HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read and understand all instruction manuals before operating equipment.
FLU/D /NJECT/ON HAZARD
WARNING
General Safety
This eauipment aenerates very high fluid pressure. Sprav from
the gun; leaks-or ruptured. components can inject fluid
through your skin and into your body and cause extremely
serious bodily injury, including the need for amputation. Also,
fluid injected or splashed into the eyes or on the skin can
cause serious damage.
NEVER point the spray gun or dispensing valve at anyone or at
any part of the body. NEVER put hand or fingers over the
spray tip or nozzle. NEVER try to “blow back” paint; this is
NOT an air spray system.
ALWAYS have the tip guard in place on the spray gun when
spraying.
ALWAYS follow the Pressure Relief Procedure, below,
before cleaning or removing the spray tip or nozzle or servicing
any system equipment.
NEVER try to stop or deflect leaks with your hand or body.
Be sure the equipment safety devices are operating properly
before each use.
Medical Alert -Airless Spray Wounds
If any fluid appears to penetrate your skin, get
MEDICAL CARE AT ONCE. DO NOT TREAT AS A
SIMPLE CUT. Tell the doctor exactly what fluid was injected.
Note to Physician:
jury. It is important to treat the injury surgically as soon
as
possible. Do not delay treatment to research toxicity.
Toxicity is a concern with some exotic coatings injected
directly into the blood stream. Consultation with a plastic
surgeon or reconstructive hand surgeon may be advisable.
Pressure Relief Procedure
To reduce the risk of serious bodilv iniury, includinq fluid iniection, splashing in the eyes or on the skin, or injury from moving parts, always follow this procedure whenever you shut off
the pump, when checking or servicing any part of the spray
system, when installing, cleaning or changing spray tips or
nozzles, and whenever you stop spraying.
Engage the gun safety latch.
::
Shut off the air to the motor.
Close the bleed-type master air valve (required).
::
Disengage the gun safety latch.

again.
If you suspect that the spray tip/nozzle or hose is completely
clogged, or that pressure has not been fully relieved after
following the steps above, VERY SLOWLY loosen the retain-
ing nut or hose end coupling and relieve pressure gradually,
then loosen completely. Now clear the tip or hose obstruction.

EMERGENCY
Spray Gun and Dispensing Valve Safety Devices
Be sure all gun or dispensing valve safety devices are
operating properly before each use. Do not remove or modify
any part of the gun or dispensing valve; this can cause a
malfunction and result in serious bodily injury.
Safety Latch
Whenever you stop spraying, even for a moment, always set
the oun or dispensina valve safetv latch in the closed or “safe”
po&on, making the gun or dispensing valve inoperative.
Failure to set the safety latch can result in accidental triggering
of the gun or dispensing valve.
Diffuser /only on spray guns)
The gun diffuser breaks up spray and reduces the risk of fluid
injection when the tip is not installed. Check the diffuser
operation regularly. Follow the Pressure Relief Procedure,
at the left, then remove the spray tip. Aim the gun into a
grounded metal pail, holding the gun firmly to the pail. Using
the lowest possible pressure, trigger the gun. If the fluid emit-
ted is not diffused into an irregular stream, replace the diffuser
immediately.
Tip Guard (only on spray guns)
ALWAYS have the tip guard in place on the spray gun while
spraying. The tip guard alerts you to the fluid injection hazard
and helps reduce, but does not prevent, the risk of accidental-
ly placing your fingers or any part of your body close to the
spray tip.
Trigger Guard (only on spray guns)
NEVER operate the gun with the trigger guard removed. The
trigger guard reduces the risk of accidentally triggering the
gun if it is dropped or bumped.
Spray Tip and Nozzle Safety
Use extreme caution when cleaning or changing spray tips or
nozzles. If the sorav tip or nozzle clogs while spraying, engage
the gun or dispensing valve safety latc‘h immediately.
ALWAYS follow the Pressure Relief Procedure, at the left,
and then-remove the spray tip or nozzle to clean it.
