WARNINGS
High Pressure Spray Can Cause Serious Injury . For Professional Use Only.
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 ex -
tremely serious bodily injury , including the need for amputa -
tion. 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.
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 at once. Do not treat as a simple cut. T ell the
doctor exactly what fluid was injected.
NOTE TO PHYSICIAN: Injection into the skin is a traumatic
injury. It is important to treat the injury surgically as soon
as possible. Do not delay treatment to research toxicity . T ox-
icity 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.
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 inoperative. Failure to set the safety
latch can result in accidental triggering of the spray gun.
Diffuser
The spray gun dif fuser breaks up spray and reduces the risk
of fluid injection when the tip is not installed. Check the dif -
fuser operation regularly . Follow the Pressure Relief Proce -
dure,
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 dif fuser 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 acciden -
tally placing your fingers or any part of your body close to the
spray tip.
Trigger Guard
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 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, below , and then remove the spray tip to clean it.
Never wipe of f build-up around the spray tip until pressure is
fully relieved and the spray gun safety latch is engaged.
Pressure Relief Procedure
To reduce the risk of serious bodily injury , including fluid injec -
tion, splashing in the eyes or on the skin, or injury from mov -
ing parts, always follow this procedure whenever you shut of f
the pump, when checking or servicing any part of the spray
system, when installing, cleaning or changing spray tips, and
whenever you stop spraying.
1. Engage the spray gun safety latch.
2. Shut of f the air to the pump.
3. Close the bleed-type master air valve (required in your
system).
4.
Disengage the spray gun safety latch.
5. Hold a metal part of the spray gun firmly to the side of a
grounded metal pail, and trigger the spray gun to relieve
pressure.
6.
Engage the spray gun safety latch.
7. Open the drain valve (required in your system), to relieve
pressure in the fluid hose and gun. T riggering the gun to
relieve pressure may not be suf ficient. Have 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 or hose is completely
clogged, or that pressure has not been fully relieved after
following the steps above, very slowly loosen the tip guard
retaining nut or hose end coupling and relieve pressure
gradually , then loosen completely . 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 chemi -
cals and fluids, 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 bodily injury , or fire, ex -
plosion 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 .
Always wear protective eyewear
, gloves, clothing and respi -
rator as recommended by the fluid and solvent manufacturer .
System Pressure
Refer to the T echnical Data on page 19 for specific fluid and
air working pressures. Never exceed the maximum fluid or air
working pressure. Be sure that all spray equipment and ac -
cessories are rated to withstand the maximum working pres -
sure of this sprayer
. Do not exceed the maximum working
pressure of the lowest rated 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 T echnical Data on
page 19 and in the separate pump and component manuals.
Always read the manufacturer ’ s literature before using fluid or
solvent in this pump.
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 parti -
cles and other flammable substances, whether you are
spraying indoors or outdoors, and can cause a fire or explo
-
sion 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 immediately .
Check the entire system for proper grounding. Do not use the
system again until the problem has been identified and cor -
rected.
Grounding
T o 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 compressor: follow manufacturer ’ s recommendations.
3. Air and fluid hoses: use only grounded hoses with a
maximum of 500 feet (150 m) combined hose length to
ensure grounding continuity . Refer also to HOSE SAFE-
TY.
4.
Spray gun: grounding is obtained through connection to
a properly grounded fluid hose and pump.
5. Object being sprayed: according to your local code.
6. Fluid supply container: according to your local code.
7. All solvent pails used when flushing, according to local
code. Use only metal pails, which are conductive, placed
on a grounded surface. Do not place the pail on a non -
conductive surface, such as paper or cardboard, which
interrupts the grounding continuity .
8.
T o maintain grounding continuity when flushing or reliev -
ing pressure , 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) mini -
mum ground wire (Y) into the slot in lug (Z) and tighten the
locknut securely . See Fig. 1. Connect the other end of the
wire to a true earth ground. See Accessories on page 13.

Flushing Safety
Before flushing, be sure the entire system and flushing pails
are properly grounded. Refer to Grounding , at the left. Fol -
low the Pressure Relief Procedure on page 3, and remove
the spray tip from the spray gun. Always use the lowest pos-
sible fluid pressure, and maintain firm metal-to-metal contact
between the spray gun and the pail during flushing to reduce
the risk of fluid injection injury , static sparking and splashing.

5306-787
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 spring guards help protect the hose from kinks or bends
at or close to the coupling which can result in hose rupture.
T ighten 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 en -
tire 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 carefully . Do not pull on hoses to
move equipment. Do not use fluids 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 specifies the maximum elec -
trical 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 resistance exceeds the recommended limits, replace it
immediately . An ungrounded or poorly grounded hose can
make your system hazardous. Also, read FIRE OR EXPLO-
SION HAZARD
on page 4.
MOVING P ARTS HAZARD
The piston in the air motor , located behind the air motor
shield, 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 shield
removed. Keep clear of moving parts when starting or operat -
ing the pump. Before checking or servicing the pump or any
system component, follow the Pressure Relief Procedure
on page 3 , to prevent the pump from starting accidentally .
IMPORTANT
United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards
– particularly the General Standards, Part 1910, and the Construction Standards, Part 1926 – should be consulted.

WARNING
A bleed-type master air valve (K) and a fluid drain
valve (B) are supplied in your system. These com -
ponents help reduce the risk of serious bodily injury
including fluid injection, splashing 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 of f. T rapped 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 pump, hose, and gun. T riggering the
gun to relieve pressure may not be suf ficient.
Supplied Components
The following components are supplied with your
pump:

The bleed-type master air valve (K) 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 easi -
ly accessible from the pump, and is located down-
stream
from the air regulator .
The pump
air regulator (F) controls pump speed
and outlet pressure by adjusting the air pressure to
the pump. Locate the regulator close to the pump,
but upstream from the bleed-type master air valve.
The fluid drain valve (B) is required in your sys -
tem to relieve fluid pressure in the pump, hose and
gun (see the WARNING above).
Air Line Accessories
Install the following accessories in the order shown in
the T ypical Installation, using adapters as necessary:
 A pump runaway valve (S) senses when the
pump is running too fast and automatically shuts of f
the air to the motor . A pump which runs too fast can
be seriously damaged.
An air line lubricator (M) provides automatic air
motor lubrication.
An air line filter (L) removes harmful dirt and
moisture from the compressed air supply .
A second
bleed-type air valve (H) isolates the air
line accessories for servicing. Locate upstream
from all other air line accessories.
Air and Fluid Hoses
Connect a grounded fluid hose (P) to the 3/8 npsm(f)
outlet union (E) of the surge tank outlet manifold (C).

For T
wo Gun Systems
Each line in a two gun system must have a shutof f
valve to relieve fluid pressure if the fluid line becomes
clogged, and to isolate one gun for servicing while the
other is in operation. Director valve 214–71 1 is recom -
mended for both purposes. Use elbow 100–840 to di -
rect the outlet flow from the drain valve in a safe direc -
tion to a waste container . Use reducer bushings
100–176 and 100–206 to connect the valve to the out
-
lets of surge tank 214–624.
In the draining mode, the valve handle is turned away
from the elbow (marked DRAIN on the valve housing);
in the operating mode, the handle is turned toward the
elbow (marked CIRC on the housing).
