Static electricity is created by the high velocity flow of fluid
through the pump and hose. If every part of the sprayldispen-
sing system 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
substances, whether you are spraying indoors or outdoors,
and can cause a fire or explosion and serious bodily injury and
property damage. Do not plug in or unplug any power supply
cords in the spray area when there is a chance of igniting
fumes still in the air.
If you experience any static sparking or even a slight shock
while usina this eauioment. STOP SPRAYING IM-
MEDIATELIY. Check the entire system for positive ground-
ing. 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 and all
other equipment used or located in the spray/dispensing area.
CHECK your local electrical code for detailed grounding in-
structions for your area and type of equipment. BE SURE to
ground all of these components:
1.
Pump: to ground the pump, loosen the grounding lug
locknut (A) and washer (B). Insert one end of a 12 ga
(1.5 mm*) minimum ground wire (D) into the slot in lug
(C) and tighten locknut securely. See Fig 1. Connect the
other end of the wire to a true earth ground. Check your
local code. See ACCESSORIES, page 6, to order ground
wire and clamp.

Air and fluid hoses: use only grounded hoses with a max-
imum of 500 feet (150 m) combined hose lenath to en-
sure grounding continuity. Refer to Hose Gyounding
Continuity.
Air compressor: follow manufacturer’s recommenda-
tions.
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 metalpails, 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/valve
firmly to the side of a metal pail, then trigger the
gun/valve.
Flushing Safety
Reduce the risk of fluid injection injury, static sparking, or
splashing by following the flushing procedure given on page 5
of this manual. Follow the Pressure Relief Procedure on
page 2, and, for a spray gun, remove the spray tip before
flushing. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail and use the lowest possible fluid
pressure during flushing.
Moving parts can pinch or amputate your fingers or other
body parts. The piston in the air motor, located behind the air
motor shield. moves when air is suoojied to the motor, NEVER
operate the ‘pump with the air motor shield removed. Keep
fingers clear of the priming piston and intake valve while the
pump is operating, to reduce the risk of amputation or injury
to your hand or fingers. Before checking or servicing the
pump, always disconnect the power source and relieve
pressure, following the Pressure Relief Procedure on page
2, to prevent the pump from starting accidentally.

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
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. reolace the hose immediatelv. 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.
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 max-
imum electrical resistance, contact the hose supplier 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 recom-
mended limits, replace it immediately. An ungrounded or
poorly grounded hose can make your system hazardous. Also,
read FIRE OR EXPLOSION HAZARD above.
