When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols a

5、nd warnings not covered in this section may appear throughout the body of this manual where applicable.3A3257A3FIRE AND EXPLOSION HAZARDFlammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion: Do not spray flammable or combustible mate

6、rials near an open flame or sources of ignition such as cigarettes, motors, and electrical equipment. Paint or solvent flowing through the equipment is able to result in static electricity. Static electricity creates a risk of fire or explosion in the presence of paint or solvent fumes. All parts of

7、 the spray system, including the pump, hose assembly, spray gun, and objects in and around the spray area shall be properly grounded to protectstatic discharge and sparks. Use Graco conductive or grounded high-pressure airless paint sprayer hoses. Verify that all containers and collection systems ar

8、e grounded to prevent static discharge. Do not use pail liners unless they are static or conductive. Connect to a grounded outlet and use grounded extensions cords. Do not use a 3-to-2 adapter. Do not use a paint or a solvent containing halogenated hydrocarbons. Do not spray flammable or combustible

9、 liquids in a confined area. Keep spray area well-ventilated. Keep a good supply of fresh air moving through the area. Sprayer generates sparks. Keep pump assembly in a well ventilated area at least 20 feet (6.1 m) from the spray area when spraying, flushing, cleaning, or servicing. Do not spray pum

10、p assembly. Do not smoke in the spray area or spray where sparks or flame is present. Do not operate light switches, engines, or similar spark producing products in the spray area. Keep area clean andof paint or solvent containers, rags, and other flammable materials. Know the contents of the paints

11、 and solvents being sprayed.all Safety Data Sheets (SDS) and container labels provided with the paints and solvents. Follow the paint and solvents manufacturers safety instructions. Fire extinguisher equipment shall be present and working.MOVING PARTS HAZARDMoving parts can pinch, cut or amputate fi

12、ngers and other body parts. Keep clear of moving parts. Do not operate equipment with protective guards or covers removed. Pressurized equipment can start without warning. Before checking, mov- ing, or servicing equipment, follow the Pressure Relief Procedure and disconnect all power sources.Warning

13、sWarnings43A3257ASKIN INJECTION HAZARDHigh-pressure spray is able to inject toxins into the body and cause serious bodily injury. In the event that injection occurs, get immediate surgical treatment. Do not aim the gun at, or spray anyor animal. Keep hands and other body parts away from the discharg

14、e. For example, do not try to stop leaks with any part of the body. Always use the nozzle tip guard. Do not spray without nozzle tip guard in place. Use Graco nozzle tips. Use caution when cleaning and changing nozzle tips. In the case where the nozzle tip clogs while spraying, follow the Pressure R

15、elief Procedure for turning off the unit and relieving the pressure before removing the nozzle tip to clean. Equipment maintains pressure after power is shut off. Do not leave the equipment energized or under pressure while unattended. Follow the Pressure Relief Procedure when the equipment is unatt

16、ended or not in use, and before servicing, cleaning, or removing parts. Check hoses and parts for signs of damage. Replace any damaged hoses or parts. This system is capable of producing 3300 psi. Use Graco replacement parts or accessories that are rated a minimum of 3300 psi. Always engage the trig

17、ger lock when not spraying. Verify the trigger lock is functioning properly. Verify that all connections are secure before operating the unit. Know how to stop the unit and bleed pressure quickly. Be thoroughly familiar with the controls.PRESSURIZED ALUMINUM PARTS HAZARDUse of fluids that are incomp

18、atible 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 cont

19、aining such solvents. Do not use chlorine bleach. Many other fluids may contain chemicals that can react with aluminum. Contact your materialr for compatibility.TOXIC FLUID OR FUMES HAZARDToxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowe
