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 or other
serious bodily injury, fire, explosion or property damage.
could cause
it
to malfunction.
NEVER alter or modify any part of this equipment; doing
so
CHECK
all
spray equipment regularly and repair or replace
worn or damaged parts immediately.
Read and follow the fluid and solvent manufacturer's literature
regarding the use of protective clothing and equipment.

PRESSURE.
Be sure that all spray equipment and
accessories are rated to withstand the maximum working
pressure
of
this sprayer. DO NOT exceed the maximum work

ing pressure of any component or accessory used in the
system.
Fluid Compatibility

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 SPRING GUARDS ON

pressure spray to be emitted from the coupling.

NEVER use a damaged hose. Before each use, check the
en-
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

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 ormanufacturer for the
maximum resistance limits. Use a resistance meter in the ap
-
propriate range for your hose to check the resistance. If the
resistance exceeds the
recommended limits, replace
it

FIRE
OR
EXPLOSION HAZARD
Static electricity is created by the flow of fluid through the
pump and hose.
If
every pan 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 at least

feet) away from the
sprayer and the spray area. 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 IMMEDI
-
ATELY. 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.

Sprayer: plug the power supply cord, or extension cord,
each equipped with an undamaged three

All solvent pails used when flushing, according to local
code. Use only metalpails, which are conductive. Do not
place the pail on a non

To
maintain grounding continuity when flushing orreliev-

a
metal part of the gun firmly to
the side of a grounded metal pail, then trigger the gun.
