In someareas, an HVLP gun is required for compliancewith environmental standards.6312414T
SetupSetup5. Connect a fluid hose to the fluid inlet fitting.See FIG. 1.At least one hose must provide a staticground to the gun.Connect Air and Fluid Lines1. Shut off the air supply.2. Install a shutoff valve (not supplied) downstream of the air regulator to shut off gunair.3. Install an inline air filter (not supplied) toclean and dry the gun air supply.4. Connect a clean, dry, filtered air supply tothe air inlet fitting. See FIG. 1.air inletFIG. 1fluid inletti11094a6. Connect other end of the fluid hose to aregulated fluid supply line.Ground the Gun Recommended 5/16 in. (7.9 mm) IDhose, optional 3/8 in. (9.5 mm) ID hose. Check that your shop air provides adequate air flow. See Technical Data,page 23, for minimum cfmrequirements. Set shop air pressure regulator (notsupplied) according to fluid manufacturer’s recommendation. See maximumcompliant air pressure on air cap. 312414TMake sure no air restrictions, such aslow-volume cheater valves, obstructthe air flow.Check your local electrical code and pumpmanual for detailed grounding instructions.Ground the spray gun through connection to aGraco-approved grounded fluid or air supplyhose.Flush Before Using EquipmentThe equipment was tested with lightweight oil,which is left in the fluid passages to protectparts. To avoid contaminating your fluid withoil, flush the equipment with a compatible solvent before using the equipment. See Flush,page 10.7
SetupAdjust Spray Pattern1. Rotate the air cap to achieve desired spraypattern. See FIG. 2.7. To reduce fluid flow, turn the fluid controlvalve clockwise. ti4839aFIG. 2If the fluid control valve is turned clockwise all the way, the gun will emit onlyair.If you cannot achieve the correct fluidflow with the fluid control valve, a different sized nozzle may be necessary.For smaller fluid flow, use the next sizesmaller nozzle. For a larger fluid flow,use the next size larger nozzle.8. Spray a test pattern. Evaluate the spraypattern size and atomization.2. To achieve full fan pattern, open the aircontrol valve by turning the knob fully counterclockwise. See FIG. 3.9. To achieve a narrow spray pattern, turn aircontrol valve clockwise.3. To create a round pattern, turn the patternair off by turning the air control valve fullyclockwise. See FIG. 3.10. To improve atomization, reduce the fluidflow rate. Increasing the air pressure canimprove atomization but may result in poorTransfer Efficiency (TE) or non-compliantoperation.4. Trigger gun and adjust gun air pressure.Refer to Technical Data, page 23, for inletair pressure recommendations.5. To establish the correct fluid flow, turn thefluid control valve counterclockwise until norestriction of the trigger movement is felt,then turn out another half turn.air control valvefluid control valveair inlet valveti11097aFIG. 36.

