WARNING
A red-handled bleed-type master air valve (E) is
required in your system to 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 adjusting or repairing the pump.
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.
D The red-handled bleed-type master air valve (E)
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 air filter/regulator
(G). Order Part No. 113329 Bleed Valve (supplied
with Model 205585).
D The air filter/regulator (G) controls pump speed
and outlet pressure by adjusting the air pressure to
the pump and the air spray gun. It also removes
harmful dirt and moisture from the compressed air
supply. Locate the pump air filter/regulator upstream from the bleed-type master air valve (E).
Also, supply an air filter/regulator at each spray
booth.
Fluid Line Accessories
WARNING
A fluid drain valve (K) is required in your system to
help reduce the risk of serious injury, including
splashing of fluid in the eyes or on the skin.
The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose, and gun.

Pressure Relief Procedure
Packing Nut
WARNING
PRESSURIZED EQUIPMENT HAZARD
The system pressure must be manually relieved to
prevent the system from starting or spraying accidentally. To reduce the risk of an injury from accidental spray from the gun, splashing fluid, or
moving parts, follow the Pressure Relief Procedure whenever you:
D
D
D
D
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
or install or clean the spray nozzle.
1. Close the red-handled bleed-type master air valve
(E, required in your system). Leave the pump air
valve (4) open.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
Check the tightness of the packing nut (106) periodically. The nut should be tight enough to prevent leakage. Do not overtighten the packing nut. Relieve
pressure before adjusting the nut.
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 12.
2. Close the pump restrictor valve (12).
3. Shut off the air to the agitator (if used).
Lubrication
4. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
If you are not using an accessory air line lubricator,
manually lubricate the motor daily. Disconnect the air
line at the pump air inlet, place about 15 drops of light
machine oil in the pump air inlet, reconnect the air line
and turn on the air supply to blow air into the motor.
5. Open the drain valve (required in your system),
having a container ready to catch the drainage.
6. Leave the drain valve open until you are ready to
spray again.
If you suspect that the spray nozzle or hose is completely clogged, or that pressure has not been fully
relieved after following the steps above, very slowly
loosen the nozzle retaining ring or hose end coupling
and relieve pressure gradually, then loosen completely.
Now clear the nozzle or hose.

WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your system, which could cause component rupture and serious injury, never
exceed the specified Maximum Incoming Air Pressure to the pump (see the Technical Data, on
page 22).
9. Slowly open the pump air valve (4) until the pump
starts. Use the air valve to control pump speed
and fluid pressure. Always use the lowest pressure
necessary to get the desired results. Higher pressures cause premature nozzle and pump wear.
10. Cycle the pump slowly until all air is pushed out
and the pump and hoses are fully primed.
11. Release the gun trigger and lock the trigger safety.
The pump should stall against pressure.
12. With the pump and lines primed, and with adequate air pressure and volume supplied, the pump
will start and stop as you open and close the gun.
WARNING

lower locknut (39) from the return tube (64). Disconnect the union (30) from the supply tube (62).
Remove the cotter pin (27) to free the upper end of
the connecting rod (63). Remove the cotter pin
from the lower end of the connecting rod and
unscrew the rod from the displacement rod (111).
See Detail A of Fig. 9.
2. Unscrew the cylinder (110*) from the outlet housing (112). If the displacement rod (111) is seized by
dried fluid, soak in a compatible solvent before
disassembling; do not try to break loose by twisting the rod.
3. Unscrew the packing nut (106) and remove the
bearing (113*), packing (114*), and o-ring (115*).
Clean and inspect all parts for wear or damage
and replace if necessary.
4. Make sure that all parts are completely free of
paint fillers and pigments. Fill the displacement rod
cavity with heavy grease and reassemble in the
reverse order of disassembly.
5. When reconnecting the displacement pump to the
air motor, first tighten the union (30) onto the
supply tube (62), then screw the upper nut (39) on
the return tube down to the outlet housing (112)
and lock in place with the lower lockwasher (25)
and nut (39).
