INTRODUCTION & UNPACKING Congratulations on your purchase of a new H.E.R.O. H2K airless paint sprayer. We are sure you will enjoy owning and operating your new sprayer. With H.E.R.O. airless spray equipment you will enjoy the features and benefits of this airless. 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, FLUSHING, PRIMING, SPRAYING, SHUT DOWN Flushing: 1. Have two pails ready; one for flushing fluid and one for waste. 2. If you are using latex paint, fill the flushing pail with approximately 1 gallon of warm soapy water. For oil based paints, use approximately 1 gallon of mineral spirits. 3. Place the siphon hose in the “flushing” pail and the bleed tube in the “waste” pail. 4.
SPRAYING & SHUT DOWN Spraying: 1. Turn unit on. 2. Trigger gun, and increase pressure slowly. Continue to increase the pressure until the spray pattern is uniformed from top to bottom, with no heavy areas. If heavy areas are still visible at maximum pressure settings, thin paint with the correct thinner, according to the paint manufacturer’s instructions. Spray test patterns onto old newspaper or other scrap material. Always use the lowest possible pressure setting to atomize paint fully.
AIRLESS SPRAY PAINTING SUGGESTIONS 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. All are all important to the finished results. The key to all good applications is a good spray gun technique. Proper application techniques can easily be learned by using the following simple guidelines.
AIRLESS SPRAY PAINTING SUGGESTIONS FIG. 4 FIG. 3 FIG. 5 SPRAY TIP SELECTION It is advisable to obtain a spray tip recommendation from the supplier of the material to be sprayed. The following table is a general guide and will assist in selecting the optimum tip to use. TIP SIZE USED TYPICALLY FOR SPRAYING THESE MATERIALS APPROX. GPM Suggested filter (color) white .019 Exterior Latex on large unobstructed areas. .47 .017 Interior Latex, Exterior Latex, Shake Paint, Exterior Flat Paints. .31 .
SPRAY TIP SELECTION ORIFICE SIZE All tips are rated by the size of the orifice or bore size. The bore size is measured in thousandths of an inch ( .017 = 17 thousandths of an inch ). The size of tip required is based on the consistency of the material to be sprayed. The thicker the paint, the larger the tip size required. Always consult the product label or ask the paint retailer for the manufacturer's recommendations with regard to proper tip sizes.
REPAIR PROCEDURES The H.E.R.O. H2K units were specifically designed to assist the operator in dealing with the inconvenient, time consuming, and some times technically challenging concept of equipment service and repair. The H2K models offer simple, quick, easy to perform procedures for any and all the fluid section repair procedures. Servicing and the repair of the fluid section can be performed with one simple tool, the H.E.R.O. “UNI-TOOL™” , (Part # HK1000).
REPAIR PROCEDURES 6. Using the 5/8” socket end of the Uni-Tool, remove the entire fluid section assembly as shown in Fig # 4 and # 5 by turning it counter clockwise until it is fully removed from connecting rod and manifold. Fig # 6 Fig # 4 Fig # 5 The entire fluid section is now removed, awaiting further repairs or service. Refer to the various service repairs on the pages to follow.
REPAIR PROCEDURES PISTON CARTRIDGE ASSEMBLY REPAIRS – DISMANTLING The piston cartridge assembly is available as a complete, pre-assembled cartridge for quick, on site, unit repairs. Items are also available individually for more economical repairs when time is not of the essence. We recommend keeping a new or previously re-build piston cartridge assembly in your tool box at all times, for those urgent on the job replacements.
REPAIR PROCEDURES PISTON CARTRIDGE ASSEMBLY REPAIRS – ASSEMBLY 1. Slide o-rings (Ref # 14 & 15) onto the piston valve body (Ref # 13).
