener (forexample when driving hexscrews,
nuts, etc.)
Ifthefunctioncontrol is notneeded,theport hastobeclosed,
otherwisethereis aloss ofpower ofabout 15%.
