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. 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.

SKIN INJECTION HAZARD

High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.

• Do not spray without tip guard and trigger guard installed.

•Engage trigger lock when not spraying.

•Do not point gun at anyone or at any part of the body.

• Do not put your hand over the spray tip.

•Do not stop or deflect leaks with your hand, body, glove, or rag.

•Follow the Pressure Relief Procedure when you stop spraying and before cleaning,

checking, or servicing equipment.

•Tighten all fluid connections before operating the equipment.

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

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. Paint or solvent flowing through the equipment can cause static sparking. 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 sparking).

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

•Never spray or flush solvent at high pressure.

•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.

•Use only grounded hoses.

•Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless they are anti-static 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.

Warnings

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Always wear appropriate gloves, eye protection, and a respirator or mask when painting.

• Do not operate or spray near children. Keep children away from equipment at all times.

•Do not overreach or stand on an unstable support. Keep effective footing and balance at all times.

•Stay alert and watch what you are doing.

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

•Do not kink or over-bend the hose.

•Do not expose the hose to temperatures or to pressures in excess of those specified by Graco.

•Do not use the hose as a strength member to pull or lift the equipment.

•Do not spray with a hose shorter than 25 feet.

•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.

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.

•Do not use chlorine bleach.

•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.

•Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.

Setup

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection or splashed fluid, follow the Pressure Relief Procedure whenever sprayer is stopped and before sprayer is cleaned or checked, and before equipment is serviced.

1.Turn sprayer OFF.

2.Engage the trigger lock. Always engage the trigger lock when sprayer is stopped to prevent the gun from being triggered accidentally.

3.Turn pressure control knob to lowest setting.

4.Put drain tube into a waste pail and turn Prime/Spray valve in PRIME position (drain) to relieve pressure.

5.Hold the gun firmly to a pail. Point gun into pail. Disengage the trigger lock and trigger the gun to relieve pressure.

6.Engage the trigger lock.

7.If you suspect the spray tip or hose is clogged or that pressure has not been fully relieved:

a.VERY SLOWLY loosen the tip guard retaining nut or the hose end coupling to relieve pressure gradually.

b.Loosen the nut or coupling completely.

c.Clear airless hose or spray tip obstruction. See Clear Spray Tip Clog, page 8.

Gun Trigger Lock

To prevent injury when the gun is not in use, always engage the gun’s trigger lock if unit is being shut down or left unattended.
