1.1.GeneralSafetyTips
Beforeoperating tool makesureto carefullyreadand
observethisoperating instruction.
Generally,theoperator ofthe equipmentand/ormachineryisresponsible for
the equipment’sperfect condition and operation,while observing all necessary
safetyregulations.The equipmentand/or machineryhasbeen constructed in
accordancewiththe newestlevel oftechnologywhile recognizingall
necessarysafety-related requirements.Nevertheless,while operating the
equipmentand/or machinerythereisariskofbodilyharmtothe operator as
well as damagetoequipmentand/or machineryand other property.
Operatethe equipment and/ormachineryonlyif equipment/machinery
· Isused forthe task it was designed for
· is inperfectworkingcondition andsafetouse.
It isimportanttoobservethe technical dataofthe equipment, especiallyin
regardstotheenvironmental temperatures. The designated area ofuseforthis
equipmentisclearlydescribed in chapter Designated EquipmentUse and
thoserequirementshavetobe observed aswell.Prerequisiteforthe safe
conduct andthe uninterrupted operationofthe equipment, isthe knowledge of
the basicsafetytipsandthesafetyregulations.Additionally,all current
regulationsforasafeoperational area,for accident-prevention guidelinesof
electrical and mechanical installations, aswell asnoisesuppression
requirementsmust be observed.During anymaintenanceor repair work,a
clean worksurfaceisrecommended.Also,itisnotrecommended toeither eat
or smokeduring repair or maintenance.Arbitrarychangesmadetothe
equipment,whichaltersitsdesignated use,voidsthe warrantyand cancelsthe
manufacturersliability.
· The toolis notinsulated toprotectagainstanelectricalpower surge.
· Itisnotrecommended tousethistoolin explosivehazardous
environments,unlessit wasspecificallydesigned forsuchause.
The operating instruction booklet,especiallythe safetysymbolsandsafetytips
attachedtothe equipmentor included inthe documentation,mustbeobserved
at alltimesbyall persons gettingintocontact withtheequipment.

1.2.GeneralSafetyTipsforPneumaticScrewdriverSpindles
·
Disconnectthetoolfromthe airsupply, when changingbits or
when readjusting clutch.
· Donotwear wide clothingorjewelry, fortheycan beseizedby
movable parts.Wear ahairnet ifoperator haslonghair.
· Keep handsoff theinstalledbitorsocket.
· Injuryispossible,if the driver reacts withan unexpectedmotionor when
driver is usedwithabrokenbit.
· Keep handsawayfromholdingfixture (ifused).Thisapplies especiallywhen
looseningscrews inatight area.Thereis arisk ofsqueezing fingers b
etween
holding bracket and tool.Makesurethat anybracketusedis correctly
installed.
· An unexpectedmotion ofthebitorsocketmaycreateadangerous situation.
· Especially, when operatinganimpact wrench, it ispossiblethatan injury
occurs, ifthebitbreaks [flying splinters].
· Whenusing toolwithbit-adapter or bit-extension (i.e. Magnetic Bitholder),
makesure,thatthoseitems areingoodcondition andwell suitedfor the
applicationwiththistool.
· Whenusing ascrewdriver stand, makesure thatthetoolis
securelymounted.If nostandisused, makesuretohaveasolid
stancetoabsorbthetools’torquereaction force.
· Ifyou are notabletoabsorbthetorquereactionforce,usea
holding fixture orside handleonthe screwdriver.
· Afterturning-offthetool,thebit will continuetorotate[inertia].
· Donotexceed themaximumallowableairpressure.Apressure regulator
hastobeinstalled, whichregulatestheairpressurebeforeitreachesthe
tool.
· Avoid pressure tofall belowtheminimumallowable airpressure,because
the clutchcannotshut-offsafely. Thismaycausean increasedtorque
reaction force, resultingin riskstooperator,toolor product.
· Incaseofan interruptionof the air supply, makesuretowait untiltoolhas
cometoastand still, prior toreactivatingtool.

·
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%

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 installed on theclutch.Adjustclutchtothe required
torquevalue.Ifnecessary, exchange clutchspring.The required torque
adjustment can bechecked,using aDEPRAG TorqueWrenchor Measuring
Platform(seeDEPRAG catalogsD3020 andD3022).This equipment can
alsobe usedtore-adjustthetorque oftheScrewdriver.
Tooperatetheclutch,usingaclutchspring whicheither
surpassesorfallsbelowitsspecifiedtorque range,leadstoa
reductionofthe torque accuracy.
Push–to–start-screwdriver!
The flowpressure should notdropbelow5bar (71PSI)–reduced output!
NOTICE
The screwdriver isfurnishedwitha reversiblemotor and a
clutchtorquing outin right-hand rotation (sothatifyou look

5Handling
The operationof theDEPRAGMINIMAT-Screwdriverisverysimple. Gripthe
Screwdriverasillustratedon the picture“Connection of aDEPRAGMINIMAT-
Screwdriver”.
Assoonas you putthebit ontothe screwand slightlypushthescrewdriver
down, it will startrunning.Afterreachingthepresettorque,theautomatic
clutchwill disengageandturnoff the Screwdriver. The Screwdriver will be
readyfor thenext operationafterliftingitoffthescrew.
Althoughthe reactiontorque you will noticeisratherlowduetothe
ergonomicallyshaped handleandthe immediateeffect of the torque-out clutch,
wehighlyrecommend touseanadditionaltorquesupport, if torque ishigher
than 5Nm(suchasalinearstandorlateralhandleasperbrochureD3340 E).
The operatingdirection of reversibleScrewdrivermodelscanbe reversed by
actuating thereversebutton, inordertoloosen tightened screws. Toolwill also
start afterpushing itdown. Theclutchwillbe locked inthereversedirection. An
increased reactiontorque mayoccurinthe caseof screwsarehardtotighten
(suchasscrewswithdefectivethread).The reversebuttoncanbe lockedby
turning.
