EQUIPMENT MISUSE HAZARD
General
Safety
Misuse
of the equipment or accessories, such as overpressuri
-
zing,
modifying parts, using incompatible chemicals and fluids,
or
worn or damaged parts,
can cause them to rupture and result
in
fluid injection, splashing on the eyes or skin,
or other serious
bodily
injury
, or 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 ear protection, protective
eyewear
, gloves, cloth
-
ing and respirator as recommended by the fluid and solvent
manufacturer.
System
Pressure
This sprayer can develop
3000 psi (195 bar) MAXIMUM
WORKING
PRESSURE
.
Be sure that all
spray equipment and
accessories
used are rated to withstand this pressure. DO NOT
exceed
the maximum working pressure of any part used in the
system.
Fluid and Solvent Compatibility
BE
SURE that all
fluids and solvents used are chemically com
-
patible
with the wetted parts shown in the
TECHNICAL DATA
on page 20. Always read the fluid and solvent manufacturer ’s
literature
before using them in this sprayer
.
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 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 both ends!
The
spring guards 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 hose 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.

FIRE OR EXPLOSION HAZARD.
FIRE OR EXPLOSION HAZARD
Static
electricity is created by the flow of fluid through the pump
and hose. If all spray equipment is not properly grounded,
sparking may occur and the system may become hazardous.
Sparking
may also occur when plugging or unplugging a power
cord. Sparks can ignite fumes from solvents, the fluid being
sprayed, dust particles and other flammable substances,
whether
spraying indoors 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,
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 the ground wire and clamp (provided) to
a
true earth ground. See Fig 1.
Fig
1
CLAMP
2.
Fluid hoses:
use only grounded hoses with a maximum of
150
m combined hose length to ensure grounding continu
-
ity.
See
Hose Grounding Continuity.
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
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 6 of this
manual.
GASOLINE ENGINE HAZARDS
NEVER
fill the fuel tank while the engine is running or hot. Fuel
spilled on a hot surface can ignite and cause a fire. AL WAYS
pour
fuel in slowly to avoid spilling.
NEVER operate the engine in a closed building unless the
engine
exhaust is piped outside. The exhaust contains carbon
monoxide, a poisonous, odorless and invisible gas which can
cause
serious illness and even death if inhaled.
NEVER alter the throttle setting which is factory set at the
maximum
full load engine speed of 2800 RPM. T
ampering with
this
can change the sprayer and will void the warranty
.
IMPORTANT
United States Government safety standards have been
adopted
under the Occupational Safety and Health Act. These
standards – particularly the General Standards, Part 1920 and
the
Construction Standards, Part
1926 – should be consulted.
