6. AIR SUPPLY
6.1.  Recommendedhook-upg.2
6.1.1. Ensurespraygunairvalve(ortrigger)isintheo󰀨positionbeforeconnectingtotheairsupply.
6.1.2. Youwillrequireanairpressureof1.5to2bar(21-30psi),andanairowaccordingtospecication.
WARNING!Ensuretheairsupplyiscleananddoesnotexceed2bar(30psi)whileoperatingthespraygun.Toohighanair 
 pressureand/oruncleanairwillshortentheproductlifeduetoexcessivewear,andmaybedangerouscausingdamageand/or 
 personalinjury.
6.1.3. Draintheairtankdaily.Waterintheairlinewillruinthepaintnishanddamagethespraygun.
6.1.4. Cleanairinletlterweekly.
6.1.5. Linepressureshouldbeincreasedtocompensateforunusuallylongairhoses(over8metres).Theminimumhosediametershould
 be1/4”I.D.andttingsmusthavethesameinsidedimensions.
6.1.6. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.
6.2. COUPLINGS
 Vibrationmaycausefailureifaquickchangecouplingisconnecteddirectlytothespraygun.Toovercomethis,connectaleader
hose to the spray gun. A quick change coupling may then be used to connect the leader hose to the air line recoil hose
(g.2and3).
7. OPERATION
7.1. For best results, the gun should be held perpendicular to the surface being sprayed and moved parallel to it. Start the stroke
 beforesqueezingthetriggerandreleasethetriggerbeforenishingthestroke.Thiswillenableaccuratecontrolofthe  
gun and material (g.3B).
7.2.  Sprayfromadistanceofabout3.9to5.9inches(100to150mm)dependingonthematerial
 andtheatomizingpressure.Thematerialdepositedshouldalwaysbeevenandwet.Each
 strokemustoverlaptheprecedingstroketoobtainauniformnish.Toreduceover-spray
 andobtainmaximume󰀩ciency,spraywiththelowestpossibleatomizingairpressure.
7.3.  Controllingthefansprayandtheuid.
 a)Usetheneedle(paint)adjustmentknob(g.4.2)toadjusttheamountofpaintow.
 b)Theatomizingairowiscontrolledbythecontrolknob(g.4.1).
 c)Thevolumeofairinputiscontrolledbytheadjustmentknob(g.4.3).
d) As width of spray is increased more material must pass through the gun to obtain the
same coverage on the increased area.
 e)Turntheairnozzle(g.4.4)toachieveahorizontalorverticalfanspray.Lockthenozzle
 withretainingring(g.4.5).Thespraypatternofthegunisvariablefromroundtoatwithall
 patternsinbetween.Innormaloperation,thewingsonthenozzlearehorizontal(g.5).This
provides a vertical fan-shaped pattern which gives maximum, uniform and even coverage
 whenmovingthegunbackandforth,paralleltotheworksurface(g.6).

FOR OPTIMUM PERFORMANCE IT IS VERY IMPORTANT TO ENSURE THE SPRAY GUN IS CORRECTLY CLEANED AFTER EACH USE.
Disconnect from the air supply before attempting any cleaning or maintenance.
8.1. CLEANING THE GUN

8.1.4. Wipe the outside of the gun with a dampened solvent rag.
8.1.5. Ifthereisaneedtoprobetheholesinthenozzles,ensureatoolthatissofterthanbrassisutilised,undernocircumstancesusea
 metaltool,astheslightestamountofdamagewilladverselya󰀨ectthespraypattern.
8.1.6. Adjusttheuidneedlevalvesothatwhenthegunistriggered,airowoccursbeforeuidow.
9. MAINTENANCE
9.1.1. Takecarewhenre-assembling.Screwpartshandtighttoavoidcross-threading.Ifapartcannoteasilybeturnedbyhand,check
that it is the correct part, or unscrew it, realign and retry. DO NOT use excessive force when re-assembling.
9.1.2. Whenchangingthenozzlesize,ensurethecompletenozzlesetistted.Thisconsistsofaircap,uidnozzleandpaintneedle. 
 Inserttheuidnozzlebeforepaintneedle.
10. TROUBLESHOOTING
Afaultysprayisusuallycausedbyimpropercleaningordriedmaterialaroundtheuidnozzletiporintheairnozzle.Ifcleaningis
required,removethesepartsandsoaktheminsolvent.Thiswillsoftenthedriedmaterialwhichcanthenberemovedwithabrushoracloth.
Thesepartsarecarefullymachinedandanydamagetothemwillcauseafaultyspray.Ifeithertheairnozzleoruidnozzlearedamaged,they
must be replaced before a perfect spray can be obtained.
Problem Possible Causes Solution
Dried material in a side port restricts passage of air.
Greaterflowofairfromthecleansideportforcesa
fan pattern in the direction of the clogged side.
Dissolve material in the side ports with solvent, then
blow the gun clean. DO NOTpokeintothenozzles
with metal instruments.
Driedmaterialaroundtheoutsideofthefluidnozzle
tiprestrictsthepassageofatomizingairatonepoint
throughthecentreopeningoftheairnozzleand
resultsinthepatternshown.Thispatterncanalso
becausedbyalooseairnozzle.
Removetheairnozzleandwipeofffluidtipusinga
ragdampenedwithsolvent.Tightentheairnozzle.
Materialtoothinoratomizationairpressuretoohigh. Regulate material viscosity or reduce air pressure.
Paintsprayutter
Not enough paint in bottle.
Nozzleset/seatingdirty,damagedorloosely
installed.
Refillbottle.Removethefluidnozzle,cleantheback
ofthenozzleandthenozzleseatusingacloth
dampenedwiththinner.Refitthenozzleandsecure
it tightly against the body.
Ifnecessaryreplacenozzleset.
Materialbubblesor“boils”inpaintcup.
Atomised air flowing through the paint channel to the
bottle.Thepaintnozzleisnotsufficientlytight.
Airnozzleisnotcompletelyscrewedon.
Tighten,cleanorreplacepartsaccordingly.
