Grizzly H7670 instruction manual Spray technique

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 sag- ging.

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 at all times when spraying as shown in Figure 4. Do not allow your wrist to bend. This will cause the gun to arc across the surface and distribute the material unevenly, pos- sibly creating sags and dry spots.

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

11.Maintain an even speed when spray- ing.

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