Operation
WARNING
To reduce the risk of over-pressurizing the equip-
ment, which could cause serious bodily injury, in-
cluding splashing in the eyes or on the skin,
never exceed 50 psi (3.5 bar) air pressure to the
cup. The relief valve is preset to relieve pressure at
50 psi (3.5 bar).
Do not alter settings on the relief
valve.
1. Turn on the air supply.
2. Turn the cup air control valve (20) clockwise, all
the way in.
3. Turn the air regulator (5) knob in until the gauge
reads 10 psi (0.7 bar). Turn the air regulator’s lock-
ing screw (E)
clockwise to lock it and counterclock-
wise to unlock it.
4. Spray a test panel. If the paint is not fully atom-
ized, either decrease the cup fluid pressure with
the air regulator (5), or increase the atomizing air
pressure with the air adjusting valve (G). Always
use the lowest possible pressure needed to
achieve the desired results.
5. To decrease the cup fluid pressure, turn the air
regulator (5) knob out (counterclockwise). Turn the
cup air control valve (20) counterclockwise mo-
mentarily to bleed off the excess air. Then reset it
by turning in the air regulator knob.
