The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear 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.

• Do not fill fuel tank while engine is running or hot; shut off engine and let it cool. Fuel is flammable and can ignite or explode if spilled on hot surface.

• 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 power or light switches on or off when flammable fumes are present.

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

• Use only grounded hoses.

• Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless they are antistatic or conductive.

• Stop operation immediately if static sparking occurs or you feel a shock .

Do not use equipment until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not operate the unit when fatigued or under the influence of drugs or alcohol.

• 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. For complete information about your material, request MSDS from distributor or retailer.

• Do not leave the work area while equipment is energized or under pressure.

• Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only.

• Do not alter or modify equipment. Alterations or modifications may void agency approvals and create safety hazards.

• Make sure all equipment is rated and approved for the environment in which you are using it.

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

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

• Do not kink or over bend hoses or use hoses to pull equipment.

• Keep children and animals away from work area.

• Comply with all applicable safety regulations.

WARNING

PRESSURIZED ALUMINUM PARTS HAZARD

Use of fluids that are incompatible with aluminum in pressurized equipment can cause serious chemical reaction and equipment rupture. Failure to follow this warning can result in death, serious injury, or property damage.

• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents.

• Many other fluids may contain chemicals that can react with aluminum. Contact your material supplier for compatibility.

PERSONAL PROTECTIVE EQUIPMENT

Wear appropriate protective equipment when in the work area to help prevent serious injury, including eye injury, hearing loss, inhalation of toxic fumes, and burns. This protective equipment includes but is not limited to:

• Protective eyewear, and hearing protection.

Troubleshooting

Troubleshooting

1. Follow Pressure Relief Procedure , page 5, before

checking or repairing gun.

2. Check all possible problems and causes before disassembling gun.

Problem

Orange peel finish - Paint surface not smooth

Blushing - clear coatings appear milky

Fish eyes - small pools on painted surface that will not fill

Runs and sags

Solvent pops or bubbles

Cause

Pain droplets too large

Paint droplets drying too fast to properly flow out of gun

Cold weather spraying

Moisture condensation is trapped in lacquer when spraying in hot, humid conditions

Silicone contamination from lubricants, grease, polish, or waxes on the surface being sprayed

Applying too much paint per pass for the drying conditions

Sprayed surface drying before solvent gas can be released

Solution

• Maintain proper spraying distance, page 6.

• Keep turbine air filters clean to allow full air flow.

• Do not use an air hose that is too long to provide sufficient atomization pressure.

• If droplets are still too large, reduce fluid.

Keep object being sprayed out of direct sunlight.

When spraying in warmer temperatures, use a slower evaporating solvent or a reducer.

Keep fluid and object being sprayed as close to room temperature as possible. When spraying on a cold surface, most paints will become too thick to flow properly.

• Allow turbine to warm up a few minutes before spraying.

• Store lacquer off concrete floors, at room temperature.

• Apply lighter coats and allow for proper drying time.

• Use a slower evaporating solvent or reducer.

• Do not spray in windy conditions.

Clean all parts with a cleaning solvent; wipe with a solvent rag and a clean rag. Replace rags as needed. If problem persists, use a fish eye eliminator.

• Move gun faster or decrease fluid flow.

• Maintain proper spraying distance, page 6.

• Reduce amount of thinner or use a faster drying thinner.

• Apply fluid in lighter coats to allow for proper evaporation.

• Use the recommended thinners.

• Follow the solutions for Orange Peel Finish,

Paint Droplets Too Large in this Troubleshooting Table.

313754D 9

Troubleshooting

Problem

No or slow fluid flow, intermittent spray, or fluttering spray

Cause

Wrong size fluid set being used

Gun fluid nozzle blocked by dried paint or damaged

Cup or pressure pot cover not tight enough or gasket damaged

Cup or pressure pot fluid tubes blocked by dried paint or damaged

Air flow to cup blocked

Fluid leaks at fluid nozzle after trigger is released

Poor spray pattern

Solution

Select proper fluid set for fluid being sprayed,

page 8

Clean or replace fluid nozzle

Tighten cover or replace gasket

Clean or replace fluid tubes

Needle packings not properly adjusted.

Note: Fluid loss through packings affects fluid pressure and causes a fluid leak from gun body.

Plugged inlet strainer

To check, remove cup (leave cover connected).

Trigger gun and check air flow out of check valve. If air is not flowing freely, clean or replace check valve.

Clean gun body with solvent and brush provided. Adjust needle packings.

Needle not seating in fluid nozzle

Air cap horn hole and/or fluid nozzle plugged

Replace strainer if plugged or remove strainer if material is high viscous.

Check for a loose fluid nozzle or a bent nozzle or needle; tighten nozzle or replace parts as needed.

Soak air cap and/or fluid nozzle in solvent.

Clean air cap horn holes with non-metallic item to avoid permanently damaging them.
