THE HERO HVLP ADVANTAGE HERO Turbine-Powered HVLP Sprayers are powered by an electric turbine which supplies a consistent flow of high volume, low pressure air (4-6 PSI @ 95-130 CFM) to the spray gun to atomize the paint or coating (dye, lacquer, adhesive, etc.) being applied. By spraying at low pressure, the coating does not bounce back from the surface as with conventional high pressure spraying systems powered by a pump or a compressor.
GETTING STARTED 2.1 UNPACKING YOUR HERO SYSTEM Unpack your new HERO system from the box.
2.4 CONNECTING THE HOSE TO THE TURBINE With the power switch in the OFF position, uncoil the air hose and screw it hand-tight to the turbine air outlet. Although the hose is designed for industrial use, it is not crushproof. Do not stand on the hose for extended periods. For information on wire-bound crushproof hoses, please contact your local HERO distributor or HERO directly.
GENERAL OPERATING INSTRUCTIONS 3.1 OPERATING INSTRUCTIONS AND PAINTING TIPS For the specific Operating Instructions and Painting Tips of your HERO sprayer, please refer to the laminated card attached to the turbine handle of your system. If this card is missing or has been lost, please contact your local HERO distributor or HERO directly, we will be pleased to mail, fax, or e-mail you a new copy. The following general instructions are meant to be a guideline for success with your HERO sprayer.
Viscosity Chart Properties and thickness of coatings vary from one manufacturer to another. The following chart is a guideline only. Use these times as a guideline in determining the appropriate viscosity based on your spraying technique and finish standards. Some high solids coatings may exceed a reasonable viscosity and still be sprayable.
The size of the Air Cap is determined by the size of the center hole. Every Air Cap is stamped with number 1, 2, or 3 to indicate the range in size. The larger the center hole (No. 3), the greater the amount of atomizing air around the Fluid Tip. To ensure proper performance, ensure that the Air Cap hole is large enough to allow atomizing air to flow freely around the Air Cap, but not so large that it will create a distorted pattern. Trial and error is often the best way to select the appropriate Air Cap.
3.4 SURFACE PREPARATION Ensure that the surface you are spraying is clean, dry, and free from dust, oil, grease or any other contaminant. A dirty or greasy surface will affect adhesion, can spoil a finish and is very difficult to correct once sprayed. If possible, always clean the surface with a tack rag to remove any dust or lint. Do not wipe the surface with your hand – body oil may stay on the part and ruin the surface preparation. 3.
3.7 OPERATING THE SPRAY GUN Fill the cup as necessary (up to the shoulder maximum) with the properly diluted paint or coating. Do not overfill the cup as this may cause leakage or may block the air pressure holes and prevent pressurization of the cup. Spray Pattern Selection To select the desired spray pattern, rotate the Air Cap at the front of the gun.
The direction of the spraying motion should be based on the spray pattern chosen: when spraying a horizontal pattern, the direction should be up and down; when spraying a vertical pattern, the direction should be left to right or right to left; when spraying a round pattern, the direction can be either. CAUTION: Once you have filled the spray gun, it is important to keep the gun upright.
Even Drip Figure 8 Running/Dripping From Extremities 3.9 Running/Dripping From Center BASIC SPRAYING TECHNIQUES ?? For applications where thicker coats are required and finish quality is critical, consider applying two thinner coats. The reduction in paint consumption and drying time when spraying with HERO systems often justifies the additional step. ?? Hold the gun perpendicular to the surface being sprayed, maintain a consistent distance from the surface (approx.
Correct Application Technique Incorrect Application Technique Overlap strokes up to 50% to ensure proper coverage and avoid streaks: When spraying an edge or corner, split the center of the spray pattern on the corner or edge so that each side receives 50% of the spray pattern and equal amounts of paint: HERO Operator’s Manual – Page 13 of 23
CLEANING AND MAINTENANCE 4.1 BASIC CLEAN UP If you are taking a break or plan to spray the same material again within a reasonable time: 1. Turn off the turbine and disconnect the gun from the hose. 2. Turn the Material Flow Adjustment Screw at the back of the gun clockwise until it stops and clean any excess coating remaining on the Fluid Tip. This will ensure that the Needle closes the Fluid Tip air tight, allowing you, depending on the coating, to leave the material in the cup for extended periods.
4.3 COMPLETE DISASSEMBLY AND CLEANING OF SPRAY GUN Periodically, especially after spraying an adhesive, a catalyzed coating, or any other material that is known to be difficult to clean, HERO recommends that you completely disassemble your gun and clean each part individually. If necessary, contact your local HERO distributor or HERO directly for a parts breakdown of your gun, or for any help when completely disassembling and re-assembling your gun.
enlarge the holes of these critical parts and affect the performance of your system when used. When re-assembling the gun, it is recommended to apply a little white grease or petroleum jelly on all threaded and tight tolerance parts: Material Flow Adjustment Screw and Spring; Air Distributor; Sleeve Nut; tip of Needle. 4.4 CHANGING THE NEEDLE, FLUID TIP AND AIR CAP Select the Needle, Fluid Tip and Air Cap combination based on the coating being sprayed, the application speed and finish required.
The Gland Seal is located behind the Gland Nut directly in front of the gun trigger and should be replaced periodically as part of preventive maintenance. A worn Gland Seal can be the cause of leaking between the Gland Nut and the Needle directly in front of the trigger. If leaking occurs, try tightening the Gland Nut before changing the Gland Seal. To Replace The Gland Seal: 1. Remove the Material Flow Adjustment Screw, Spring and Needle from the back of the gun. 2.
TROUBLE SHOOTING 5.1 BASIC TROUBLESHOOTING CHART Problem Turbine not working at all Low Air Flow Probable Cause Solution(s) A. No power to the turbine B. Re-settable breaker has been activated A. Filters are blocked A. Check power outlet/socket B. Re-set breaker on face of turbine by pressing it once A. Clean or replace filters as necessary B. Allow air to flow freely around turbine C. Remove kink and straighten hose D. Inspect hose: repair or replace if necessary E.
5.1 BASIC TROUBLESHOOTING CHART (Continued) Problem Not Spraying At All or Inconsistent Material Flow (spitting) With A Cup Gun Probable Cause A. Air Cap too far from Fluid Tip B. Dry paint on end of Fluid Tip C. Coating is too thick: not enough pressure to pump from cup to Fluid Tip D. Foreign/unwanted particles in the coating Not Spraying At All or Inconsistent Material Flow (spitting) With A Pressure-Fed Gun E. Air Pressure Feed Tube blocked: preventing pressurization of paint cup F.
5.2 TROUBLESHOOTING FINISH PROBLEMS Problem Runs or Sags Probable Cause A. Coating has been overdiluted B. Application speed too slow C. Improper overlapping D. Needle and Fluid Tip too large E. Film thickness is too thick for one coat F. Gun too close to surface G. Insufficient atomizing air “Orange Peel”: Finish has the texture of an orange peel. A dimpled appearance, often very glossy. A. Insufficient dilution B. Incorrect thinning solvent: solvent is evaporating too fast C.
