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 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 respirator
as
recommended by the fluid and solvent manufacturer
.
System
Pressure
This
sprayer can develop 3000 psi (210 bar)
MAXIMUM WORK
-
ING
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 compatible
with
the wetted parts
shown in the
TECHNICAL DA
TA
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
injection
injury
or other serious bodily injury or property damage.
ALL
FLUID HOSES MUST HA
VE 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 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. 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 tempera-
tures
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, con
-
tact the hose supplier or manufacturer for the maximum resis-
tance
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 ungrounded or
poorly
grounded hose can make your system hazardous.
Always
read the chemical manufacturer
’
s literature before
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 haz
-
ardous.
Sparking may also occur when plugging in or
unplugging
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
in
-
doors
or outdoors, and can cause a
fire or explosion and serious
bodily
injury and property damage.
If
you experience any static sparking or even a slight shock while
using
this equipment,
STOP
SPRA
YING IMMEDIA
TELY
. Do not
use
the system until the problem is 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.
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 maximum
f 500
ft (150 m) combined hose length to ensure grounding continu
-
ity.
See
Hose Grounding Continuity above.
3.
Spray
gun:
obtain grounding through connection to a properly
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 splash
-
ing
by following the flushing procedure on page 12.
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
.
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.
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.
