IMPORTANT SAFETY INSTRUCTIONS
1. INJECTION HAZARD! Although this paint gun is airless, it still puts out paint at a very high pressure. Through improper use, paint can be injected through a person's skin, leading to serious injury, possibly amputation. If paint is accidentally injected into someone's skin, contact a doctor immediately. Do not treat an injection injury as a simple cut. Injection can lead to amputation and requires immediate surgical treatment.
2. Do not direct spray at people or animals. Do not place your hand in front of Spray Gun's nozzle or attempt to deflect paint spray with your hand during use. Gloves and clothing don't offer adequate protection from toxic paints, sealers, or stains.
3. Do not spray flammable materials in vicinity of open flame or near ignition sources. Motors, electrical equipment, andcontrols can cause electrical arcs that will ignite a flammable gas or vapor. Do not store flammable liquids or gases in vicinity of this unit.
4. Do not come into contact with a fluid stream created by a leak in the paint hose. 5. Do not leave Paint Sprayer pressurized while unattended. 6. Do not clean Spray Gun tip while it is still connected to paint hose.
7. Keep the trigger and the electrical cord plug clean and paint-free. 8. Do not run Paint Sprayer while empty. Damage to the unit may occur. 9. Do not use Paint Sprayer to spray asbestos, metallic paints, glazes, red lead, cement, ground chalk, abrasive grainy
paints containing lime, or bleach. These will damage the spray gun and void the warranty. 10. Read all of the information concerning coating products and cleaning solvents.
Do NOT use bleach, low-flash naphthalene, acetone, alcohol or toluene when cleaning Paint Sprayer equipment. 11. Do not use bleach or halogenated hydrocarbon solvents (DCM, 1,1,1trichloroethane, methyl bromine, carbon
tetrachloride, and ethyl iodide). Long term exposure to many chlorinated hydrocarbons through inhalation can result in liver and kidney toxicity. Exposure of unprotected skin to the solvents used can cause defatting of the skin resulting in dermatitis. Methylene chloride and vinyl chloride have also been shown to be human carcinogens. Some of these solvents are flammable. Welding operations near the these materials can create phosgene, a highly toxic gas. 12. Many spray guns contain aluminum, which reacts strongly to chlorinated solvents. Contact the solvent or coating manufacturer as needed regarding potential chemical reactions.
13. Industrial applications must follow OSHA requirements.
14. Spraying hazardous materials may result in serious injury or death. Do not spray pesticide, acid, corrosive material, fertilizer, or toxic chemicals.
15. Paints and solvents may be harmful or fatal if swallowed or inhaled. Avoid prolonged skin contact with solvents or paints as they will irritate skin. After any contact, immediately wash off exposed area with hot, soapy water.
16. Keep paint hose away from sharp objects. Bursting hoses may cause injury. Examine hoses regularly and replace if damaged.
17. When flushing Paint Sprayer system, use lowest possible pressure setting. 18. All hoses and spray gun accessories used with Paint Sprayer must be pressure rated at or above 3000 PSI. 19. The Paint Sprayer must be plugged into an outlet that is grounded in accordance with all local codes and
ordinances.
20. Use caution while spraying on windy days. 21. Do not use Paint Sprayer without the Spray Gun's nozzle guard in place. 22. Paint Sprayer's housing may become hot during use.
Do not touch housing until it has completely cooled. 23. Remove Spray Tip or turn to cleaning position BEFORE cleaning or flushing Paint Sprayer system. 24. Do not use pliers to tighten or loosen high pressure connections. 25. Sparks from improper grounding can ignite fumes!
Follow all local regulations regarding the use of fluid supply containers and solvent pails used with flushing the Paint Sprayer. Use only conductive metal pails placed on a grounded (concrete) surface. Do not place pails on nonconductive surfaces (such as cardboard or paper). Ground all metal pails by clamping one end of a ground wire to the pail and the other end to a grounded structure (such as a nearby pipe). Maintain grounding, even when flushing or relieving pressure from Paint Sprayer into metal pail. The force of the spray can knock a metal pail over, so hold down the metal pail and keep the metal part of the spray gun set against the grounded metal pail when pressing the spray gun trigger. 26. People with pacemakers should consult their physician(s) before use. Electromagnetic fields in close proximity to heart pacemaker could cause pacemaker interference or pacemaker failure.

GROUNDING

TO PREVENT ELECTRIC SHOCK AND DEATH FROM INCORRECT GROUNDING WIRE CONNECTION: Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.

Grounded Tools: Tools with Three Prong Plugs

3-Prong Plug and Outlet

Electrical Power Requirements
110 - 120 Volts 60 Hertz 15 amp outlet,required. Ensure that the power supply is operating normally.

1. Sprayers marked with "Grounding Required" plug. The plug must be connected to a properly malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electric shock. (See 3-Prong Plug and Outlet.)
2. The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the sprayer. The green wire in the cord must be the only wire connected to the sprayer's grounding system and must never be attached to an electrically "live" terminal. (See 3-Prong Plug and Outlet.)
3. The sprayer must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the preceding illustration. (See 3-Prong Plug and Outlet.)

Extension Cords
1. Grounded sprayers require a three wire extension cord. Double Insulated sprayers can use either a two or three wire extension cord.
2. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible sprayer damage. (See Table A.)
3. The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a14 gauge cord can carry a higher current than a 16 gauge cord. (See Table A.)
4. When using more than one extension cord to make up the total length, make sure each cord contains at least the minimum wire size required. (See Table A.)
5. If you are using one extension cord for more than one sprayer, add the nameplate amperes and use the sum to determine the required minimum cord size. (See Table A.)
6. If you are using an extension cord outdoors, make sure it is marked with the suffix "W-A" ("W" in Canada) to indicate it is acceptable for outdoor use.
7. Make sure the extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.
8. Protect the extension cords from sharp objects, excessive heat, and damp or wet areas.
