Warning
WARNING Fire, Explosion and Electrocution Hazard Improper grounding, poor air ventilation, open flames, or sparks can cause a hazardous condition and result in fire, explosion, or electric shock. • To help prevent these hazards: • Sprayer should be grounded through an electrical outlet as follows: - Only use grounded electrical outlets. - Only use 3-wire extension cords. - Grounded prongs must be intact on sprayer and extension cords. • Keep electrical connections and inside of shroud dry. • Avoid contact with power lines. • Use outdoors or in well-ventilated area. • Sprayer should be at least 6m (20 ft) from gun when spraying or flushing. • If there is any static sparking while using equipment, stop spraying immediately. Identify and correct the problem. • Avoid all ignition sources such as pilot lights, cigarettes and plastic drop cloths (static arc hazard). • Do not plug in or unplug power cords or turn lights on or off in spray area. • Only use Graco airless paint hoses.

WARNING Pressurized Equipment Hazard To avoid component rupture and injury, do not operate sprayer with components rated less than pressure of sprayer. Sprayer is equipped with a pressure drain that automatically relieves overpressure in the event of a fault condition. This automatic pressure relief may cause splashing fluid. Correct fault before you resume spraying. Inadequate flushing and/or dried paint in drain system may prevent proper overpressure relief.
Toxic Fluid Hazard Hazardous fluids or toxic fumes can cause serious injury or death if splashed in eyes or on skin, swallowed, or inhaled. • Know specific hazards of fluid being used. Read fluid manufacturer’s warnings. • Wear appropriate protective clothing, gloves, eyewear, and respirator.
• •
Fluid Injection Hazard If high-pressure fluid pierces skin, the injury might look like “just a cut” but it is a serious wound. Get immediate medical attention. To help prevent injection: • Always engage trigger safety when not spraying. • Always shut off power and relieve pressure when you stop spraying, before you service or clean sprayer, remove parts or repair leaks. See Pressure Relief Procedure, page 9. • Do not allow children to use this equipment. • Keep clear of tip. Never point at yourself or anyone else.
• • !:! • •
Fluid Splashback Hazard To avoid splashing fluid when spraying into pail, always aim at inside wall of pail. Make sure gun is assembled with correct gasket for fluid being sprayed.

WARNING Recoil Hazard Due to the high pressure fluid emitted, a strong recoil action may occur when you trigger the 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.
Equipment Misuse Hazard Equipment misuse can cause equipment to rupture, malfunction, or start unexpectedly and cause serious injury. • Read all manuals, tags, and labels before operating equipment. • Only use equipment for its intended purpose. • Do not alter or modify equipment. • Do not exceed maximum working pressure of lowest rated system component. • Do not modify extension tube or roller frame or use parts not designed for this equipment • Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in this or any other pressurized aluminum equipment. Such use could result in a chemical reaction, with the possibility of explosion.
• ! !
• • • • • 2-2-2.
Startup Hazard After Thermal Overload Motor has thermal overload switch to shut itself down if overheated. To reduce risk of injury from motor restarting unexpectedly when it cools, always turn power switch OFF if motor shuts down.
