EQUIPMENT MISUSE HAZARD
General
Safety
Misuse of the spray equipment or accessories, such as over
pressurizing, 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 the
skin,
or other injury, or fire, explosion or property damage.
Never
alter or modify any part of this equipment; doing so
could
cause
the equipment 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 all spray equipment and accessories used
are rated to withstand the this pressure. Do not exceed the
maximum working pressure of any component or accessory
used
in the system.
Fluid and Solvent Compatibility
All chemicals used in the sprayer are chemically compatible
with
the wetted parts shown in the
T
echnical Data
on the back
cover. Always read the chemical manufacturer’s literature be-
fore
using them in this sprayer
.
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 un-
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 injury and property damage.
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 cor-
rected.
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:
1.
Sprayer:
plug
the power supply
cord, or extension cord, each
equipped
with an undamaged three-prong plug, into a prop
-
erly grounded outlet. Do not use an adapter. All extensions
cords
must have three wires and be rated for 15 amps.
2.
Fluid hoses:
use only grounded hoses with a maximumof
500 ft (150 m) combined hose length to ensure grounding
continuity.
See
Hose Grounding Continuity below.
3.
Spray gun:
obtain grounding through connection to a prop-
erly
grounded fluid hose and sprayer
.
4.
Object being sprayed:
according to local code.
5.
Fluid supply container:
according to local code.
6.
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 card-
board,
which interrupts the grounding continuity
.
7.
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
Reduce the risk of fluid injection injury, static sparking, or
splashing
by following the flushing procedure given on page 13
of
this manual. Follow the
Pressure Relief Procedure
on page
4, and remove the spray tip before flushing. 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.
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 a hose
can
cause a fluid injection injury or other injury or property dam
-
age.
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 pres
-
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 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 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 re
-
sistance
limits. Use a resistance meter in the appropriate range
for your hose to check the resistance. If the resistance exceeds
the
recommended limits, replace the hose
immediately
. An un
-
grounded
or poorly grounded hose can make
your system haz
-
ardous.
