Static electricity is created by the high velocity flow of fluid
through the pump and hose. If every part of the spray equip-
ment 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,
dust particles and other flammable substances, whether you
are spraying indoors or outdoors, and can cause a fire or ex-
plosion and serious bodily injury and property damage. Do not
plug in or unplug any power supply cords in the spray area
when there is any chance of igniting fumes still in the air.
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 in-
structions for your area and type of equipment. BE SURE to
ground all of this spray equipment:
1.
2 .
3 .
4 .
5 .
6 .
Pump:
use a ground wire and clamp as instructed in your
pump instruction manual.
Fluid hoses:
use only grounded hoses with a maximum
of 500 feet
combined hose length to ensure
grounding continuity. Refer also to Hose Grounding
Continuity.
Spray gun, manifold or dispensing valve:
obtain groun-
ding through connection to a properly grounded fluid
hose and sprayer.
Object being sprayed:
according to local code.
solvent pails
used when flushing, according to local
code.
Use on/y
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 firmly to
the side of a
metal
pail, then trigger the gun.
Flushing Safety
Reduce the risk of injection injury, static sparking, or splashing
by following the specific flushing procedure given on page 5 of
this manual. Follow the Pressure Relief Procedure on page
2, and
remove the spray tip before flushing.
Hold a metal part
of the gun firmly to the side of a
metal
pail and use the lowest
possible fluid pressure during flushing.
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
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 try to 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
or below
Hose Grounding Continuity
fluid 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 can pinch or amputate your fingers or other
body parts. KEEP CLEAR of moving parts when starting or
operating the sprayer. Unplug the sprayer and relieve pressure
before checking or servicing the sprayer to prevent it from
starting accidentally.
