MOVING PARTS HAZARD 
Moving parts can pinch or amputate your fingers or other body parts. KEEP CLEAR of moving parts when starting or operating the sprayer. Follow the Pressure Relief Procedure on page 2 before checking or servicing any part of the sprayer, to prevent it from starting accidentally.
EQUIPMENT MISUSE HAZARD
General Safety
Any misuse of the spray equipment or accessories, such as overpressurizing, modifying parts, using incompatible chemi- cals and fluids, or using worn or damaged parts, can cause them to rupture and result in fluid injection, splashing in the eyes or on the skin, or other serious bodily injury, or fire, explosion or prop- erty damage.
NEVER alter or modify any part of this equipment; doing so could cause it to malfunction.
CHECK all spray equipment regularly and repair or replace worn or damaged parts immediately.
Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and solvent manufacturer.
System Pressure
This sprayer can develop 2500 psi (172 bar) MAXIMUM WORK- ING PRESSURE. Be sure all spray equipment and accessories used are rated to withstand the this pressure. DO NOT exceed the maximum working pressure of any component or accessory used in the system.
Fluid and Solvent Compatibility
All chemicals used in the sprayer must be chemically compatible with the wetted parts shown in the TECHNICAL DATA on page 34. Consult your chemical supplier to ensure compatibility.
Do not use
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If the hose develops a leak, split or rupture due to any kind of wear, damage or misuse, the high pressure spray emitted from it can cause a fluid injection injury or other serious bodily injury or prop- erty damage.
ALL FLUID HOSES MUST HAVE STRAIN RELIEFS ON BOTH ENDS! The strain reliefs help protect the hose from kinks or bends at or close to the coupling which can result in hose rupture.
TIGHTEN all fluid connections securely before each use. High pressure fluid can dislodge a loose coupling or allow high pres- sure spray to be emitted from the coupling.
NEVER use a damaged hose. Before each use, check the entire hose for cuts, leaks, abrasion, bulging cover, or damage or movement of the hose couplings. If any of these conditions exist, replace the hose immediately. DO NOT try to recouple high pres- sure hose or mend it with tape or any other device. A repaired hose cannot contain the high pressure fluid.
HANDLE AND ROUTE HOSES CAREFULLY. Do not pull on hoses to move equipment. Keep hoses clear of moving parts and hot surfaces of the pump. Do not use fluids or solvents which are not compatible with the inner tube and cover of the hose. DO NOT expose Graco hoses to temperatures above 180_ F (82_ C) or below ±40_ F (±40_ C).
Hose Grounding Continuity
Proper hose grounding continuity is essential to maintaining a grounded spray system. Check the electrical resistance of your fluid hoses at least once a week. If your hose does not have a tag on it which specifies the maximum electrical resistance, con- tact the hose supplier or manufacturer for the maximum resis- tance limits. Use a resistance meter in the appropriate range for your hose to check the resistance. If the resistance exceeds the recommended limits, replace it immediately. An ungrounded or poorly grounded hose can make your system hazardous. Also read FIRE OR EXPLOSION HAZARD, below.
FIRE OR EXPLOSION HAZARD
Static electricity is created by the flow of fluid through the pump and hose. If every part of the spray equipment is not properly grounded, sparking may occur, and the system may become haz- ardous. Sparking may also occur when plugging in or unplugging a power supply cord or using a gasoline engine. Sparks can ignite fumes from solvents and the fluid being sprayed, dust particles and other flammable substances, whether you are spraying in- doors or outdoors, and can cause a fire or explosion and serious bodily injury and property damage. Always plug the sprayer into an outlet at least 20 feet (6 m) away from the sprayer and the spray area. Do not plug in or unplug any power supply cords in the spray area when there is any chance of igniting fumes still in the air.
If you experience any static sparking or even a slight shock while using this equipment, STOP SPRAYING IMMEDIATELY. Check the entire system for proper grounding. Do not use the system again until the problem has been identified and corrected.
Grounding
To reduce the risk of static sparking, ground the sprayer and all other spray equipment used or located in the spray area. CHECK your local electrical code for detailed grounding instruc- tions for your area and type of equipment. BE SURE to ground all of this spray equipment:
1.Sprayer: plug the power supply cord, or extension cord ± each equipped with an undamaged, three±prong plug, into a properly grounded outlet. Do not use an adapter. All exten- sion cords must have three wires and be rated for 15 Amps.
2. Fluid hoses: use only grounded hoses with a maximum f 500 ft. (150 m) combined hose length to ensure grounding continuity. See Hose Grounding Continuity on page 3.
3.Spray gun: obtain grounding through connection to a prop- erly grounded fluid hose and sprayer.
4.Object being sprayed: according to local code.
5.Fluid supply container: according to local code.
6.All solvent pails used when flushing, according to local code. Use only metal pails, which are conductive. Do not place the pail on a non±conductive surface, such as paper or card- board, which interrupts the grounding continuity.
7.To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the gun firmly to the side of a grounded metal pail, then trigger the gun.
Flushing Safety
Reduce the risk of fluid injection injury, static sparking, or splash- ing by following the flushing procedure given on page 13 of this manual. Follow the PRESSURE RELIEF PROCEDURE on page 2, and remove the spray tip before flushing. Hold a metal part of the gun firmly to the side of a grounded metal pail and use the lowest possible fluid pressure during flushing.
