WARNING INJECTION HAZARD Spray from the 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 can also cause serious injury. D Fluid injected into the skin is a serious injury. The injury might look like just a cut, but it is a serious injury. Get immediate medical attention. D Do not point the spray gun at anyone or any part of the body.
WARNING FIRE AND EXPLOSION HAZARD Improper grounding, poor air ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury. D Ground the equipment and the object being sprayed. See Ground the system on 6. D If there is any static sparking while using the equipment, stop spraying immediately. Identify and correct the problem. D Provide fresh air ventilation to avoid the buildup of flammable vapors from solvent or the fluid being sprayed.
Setup I. Prepare the operator. All persons who operate the system should be trained in the safe, efficient operation of all system components as well as the proper handling of the chemical coating. At a minimum, all operators should thoroughly read the safety, installation and operation sections of this manual and the component manuals. II. Prepare the site. 1. Use a minimum recommended 5 HP (3.7 kW) air compressor for efficient operation. 2.
Setup III. Unpack the system. 1. In addition to the assembled components, the air and fluid hoses, gun and instruction manuals are packaged separately in the main shipping container. These are the manuals you should receive: 307–619 308–176 307–273 308–167 308–861 IV. 23:1 ratio Monark pump Air-assisted airless spray gun Fluid filter Air regulator Ball valve Connect the hoses and gun to the system. See Fig. 1. 1.
System Component Information I. How to use the air–assisted airless spray gun. With an air-assisted airless spray gun, the spray tip shapes the fluid into a fan pattern. Air from the air cap further atomizes the fluid and completes the atomization of the paint tails into the pattern to produce a more uniform pattern. II. How to change the spray pattern direction. 1. Relieve the air and fluid pressure. 2. Install a spray tip in the gun.
Operation I. Pressure relief procedure II. WARNING The system remains pressurized until pressure is manually relieved. To reduce the risk of serious injury, including skin injection from pressurized fluid or accidental spray from the gun, or injury due to splashing fluid in the eyes or on the skin, follow this procedure whenever you: D D D D are told to relieve pressure; stop spraying; check or service any system equipment; install, clean or change spray tips. Flush the pump before the first use.
Operation IV. Set the fluid and air pressure. V. 1. Install the spray tip and air cap on the gun. 2. Adjust the pump air pressure regulator until the pressure shown on the fluid filter gauge is about 800 psi (56 bar). This should require approximately 35 psi (2.4 bar) air pressure to the pump. 3. Test spray a pass or stationary horizontal pattern. Hold the gun 10 to 12 in. (250 to 300 mm) from the paper.
Flushing I. 7. Slowly turn on the pump air regulator (8a) until the pump cycles slowly. When to flush. D Before the first time use D When changing colors D Before fluid can dry or settle out in a dormant system (observe the recommended fluid pot life on catalyzed fluids) D Before storing the system II. 8. Hold a metal part of the gun firmly against the grounded metal waste pail. Trigger the gun. Slowly increase the pump air regulator setting until the fluid flows freely.
