Sprayer Controls:
To adjust the spray pattern, loosen the Nozzle Retainer (2) by turning it counter-
clockwise, then rotate the Air Nozzle (1), then retighten the Nozzle Retainer (2). For
a vertical spray pattern, the “ears” of the Air Nozzle (1) should be horizontal. For a
horizontal pattern, the “ears” should be vertical. In other words, the position of the
Air Nozzle and the spray pattern are opposite.
To control the amount of paint mixture being sprayed, adjust the Fluid Valve
Control Knob (33). Turning the Knob clockwise will reduce the amount of paint,
turning it counterclockwise will increase the amount of paint available. CAUTION:
Do not overtighten the Knob, as this will cut off the paint supply, and may damage
the Fluid Needle Seats (30). Do not remove the Fluid Adjusting Valve Assembly
(28).
To control the amount of air pressure passing through the Sprayer, adjust the
Air Valve Control Knob (40). Turning the Knob clockwise will reduce the air pres-
sure, and turning it counterclockwise will increase the air pressure. CAUTION: Do
not overtighten the Knob, as this will cut off the air supply, and may damage the Air
Ball Valve (36). Do not remove the Air Adjusting Valve Assembly (34).
To adjust the Trigger Valve Assembly (22), turn the Trigger Valve Adjust Knob
clockwise to reduce the pressure required on the Trigger (8) to operate. Turn the
Trigger Valve Adjust Knob counterclockwise to increase the pressure required on
the Trigger (8) to operate.
The solvent is also used as a clean up medium. Paint mixtures which are to be
sprayed are generally less viscous (thinner) than mixtures which are to be applied
with a brush. Thus you will most often have to add extra solvent to a paint which is
to be sprayed.
When paint is sprayed, it is broken into tiny droplets, then blown by high-
pressure air onto the surface. During this spraying process, the surface of each
paint droplet will begin to dry. When it hits the work material, the droplet must liquefy
again, and mix with the droplets hitting alongside it. Ideally, these droplets will mix
evenly forming a smooth surface.
If the paint mixture is too thick, the droplets will not form a smooth layer, and
the resulting surface can be described as “pebbly” or “orange peel”. If the paint
mixture is too thin, the paint will run, forming long drips before they are thick enough
to form a satisfactory coat. Vertical surfaces are more prone to “run” than horizontal
surfaces due to the effect of gravity.
