IMPORTANT SAFETY PRECAUTIONS WARNING Material issuing from the spray tip is at high pressure. If fingers, or any part of the body are placed near the tip of the spray gun, it is possible that the spray could break the skin and inject some of the spray material. If injury does occur, seek immediate attention of a medical doctor. Be prepared to inform the doctor what fluid was injected, if the injury is of an injection nature. Equipment and chemicals when used improperly can be dangerous!

H.E.R.O. AIRLESS SPRAY PAINTING Welcome to the world of H.E.R.O. airless paint spraying. We are sure you will enjoy owning and operating your new H.E.R.O. model 3000. With H.E.R.O. airless spray equipment you will avoid the inconvenience and mess of over spray. You are spraying paint, not air, and the paint is driven to the painting surface in a clean, fan shaped spray which penetrates all cracks and corners. To attain these results, you must adjust the pressure as low as possible. We rec

FLUSHING THE UNIT AT SHUTDOWN OR COLOR CHANGE If shutting down for a short period of time, it is sufficient to trigger the gun to relieve pressure. Then set the safety lock on gun to "locked" position with the gun locked closed and immerse the gun in a container of the correct thinner for the paint you are spraying. 1. Remove spray tip from gun. 2. Turn pressure control knob counter clockwise to low pressure setting. Only use sufficient pressure to allow material to move through the

TROUBLESHOOTING Hydraulic Energy Regulated Output (H.E.R.O.) is more than just our name, it is the bases for the operation of the pump. It is the regulation or control, of hydraulic energy, which allows the equipment to build and then deliver or have an output of pressure. Once you have a basic understanding of the operation of the equipment and the effect created in one area and how it will effect operation in another area, you will be

TROUBLESHOOTING The backward movement of the piston, creates a vacuum in the hydraulic system. This causes the hydraulic outgo valve to close and the hydraulic intake valve to open (fig# 1). Opening of the hydraulic intake valve allows a new supply of hydraulic oil to enter the system, replacing the oil which was used on the forward stroke. Once again a corresponding re-action is taking place in the paint pump. The diaphragm is pushed backward by the paint intake spring, (ref# 15)

TROUBLESHOOTING PAINT OUTGO VALVE (REF# 22, PART # 4-11A) The paint outgo valve monitors and controls the flow of spray materials as it leaves the sprayer. It also works together with the paint intake valve, to build paint pressure as specified by the setting made by the hydraulic outgo valve (pressure control valve). A worn outgo valve will result in pulsation in the spray material and cause the paint hose to jump and vibrate vigorously. PRIME VALVE (REF# 34, PART # 4-606 –

TROUBLESHOOTING PRESSURE TEST To verify the performance of an airless sprayer, use of pressure gauge is required. A pressure gauge (min. 3000 psi) installed at the gun, using a new .021 tip, and not less than 50 feet of H.E.R.O. airless spray hose is needed. If you do not have access to these items, your local H.E.R.O. authorized service center will be able to perform this test. Your model 3000 is manufactured to perform at; 2650 psi -- Static pressure, with lock ring (ref# 76) on p
