Stage two sprays material. 6. Cup: Holds material; includes a vented cap. -10- Model H8115/H8117 Spray Gun SECTION 4: OPERATIONS ADANGER 4 EXPLOSION HAZARD! DO NOT smoke or have any source of flame or spark near spraying. Vapors will explode if ignited. ▲WARNING RESPIRATORY HAZARD! Always use respirator rated for organic vapor and solvent use when using spray equipment. Failure to protect your lungs can lead to respiratory illness and nervous system damage. ▲WARNING TOXIC FUMES! Always use an approved spray booth or well ventilated area when spraying. NEVER spray in a confined space where toxic fumes and flammable vapors can accumulate to deadly levels. Spraying The Model H8115/H8117 is designed to spray liquids paints and lacquers that are low viscosity or have been thinned down. It is ideal for auto body touch-ups, woodworking projects, and projects with hard to reach areas. To use your spray gun: 1. Read and follow the material manufacturer's instructions for spraying, mixing, safety, disposal, and any other instruction on the label or Material Safety Data Sheet (MSDS). 2. Ensure the cup is securely tightened and all other fittings are secure to avoid air leaks or material spills. 3. To start, set the inlet air pressure (the air coming to the spray gun) to the lowest pressure recommended in Tool Data on Page 8 or to the material manufacturer's recommendations. You can adjust as necessary from there. 4. Adjust the atomizing cap to vertical or horizontal. See Atomizing Cap and Fan Adjustments on Page 13 for further explanation. 5. Fill the cup with material. 6. Trial and error are necessary to achieve the results you want along with a fair amount of practice. Test your material flow and spray pattern on a piece of cardboard or scrap material similar to your project. Model H8115/H8117 Spray Gun -11- 7. Adjust the fluid control knob to start with a low volume of material and keep the atomization as low as possible. Use a combination of fluid control, inlet air pressure, air flow control and stroke speed to achieve the results you want. Spray so the material wets out nicely without running or sagging. 8. Use the pattern control knob to adjust the spray fan to your desired pattern. 9. Keep the gun tip perpendicular and parallel to the work surface as you spray from a distance of 152-203mm (6-8") as shown in Figure ??. Keep your wrist firm while spraying; bending your wrist will cause the gun to arc across the surface and distribute the material unevenly, possibly creating sags, drips or dry spots. 10. Begin spraying 2-3 inches before the work. Continue the motion for a few inches past the work until you are ready for the return stroke. NOTICE Tipping the Model H8117 spray gun may cause material to spill out of the cup. Always hold the spray gun perpendicular to the ground to avoid potential spills and gravity feed problems. 11. Maintain an even speed when spraying. 12. Overlap each stroke by 50%. This will ensure even coverage as shown in Figure 6. Less than 50% as shown in the figure to the right may lead to missed spots or streaky results. 13. Spray stroke should be consistently even with parallel edges. If it doesn't please refer to Troubleshooting on Page 17. 14. To orient the H8115 spray gun downward or upward, loosen the nut that secures the cup to the gun, adjust the gun angle and tighten the nut. Awarning HEALTH & CONTAMINATION HAZARD! Dispose of paint waste in a responsible manner! Follow manufacturer's recommendations and local laws regarding disposal. Failure to comply will result in contamination and possibly large fines and penalties. -12- Model H8115/H8117 Spray Gun Atomizing Cap and Fan Adjustments The atomizing cap needs to be adjusted for horizontal (Figure 7 & 8) or vertical (Figure 9 & 10) spraying patterns. Spraying in the opposite direction may lead to material build up on the atomizing cap horn. Many performance problems are caused by clogged atomizing holes on the atomizing cap horns (see Cleaning on Page 15). Figure 7. Set up for horizontal stroke, Model H8115. Figure 8. Set up for horizontal stroke, Model H8117. Figure 9. Set up for vertical spray stroke, Model H8115. Figure 10. Set up for vertical spray stroke, Model H8117. Rotating the pattern adjustment control in Figure 9 or 10 will give you a range between the two patterns in Figure 11 . Figure 11. Fan adjustment, Model H8115.
