Graco PRO AA5500SC Instructions And Parts List page 5

General Safety
Any misuse of the spray equipment or accessories, such as
over pressurizing, modifying parts, using improper replace-
ment parts, using incompatible chemicals and fluids, or using
worn or damaged parts, can cause them to rupture and result
in serious injury, including fluid injection and splashing fluid in
the eyes or on the skin, or in fire, explosion or property dam-
age.
Only use genuine Graco replacement parts when servicing
the gun. Do not mix or use other PRO Gun parts that may
look similar, but have different part numbers!
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.
Read and follow the fluid and solvent manufacturer's litera-
ture regarding the use of protective clothing and equipment,
such as eye protection, respiratory protection, and gloves.
Provide proper ventilation in accordance with accepted
industry standards and governmental regulations. Refer to
Ventilate the Spray Booth, on page 10.
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 coming from it
can cause a fluid injection injury or other serious injury or
property damage.
All fluid spray hoses must have a spring guard 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 come out of the coupling.
Never use a damaged hose. Before each use, check the
entire hose for cuts, leaks, abrasion, bulging cover, or dam-
age or movement of the hose couplings. If any of these con-
ditions 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.
United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards––particularly the Gen-
eral Standards, Part 1910.107 and any other appropriate regulations––should be consulted in connection with the installation, operation, and mainte-
nance of electrostatic spray painting equipment.
EQUIPMENT MISUSE HAZARD
HOSE SAFETY
IMPORTANT
System Pressure
The PRO AA5500SC electrostatic spray gun has a 3000 psi
(207 bar) Maximum Working Fluid Pressure and 100 psi (7
bar) Maximum Working Air Pressure . Never exceed these
pressures!
The high pressure fluid supply pump must be limited so that it
is not capable of producing a fluid pressure greater than the
maximum working fluid pressure of the spray gun or any
other system component.
Be sure that all spray equipment and accessories added to
the spray system are properly rated to withstand maximum
working pressure of your system. Do not exceed maximum
working pressure of any component or accessory used in the
system.
Fluid Compatibility
Be sure all fluids and solvents used are chemically compat-
ible with the "Wetted Parts" shown in the Technical Data, on
the back page. Always read and follow the fluid and solvent
manufacturer's literature before using the fluid or solvent in
this gun.
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 Graco hose to temperatures above 180
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 fluid
hose does not have a tag on it which specifies the maximum
electrical resistance, contact the hose supplier or manufac-
turer 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 lim-
its, replace it immediately. An ungrounded or poorly grounded
hose can make your system hazardous. Also read FIRE, EX-
PLOSION, OR ELECTROSTATIC SHOCK HAZARD on
