Warnings

Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. Refer back to these warnings. Additional, productspecific warnings may be found throughout the body of this manual where applicable.

WARNING

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode.

To help prevent fire and explosion:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).

• Keep work area free of debris, including solvent, rags and gasoline.

• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.

• Ground all equipment in the work area. See Grounding instructions.

• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

PRESSURIZED EQUIPMENT HAZARD

Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury.

• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals.

• Use fluids and solvents that are compatible with equipment wetted parts. See

Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings.

• Check equipment daily. Repair or replace worn or damaged parts immediately.

• Do not alter or modify equipment.

• Use equipment only for its intended purpose. Call your Graco distributor for information.

• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

• Do not kink or overbend hoses or use hoses to pull equipment.

• Keep children and animals away from work area.

• Comply with all applicable safety regulations.

WARNING

PERSONAL PROTECTIVE EQUIPMENT

You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing loss. This equipment includes but is not limited to:

• Protective eyewear

• Clothing and respirator as recommended by the fluid and solvent manufacturer

• Gloves

• Hearing protection

Operation

4

• Check that your shop air provides adequate air flow.

• Use a minimum 3/8 in. (10 mm) ID air hose.

• Set shop air pressure regulator (not supplied) according to paint manufacturer’s recommendation. See maximum pressures and compliant

air pressures on page 2.

• Make sure no air restrictions, such as low-volume cheater-valves, obstruct the air flow. If an air adjusting valve is desired, use a Graco Air Adjusting

Valve (288744, 234387) or Digi-tell

(288652).

• Install a shutoff valve (not supplied) downstream of the air regulator to shut off gun air.

• Install an inline air filter (not supplied) to clean and dry the gun air supply.

1. Shut off the air supply.

2. Connect a clean, dry, filtered air supply to

the air inlet fitting (25). See page 10.

3. If this is the first time using the equipment, flush the gun. See page 5.

Pressure Relief Procedure

1. Turn off the gun air supply.

2. Trigger the gun to relieve pressure.

Spraying

CAUTION

Excessive atomizing air pressure can increase over-spray, reduce transfer efficiency, and result in a poor quality finish.

Regulatory agencies in certain states prohibit the operation of a spray gun above

10 psi (69 kPa, 0.7 bar) atomizing air cap pressure.

1. Fill the cup with material. Do not fill past the shoulder on cup.

2. Turn on the shop air to the gun and set atomizing pressure with the gun fully triggered.

3. Adjust the pattern size and shape with the fluid adjust knob (8). Fluid adjust knob (8) is factory set for maximum needle trigger travel and material flow. Turn knob clockwise to reduce pattern size/ fluid flow and counterclockwise to increase it.

See Troubleshooting, page 7, if you expe-

rience an irregular pattern.

312106D

Maintenance

Volatile Organic Compounds

(VOC) Regulation

In certain states, spraying solvents that release

VOCs into the atmosphere when cleaning a spray gun is prohibited. To comply with these air quality laws, you must use a cleaning method that prevents the escape of VOC vapors into the atmosphere. See Compliant

.

Cleaning Methods, page 5

Clean air line filters as directed by the manufacturer.

Maintenance

Cleaning Gun and Cup

CAUTION

• Do not submerge gun in solvent. Solvent dissolves lubricant, dries out packings, and clogs air passages.

• Do not use metal tools to clean air cap holes as this may scratch them and distort the spray pattern.

• Use a compatible solvent.

1. Flush, page 5.

2. Use a rag moistened in solvent to wipe outside of gun and cup.

3. Make sure cup lid vent hole is clear.

4. Blow dry gun inside and out. Lubricate, see

Maintenance, page 5.

• Frequently lubricate the gun moving parts with a drop of non-silicone oil.

• Do not disassemble the spray gun if you are having a spray pattern problem. See

Troubleshooting, page 7, for information

on how to correct the problem.

• Check for fluid leakage. Tighten fittings or replace equipment as needed.

Flush

Flush before using the equipment, before changing colors, and when you are done spraying. Use solvent that is compatible with gun wetted parts and fluid that will be sprayed.

See Compliant Cleaning Methods, page 5, to comply with air quality laws if applicable.

1. Relieve pressure, page 4.

2. Dispose of any paint in the cup.

3. Fill the cup with a small amount of solvent.

4. Spray into a grounded metal waste container until the equipment is clean.

5. Relieve pressure, page 4.

See Compliant Cleaning Methods, page 5, to comply with air quality laws if applicable.

Cleaning Nozzle and Air Cap

1. Remove air cap (13), trigger gun, remove nozzle (11), and soak both in a compatible cleaning solution.

2. Clean them and the front of the gun with a soft-bristle brush dipped into compatible solvent. Do not use a wire brush or metal tools.

3. Use a soft implement, such as a toothpick to clean out air cap holes.

Compliant Cleaning Methods

1. Place spray gun in a gun washer that completely encloses the gun and components during cleaning, rinsing, and draining.

2. Spray solvent through the spray gun into a closed gun cleaning station.

Troubleshooting

Troubleshooting

Problem Cause

Normal pattern.

Solution

No action necessary.

Right

Wrong

Heavy top or bottom pattern

Wrong

Split pattern

Dirty or damaged air cap or fluid nozzle.

Pressure too high for viscosity of material being sprayed.

Rotate air cap 180°.

If pattern follows air cap, problem is in air cap (13). Clean and inspect. If pattern is not corrected, replace air cap.

If pattern does not follow the air cap, the problem is with the fluid nozzle. Clean and inspect the nozzle. If the pattern is not corrected, replace nozzle.

Reduce air pressure and increase material viscosity.

Correct pattern by narrowing fan size with spray width adjustment knob (8).

Dirty or distorted air horn holes.

Clean and inspect air cap. If pattern is not corrected, replace air cap.

Wrong

Gun spitting Air getting into paint stream.

Check if cup is empty and fill.

Tighten fluid nozzle (11).

Check and tighten needle packing nut (17).

Will not spray Cup is empty.

Fluid adjustment knob (8) turned too far clockwise.

Excessive air blowing back

Check fluid nozzle (11) for damage.

Fill cup.

Adjust knob (8) counterclockwise.

Loose fluid nozzle (11).

Tighten fluid nozzle (11).

Damaged fluid nozzle seal (21).

Replace seal (21).
