WATER/OIL IN COMPRESSED AIR
All compressor pumps discharge some condensed water, oil or contaminates with the compressed air.
IMPORTANT: This condensation will cause “fish eyes” to appear in the paint job. Install appropriate water/oil removal equipment and controls as necessary for the intended application. Locate filter as close to spray gun as possible.

5. Test the consistency of the material |
by making a few strokes on a card- |

(See Figure 6).
3.Turn fluid control knob fully clock- wise until closed (See Figure 6).
4.Trigger a short burst while turning fluid control knob counterclock- wise. Observe the spray pattern on the target and adjust the fluid con- trol knob until the desired pattern (atomization) is obtained (See Figure 7).

PATTERN ADJUSTMENT
1.Adjust air pressure to the spray gun according to the recommendations supplied with the spray material.
This air pressure usually falls between 40 - 60 psi.
Do not exceed
! WARNING spray gun maxi-
mum pressure.
Adjust air pressure with the trigger pulled and air control knob (if applicable) fully open. If reduced air pressure is desired for some areas of the spray job, use the air com- pressor regulator or air control knob to reduce pressure as neces- sary (See Figure 4).
