Caution Symbol CAUTION This symbol alerts you to the possibility of damage to or destruction of equipment if you do not follow the corresponding instructions. INSTRUCTIONS EQUIPMENT MISUSE HAZARD Equipment misuse can cause the equipment to rupture, malfunction, or start unexpectedly and result in serious injury. This equipment is for professional use only. Read all instruction manuals, warnings, tags, and labels before operating the equipment. Use the equipment only for its intended purpose. If you are uncertain about usage, call your Graco distributor. Do not alter or modify this equipment. Use only genuine Graco parts and accessories. Check the equipment daily. Repair or replace worn or damaged parts immediately. Do not exceed 125 (0.9 MPa, 9 bar) maximum inbound air pressure to the ram. Never exceed the recommended working pressure or the maximum air inlet pressure stated on your pump or in the Technical Data on page 21. Be sure that all spray/dispensing equipment and accessories are rated to withstand the maximum working pressure of the pump. Do not exceed the maximum working pressure of any component or accessory used in the system. Route the hoses away from the traffic areas, sharp edges, moving parts, and hot surfaces. Do not expose Graco hoses to temperatures above 82 C (180 F) or below -40 C (-40 F). Do not use the hoses to pull the equipment. Use fluids and solvents that are chemically compatible with the equipment wetted parts. See the Technical Data sections of all the equipment manuals. Always read the material manufacturer s literature before using fluid or solvent in this pump. Always wear protective eyewear, gloves, clothing, and respirator as recommended by the fluid and solvent manufacturers. Wear hearing protection when operating this equipment. Comply with all applicable local, state and national fire, electrical and other safety regulations

4 HOT SURFACE AND FLUID HAZARD Heated fluid can cause severe burns and can cause equipment surfaces to become very hot. Wear protective gloves and clothing when operating this equipment in a heated system. Do not touch the metal heat sink when the surface is hot. Allow the equipment to cool thoroughly before servicing. Some heated systems are designed to dispense Polyurethane (PUR) heated materials. PUR systems are supplied with ventilation hoods, and require proper ventilation and specially designed system components. SKIN INJECTION HAZARD Spray from the spray gun, hose leaks, or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Splashing fluid in the eyes or on the skin can also cause serious injury. Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate surgical treatment. Do not point the gun/valve at anyone or at any part of the body. Do not put your hand or fingers over the spray tip/nozzle. Do not stop or deflect fluid leaks with your hand, body, glove, or rag. Always have the trigger guard on the gun when dispensing. Check the gun diffuser operation weekly. Refer to the gun manual. Be sure the gun/valve trigger safety operates before dispensing. Lock the gun/valve trigger safety when you stop dispensing. Follow the Pressure Relief Procedure in manual if the nozzle clogs, and before cleaning, checking or servicing the equipment. Tighten all fluid connections before operating the equipment. Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately. Do not repair high pressure couplings; you must replace the entire hose. Fluid hoses must have spring guards on both ends, to help protect them from rupture caused by kinks or bends near the couplings

5 FIRE, EXPLOSION AND ELECTRIC SHOCK HAZARD Improper grounding, poor air ventilation, open flames, or sparks can cause a hazardous condition and result in fire, explosion, or electrostatic shock and other serious injury. Ground the equipment, the object being dispensed, and all other electrically conductive objects in the dispense area. Proper grounding dissipates static electricity generated in the equipment. Do not use this equipment with flammable liquids. Do not stop or deflect fluid leaks with your hand, body, glove, or rag. Keep the dispense area free of debris, including solvent, rags, and gasoline. If there is any static sparking or you feel an electric shock while using the equipment, stop dispensing immediately. Do not use the equipment until you have identified and corrected the problem. Make sure all electrical work is performed by a qualified electrician only. Make sure all electrical equipment is installed and operated in compliance with applicable codes. Make sure power is disconnected when servicing and repairing equipment. Have any checks, installation, or service to electrical equipment performed by a qualified electrician only. Never exceed the maximum wattage of the supply unit. See the wiring diagrams in this manual for more information. Only use hoses that have a maximum wattage less than an equal to 1250 watts. Using hoses with higher maximum wattage could create a runaway temperature condition

6 MOVING PARTS HAZARD Moving parts, such as the ram follower plate/pump inlet can pinch fingers. Do not operate the equipment with the guard removed. Keep clear of all moving parts when starting or operating the equipment. Keep hands and fingers away from the priming piston during operation and whenever the pump is charged with air. Keep clear of the follower plate, pump fluid inlet, and lip of the fluid container when raising or lowering the ram. Before checking or servicing the ram or pump, perform the Pressure Relief Procedure in the equipment instruction manual. TOXIC FLUID HAZARD Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or swallowed. Know the specific hazards of the fluid you are using. Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local, state and national guidelines. Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and solvent manufacturer. Avoid exposure to heated material fumes. Provide adequate ventilation
