Air Line and Accessory
Recommendations
Fluid Line and Accessory
Recommendations
1. Install an air pressure regulator on the gun cylinder
air supply line.
•
A fluid drain valve(s) is required in your system to
assist in relieving fluid pressure in the displacement
pump, hose and gun; triggering the gun to relieve
pressure may not be sufficient.
A minimum of 70 psi (0.49 MPa, 4.9 bar) air pres-
sure must be supplied to the cylinder for proper
operation. Air pressure opens the valve, a spring
closes the valve. A three-way air valve, which
exhausts cylinder air, is required.
•
A fluid pressure regulator must be installed in the
system if the pump's maximum working pressure
exceeds the gun's maximum fluid working pressure
(see the front cover).
2. Install a bleed-type air shutoff valve on the main air
line. Install an additional bleed-type valve on each
pump air supply line, downstream of the pump air
regulator, to relieve air trapped between this valve
and the pump after the air regulator is shut off.
1. Install a fluid filter and drain valve(s) close to the
pump's fluid outlet.
2. Install a fluid pressure regulator to control fluid pres-
sure to the gun.
The bleed-type air shutoff valve is required in your sys-
tem to relieve air trapped between this valve and the
pump after the air regulator is closed. Trapped air can
cause the pump to cycle unexpectedly, which could
result in serious injury.
Some applications require fine-tuned control of fluid
pressure. You can control fluid pressure more accu-
rately with a fluid pressure regulator than by regu-
lating the air pressure to the pump.
3. Install a bleed-type air shutoff valve on the gun air
cylinder supply line, downstream of the air regulator,
to shut off air to the gun cylinder. Connect the air
supply line to the gun cylinder air inlet (C). See Fig.
4.
3. Install a fluid shutoff valve to shut off the fluid supply
to the gun.
4. For paint spray applications, install an in-line fluid fil-
ter, part no. 210500, on the gun fluid inlet (F) to
avoid clogging the spray tip with particles from the
fluid. See Fig. 4.
The cylinder air inlet accepts 1/4 in. (6.3 mm) O.D.
tubing.
5. Connect the electrically conductive fluid hose to the
gun fluid inlet (F) or optional in-line filter.

Setup
Flush Spray Gun
Adjust Spray Pattern
Before running any paint through the spray gun:
1. To adjust the spray pattern direction with fan tips,
orient the slot in the tip horizontally for a horizontal
pattern and vertically for a vertical pattern. See Fig.
7.
1. Flush the gun with a solvent that is compatible with
the fluid to be sprayed, using the lowest possible
fluid pressure and grounded metal container.
2. Start the pump. Adjust the fluid pressure until the
spray is completely atomized. Use the lowest pres-
sure necessary to get the desired results. Higher
pressure may not improve the spray pattern and will
cause premature tip wear and pump wear.
Install Spray Tip
3. The spray tip orifice and spray pattern angle deter-
mines the coverage and size of pattern. When more
coverage is needed, follow the Pressure Relief
rather than increasing fluid pressure.
2. Install the spray tip (H) and the gasket (J) in the tip
retainer nut (K). Screw the assembly firmly onto the

Operation
Operation
Pressure Relief Procedure
Apply the Fluid
Adjust the system control device, if it is automatic, so the
gun starts spraying just before meeting the workpiece
and stops as soon as the workpiece has passed. Keep
the gun a consistent distance, 8 to 10 in. (200 to 250
mm), from the surface of the object being sprayed.
1. Shut off the power to the pump.
To achieve best results when applying fluid:
2. Turn off the air and fluid supply to the gun.
3. Close the bleed-type master air valve (required in
the system).
•
•
Keep gun perpendicular and 8 to 10 inches (200 to
250 mm) from object being sprayed.
4. Trigger the gun into a grounded metal waste con-
tainer to relieve the fluid pressure.
Use smooth, parallel strokes across surface to be

FIG. 9: Pressure Relief
5. Open the pump drain valve (required in the system)
to help relieve fluid pressure in the displacement
pump. In addition, open the drain valve connected to
the fluid pressure gauge (in a system with fluid regu-
lation) to help relieve fluid pressure in the hose and
gun. Triggering the gun to relieve pressure may not
be sufficient. Have a container ready to catch the
drainage.
TI8098a
Correct
6. Leave the drain valve(s) open until you are ready to
spray again.
7. If you suspect that the spray tip or hose is com-
pletely clogged or that pressure has not been fully
relieved after following the steps above, very slowly
loosen the hose end coupling and relieve pressure
gradually, then loosen the coupling completely. Now
clear the tip or hose obstruction.
