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
.
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 the eyes
or
on the 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 protective eyewear
, gloves, clothing and respira
-
tor
as recommended by the fluid and solvent manufacturer
.
System Pressure
This sprayer can develop
2750 psi (190 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 component or
accessory
used in the system.
Fluid and Solvent Compatibility
All
chemicals used in the sprayer must be compatible with
the
wetted
parts
shown in the
TECHNICAL DA
TA
on page 47. Con
-
sult
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 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 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
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
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 of
500 ft (150 m) combined hose length to
ensure
grounding
continuity.
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 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.
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.
