EQUIPMENT MISUSE HAZARD
General
Safety
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 the eyes
or
on the skin, or
other serious injury
, fire, explosion 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.
Wear ear–noise protection when working near the sprayer
when
the engine is operating.
System
Pressure
This sprayer can develop 3000 psi (210 bar)
MAXIMUM
WORKING PRESSURE.
Be sure all spray equipment and ac
-
cessories 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
TECHNICAL DATA
on
page
39. 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
bodily
injury and/or substantial property damage.
HOSE SAFETY
High
pressure fluid in the hoses can be dangerous.
If the hose
develops
a leak, split or rupture due to wear
, damage or misuse,
the
high pressure spray emitted from it can cause
a fluid injec
-
tion
injury or other serious bodily 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 hose
for cuts, leaks, abrasion, bulging cover, or damage or move-
ment
of the hose couplings. If any of these conditions exist, re
-
place
the hose immediately
. DO NOT try to recouple high pres
-
sure
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. Keep hoses clear of moving parts and hot sur
-
faces
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.
Always
read the chemical manufacturer
’
s literature before us
-
ing 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 serious bodily injury and property dam
-
age.
If you experience any static sparking or even a slight shock
while
using this equipment,
ST
OP SPRA
YING IMMEDIA
TELY.
Do not use the system until the problem is 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:
follow local code.
5.
Fluid supply container:
follow local code.
6.
All solvent pails used when flushing,
follow local code. Use
only
metal pails, which are conductive. Do not place the pail
on a non–conductive surface, such as paper or cardboard,
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 on page 12.
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 9.
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.
MOVING
P
ARTS HAZARD
Moving
parts
can pinch or amputate your fingers or other body
parts.
KEEP CLEAR of moving parts when starting or
operating
the
sprayer
. Follow the
Pressure Relief Procedure
on page
2
before checking
or servicing any part of the sprayer
, to prevent
it
from starting accidentally
.
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.
