EQUIPMENT MISUSE HAZARD
General Safety
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 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.
Always wear protective eyewear, gloves, clothing and respira-
tor as recommended by the fluid and solvent manufacturer.
Wear ear–noise protection when working near the sprayer
when the engine is operating.
System Pressure
This sprayer can develop 3000 psi (210 bar)
MAXIMUM
WORKING PRESSURE. Be sure all spray equipment and ac-
cessories 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 compat-
ible with the wetted parts shown in the TECHNICAL DATA on
page 39. 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.
HOSE SAFETY
High pressure fluid in the hoses can be dangerous. If the hose
develops a leak, split or rupture due to wear, damage or misuse,
the high pressure spray emitted from it can cause a fluid injec-
tion 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 hose
for cuts, leaks, abrasion, bulging cover, or damage or move-
ment of the hose couplings. If any of these conditions exist, re-
place 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 carefully. Do not pull on hoses to
move equipment. Keep hoses clear of moving parts and hot sur-
faces 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 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.
Always read the chemical manufacturer’s literature before us-
ing them in this sprayer.
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 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.
If you experience any static sparking or even a slight shock
while using this equipment, STOP SPRAYING IMMEDIATELY.
Do not use the system until the problem is 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 instruc-
tions for your area and type of equipment. BE SURE to ground
all of this spray equipment:
1.
Sprayer: connect a ground wire and clamp (supplied) to a
true earth ground.
2.
Fluid hoses: use only grounded hoses with a maximum
f
500 ft (150 m) combined hose length to ensure grounding
continuity. See Hose Grounding Continuity above.
3.
Spray gun: obtain grounding through connection to a prop-
erly grounded fluid hose and sprayer.
4.
Object being sprayed: follow local code.
5.
Fluid supply container: follow local code.
6.
All solvent pails used when flushing, follow local code. Use
only metal pails, which are conductive. Do not place the pail
on a non–conductive surface, such as paper or cardboard,
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
splashing by following the flushing procedure on page 12.
GASOLINE ENGINE HAZARD
NEVER fill the fuel tank while the engine is running or hot. Fuel
spilled on a hot surface can ignite and cause a fire.
ALWAYS pour fuel in slowly to avoid spilling. Also read FIRE OR
EXPLOSION HAZARD, above, and FUELING on page 9.
NEVER operate the engine in a closed building unless the en-
gine exhaust is piped outside. The exhaust contains carbon
monoxide, a poisonous, odorless and invisible gas which can
cause serious illness and even death of inhaled.
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.
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.