NEVER wipe off build-up around the spray tip or nozzle until
pressure is fully relieved and the gun or dispensing valve safety
latch is engaged.
MOVlNG PARTS HAZARD
Moving parts can pinch or amputate your fingers or other
body parts. KEEP CLEAR of moving parts when starting or
operating the pump. Follow the Pressure Relief Procedure,
at the left, before checking or servicing the pump to prevent it
from starting accidentally. NEVER operate the motor with the
pump housing removed.
SUCTlON HAZARD
NEVER place your hands on or near the pump suction inlet.
Powerful suction could cause serious bodily injury.

EQUIPMENT MISUSE HAZARD
General Safety
Any misuse of the spray equipment or accessories, such as
overpressurizing, modifying parts, using incompatible fluids,
or using worn or damaged parts, can cause them to rupture
and result in fluid injection or other serious bodily injury, fire,
explosion or property damage.
NEVER alter or modify any part of this equipment; doing so
could cause it to malfunction.
CHECK all spray equipment regularly and repair or replace
worn or damaged parts immediately.
Read and follow the fluid and solvent manufacturer’s recommendations for use of protective clothing and equipment.
System Pressure
The 4-l/2:1 ratio pump can develop 450 psi (31 bar) MAX-
IMUM WORKING PRESSUREat 100 psi (7 bar) maximum incoming air pressure.
The 12:l ratio pump can develop 7200 psi (83 bar) MAXIMUM WORKING PRESSURE at 100 psi (7 bar) maximum incoming air pressure.
The 23:l ratio pump can develop 2300 psi (15.9 bar) MAXIMUM WORKING PRESSUREat 100 psi (7 bar) maximum incoming air pressure.
Be sure that all spray equipment and accessories are rated to
withstand the maximum working pressure of this pump. DO
NOT exceed the maximum working pressure of any component or accessory used in the system.
Fluid Compatibility
BE SURE that all fluids and solvents used are chemically com-
patible with the wetted parts shown in the TECHNICAL DATA
on the back cover. Always read the fluid manufacturer’s
literature before using them in this pump.
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If the
hose develops a leak, split or rupture due to any kind of wear,
damage or misuse, the high pressure spray emitted from it can
cause a fluid injection injury or other serious bodily injury or
property damage.
ALL FLUID HOSES MUST HAVE SPRING GUARDS ON
BOTH ENDS! The sorina auards helo orotect the hose from
kinks or bends at or &OS; 6 the cou&g which can result in
hose rupture.
TIGHTEN all fluid connections securely before each use. High
pressure fluid can dislodge a loose coupling or allow high
pressure spray to be emitted from the coupling.
NEVER use a damaged hose. Before each use, check the entire hose for cuts, leaks, abrasion, bulging cover, or damage or
movement of the hose couplings. If any of these conditions
exist, replace the hose immediately. DO NOT try to recouple
high pressure hose or mend it with tape or any other device. A
repaired hose cannot contain the high pressure fluid.
HANDLE AND ROUTE HOSES CAREFULLY. Do not pull on
the hoses to move the equipment. Do not use fluids which are
not compatible with the inner tube and cover of the hose. DO
NOT expose Grace hose to temperatures above 1WF W°C)
or below -40°F (-4O“C).
Hose Grounding Continuity
Proper hose grounding continuity is essential to maintaining a
grounded spray system. Check the electrical resistance of your
air and fluid hoses at least once a week. If your hose does not
have a tag on it which specifies the maximum electrical
resistance, contact the hose supplier or manufacturer for the
maximum resistance limits. Use a resistance meter in the ap-
propriate range for your hose to check the resistance. If the
resistance exceeds the recommended limits, replace it im-
mediately. An ungrounded or poorly grounded hose can make
your system hazardous. Also, read FIRE OR EXPLOSION
HAZARD, below.
