Static electricity
is created
by the high velocity
flow of fluid
through
the pump and hose. If every part of the spray system
is not properly
grounded,
sparking
may occur, and the system
may become
hazardous.
Sparking
may also occur when plug-
ging in or unplugging
a power supply cord. Sparks can ignite
fumes from
solvents
and the fluid being sprayed,
dust par-
ticles and other flammable
substances,
whether
you are spray-
ing indoors
or outdoors,
and can cause a fire or explosion
and
serious bodily injury and property
damage.
Grounding
To reduce the risk of static sparking,
ground
the pump and all
other components
used or located
in the spray area. CHECK
your local electrical
code for detailed
grounding
instructions
for your area and type of equipment
and be sure to ground
all
of these components:
1.
2.
3.
4.
5.
6.
7.
Pump:
use ground
wire and clamp as shown
in Fig 1.
Air and fluid hoses: use only grounded
hoses with a max-
imum of 500 feet (150 m) combined
hose length
to en-
sure grounding
continuity.
Refer to
Hose Grounding
Continuity.
Air
compressor:
follow
air compressor
manufacturer's
recommendations.
Spray gun or dispensing
valve: obtain grounding
through
connection
to a properly
grounded
fluid hose and pump.
Object being sprayed:
according
to local code.
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.
To maintain
grounding
continuity
when flushing
or reliev-
ing pressure,
always
hold a metal
part of the gun or
dispensing
valve firmly
to the side of a metal pail, then
trigger
the gun or dispensing
valve.
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous.
If the
hose develops
a pinhole
leak, split or rupture
due to any kind
of wear,
damage
or misuse,
the high pressure
spray emitted
from it can cause an injection
injury or other serious bodily in-
jury or property
damage.
ALL FLUID HOSES MUST HAVE SPRING GUARDS!
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 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 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.
Do not use materials
or solvents
which are not compatible
with the inner tube and cover of the
hose. DO NOT expose the hose to temperatures
above 180°F
(82°C) or below
-40°F (-40°C).
To ground
the pump,
loosen the grounding
lug locknut
(A)
and washer
(B). Insert one end of a 12 aa il.5 mm21 minimum
ground
wire
(D)
into the slot in lug (E) and tighten
locknut
securely.
See Fig 1. Connect
the other end of the wire to a
true earthen
ground.
Refer to page 9 to order a ground
wire
and clamp.
Connect
the clamp end of the ground
wire to a
true earthen
ground.
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. Remove
the spray
tip from
the gun (spray guns only).
Always
use the lowest
possible fluid pressure,
and maintain
firm metal to metal con-
tact between
the gun or dispensing
valve and the pail during
flushing
to reduce the risk of injection
injury,
static sparking
and splashing.

Hose
Grounding
Continuity
Grace airless spray hoses have electrically
conductive
material
on the surface
of the center core of the hose. Other hoses on
the market
may have a ground
wire extending
the length
of
the hose. The ground
wire can break in use which will destroy
the electrical
grounding
of the hose.
To be sure of continuity,
check electrical
resistance
at least
once a week.
Check
overall
resistance
when
using multiple
hose
assemblies.
If the
resistance
exceeds
29 megohms,
replace it immediately.
Ground
wire hose may have different
resistance;
check supplier.
MOVING
PARTS HAZARD
Moving
parts
can pinch
or amputate
your fingers
or other
body parts. NEVER operate
the pump with the muffler
plates
removed
to reduce the risk of injuring
your fingers
on moving
parts in the air motor.
KEEP CLEAR
of moving
parts when
starting
or operating
the pump.
Before checking
or servicing
the pump,
follow
the
Pressure Relief Procedure
on page 2
to prevent
the pump
from
starting
accidentally.
ALWAYS
keep hands clear of the intake valve housing while the pump is
operating.
IMPORTANT
United States Government
safety standards
have been adopted
under the Occupational
Safety and Health Act. These standards-par-
ticularly
the General Standards,
Part 1910, and the Construction
Standards,
Part 1926-should
be consulted.
