system is compatible with the paint that is going to be used.
i
Incompatible uids and paint may cause the valves
to become stuck closed, which would require
disassembly and cleaning of the sprayer’s uid
section.
Always keep the trigger lock on the spray gun in the
locked position while preparing the system.
1. Place the siphon tube into a container of the appropriate
solvent for the material being sprayed.
i
If you are spraying a water-based latex, ush with
warm, clean water. If you are using any other
material, check with the material manufacturer for a
compatible solvent.
2. Place the bleed hose into a metal waste container.
3. Close the shuto valve (g 11, item 1). The gure 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.
7. Open the shuto valve (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 solvent ows freely from the
bleed hose.
9. Allow the sprayer to run for 15–30 seconds to ush the test
uid out through the bleed hose and into the waste container.
10. Turn o the sprayer.
a. Turn the air regulator fully counterclockwise to its lowest
pressure setting.
b. Close the shuto valve.
Make sure that the spray gun does not have a tip or
tip guard installed.
11. Close the bleed valve by turning it fully clockwise.
12. Open the shuto valve (1). The handle should now be in line
with the valve. The system is now under pressure.
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).
i
The air regulator can be locked into place by pushing
down on the knob. Unlock the regulator by pulling
the knob out.
14. Unlockthegunbyturningtheguntriggerlocktothe
unlocked position.
Earth 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.
4.3 Preparing a New Sprayer
If this unit is new, it is shipped with test uid in the uid section to
prevent corrosion during shipment and storage. This uid must be
thoroughly cleaned out of the system with cleaning agent before you
begin spraying.
Always keep the trigger lock on the spray gun in the
locked position while preparing the system.
1. Place the siphon tube into a container of mineral spirits.
2. Place the bleed hose into a metal waste container.
3. Close the shuto valve (g 11, item 1). The gure 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.
