WARNING

SKIN INJECTION HAZARD

Spray from the gun, leaks or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin can also cause serious injury.

D Fluid injected into the skin may look like just a cut, but it is a serious injury. Get immediate surgi-

cal treatment.

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

D Do not put hand or fingers over the spray tip.

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

D Do not “blow back” fluid; this is not an air spray system.

D Always have the tip guard and the trigger guard on the spray gun when spraying.

D Check the gun diffuser operation weekly. Refer to the gun manual.

D Be sure the gun trigger safety operates before spraying the gun.

D Lock the gun trigger safety when you stop spraying.

D Follow the Pressure Relief Procedure on page 5 if the spray tip clogs and before cleaning,

checking or servicing the equipment.

D Tighten all fluid connections before each use.

D Check the hoses, tubes and couplings daily. Replace worn or damaged parts immediately. Per-

manently coupled hoses cannot be repaired.

D Handle and route hoses and tubes carefully. Keep hoses and tubes away from moving parts and

hot surfaces. Do not kink or over bend the hoses or use the hoses to pull equipment. Do not expose Graco hoses to temperatures above 180_F(82_C) or below --40_F(--40_C).

FIRE AND EXPLOSION HAZARD

Improper grounding, poor air ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury.

D Ground all equipment in the work area. See Ground the System on page 5.

D If there is any static sparking while using the equipment, stop spraying immediately. Identify

and correct the problem.

D Provide fresh air ventilation to avoid the buildup of flammable vapors from solvent or the fluid be-

ing sprayed.

D Do not smoke in the spray area.

D Extinguish all open flames or pilot lights in the spray area.

D Do not turn on or off any light switch in the spray area.

D Electrically disconnect all equipment in the spray area.

D Keep the spray area free of debris, including solvent, rags and gasoline.

D Do not operate a gasoline engine in the spray area.

D Keep a fire extinguisher in the work area.

WARNING

EQUIPMENT MISUSE HAZARD

INSTRUCTIONS

Equipment misuse can cause the equipment to rupture, malfunction or start unexpectedly and result in serious injury.

D This equipment is for professional use only.

D Read all instruction manuals, tags, and labels before operating the equipment.

D Use the equipment only for its intended purpose. If you are in doubt about this, call your Graco

distributor.

D Do not alter or modify this equipment.

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

D Do not exceed the maximum working pressure of the lowest rated system component. Refer to

the Technical Data on page 15 for the maximum working pressure of this equipment.

D Do not move or lift pressurized equipment.

D Use fluids or solvents which are compatible with equipment wetted parts. Refer to the Technical

Data section on page 15 and all equipment manuals. Read the fluid and solvent manufacturer’s warnings.

D Do not use 1,1,1--trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or

fluids containing such solvents in pressurized aluminum equipment. Such use could result in a chemical reaction, with the possibility of explosion.

D Fluid hoses must have spring guards on both ends to protect them from rupture caused by kinks

or bends at or close to the couplings.

D Comply with all applicable local, state and national fire, electrical and other safety regulations.

TOXIC FLUID HAZARD

Improper handling of hazardous fluids or inhaling toxic fumes can cause extremely serious injury, even death, due to splashing in the eyes, ingestion, or bodily contamination.

D Know the specific hazards of the fluid you are using.

D Store hazardous fluid in an approved container. Dispose hazardous fluid according to all local,

state and national guidelines.

D Wear appropriate clothing, gloves, eyewear and respirator.

RECOIL HAZARD

Due to the high pressure fluid emitted, a strong recoil action may occur when you trigger this gun. If you are unprepared, your hand could be forced back toward your body or you could lose your balance and fall, resulting in serious injury.

Installation/Operation

System Requirements

WARNING

Keep the wallet-sized warning card provided with this gun with the operator at all times. The card contains important treatment information should an injection injury occur. Additional cards are available at no charge from Graco Inc.

1. The pressure drain valve assists in relieving fluid pressure in the displacement pump, hose and gun; triggering the gun to relieve pressure may not be sufficient.

2. Strain the fluid you are spraying if it contains particles which could clog the spray tip.

Ground the System

WARNING

Pressure Relief Procedure

WARNING

To reduce the risk of serious injury, including fluid injection, splashing fluid or solvent in the eyes or on the skin, follow this procedure when you are instructed to relieve pressure, when you stop spraying, shut off the pump, check or service any system equipment, or install, clean or change spray tips.

1. Lock the gun trigger safety.

2. Shut off the power to the pump.

3. Unlock the gun trigger safety.

4. Hold a metal part of the gun firmly to a grounded metal pail. Trigger the gun to relieve pressure.

5. Lock the gun trigger safety.

6. Open the drain valve, having a container ready to catch the drainage. Observe the pressure gauge. The gauge reads 0 psi/bar when fully drained. Leave the drain valve open until you are ready to spray again.

To reduce the risk of static sparking, ground the pump and all other equipment used or located in the spray area. Check your local electrical code for detailed grounding instructions for your area and type of equipment. Also follow the grounding instructions provided in your pump or sprayer manual. The gun obtains grounding through connection to a properly grounded fluid hose and pump or sprayer. Also read FIRE OR EXPLOSION HAZ-

ARD on page 3.

How to Use the Gun Trigger Safety

1. To lock the gun trigger safety, turn the safety to a right angle with the gun body. See Fig. 1.

2. To unlock the gun trigger safety, push the safety out and turn it parallel with the gun body. See Fig. 1.

If you suspect that the spray tip or hose is completely clogged or that pressure has not been fully relieved, very slowly loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually. Clean the tip or hose obstruction.
