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, 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 2750 psi

bar/ MAXIMUM
accessories are rated to withstand the maximum working
WORKING PRESSURE. Be sure that all spray equipment and
pressure of this sprayer. DO NOT exceed the maximum work-
ing pressure of any component or accessory used in the
system.
Always reed the fluid and .solvent. manufacturer's literature
Fluid and Solvent Compatibility
before using them in this sprayer.
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
propeny darnage.
ALL FLUID HOSES MUST HAVE SPRING GUARDS ON
BOTH ENDS The spring guards help protect the hose from
kinks or bends
a t
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.

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. U s e 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
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 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 in-
doors or outdoors, and can cause a fire or explosion and
serious bodily injury and property damage. Always plug the
sprayer into an outlet a t least
20
feet 1 6 m) awav from the
spraver and the spray area. Do not plug i n or
d in plug
any
power supply cords in the spray area when there is any chance
of igniting fumes still in the air.

Sprayer: plug the power supply cord, or extension cord,
a properly grounded outlet.
Do
not use an adapter. All ex-
each equipped with an undamaged three-prong plug, into
tension cords must have three wires and be rated for 15
amps.
Fluid hoses: use only grounded hoses with a maximum of
500 feet (150 m l combined hose length to ensure ground-
ing continuity. Refer to Hose Groundlng Contlnulty.
Spray gun: obtain grounding through connection to a
properly grounded fluid how 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 metalpails, which are conductive. Do not
place the pail on a non-conductive surface, such as paper
or cardboard, which interrupts the grounding continuity.

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 2, 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 HAZARD
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.
