MOVING PARTS HAZARD
Moving parts can pinch or amputate your fingers or other body
parts. KEEP CLEAR of moving parts when starting or operating
the sprayer. Follow the Pressure Relief Procedure on page 2
before checking or servicing any part of the sprayer, to prevent
it from starting accidentally.
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, explosion or prop-
erty 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 respirator
as recommended by the fluid and solvent manufacturer.
System Pressure
This sprayer can develop 2750 psi (190 bar) MAXIMUM WORK -
ING PRESSURE. Be sure all spray equipment and accessories
used are rated to withstand the this pressure. DO NOT exceed
the maximum working pressure of any component or accessory
used in the system.
Fluid and Solvent Compatibility
All chemicals used in the sprayer must be chemically compatible
with the wetted parts shown in the TECHNICAL DATA on page
31. Consult your chemical supplier to ensure compatibility.
Do not use 1,1,1-trichloroethane, methylene chloride, other ha-
logenated hydrocarbon solvents or fluids containing such sol-
vents in this equipment, which contains aluminum and/or zinc
parts. Such use could result in a serious chemical reaction, with
the possibility of explosion, which could cause death, serious
bodily injury and/or substantial property damage.
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 haz-
ardous. Sparking may also occur when plugging in or unplugging
a power supply cord or using a gasoline engine. Sparks can ignite
fumes from solvents and the fluid being sprayed, dust particles
and other flammable substances, whether you are spraying in-
doors or outdoors, and can cause a fire or explosion and serious
bodily injury and property damage. Always plug the sprayer into
an outlet at least 20 feet (6 m) away from the sprayer and the spray
area. 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 corrected.
Grounding
To reduce the risk of static sparking, ground the sprayer and all
other spray equipment used or located in the spray area.
CHECK your local electrical code for detailed grounding instruc-
tions for your area and type of equipment. BE SURE to ground
all of this spray equipment:
1. Sprayer: plug the power supply cord, or extension cord – each
equipped with an undamaged, three–prong plug, into a prop-
erly grounded outlet. Do not use an adapter . All extension
cords must have three wires and be rated for 15 Amps.
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 Con-
struction Standards, Part 1926 – should be consulted.
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 prop-
erty damage.
ALL FLUID HOSES MUST HAVE STRAIN RELIEFS ON BOTH
ENDS! The strain reliefs 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 pres-
sure 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 pres-
sure hose or mend it with tape or any other device. A repaired
hose cannot contain the high pressure fluid.
HANDLE AND ROUTE HOSES CAREFULL Y. Do not pull on
hoses to move equipment. Keep hoses clear of moving parts
and hot surfaces of the pump and gas engine. 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 tempera-
tures 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
fluid hoses at least once a week. If your hose does not have a
tag on it which specifies the maximum electrical resistance, con-
tact the hose supplier or manufacturer for the maximum resis-
tance 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 EXPLOSION HAZARD, below.
2. Fluid hoses: use only grounded hoses with a maximum f 500
ft (150 m) combined hose length to ensure grounding continu-
ity. See Hose Grounding Continuity on page 3.
3. Spray gun: obtain grounding through connection to a properly
grounded fluid hose and sprayer.
4. Object being sprayed: according to local code.
5. Fluid supply container: according to local code.
6. All solvent pails used when flushing, according to local code.
Use only metal pails, which are conductive. Do not place the
pail on a non–conductive surface, such as paper or card-
board, which interrupts the grounding continuity.
7. To maintain grounding continuity when flushing or relieving
pressure , always hold a metal part of the gun firmly to the side
of a grounded metal pail, then trigger the gun.
Flushing Safety
Reduce the risk of fluid injection injury, static sparking, or splash-
ing by following the flushing procedure given on page 12 of this
manual. Follow the PRESSURE RELIEF PROCEDURE on
page 2, and remove the spray tip before flushing. Hold a metal
part of the gun firmly to the side of a grounded metal pail and use
the lowest possible fluid pressure during flushing.
