lubrication of the air motor.
Refer to Fig. 2 on page 9.
D The air relief valve (11j) opens automatically to
prevent overpressurization of the pump.
WARNING
D Fluid is supplied to the pump through the suction
hose (16) and tube (50). See Fig. 2.
A red-handled bleed-type master air valve (11h)
and a fluid drain valve (D) are supplied. These
components help reduce the risk of serious injury,
including splashing of fluid in the eyes or on the
skin, and injury from moving parts if you are adjust-
ing or repairing the pump.
D The fluid filter (5) includes a 60 mesh (250 mi-
cron) stainless steel element to filter particles from
the fluid as it leaves the pump.
D The fluid drain valve (D), is mounted in the bot-
tom of the fluid filter bowl, and is required in your
system to relieve fluid pressure in the hose and gun
(see the WARNING at left).
The bleed-type master air valve relieves air trapped
between this valve and the pump after the air is
shut off. Trapped air can cause the pump to cycle
unexpectedly. Locate the valve close to the pump.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient.
D The back pressure regulator (12) controls back
pressure to the gun and maintains proper circula-
tion pressure.
Conversion Modules
D The red-handled bleed-type master air valve
(11h) is required in your system to relieve air
trapped between it and the air motor when the
valve is closed (see the WARNING above). Be sure
the bleed valve is easily accessible from the pump,
and is located downstream from the pump air
filter/regulator (11a).

WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
1. Close the red-handled bleed-type master air valve
(11h, required in your system). See Fig. 4 on page
13.
The packing nut is torqued at the factory and is ready
for operation. If it becomes loose and there is leaking
from the throat packings, relieve pressure, then torque
the nut to 34–40 NSm (25–30 ft-lb). Do this whenever
necessary. Do not overtighten the packing nut.
2. Place the drain hose (42) into a waste container.
Turn the 3-way recirculation valve (19) to the drain
position.
3. Trigger the gun at the last gun station to relieve
fluid pressure. Maintain firm metal-to-metal contact
between the gun and a grounded waste pail.
Repeat for all gun stations.
Flush the Pump Before First Use
The pump is tested with lightweight oil, which is left in
to protect the pump parts. If the fluid you are using
may be contaminated by the oil, flush it out with a
compatible solvent. See Flushing on page 14.

component rupture and serious injury,
never exceed the specified maximum air input
pressure to the pump (see Technical Data on
page 20).
3. Open the spray gun at the last gun station and
keep it open while starting the pump.
CAUTION
4. Open the bleed-type master air valves (11h, B).
Do not allow the pump to run dry. It will quickly
accelerate to a high speed, causing damage. If your
pump is running too fast, stop it immediately and
check the fluid supply. If the container is empty and
air has been pumped into the lines, refill the con-
tainer and prime the pump and the lines, or flush and
leave it filled with a compatible solvent. Eliminate all
air from the fluid system.
5. Slowly open the air filter/regulator (11a) until the
pump starts. The air filter/regulator controls the
pump speed and fluid outlet pressure.
6. Adjust the fluid pressure to the lowest setting
necessary to get the desired results. Higher pres-
sures may not improve the spray pattern and will
cause premature component wear. Use the air
filter/regulator (11a) and the back pressure regula-
tor (12) to adjust the pump speed and fluid pres-
sure until the spray is completely atomized. Refer
to the back pressure valve manual (supplied) for
adjustment procedures.
Shutdown
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 11.
7. To adjust the spray pattern, follow the complete
instructions in your gun manual.
Relieve the pressure.
8. When you have achieved the desired spray pat-
tern, release the gun trigger. The pump will contin-
ue to cycle as long as air is supplied and the back
pressure regulator (12) is open.
For overnight shutdown, stop the pump at the bottom
of its stroke to prevent fluid from drying on the ex-
posed displacement rod and damaging the throat
packings. Relieve the pressure.
9. One at a time, open any other guns in the system
to purge air from the lines.
Always flush the pump before the fluid dries on the
displacement rod. See Flushing on page 14.
NOTE: In a circulating system, the pump will continue
to cycle as long as air is supplied and the back pres-
sure regulator is open. In a direct supply system, the
pump starts when the gun is opened, and stops when
the gun is closed.
NOTE: When changing fluid containers with the hose
and gun already primed, open the drain valve (D) to
help prime the pump and vent air before it enters the
hose. Close the drain valve when all air is eliminated.
