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.
ALWAYS þ þ þ þ þ þ þ þ þ þ þ þ þ þ 1. 2. 3. 4. þ þ þ þ ALWAYS follow H.E.R.O. recommendations for operation and safety completely. ALWAYS ensure that switch is in off position before plugging in the electric motor. ALWAYS set trigger lock on gun in "LOCKED" position when not in use, with gun locked close. ALWAYS check connections and fittings for tightness before operating the unit. ALWAYS locate the unit in a well ventilated area a minimum of 25 feet from the spray area.
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 300S or 300SL. 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.
SETTING UP TO SPRAY 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Remove unit from shipping carton. Inspect exterior of unit for any signs of freight damage. If any parts are found to be broken or damaged, immediately contact the carrier and arrange for an inspection of the concealed damage. Claims for freight damage must be made by the CONSIGNEE and not by the shipper. The carrier accepts full responsibility for the safe delivery of merchandise upon pick- up from the shipper.
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 sprayer.
SPECIAL NOTES AND INSTRUCTIONS NEVER LEAVE THE UNIT UNDER PRESSURE WHEN NOT SPRAYING (MOTOR TURNED OFF). RELIEVE PRESSURE BY TRIGGERING GUN. NEVER STORE THE UNIT WITH PAINT OR WATER IN THE PUMP SYSTEM, EVEN OVERNIGHT. ý NEVER attempt to start the motor when the unit is under pressure. Relieve pressure and follow instructions in "Setting up to spray" ý NEVER attempt to run the motor on longer or lighter extension cord than specified. ý Avoid operating the unit while tilted.
AIRLESS SPRAY PAINTING SUGGESTIONS AND TECHNIQUE A good airless spray application is the result of many factors. Surface preparation, which includes cleaning and degreasing, priming, material compatibility, quality finish product and correct application technique, are all important to the finished results. The key to all good applications is a good spray gun technique. The finished results are what the client will look at and base his opinion on.

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 better able to diagnose and make repairs. All H.E.R.O.
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.
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.
TROUBLESHOOTING SITUATION POSSIBLE CAUSE (REMEDY) ELECTRIC MOTOR WON'T START/RUN 1. Unit unplugged or building circuit fuse is blown. (check, replace or reset fuse) 2. Pump under pressure. (reduce pressure setting by turning pressure control knob counter-clockwise, trigger gun to relieve pressure). 3. Too light or too long of extension cord. (replace with correct cord. If distance greater than 100 feet, obtain and install extra length of H.E.R.O. airless spray hose). 4.
TROUBLESHOOTING SITUATION POSSIBLE CAUSE (REMEDY) TOTAL LOSS OF PRESSURE, DIAPHRAGM HAS NO MOVEMENT OR MOVEMENT CAN BE STOPPED...CONTINUED. 2. Air lock created on hydraulic side of pump. (air entering hydraulic side due to loose hydraulic feed line fittings, (ref# 63), punctured hydraulic feed line, poor seal at hydraulic intake valve, (ref# 62), or elbow, (ref# 61). Tighten hydraulic feed line, test for leaks, or apply Teflon tape or pipe sealant on fittings. Purge air as per detailed instructions below).
TROUBLESHOOTING SITUATION POSSIBLE CAUSE (REMEDY) PUDDLE OF OIL APPEARING UNDER SPRAYER DURING OPERATION 1. Hydraulic fitting loose/cracked or hydraulic lines are punctured. (examine all hydraulic lines and fittings for cracks, breaks or looseness. Replace or tighten as required). 2. Piston seals (ref# 90) worn. (remove and replace piston seals, following closely the detailed instructions on page 28-29).
TROUBLESHOOTING SITUATION POSSIBLE CAUSE (REMEDY) FLUID BEING SPRAYED OUT OF TIP PULSATES, SPRAY HOSE LIES QUIET WHEN GUN TRIGGER CLOSED 1. Spray tip worn out or too large. (replace with new tip of correct size. Tip must not exceed a good condition .021 tip ). 2. Paint hose incorrect type. (replace with genuine top quality H.E.R.O. airless spray hose. Steel braided hose is not recommended ). 3. Too short a length of hose. (minimum 50' of airless spray hose is required.
TROUBLESHOOTING SITUATION POSSIBLE CAUSE (REMEDY) SPRAY MATERIAL LEAKS AT PRIME VALVE STEM 1. Prime valve stem packings (ref# 38 or 39) defective. (replace damaged packings following detailed instructions on page 25. SPRAY MATERIAL LEAKS OUT PRIME VALVE HOSE WITH VALVE CLOSED 1. Prime not closed tightly. (tighten valve handle (ref# 43) further) 2. Prime valve worn. ( install prime valve repair kit, (ref# 47). See page 25 for detailed instructions.) SPRAY PATTERN IS SPOTTY OR UNEVEN 1. Pressure is too low.
