ATTENTION!PLEASEREADTHISMANUALBEFOREUSINGTHESPRAYGUN(TOOL).
IMPROPEROFUSETOOLMAYCAUSEINJURYAND/ORPROPERTYDAMAGE!
ONLY QUALIFIED AND SPECIALLY TRAINED PERSONNEL FAMILIED WITH THESE INSTRUCTIONS IS ALLOWED TO USE AND
MAINTENANCEOFTHETOOL.
Thismanualcontainsdescription,safetyrulesandalltheinformationnecessaryforthecorrectuseofthespraygun.
Thesafetyadvicegiveninthismanualisinadditiontoanddoesnotreplacethegeneralsafetyregulationsapplicableinthe
regionwherethetoolisused.

 Sprayedmaterials(paints,solvents,etc.)canbeharmfultohealth. Alwaysreadalllabels,safetydatasheets
andfollowalltherecommendationsforthematerialbeforespraying.Incaseofdoubts,contactyourmaterial
supplier.Theuseofrespiratoryprotectiveequipmentisalwaysrecommended.
 Alwaysweareyeprotectionwhensprayingorcleaningthespraygun.
 Glovesmustbewornduringsprayingorcleaningtheequipment.
 Staticelectricitycanbegeneratedbyfluidand/orairpassingthroughhoses,bythesprayingprocessandby
cleaningnon‐conductivepartswithcloths.Topreventignitionsourcesfromstaticdischarges,earthcontinuity
mustbemaintainedtothespraygunandothermetallicequipmentused.Itisessentialtouseconductiveair
and/orfluidhoses.
 Sparks,openflamesorhotsurfacescancreateafireorexplosion.

GENERALRULESOFOPERATION
 Whenworkingwiththetoolalwaysusepersonalprotectiveequipmentappropriateforthetypeofworkperformed(goggles,
impactresistantglasses,handprotection,body,etc.);
 Theemployee'sappearancemustcomplywithsafetyrequirements;
 Usespraygunonlyforitsintendedpurpose;
 Observegroundingrulesintheworkplace;
 Toensuremaximumperformanceanddurabilityofthetool,theworkingpressureofthecompressedairmustmatchthe
spraytechnology;
 Highnoiselevelscancausehearingloss.Timelymaintenancewillhelptoavoidnoiselevelsincrease;
 Theflowofcompressedaircancauseseriousinjury.Neverdirectairflowtowardsyourselforothers.Donotusecompressed
airtocleanclothes;
 Beforestartingwork,checkthecompressedairsupplyhosefordamage,wearorotherdefects.Replaceimmediatelyiffound;
 Checkscrewconnectionsbeforestartingwork.Tightenifnecessary;
 Donotcarrythetoolbythecompressedairsupplyhose;
 Alwaysdisconnectthetoolfromthecompressedairlinebeforeperformingmaintenance;
 Usematerialsandsolventsthatarecompatiblewiththespraygunparts.Donotusesolventsorproductscontainingacids;
 Avoidprolongedexposuretosolventsonnon‐metallicpartsofthespraygun.
 Flushspraygunbeforestartinguse,beforechangingmaterialsandattheendofwork.Donotusemethylenechloride1,1,1‐
trichloroethaneforflushing.Thesesolventscanchemicallyreactwithaluminumgunparts.

PURPOSE
Pneumaticgravityspraygunisdesignedtoapplyliquidandlow‐viscositymaterials(varnishes,enamels,primers,etc.)tothe
surfacetobetreatedmanually,bypneumaticspraying.
Thesespraygunsaresuitableforusewithbothwaterandsolventbasedcoatingmaterials.Thesegunsarenotdesignedforuse
withhighlycorrosiveand/orabrasivematerialsand ifusedwithsuchmaterialsitmustbeexpectedthattheneedforparts
cleaningand/orreplacementwillbeincreased.Ifthereisanydoubtregardingthesuitabilityofaspecificmaterial,contactyour
ONETECHDistributororONETECHteamdirectly.
OPERATINGPRINCIPLE
 Theairflowrequiredforsprayingissuppliedtothespraygunthroughasuitableairinletconnection.
 Whenyoupressthetrigger,theairflow,passingthroughthecorrespondingchannelsinthespraygunbody,exitsthrough
theholesintheaircap.
 Whenexitingthroughtheholesintheaircap,theairstreammixeswiththesprayedmaterial,andtheadditionaldirectional
flowbreaksthematerialintosmalldropletsandformsapaintspray.
MAINTENANCE
 Tocleanaircapandfluidnozzle,brushexteriorwithastiffbristlebrush.Ifnecessarytocleancapholes,useabroomstraw
ortoothpickifpossible.Ifawireorhardinstrumentisused,extremecaremustbeusedtopreventholesscratchingorburring,
whichmaycauseadistortedspraypattern.
 Tocleanfluidpassages,removeexcessmaterialfromcup,thenflushwithsolvent.Wipethegunexteriorwithadampened
cloth.Nevercompletelyimmersethetoolintoanysolventorcleaningsolutions,asthisisdetrimentaltothelubricantsandspray
gunlife.
STORAGE
 Avoidstoringtheinstrumentinhighhumidity conditions.
 Lubricatethetoolbeforelong‐termstorage(seeMAINTENANCE).
DISPOSAL
 When disposing of the tool or individual components, observe the local regulations in force in the region where the
equipmentisused.
THEAIRSUPPLYSYSTEM
 Alwaysuseclean,dryair.
 RecommendeddiameterofthecompressedairhoseIDØ3/8"(≈9mm).
 Maintainthenecessarysupplyofcompressedairintheairlinefortrouble‐freeandoptimaltoolperformance.
