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
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 respira-
tor as recommended by the fluid and solvent manufacturer.
Wear hearing protection when operating this equipment.
System Pressure
Do not exceed 5000 psi (345 bar)Maximum Working Pressure
to the gun.Be sure all spray equipment and accessories used
are rated to withstand this pressure. Do not exceed the maxi-
mum working pressure of any component or accessory used in
the system.
Fluid and Solvent Compatibility
All chemicals used in the sprayer must be chemically compat-
ible with the wetted parts shown in the TECHNICAL DATA on
the back cover. Consult your chemical supplier to ensure
compatibility.
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 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 ex-
ist, replace the hose immediately. Do not try to recouple high
pressure hose or mend it with tape or any other device. A re-
paired hose cannot contain the high pressure fluid.
Handle and route hoses carefully. Do not pull on hoses to move
equipment. Keep hoses clear of moving parts and hot surfaces
of the pump and power supply. 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
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 re-
sistance 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 un-
grounded or poorly grounded hose can make your system haz-
ardous. Also read FIRE OR EXPLOSION HAZARD, below.
FIRE OR EXPLOSION HAZ-
ARD
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 un-
plugging 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 indoors or outdoors, and can cause
a fire or explosion and serious bodily injury and property dam-
age. 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
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 instructions for
your area and type of equipment. Be sure to ground all of this
spray equipment:
.Pump or Sprayer: provide appropriate grounding as recom-
mended in your pump or sprayer instruction manual.
.Fluid hoses: use only grounded hoses with a maximum of
500 ft (150 m) combined hose length to ensure grounding
continuity. See Hose Grounding Continuity, above.
.Spray gun: obtain grounding through connection to a prop-
erly grounded fluid hose and sprayer.
.Object being sprayed: according to local code.
.Fluid supply container: according to local code.
.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.
.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
To reduce the risk of fluid injection injury, static sparking, or
splashing, be sure the system is properly grounded, relieve
pressure, remove spray tip. 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.

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.
