Woodstock W1798 owner manual Overlap technique

Model W1798 Professional Spray Gun

7.Adjust the fluid control knob to start with a low volume of material and keep the atomization as low as possible. You will need to 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, parallel, and 6-8" from the work (as shown in Figure 4) when spraying. Do not allow your wrist to bend. This will cause the gun to arc across the surface and distribute the material unevenly, possibly creating sags and dry spots.

10.Begin spraying 2-3 inches before the workpiece and continue to the end of the workpiece. Continue the motion for a few inches past the work until you are ready for the return stroke.

11.Maintain an even speed when spraying.

12.Overlap each stroke by 50%. This will ensure even coverage, as shown in Figure 5. Overlapping less than 50%, as shown in the figure to the right, may lead to missed spots or streaky results.
