EQUIPMENT MISUSE HAZARD
Equipment misuse can cause the equipment to rupture, malfunction, or start unexpectedly and result
in serious injury.
This equipment is for professional use only.
Read all instruction manuals, tags, and labels before operating the equipment.
l
Use the equipment only for its intended purpose. If you are in doubt about this, call your
distributor.
Do not alter or modify this equipment. Use only genuine
parts and accessories.
Check equipment daily. Repair or replace worn or damaged parts immediately.
Do not exceed the 100 psi (6.9 bar) maximum working pressure at 100 psi (6.9 bar) maxi-
mum incoming air pressure of the package or the maximum working pressure of any accesso-
ry used with it.
Do not move or lift pressurized equipment.
Use fluids or solvents that are compatible with equipment wetted parts. See the Technical Data
section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings.
Fluid hoses must have spring guards on both ends to protect them from rupture caused by kinks
or bends at or close to the couplings.
Comply with all applicable local, state, and national fire, electrical, and other safety regulations.
TOXIC FLUID HAZARD
Improper handling of hazardous fluids or inhaling toxic fumes can cause extremely serious injury or
death from splashing in the eyes, ingestion, or bodily contamination.
l
l
Know the specific hazards of the fluid you are using.
Store hazardous fluid in an approved container. Dispose hazardous fluid according to all local,
state, and-national guidelines.
l
l
Wear appropriate clothing, gloves, eyewear, and respirator.
.
If the pump diaphragm fails, hazardous fluid may be exhausted along with the air. See your sepa-
rate pump manual for further information.

3 . Connect the whip hose (10) to the fluid inlet of the
spray gun (2).
Unpacking the System
In addition to the assembled unit, these components
are packed loosely or separately: suction assembly,
hose set, gun, instruction manuals. These are the
manuals you should receive:
4. Verify that all fittings throughout the system are
tightened securely.
5 . Use a tie strap (58) to secure the hose set to the
leg of the cart. This provides strain relief so that
tugs on the heavy hoses don’t damage the hose
connections.

System Component Information
VI. Using the
Air Spray Gun
Refer to Fig. 3.
1 . Make initial fluid and air adjustments at the pump
for maximum efficiency.
2 . If you make adjustments at the gun, take noted of
what you do. Then, if the results are not satisfac-
tory, you can easily return the gun to its previous
adjustment. Steps 3 and 4 explain the gun adjust-
ments.
3 . Fan pattern adjusting valve (E). Normal adjust-
ment is the valve turned out fully clockwise and
then turned IN two full turns.
a . Turn counterclockwise to widen spray pattern.
b . Turn clockwise to narrow spray pattern.

4 . Fluid adjusting valve (F). This valve is used in sys-
tems that do not have a fluid regulator. For this
system, use the fluid regulator to adjust fluid flow.
Air cap horns shown horizonta
which produces a vertical

5 . The gun has a built-in lead and lag operation.
When triggered, the gun emits air before the fluid
is discharged. When the trigger is released, the
fluid stops before the air flow stops. This helps as-
sure the spray is atomized and prevents fluid buil-
dup on the air cap.

not over-tighten. See Fig. 4 for how to obtain a ver-

The heater (3) used in this system is a high mass
heater. Always circulate the fluid when the heater is
operating to prevent overheating and damaging the
fluid. Do not use catalyzed material in this heater.
7 . Clean and lubricate the gun as instructed in the
separate gun manual, 307-452.