F/f?E OR EXPLOSION HAZARD
Static electricity is created by the flow of fluid through the
pump and hose. If every part of the spray equipment is not
properly grounded, sparking may occur, and the system may
become hazardous. Sparking may also occur when plugging
in or unplugging a power supply cord. Sparks can ignite fumes
from solvents and the fluid being sprayed, dust particles and
other flammable substances, whether you are spraying indoors or outdoors, and can cause a fire or explosion and
serious bodily injury and property damage. Do not plug in or
unplug any power supply cords in the spray area when there is
any chance of igniting fumes still in the air.
If you experience any static sparking or even a slight shock
while using this equipment, STOP SPRAYING IMME-
DIATELY. Check the entire system for proper grounding. Do
not use the system again until the problem has been identified
and corrected.
Grounding
To reduce the risk of static soarkina, nround the Dump and all
other spray equipment used or l&%ed in the’ spray area.
CHECK your local electrical code for detailed grounding instructions for your area and type of equipment. BE SURE to
ground all of this spray equipment:
1. Pump: by connecting a ground wire and clamp to a true
earth ground. See the procedure on page 4.
2. Air and fluid hoses: use only grounded hoses with a maximum of 500 feet (150 m) combined hose lenath to ensure grounding continuity. Refer to Hose Giounding
Continuity, above.
3.

Pressure Relief Procedure
To reduce the risk of serious bodily injury, including fluid injection, splashing in the eyes or on
the skin, or injury from moving parts, always
follow this procedure whenever you
shut off
the
pump, when checking or servicing any part of the
spray system, when installing, cleaning or changing spray, tips or nozzles, and whenever you stop
spraying.
1. Engage the gun safety latch.
2. Shut
off the air to the motor.
3. Close the bleed-type master air valve
(required).
4. Disengage the gun safety latch.
5. Hold a metal part of the gun firmly to the side of
a grounded metal pail and trigger the gun to
relieve pressure.
6. Engage the gun safety latch.
7. Open the drain valve (required) and/or the
pump bleeder valve, having a container ready
to catch the drainage.
8. Leave the drain valve open until you are ready
to spray again.
If you suspect that the spray tip/nozzle or hose is
completely clogged, or that pressure has not been
fully relieved after following the steps above,
VERY SLOWLY loosen the retaining nut or hose
end coupling and relieve pressure gradually, then
loosen completely, Now clear the tip or hose
obstruction.
Flush the Pump Before Using
The pumps are tested with hydraulic oil, which is left in
to protect the pump parts. Read and follow Flushing
Safety under FIRE OR EXPLOSION HAZARD
on
page 3. Then flush the pump with a compatible solvent.
If the pump is being used in a circulating system, allow
the solvent to circulate long enough to thoroughly flush
the pump and the fluid lines.
Puma Start Up
1.
check and- service the lubricator, regulator, and
filter according to the instructions supplied with
them.
Open the bleed-type master air valves.
2.
Open the air regulator slowly. Adjust it until the
3.
pump runs smoothly.
4.
If you are using this pump to spray fluid, trigger the
gun to prime the hose. Adjust the pump pressure
just enough to completely atomize the fluid. Higher
pressures cause premature spray tip and pump
wear.
5.
Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a
high speed, possibly damaging itself. If your pump
accelerates quickly, or is running too fast, stop it
immediately and check the fluid supply. If the supply container is empty and air has been pumped into the lines, refill the container and prime the pump
and lines with the fluid, or flush and leave filled with
a compatible solvent. Be sure to eliminate all air
from the fluid system.
Pump Shutdown
1.
Close the bleed-type master air valves.
2.
If you are using a gun or a dispensing valve, relieve
the system pressure by following the Pressure
Relief Procedure Warning at the left. If you are
not using a gun or a dispensing valve, relieve the
system pressure by opening the fluid outlet valve.
3.
Always flush the pump before the fluid dries in it.
Read and follow Flushing Safety under FIRE OR
EXPLOSION HAZARD on page 3. If the pump is
to be stored for any period of time, and you are
pumping water-based fluid, first, flush the pump
with water and then with mineral spirits or a com-
patible solvent to protect the pump parts. Leave the
mineral spirits or an oil-based solvent in the pump
to prevent corrosion.
