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 symbol refers to procedure-specific risk. Refer back to these warnings. Additional, product-specific 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 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.

• 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.

Warnings

WARNING

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.

• 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.

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 the Pressure Relief Procedure when you stop spraying and before clean-

ing, checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

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

ately.

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 hydrocar-

bon solvents or fluids containing such solvents.

• Many other fluids may contain chemicals that can react with aluminum. Contact

your material supplier for compatibility.

Warnings

WARNING

TOXIC FLUID OR FUMES HAZARD

Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed.

• Read MSDSs to know the specific hazards of the fluids you are using.

• Store hazardous fluid in approved containers, and dispose of it according to appli-

cable guidelines.

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, hearing loss, inhalation of toxic fumes, and burns. This equipment includes but is not limited to:

• Protective eyewear, and hearing protection.

• Respirators, protective clothing, and gloves as recommended by the fluid and sol-

vent manufacturer.

Gun Selection

HVLP Guns

An HVLP gun is a high transfer efficiency gun that limits the air pressure at the air cap to 10 psi (0.07 MPa, 0.7 bar) maximum. In some areas, an HVLP gun is required for compliance with environmental standards. See the Air Cap chart, page 8, for maximum inlet pressure.

Proper Needle/Nozzle Selection

The spray gun's needle/nozzle kits range in size to provide different fluid flow rates. As a general guideline, use the fluid nozzle that will give the required flow with the needle fully triggered at a fluid pressure of 5–20 psi (0.035–0.14 MPa, 0.35–1.4 bar).

• For low flow rates or light viscosity fluid,

select the smaller nozzle sizes.

• For high flow rates or high viscosity fluid,

select the larger nozzle sizes.

• For abrasive fluids, the gun models with

tungsten carbide needle tip and nozzle are recommended.

LVMP Guns

An LVMP gun is a high transfer efficiency gun that has been tested to have a transfer efficiency greater than or equal to HVLP guns. In addition, the LVMP air cap consumes much less air than the HVLP air cap. Graco LVMP guns have no restrictions on air cap pressures.

Conventional Guns

A conventional gun has excellent atomization and high production rates typically with some reduction in transfer efficiency.

HiTEch Guns

A HiTEch gun is a high transfer efficiency gun with excellent atomization. Graco HiTEch guns have no restrictions on air cap pressures.

Installation

This spray gun can spray most coatings or finishes currently being used for small component plastic, wood and metal finishing applications, while easily operating from paint delivery systems, such as pressure pots or remote pumps for production line operation.

The air regulator must have a minimum air flow capacity of 30 scfm at 100 psi (0.7 MPa,

7.0 bar) air pressure.

Ventilate Spray Booth

To prevent hazardous concentrations of toxic and/or flammable vapors, spray only in a properly ventilated spray booth. Do not operate the spray gun unless ventilation fans are operating.

Configure Gun and Manifold

Guns with Manifold

See FIG. 1. The gun is shipped with a fluid plug (25). To use the gun in a circulating system, do not install the plug. In a non-circulating system, install the plug as shown to minimize flush time.

1. Connect the fluid supply line to one fluid port fitting and the fluid return line to the other. The manifold fluid ports are reversible.

2. Install the gun on the manifold, using the two screws. Torque the screws evenly to 50 in-lb (5.6 N•m).

Do not install when used in circulating systems.

• Check and follow all national, state, and

local codes regarding air exhaust velocity requirements.

• Check and follow all local safety and fire

codes.

Installation

Guns without Manifold

The gun is shipped ready for use in a circulating system, with a fitting installed in each fluid port. Connect the fluid supply line to one fluid inlet fitting (15) and the fluid return line to the other.

To use the gun in a non-circulating system, remove one fitting and replace with plug (33, shipped loose). Use the 3/16 allen wrench supplied to tighten the plug.

Install for use in a non-circulating system.

Use fitting (15) for use in a circulating system.

Pump/Fluid Supply

Ground the pump by connecting a ground wire and clamp between the fluid supply and a true earth ground as instructed in your separate pump instruction manual.

Air Compressors and Hydraulic Power Supplies

Ground the air compressors and hydraulic power supplies according to the manufacturer recommendations.

Spray Gun

Ground the spray gun by mounting the manifold to a properly grounded reciprocator, robot, or stationary mount. Check the electrical resistance between the manifold and a true earth ground. Resistance must not exceed 1 megohm.

FIG. 2: Guns without Manifold

Ground System

The following grounding instructions are minimum requirements for a system. Your system may include other equipment or objects that must be grounded. Check your local electrical code for detailed grounding instructions for your area and type of equipment. Your system must be connected to a true earth ground.

Fluid Supply Container

Ground the fluid supply container according to local code.

Object Being Sprayed

Ground the object that is being sprayed according to local code.

Solvent Pails

Ground all solvent pails that are used when flushing according to local code. Use only conductive metal pails placed on a grounded surface. Do not place the pail on a non-conductive surface, such as paper or cardboard, which interrupts the grounding continuity.
