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 above
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 3000 psi (210 bar)
Maximum Working
Pressure.
Be sure all spray equipment and accessories used
are rated to withstand this pressure. Do not exceed the maxi-
mum working pressure
of any component 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 44. 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 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.

FIRE OR EXPLOSION HAZARD, below.
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 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
with a gasoline
engine:
use the ground wire to connect
to
a true earth ground according to local code.
Sprayer with electric motor:
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 continuity
.
See Hose Grounding Continuity, above.
3.
Spray
gun:
obtain grounding through connection to a properly
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 pres
-
sure
,
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 14
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 Gen
-
eral
Standards, Part 1910, and the Construction Standards, Part 1926 - should be consulted.