OperationOperationNOTE: See Troubleshooting, page 12, if youexperience an irregular pattern.Pressure Relief Procedure1. Turn off air and fluid supply.When using the HVLP spray gun, instead of aconventional airspray gun, you may need touse a slightly slower hand movement andmake fewer passes with the gun to coat a part.This is due to the reduced spray velocity produced by lower HVLP air pressures, along witha larger fluid particle size because there is lessair to blow off solvents than is produced byconventional airspray. Take care to avoid runsor sags as you spray.2. Hold a metal part of the gun firmly to agrounded metal pail. Trigger the gun torelieve pressure.Volatile Organic Compounds(VOC) RegulationTrapped air can cause the pump to cycleunexpectedly, which could result in seriousinjury from splashing or moving parts.Apply FluidNOTICEExcessive atomizing air pressure canincrease overspray, reduce transfer efficiency, and result in a poor quality finish.Regulatory agencies in some states prohibitthe operation of a spray gun above 10 psi(69 kPa, 0.7 bar) atomizing air cap pressure.In certain states, spraying solvents thatrelease VOCs into the atmosphere whencleaning a spray gun is prohibited. To complywith these air quality laws, you must use acleaning method that prevents the escape ofVOC vapors into the atmosphere. See Compliant Cleaning Methods, page 11.1. Turn on shop air and fluid supply to thegun. Set atomizing pressure and fluid pressure with the gun fully triggered.2. Adjust the pattern size and shape. Seepage 8.3. To achieve the best results when applyingfluid: Keep the gun perpendicular and6 to 8 inches (150 to 200 mm) from objectbeing sprayed. Use smooth, parallel strokes across thesurface to be sprayed with 50% overlap.312414T9
Daily Gun MaintenanceDaily Gun MaintenanceFollow Pressure Relief Procedure, page 9,when you stop spraying and before cleaning,checking, servicing, or transporting equipment. Read Warnings, page 5.General Tasks Frequently lubricate the gun moving partswith a drop of non-silicone oil. Do not disassemble the spray gun if youare having a spray pattern problem. SeeTroubleshooting, page 12, for information on how to correct the problem.FlushFlush before changing colors, before fluid candry in the equipment, at the end of the day,before storing, and before repairing equipment. Flush at the lowest pressure possible.Check connectors for leaks and tighten asnecessary. Flush with a fluid that is compatiblewith the fluid being dispensed and the equipment wetted parts.NOTE: See Compliant Cleaning Methods,page 11, to comply with air quality laws if applicable.1. Follow Pressure Relief Procedure,page 9.2. Disconnect the fluid supply hose and airsupply hose from gun. Follow the Pressure Relief Procedure,page 9.3. Connect the solvent supply hose to thegun. Clean the fluid and air line filters daily.4. Start the pump. Always use the lowest possible fluid pressure when flushing. Check for any fluid leakage from gun andfluid hoses.5. Hold a metal part of the gun firmly to agrounded metal pail. Trigger the gun untilclean solvent dispenses.NOTICESolvent left in gun air passages could resultin a poor quality paint finish. Do not use anycleaning method that may allow solvent intothe gun air passages.6. Turn off solvent supply. 8. Disconnect the solvent supply hose fromthe gun. 10Do not point gun up while cleaning it.Do not wipe gun with a cloth soaked insolvent; wring out the excess.Do not immerse the gun in solvent.7. Follow Pressure Relief Procedure,page 9,312414T
Daily Gun MaintenanceClean GunNOTICE Do not submerge gun in solvent. Solventdissolves lubricant, dries out packings, andclogs air passages. Do not use metal tools to clean air capholes as this may scratch them and distortthe spray pattern. Use a compatible solvent.1. Flush, page 10.2. Remove air cap. Trigger gun, remove nozzle, and soak both in a compatible solution.NOTICETrigger the gun whenever you tighten orremove the nozzle. This keeps the needle tipaway from the nozzle seating surface andprevents the tip from being damaged.3. Dip the end of a soft-bristle brush into acompatible solvent. Do not continuouslysoak the brush's bristles with solvent anddo not use a wire brush.6. Trigger the gun while you install the fluidnozzle with the gun tool. Tighten the nozzlesecurely to 155-165 in-lb (17.5-18.6 N m)to obtain a good seal.7. Install the retaining ring (14) andair cap (13b).8. Dampen a soft cloth with solvent and wringout the excess.

The Truth About Gun Control 3 Introduction Gun control laws have been with us almost as long as guns have existed, long before the founding of the United States, but the term “gun control” is a misnomer. A gun is not a sentient being—it is a tool. Gun control laws, in reality, are systems for controlling people.
While gun cleaning and care are essential to keeping your firearm in good working order, learning and practicing the rules of safe gun handling is the top priority for all gun owners. Firearm safety applies at all times, including when cleaning your gun. RULE NO. 1 ALWAYS KEEP YOUR GUN POINTED IN A SAFE DIRECTION.
Gun with user notification Publication Number: US20050066567A1 Abstract: A gun is disclosed having conventional components and a holster. The gun has means for detecting removal of the gun from the holster, means for processing the output of the detection means, and means for authenticating the user of the gun.
