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.
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 skin 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 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.
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
damage.
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 instructions 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.
Fluid hoses: use only grounded hoses with a maximum of
2.
500 ft (150 meter) combined hose length to ensure ground-
ing continuity. See Hose Grounding Continuity.
3. Spray gun: obtain grounding through connection to a prop-
erly grounded fluid hose and sprayer.
4. Object being sprayed: according to local code.
EQUIPMENT MISUSE HAZARD
HOSE SAFETY
FIRE OR EXPLOSION HAZARD
System Pressure
This sprayer can develop 3000 psi (210 bar) Maximum Working
Pressure . Be sure that all spray equipment and accessories
used are rated to withstand 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
44. 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.
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 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 hose to temperatures above 180 F (82
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.
Fluid supply container: according to local code.
5.
All solvent pails used when flushing, according to local
6.
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.
To maintain grounding continuity when flushing or relieving
7.
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 skin injection injury, static sparking, or
splashing by following the flushing procedure given on page 15
of this manual. Follow the Pressure Relief Procedure on page
4, 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.
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 4
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.
