SAFETY W ARNINGS
HIGH PRESSURE FLUID CAN CAUSE SERIOUS INJUR Y . FOR PROFESSIONAL USE ONL Y.
OBSERVE ALL W ARNINGS. Read And Understand All Instruction Manuals Before Operating Equipment.
FLUID INJECTION HAZARD
General Safety
This equipment generates very high fluid pressure. Spray from the spray
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 at anyone or at any part of the body . NEVER
put hand or fingers over the spray tip. NEVER try to “blow back” paint; this
is NOT an air spray system.
ALWA YS have the tip guard in place on the spray gun when spraying.
ALWAYS follow the Pressure Relief Procedure , right, before cleaning
or removing the spray tip or servicing any system equipment.
NEVER try to stop or deflect leaks with your hand or body .
Be sure equipment safety devices are operating properly before each
use.
Medical Alert––Airless Spray W ounds
If any fluid appears to penetrate your skin, get EMERGENCY MEDICAL
CARE A T ONCE. DO NOT TREA T AS A SIMPLE CUT . T ell the doctor
exactly what fluid was injected.
Note to Physician: Injection in the skin is a traumatic injury . It is im -
portant
to treat the injury surgically as soon as possible . Do not
delay treatment to research toxicity . T oxicity is a concern with some ex -
otic
coatings injected directly into the blood stream. Consultation with a
plastic surgeon or reconstructive hand surgeon may be advisable.
Spray Gun Safety Devices
Be sure all spray gun safety devices are operating properly before each
use. Do not remove or modify any part of the spray gun; this can cause a
malfunction and result in serious bodily injury .
Safety Latch
Whenever you stop spraying, even for a moment, always set the spray
gun safety latch in the closed or “safe” position, making the spray gun in -
operative.
Failure to set the safety latch can result in accidental triggering
of the spray gun.
Trigger Guard
Never operate the spray gun with the trigger guard removed. This guard
helps prevent the gun from triggering accidentally if it is dropped or
bumped.
Diffuser
The spray gun dif fuser breaks up spray and reduces the risk of fluid injec -
tion
when the tip is not installed. Check the dif fuser operation regularly .
Follow
the Pressure Relief Procedure , below , then remove the spray
tip. Aim the spray gun into a grounded metal pail, holding the spray gun
firmly to the pail. Using the lowest possible pressure, trigger the spray
gun. If the fluid emitted is not dif fused into an irregular stream, replace the
diffuser immediately .
Tip Guard
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 accidentally placing your fingers or any part
of your body close to the spray tip.
Spray T ip Safety
Use extreme caution when cleaning or changing spray tips. If the spray
tip clogs while spraying, engage the spray gun safety latch immediately .
ALWAYS
follow the Pressure Relief Procedure and then remove the
spray tip to clean it.
NEVER wipe of f build-up around the spray tip until pressure is fully re -
lieved
and the spray gun safety latch is engaged.
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 in -
stalling,
cleaning or changing spray tips, and whenever you stop
spraying.
1. Engage
the spray gun safety latch.
2. Shut of f the main power to the heater , if used. Circulate the fluid
for at least 10 minutes to allow it and the heater to cool.
3. Shut of f the air to the pump.
4. Close the bleed-type master air valve (supplied in your sys -
tem).
5. Disengage
the spray gun safety latch.
6. Hold a metal part of the spray gun firmly to the side of a
grounded
metal pail, and trigger the spray gun to relieve pres -
sure.
7. Engage
the spray gun safety latch.
8. Open the drain valve (supplied in your system), having a con -
tainer
ready to catch the drainage.
9. Leave the drain valve open until you are ready to spray again.
If you suspect that the spray tip or hose is completely clogged, or
that pressure has not been fully relieved after following the steps
above, VER Y SLOWL Y loosen the tip guard retaining nut or hose
end coupling and relieve pressure gradually, then loosen com-
pletely.
Now clear the tip or hose.
