EQUIPMENT MISUSE HAZARD
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, 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 respirator as
recommended by the fluid and solvent manufacturer.
System Pressure
The maximum working pressure of this displacement pump is 3000 psi
(210 bar). The working pressure is determined by the air or hydraulic
motor. Do not exceed the maximum working pressure stated on your
complete pump, or 3000 psi (210 bar), whichever is smaller.
Be sure that all spray equipment and accessories are rated to with-
stand the maximum working pressure of the pump. Do not exceed the
maximum working pressure of any component or accessory used in
the system.
Fluid Compatibility
Be sure that all fluids and solvents used are chemically compatible
with the wetted parts shown in the
Technical Data on the back cover.
Always read the manufacturer’s literature before using fluid or solvent
in this pump.
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 in-
jection 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 entire hose
for cuts, leaks, abrasion, bulging cover, or damage or movement of the
hose couplings. If any of these conditions exist, replace the hose im-
mediately. Do not try to recouple high pressure hose or mend it with
tape or any other device. A repaired hose cannot safely contain the
high pressure fluid.
Handle and route hoses carefully. Do not pull on hoses to move
equipment. Do not use fluids which are not compatible with the inner
tube and cover of the hose. Do not expose Graco hoses to tempera-
tures 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 air
and 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,
below.
FIRE OR EXPLOSION HAZARD
Static electricity is created by the high velocity 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 hazard-
ous. 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 explosion
and serious bodily injury and property damage. Do not plug in or un-
plug 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 corrected.
Grounding
To reduce the risk of static sparking, ground the pump 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.
Pump: use a ground wire and clamp as shown in your separate
pump manual.
2.
Air or hydraulic hoses: use only grounded hoses.
3.
Fluid hoses: use only grounded fluid hoses.
4.
Air compressor or hydraulic supply: follow manufacturer’s recom-
mendations.
5.
Spray gun: grounding is obtained through connection to a properly
grounded fluid hose and pump.
6.
Fluid supply container: according to local code.
7.
Object being sprayed: according to your local code.
8.
All solvent pails used when flushing, according to local code. Use
only metal pails, which are conductive, placed on a grounded
surface. Do not place the pail on a nonconductive surface, such
as paper or cardboard, which interrupts the grounding continuity.
9.
To maintain grounding continuity when flushing or relieving pres-
sure, always hold a metal part of the spray gun firmly to the side of
a grounded
metal pail, then trigger the spray gun.
Flushing Safety
Before flushing, be sure the entire system and flushing pails are prop-
erly grounded. Refer to
Grounding, at the left. Follow the Pressure
Relief Procedure on page 2, and remove the spray tip from the
spray gun. Always use the lowest possible fluid pressure, and main-
tain firm metal-to-metal contact between the spray gun and the pail
during flushing to reduce the risk of fluid injection injury, static sparking
and splashing.
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.
