General Safety
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, splashing in
the eyes or on the skin, or other serious bodily injury, fire, ex-
plosion 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 and clothing as
recommended by the fluid and solvent manufacturer.
System Pressure
This sprayer can develop .5YZ23 psi 1207 bar) 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.
Fluid and Solvent Compatibility
Always read the fluid and solvent manufacturer’s literature
before using them in this sprayer.
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 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
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 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. Do not use fluids or solvents which
are not compatible with the inner tube and cover of the hose.
DO NOT expose Grace hose to temperatures above 1WF
(82°C) or below -40°F (-46°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
resistance 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.
FIRE OR EXPLOSION HAZARD ,.L : ;
Static electricity is created by the high velocity flow of fluid
through the pump and hose. If every part of the spray equip-
ment 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 indoors or outdoors, and can cause a fire or ex-
plosion and serious bodily injury and property damage.
Always plug the sprayer into an outlet at least 26 feet (6 ml
away from the sprayer and the spray erea. 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.
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 in-
structions for your area and type of equipment. BE SURE to
ground all of this spray equipment:
1.
2.
3.
4.
5.
6.
7.
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.
Fluid hoses: use only grounded hoses with a maximum of
560 feet (156 m) combined hose length to ensure ground-
ing continuity. Refer to Hose Grounding Continuity.
Spray gun: obtain grounding through connection to a
properly 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 metaf 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 reliev-
ingpressure, always hold a metal part of the gun firmly to
the side of a grounded metal pai!, then trigger the gun.
Flushing Safety
Reduce the risk of injection injury, static sparking, or splashing
by following the specific flushing procedure given on page 12
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 metal pail and use the
lowest possible fluid pressure during flushing.
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, 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-par-
ticularly the General Standards, Part 1910, and the Construction Standards, Part 1926-should be consulted.