Valve
VIII. Using the Air Regulators and Needle
See Fig. 5.
1 .
Always open air and fluid regulators slowly to pre-
vent surging during startup.
Heated systems require that the fluid circulate
constantly when the heater is turned on. The
valve (9) supplied with this system enables you to
drain or circulate the fluid. The words Drain and Circu-
late are marked on the valve.
The air regulator (6a) on the right side of the pump
controls air to the pump, and the regulator (6b) on
the left side controls air to the gun.
2 . To open the air regulator, pull out the adjusting
knob. Turn the knob IN (clockwise) to open, and
turn the knob fully OUT (counterclockwise) to
close. You may push the adjusting knob in to lock
the adjustment.
In the Drain position, and with the gun untriggered,
the fluid returns from the gun, to the needle valve
to the hose
and to the 3-way valve, which
directs the fluid out the drain hose (13). This posi-
tion is used when flushing the system and when
relieving system pressure.
3 . The fluid regulator (44) controls fluid from the
pump to the gun. For an accurate setting, adjust
the fluid regulator only when the gun is triggered,
and fluid is flowing through the regulator. Be sure
the jam nut (H) under the T-handle does not inter-
fere with your adjustments. Tighten the jam nut to
lock in the setting, if desired.
In the Circulate position, with the gun untriggered,
fluid returns from the gun, to the needle valve
to the hose
and to the 3-way valve, which
directs the fluid back into the pump intake. This
position is used during normal operation, and it
helps keep the fluid at a constant temperature.
4.
To open the fluid regulator, which allows fluid to
flow, turn the T-handle IN (clockwise).
5 . The needle valve
located on the fluid return
side of the circulating system, acts as a flow con-
trol. Use it to balance the pressure of the circulat-
ing fluid so that the pump circulates a sufficient
volume of fluid without running too fast or too slow.
Trigger the gun while adjusting the needle valve.
Turn the needle valve handle IN (clockwise) to
restrict fluid and slow down the pump. Turn the
needle valve handle OUT (counterclockwise) to
allow more flow, which. speeds up the pump.
A
CAUTION
Never close the needle valve completely. Doing so
prevents circulation, which can cause the fluid to
overheat, damaging the fluid and the heater.

to 20 to 30 psi (1.4 to 2.1 bar). The pump will cycle
quickly until is it primed. When it is primed, the
pump will stall against pressure. Now set the pump
air pressure to 40 psi (2.8 bar). When fluid flows
from the drain hose, turn the 3-way valve to Circu-
late.
II.
Flush the Pump Before First Use
Flush with a solvent compatible to your fluid. Consult
the fluid manufacturer’s literature for recommenda-
tions. See Flushing on page IO.
11. Hold the gun against and aimed into a grounded
metal waste pail. Trigger the gun, and slowly open
the fluid regulator (44). The gun will emit air until
the fluid arrives. When fluid flows freely, release
the gun trigger.
Priming the System
See Fig. 7.
Put the suction tube (15) in the prepared fluid.

Be sure the fluid is circulating whenever the heater
is on to reduce the risk of damage to the fluid or
the heater.
3 . Be sure the gun’s fan pattern adjusting valve (E)
has been turned OUT fully clockwise and then
turned IN two full turns. See Fig. 9.
14. Follow the fluid manufacturer’s recommendations
for temperature, and adjust the heater accordingly.
If unknown, set the temperature to 110°F (43°C)

6 . Spray a stationary test pattern on scrap paper.
Hold the gun 10 to 12 in. (250 to 300 mm) from the
paper, and spray for 2 or 3 seconds. If the spray
pattern is poorly atomized, you may need to adjust
the air or fluid pressure.
IV. Setting Fiuid and Air Pressure
With the system primed, the gun regulator (6b)
closed, and the pump air regulator (6a) set as
instructed in Step 10 on page 8, adjust the fluid
pressure regulator (44) to the fluid manufacturer’s
specifications, if available. Otherwise, follow Step
2 to determine the fluid pressure setting.
If the spray pattern atomization is not fine enough,
increase the gun air pressure. If the spray pattern
atomization is too fine, decrease the gun air pres-
sure. If the atomization is still not good enough, try
lowering the fluid pressure in increments of 2 or 3
psi to achieve the desired finish quality.
.
2. To determine the fluid pressure setting, hold the
gun parallel to the floor. (Be sure to catch the fluid
in a container.) With the gun air pressure turned
NOTE: For the most efficient paint usage, use the
lowest air pressure needed to obtain a good finish.
Higher air pressures create more overspray and
uses more fluid.

ulator (4) until the straight fluid stream is within the
range indicated for the viscosity of your fluid before
it drops off. See Fig. 8. Make note of the pressure

setting.

tune the spray pattern. Turn counterclockwise
