SPRAYING

PRACTICE FIRST

1.Be sure paint hose is free of kinks and clear of traffic or objects with sharp cutting edges.

2.Return PRESSURE CONTROL KNOB to its lowest setting (counterclockwise). Figure 21.

4.Turn PRESSURE CONTROL KNOB completely clockwise to maximum pressure, Figure 21. Paint should then begin to flow into the paint hose, causing it to stiffen.

Figure 23 - Practice on scrap material.

5.Unlock SPRAY GUN TRIGGER LOCK by turning lock down toward the bottom of the handle. Figure 4

6.Trigger spray gun to bleed air out of hose.

7.When paint reaches spray tip, spray a test area to check spray pattern. See Figure 23.

8.Use the lowest pressure setting necessary to get a good spray pattern. If pressure is too high, material is over-atomized. If pressure is too low, tailing will appear or paint will spatter out in gobs rather than in a fine spray. See Figure 24. Most latex paints and stains will require very high pressure, which is why the sprayer is built to deliver up to 2,500 psi when needed.
