EQUIPMENT MISUSE HAZARD
General
Safety
Any
misuse of
the spray/dispensing equipment or accessories, such as
overpressurizing,
modifying parts, using incompatible chemicals and flu
-
ids, 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 bod
-
ily
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/dispensing equipment
regularly and repair or replace
worn
or damaged parts immediately
.
Always
wear protective eyewear
, gloves, clothing and
respirator as rec
-
ommended
by the fluid and solvent manufacturer
.
System
Pressure
NEVER
exceed the recommended working pressure or the maximum air
inlet pressure stated on your pump or in the TECHNICAL DATA on
pages
24-29.
Be
sure that all
spray/dispensing equipment and accessories are rated to
withstand
the maximum working pressure of the pump. DO NOT
exceed
the
maximum
working pressure of any component or accessory used in
the
system.
Fluid
Compatibility
BE
SURE that all fluids and solvents used are chemically compatible with
the
wetted parts shown in the
TECHNICAL DA
TA
on pages 24-29. Al
-
ways
read the manufacturer
s literature before using fluid or solvent
in
this
pump.
HOSE SAFETY
High
pressure fluid
in the hoses can be very dangerous. If the hose devel
-
ops
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 HA VE 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 pressure spray to be
emitted
from the coupling.
NEVER
use a damaged hose. Before each use, check the entire 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 safely contain the high pressure
fluid.
HANDLE
AND ROUTE HOSES CAREFULL
Y
. Do not pull on hoses to
move
equipment. Do not use fluids which are not compatible
with the in
-
ner
tube and cover of the hose. DO NOT expose Graco hoses to tem
-
peratures
above 82
_
C (180
_
F) or below –40
_
C (–40
_F).
Hose Grounding Continuity
Proper
hose grounding continuity is essential to maintaining a grounded
spray/dispensing
system. Check the electrical resistance of your air and
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 sup
-
plier or manufacturer for the maximum resistance 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 hazard
-
ous.
Also, read
FIRE OR EXPLOSION HAZARD
, below
.
FIRE OR EXPLOSION HAZARD
Static
electricity is created by the high velocity flow of fluid through the
pump and hose. If every part of the spray/dispensing equipment is not
properly
grounded, sparking may occur
, and the system may become
hazardous.
Sparking may also occur when plugging in or unplugging a
power
supply cord. Sparks can ignite fumes from solvents and the fluid
being sprayed/dispensed, dust particles and other flammable sub-
stances,
whether
you are spraying/dispensing indoors or outdoors, and
can
cause a fire or explosion
and serious bodily injury and property dam
-
age.
Do not plug in or unplug any power supply cords in the spray/dis
-
pensing area when there is any chance of igniting fumes still
in the air
.
If
you experience any static sparking or even a slight shock while using
this equipment, STOP SPRA YING/DISPENSING IMMEDIATELY.
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 pump, object being
sprayed,
and all other spray/dispensing equipment used or located in the
spray/dispensing area. CHECK your local electrical code for detailed
grounding
instructions for your area and type of equipment. BE SURE to
ground
all of this spray/dispensing equipment:
1.
Pump:
use a ground wire and clamp. See Fig 1.
2.
Air hoses:
use only grounded air hoses.
3.
Fluid hoses:
use only grounded fluid hoses.
4.
Air compressor:
follow manufacturer
s recommendations.
5.
Spray
gun or dispensing valve:
grounding is obtained through con
-
nection
to a properly grounded fluid hose and pump.
6.
Fluid supply container:
according to your local code.
7.
Object being sprayed:
according to your local code.
8.
All
solvent pails used when flushing,
according to your local
code.
Use only metal pails, which are conductive, placed on a grounded
surface.
Do not place the pail on a nonconductive
surface, such as
paper
or cardboard, which interrupts the grounding continuity
.
9.
T
o maintain grounding continuity when flushing
or relieving pres
-
sure
, always
hold a metal part of the spray gun/dispensing valve
firmly
to the side of a grounded
metal
pail, then trigger the gun/valve.
To ground the pump:
To ground the pump, loosen the grounding lug locknut (W) and
washer
(X). Insert one end of a 1.5 mm
@
(12 ga) minimum ground
wire
(Y) into the slot in lug (Z) and tighten the locknut securely
. See
Fig 1. Connect the other end of the wire to a true earth ground. See
the
ACCESSORIES section to order a ground wire and clamp.

Flushing Safety
Before
flushing, be sure the
entire system and flushing pails are properly
grounded. Refer to Grounding, above. Follow the Pressure Relief
Procedure
on page 2, and remove the spray tip/nozzle from the spray
gun/dispensing
valve. Always use the
lowest possible fluid pressure, and
maintain
firm metal-to-metal contact between the gun/valve and the pail
during
flushing to reduce the risk of fluid injection injury
, static sparking
and
splashing.
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.
