EQUIPMENT MISUSE HAZARD
General S a f e t y
Any misuse of the spray equipment or accessories, such as
overpressurizing,
modifying parts, using incompatible
chemicals and fluids, or using worn or damaged parts, can
cause them to rupture and result in fluid injection or other
serious bodily injury, fire, explosion or property damage.
NEVER alter or modify any part of this equipment; doing so
could cause
to malfunction.
it
CHECK all spray equipment regularly and repair or replace
worn or damaged parts immediately.
Read and follow the fluid and solvent manufacturer's literature
regarding the use of protective clothing and equipment.
S y s t e m Pressure
This sprayer can develop 192 bar (2750 psi) MAXIMUM
WORKING PRESSURE. Be sure that all spray equipment and
accessories are rated to withstand the maximum working
pressure of this sprayer. DO NOT exceed the maximum work-
ing pressure of any component or accessory used in the
system.
F l u i d C o m p a t i b i l i t y
BE SURE that a 1 1 fluids and solvents used are chemically com-
patible with the wetted parts shown in the Technical Data on
the back cover. Always read the fluid and solvent manufac-
turer's literature before using them in this sprayer.
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 ENDS1 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
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
repaired hose cannot contain the high pressure fluid.
HANDLE AND ROUTE HOSES CAREFULLY. Do
hoses to move equipment. Do not use fluids or solvents which
are not comoatible with the inner tube and cover of the hose.
DO NOT expose Graco hose to temperatures above
1180°F) or below -4OOC (-4OOF).
Grounding Continuity
H o s e
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
which specifies the maximum electrical
it
resistance, contact the hose supplier ormanufacturer for the
maximum resistance limits. Use a resistance meter in the ap-
propriate range for your hose to check the resistance. If the
resistance exceeds the recommended limits, replace
mediately. An ungrounded or poorly grounded hose can make
your system hazardous. Also read FIRE OR EXPLOSION
HAZARD.
United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards-par-
ticularly the General Standards, Part 1910, and the Construction Standards, Pan 1926-should be consulted.

IMPORTANT
FIRE OR EXPLOSION HAZARD
Static electricity is created by the flow of fluid through the
pump and hose. If every pan 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 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 6 m
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 IMMEDI-
ATELY. Check the entire system for proper grounding. Do not
use the system again until the problem has been identified and
corrected.
G r o u n d i n g
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 in-
structions 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 properly grounded outlet. Do not use an adapter. All ex-
tension cords must have three wires and be rated for 15
amps.
2.
Fluid hoses: use only grounded hoses with a maximum of
500
feet 1150 m) combined hose length to ensure ground-
ing continuity. Refer to Hose Grounding Continuity.
3.
Spray gun: obtain grounding through connection to a
properly grounded fluid hose and sprayer.
Fluid supply container: according to local code.
4.
5.
Object being Sprayed: according to local code.
6.
All solvent pails used when flushing, according to local
code. Use only metalpails, which are conductive. Do not
place the pail on a non-conductive surface, such aspaper
or cardboard, which interrupts the grounding continuity.
7.
To maintain grounding continuity when flushing orreliev-
ingpressure, always hold
the side of a grounded metal pail, then trigger the gun.

Flushing S a f e t y
Reduce the risk of fluid injection injury, static sparking, or
splashing by following the specific flushing procedure given

cedure on page 2, and remove the spray
Hold a metal part of the gun firmly to the side of a 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. Unplug the sprayer, and follow the
Pressure Relief Procedure on page 2 to prevent
ting accidentally.
