Repair or replace worn or damaged Parts not exceed the maximum working pressure of the lowest rated system component. Refer totheTechnical Dataon page 15 for the maximum working pressure of this not move or lift pressurized fluids or solvents which are compatible with equipment wetted Parts . Refer to theTechnicalDatasection on page 15 and all equipment manuals. Read the fluid and solvent manufacturer not use 1,1,1--trichloroethane, methylene chloride, other halogenated hydrocarbon solvents orfluids containing such solvents in pressurized aluminum equipment. Such use could result in achemical reaction, with the possibility of hoses must have spring guards on both ends to protect them from rupture caused by kinksor bends at or close to the with all applicable local, state and national fire, electrical and other safety FLUID HAZARDI mproper handling of hazardous fluids or inhaling toxic fumes can cause extremely serious injury,even death, due to splashing in the eyes, ingestion, or bodily the specific hazards of the fluid you are hazardous fluid in an approved container.

5 Dispose hazardous fluid according to all local,state and national appropriate clothing, gloves, eyewear and HAZARDDue to the high pressure fluid emitted, a strong recoil action may occur when you trigger this gun. Ifyou are unprepared, your hand could be forced back toward your body or you could lose your bal-ance and fall, resulting in serious RequirementsWARNINGKeep the wallet-sized warning card provided withthis gun with the operator at all times. The cardcontains important treatment information should aninjection injury occur. Additional cards are availableat no charge from Graco The pressure drain valve assists in relieving fluidpressure in the displacement pump, hose and gun;triggering the gun to relieve pressure may not Strain the fluid you are spraying if it containsparticles which could clog the spray the SystemWARNINGTo reduce the risk of static sparking, ground thepump and all other equipment used or located inthe spray area.

6 Check your local electrical code fordetailed grounding Instructions for your area andtype of equipment. Also follow the groundinginstructions provided in your pump or sprayermanual. The gun obtains grounding through con-nection to a properly grounded fluid hose and pumpor sprayer. Also readFIRE OR EXPLOSION HAZ-ARDon page to Use the Gun Trigger Safety1. To lock the gun trigger safety, turn the safety to aright angle with the gun body. See Fig. To unlock the gun trigger safety, push the safetyout and turn it parallel with the gun Fig. Relief ProcedureTo reduce the risk of serious injury, including fluidinjection, splashing fluid or solvent in the eyes oron the skin, follow this procedure when you areinstructed to relieve pressure, when you stopspraying, shut off the pump, check or service anysystemequipment, or install,clean or change Lock the gun trigger Shut off the power to the Unlock the gun trigger Hold a metal part of the gun firmly to a groundedmetal pail.

7 Trigger the gun to relieve Lock the gun trigger Open the drain valve, having a container ready tocatch the drainage. Observe the pressure gauge reads 0 psi/bar when fully the drain valve open until you are ready tospray you suspect that the spray tip or hose is completelyclogged or that pressure has not been fully relieved,very slowly loosen the tip guard retaining nut or hoseend coupling and relieve pressure gradually. Clean thetip or hose 112 Gun trigger safety shown lockedGun trigger safety shown unlocked12039663084916 Installation/OperationHow to Operate the GunWARNINGTo reduce the risk of component rupture, and seri-ous injury, including fluid injection, do not exceedthe gun s4000 psi (276 bar, MPa) MaximumWorking Pressureor the maximum working pres-sure of lowest rated component in the 2308A1. Connect an electrically conductive fluid hose (A) tothe gun inlet.

8 See Fig. With no tip installed, start the pump. Flush thepump according to the Instructions supplied with the lowest pressure possible. Prime thesystem with the Relieve Install the SwitchTip (8) and tip guard (30). Followthe i nstructions in the manual, Fig. Start the pump. Trigger the gun onto test the fluid pressure until the spray iscompletely atomized. Use the lowest pressurenecessary to get the desired results. Higher pres-sure may not improve the spray pattern and willcause premature tip and pump If adjusting the pressure does not give a goodspray pattern, relieve pressure and then tryanother tip Use a full-open, full-close trigger action. Hold thegun about 14 in. (350 mm) from and at right anglesto the work surface. Don t swing the gun in an to find the best length and speed to Adjust the Spray Pattern1.

9 To adjust the spray pattern direction, relieve pres-sure. Loosen the tip guard retaining nut (B). Turnthe tip guard/tip groove horizontally (C) for a hori-zontal pattern and vertically (A) for a verticalpattern. Tighten the nut. See Fig. The spray tip orifice and spray angle determinesthe coverage and size of pattern. When morecoverage is needed, use a larger spray tip ratherthan increasing fluid in the tip guard reduce paint buildup onthe guard while spraying. Damage to the sharpedges of the openings causes paint to collect atthat area.
