EQUIPMENT MISUSE HAZARD
General Safety
Any misuse of the spray equipment or accessories, such as
overpressurizing. modifying parts, using incompatible chemi-
cals and fluids, or using worn or damaged parts, can cause
them to ruoture and result in fluid iniection. solashino in the eves
or on the skin, or other serious bodily inju&,'orfire. Explosioi 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 respira-
tor as recommended by the fluid and solvent manufacturer.
System Pressure
This sprayer can develop 3000 psi (210 bar) MAXIMUM
WORKING PRESSURE. Be sure that all spray equipment and
accessories used are rated to withstand this pressure.
DO
NOT
exceed the maximum working pressure of any component or
accessory used in the system.
Fluid and Solvent Compatibility
BE SURE that all fluids and solvents used are chemically com-
patible with the wetted parts shown in iheTECHNlCAL DATA
on page 35. Always read the fluid and solvent manufacturer's
literature before using them in this sprayer.
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous.

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 pres-

NEVER use a damaged hose. Before each use, check the en-
movement of the hose couplings. I f any of these conditions ex-
ist, replace the hose immediately. DO NOT try to recouple high
pressure hose or mend it with tape or any other device. A re-
paired 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 gas engine. Do not use fluids
or solvents which are not compatible with the inner tube and
coverofthe hose. DO NOTexpose Graco hose to temperatures
above 180'
F ( 8 2 ' ' C) or below -40° F (40' C).
Hose Grounding Continuity

Proper hose grounding continuity is essential to maintaining a
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 re-
sistance limits. Use a resistance meter in the appropriate range
for your hose to check the resistance. lfthe resistance exceeds
the recommended limits, replace it immediately. An un-
grounded or poorly grounded hose can make your system haz-
ardous. Also read FIRE OR EXPLOSION HAZARD.