EQUIPMENT MISUSE HAZARD
General Safety
Any misuse of the spray equipment or accessories, such as
overpressurizing,
modifying parts, using incompatible chemicals and flu -
ids, or using worn or damaged parts, can cause them to rupture and result
in fluid injection, splashing in the eyes or on the skin, or other serious bod -
ily
injury , or 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 dam -
aged
parts immediately .
Always wear protective eyewear , gloves, clothing and respirator as rec -
ommended
by the fluid and solvent manufacturer .
System Pressure
The 30:1 ratio President pump can develop 3000 psi (210 bar) MAXIMUM
WORKING PRESSURE at 100 psi (7 bar) MAXIMUM INCOMING AIR
PRESSURE. NEVER exceed 100 psi (7 bar) air pressure to the pump.
Be sure that all spray equipment and accessories are rated to withstand
the maximum working pressure of the pump. DO NOT exceed the maxi -
mum
working pressure of any component or accessory used in the sys -
tem.
Fluid Compatibility
BE SURE that all fluids and solvents used are chemically compatible with
the wetted parts shown in the TECHNICAL DA TA on the back page or in
the separate component manuals. Always read the manufacturer ’s litera -
ture
before using fluid or solvent in this pump.

3307-928
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If the hose devel -
ops
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 spring guards help protect the hose from kinks or bends at or
close to the coupling 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 safely contain the high pressure
fluid.
HANDLE
AND ROUTE HOSES CAREFULL Y . Do not pull on hoses to
move equipment. Do not use fluids or solvents which are not compatible
with the inner tube and cover of the hose. DO NOT expose Graco hoses
to temperatures above 180  F (82  C) or below –40  F (–40  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 speci -
fies the maximum electrical resistance, contact the hose supplier or
manufacturer for the maximum resistance limits. Use a resistance meter
in the appropriate range for your hose to check the resistance. If the resis -
tance
exceeds the recommended limits, replace it immediately . An un -
grounded
or poorly grounded hose can make your system hazardous.
Also, read FIRE OR EXPLOSION HAZARD , below .
MOVING P ARTS HAZARD
The piston in the air motor , located behind the air motor plates, moves
when air is supplied to the motor . Moving parts can pinch or amputate
your fingers or other body parts. Therefore, NEVER operate the pump
with the air motor plates removed. KEEP CLEAR of moving parts when
starting or operating the pump. Before checking or servicing the pump or
any system component, follow the Pressure Relief Procedure on page
2, to prevent the pump from starting accidentally .
FIRE 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 out -
doors,
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, ST OP SPRA YING IMMEDIA TELY. Check the entire sys -
tem
for proper grounding. Do not use the system again until the problem
has been identified and corrected.
Grounding
To reduce the risk of static sparking, ground the pump, object being
sprayed,
and all other spray equipment used or located 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: use a ground wire and clamp as shown in Fig 1.
2. Air hoses: use only grounded air hoses.
3. Fluid hoses: use only grounded fluid hoses.
4. Heater (if used): refer to the V iscon Heater manual, 307–805.
5. Air compressor: follow manufacturer ’ s recommendations.
6. Spray gun: grounding is obtained through connection to a properly
grounded fluid hose and pump.
7. Fluid supply container: according to your local code.
8. Object being sprayed: according to your local code.
9. All solvent pails used when flushing, according to local code. Use
only metal pails, which are conductive, placed on a grounded sur -
face.
Do not place the pail on a nonconductive surface, such as pa -
per
or cardboard, which interrupts the grounding continuity .
10.
T o maintain grounding continuity when flushing or relieving pres -
sure
, always hold a metal part of the spray gun firmly to the side of a
grounded metal pail, then trigger the spray gun.
To ground the pump:
To ground the pump, loosen the grounding lug locknut (W) and
washer
(X). Insert one end of a 1.5 mm  (12 ga) minimum ground
wire (Y) into the slot in lug (Z) and tighten the locknut securely . See
Fig 1. Refer to page 19 to order a ground wire and clamp. Connect the
other end of the ground wire to a true earth ground.
