EQUIPMENT MISUSE HAZARD
General Safety
Any misuse of the spray equipment or accessories, such as
overpressurizing, modifying parts, using incompatible chemiĆ
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 propĆ
erty 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. Wear
hearing protection when operating this equipment.
System Pressure
Do not exceed 5000 psi (345 bar) Maximum Working Pressure
to the gun. Be sure all spray equipment and accessories used
are rated to withstand this pressure. Do not exceed the maxiĆ
mum working pressure of any component or accessory used in
the system.
Fluid and Solvent Compatibility
All chemicals used in the sprayer must be chemically compatible
with the wetted parts shown in the TECHNICAL DATA on the
back cover. Consult your chemical supplier to ensure compatiĆ
bility.
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 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 presĆ
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 exist,
replace the hose immediately. Do not try to recouple high presĆ
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 surfaces
of the pump and power supply. 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 resistance
limits. Use a resistance meter in the appropriate range for your
hose to check the resistance. If the resistance exceeds the recĆ
ommended 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 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 unĆ
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 damĆ
age. 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 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:
. Pump or Sprayer: provide appropriate grounding as recomĆ
mended in your pump or sprayer instruction manual.
. Fluid hoses: use only grounded hoses with a maximum o f
500 ft (150 m) combined hose length to ensure grounding
continuity. See Hose Grounding Continuity, above.
. Spray gun: obtain grounding through connection to a propĆ
erly 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 metal pails, which are conductive. Do not place the
pail on a non-conductive surface, such as paper or cardĆ
board, which interrupts the grounding continuity.
. 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
To reduce the risk of fluid injection injury, static sparking, or
splashing, be sure the system is properly grounded, relieve
pressure, remove spray tip. 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.
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.
