Spraying

1. Place the siphon hose into a container of paint.
2. Place the bleed hose into a metal waste container.
3. Close the shutoff valve (fig. 12, item 1). The figure shows the
handle in the closed position.
4. Turn on the air compressor.
5. Turn the air regulator (2) fully counterclockwise to its lowest
pressure setting.
6. Open the bleed valve (3) by turning it fully counterclockwise.
The bleed valve handle should be pointing down.
7. Open the shutoff valve (fig. 12, item 1). The handle should
now be in line with the valve.
8. Turn the air regulator (2) clockwise to increase pressure until
the sprayer cycles evenly and material flows freely from the
bleed hose.
9. Turn off the sprayer.
a. Turn the air regulator fully counterclockwise to its lowest
pressure setting.
b. Close the shutoff valve.
10. Remove the bleed hose from the waste container and place it
into the container of material.
11. Close the bleed valve by turning it fully clockwise.
12. Open the shutoff valve. The handle should now be in line
with the valve.
13. Turn the air regulator clockwise to increase pressure until the
sprayer cycles evenly. The air regulator gauge should read
between 60-80 PSI (4 - 5.5 bar).
14. Unlock the gun by turning the gun trigger lock to the
unlocked position.
Earth (ground) the gun by holding it against the
edge of the metal container while flushing. Failure
to do so may lead to a static electric discharge, which
may cause a fire.
15. Trigger the gun into the metal waste container until all air and
solvent is flushed from the spray hose and paint is flowing
freely from the gun.
16. Lock the gun by turning the gun trigger lock to the locked
position.
17. Close the shutoff valve (fig 12, item 1). The figure shows the
handle in the closed position.
18. Attach tip guard and tip to the gun as instructed by the tip
guard or tip manuals.
POSSIBLE INjECTION HAZARD. Do not spray
without the tip guard in place. Never trigger the
gun unless the tip is in either the spray or the unclog
position. Always engage the gun trigger lock before
removing, replacing or cleaning tip.
19. Open the shutoff valve. The handle should now be in line
with the valve.
20. Increase the pressure by turning the air regulator slowly
clockwise and test the spray pattern on a piece of cardboard.
Adjust the regulator until the spray from the gun is completely
atomized. Verify pressure reading at the air gauge.
• Paint pressure is directly proportional to the amount of air
pressure.
• Example: PowrCoat 630 = 30:1
100 PSI (6.9 bar) reading at air gauge = 3000 PSI (207 bar) at
pump outlet
DO NOT exceed an air regulator gauge reading of
116 PSI (8.0 bar).

21. Once the correct air pressure has been established, lock the air
regulator by pushing down on the knob.
using a higher pressure than required will only
i
wear out tips. use the guidelines in establishing the
lowest pressures for proper atomization.
Consult the materials manufacturer for guidelines in
establishing the correct fluid pressure.

Pressure Relief Procedure

Be sure to follow the Pressure Relief Procedure when
shutting the unit down for any purpose, including
servicing or adjusting any part of the spray system,
changing or cleaning spray nozzles, or preparing for
cleanup.
1. Lock the spray gun by turning the gun trigger lock to the
locked position.
2. Close the shutoff valve.
3. Open the bleed valve by turning it fully counterclockwise.
4. Unlock the gun by turning the gun trigger lock to the
unlocked position.
5. Hold the metal part of the gun firmly to the side of a metal
waste container to earth the gun and avoid a build up of static
electricity.
6. Trigger the gun to remove any pressure that may still be in the
hose.
7. Lock the gun by turning the gun trigger lock to the locked
position.
