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 rupture and result in fluid injection, splashing in eyes or on
skin,
or
other serious injury
, or fire, explosion or property dam
-
age.
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
.
Noise
Ear
protection is recommended when the sprayer is operating.
Refer
to the Sound Level in the
T
echnical Data
on page 43.
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 must be chemically compat
-
ible
with the wetted parts shown in the
T
echnical Data
on page
43.
Consult your chemical supplier to ensure compatibility
.
Do
not use 1,1,1-trichloroethane, methylene chloride, other ha
-
logenated hydrocarbon solvents or fluids containing such sol-
vents in this equipment, which contains aluminum and/or zinc
parts.
Such
use could result in a serious chemical reaction, with
the
possibility of explosion, which could cause death, serious in
-
jury
and/or substantial property damage.
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
injury or property
damage.
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 en
-
tire
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 it immediately. An un-
grounded
or poorly grounded hose can make
your system haz
-
ardous.

FLUID
INJECTION 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 serious injury and property damage.
If you experience any static sparking or even a slight shock
while
using
this equipment, ST
OP SPRA
YING IMMEDIA
TELY.
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 instruc
-
tions
for your area and type of equipment. BE SURE to ground
all
of this spray equipment:
1.
Sprayer:
connect a ground wire and clamp (supplied) to a
true
earth ground.
2.
Fluid hoses:
use only grounded hoses with a maximumf
500 ft (150 m) combined hose length to ensure grounding
continuity.
See
Hose Grounding Continuity
,
above.
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 15
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.
GASOLINE
ENGINE HAZARD
NEVER
fill the fuel tank while the engine is running or hot. Fuel
spilled
on a hot surface can ignite and cause a fire.
ALWAYS
pour fuel in slowly
to avoid spilling. Also read
Fire Or
Explosion Hazard
, above, and
Fueling
on page 1
1.
NEVER
operate the engine in a closed building unless the en
-
gine exhaust is piped outside. The exhaust contains carbon
monoxide, a poisonous, odorless and invisible gas which can
cause
serious illness and even death of inhaled.
IMPORTANT
United
States Government safety standards have been adopted under the Occupational Safety and Health Act.
These standards – particularly the
General Standards, Part 1910, and the Construction Standards, Part 1926 – should be consulted.
