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 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.
If you experience any static sparking or even
while using this equipment, STOP SPRAYING IMMEDIATE-
LY. Check the entire system for positive 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 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. Pump: use a ground wire and clamp as shown in 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:
through connection to a properly grounded fluid hose and
6. Object being sprayed: according to your local code.
7. A// solvent pails used when flushing, according to local
code. Use on/y metal pails, which are conductive, placed
on a grounded surface. Do not place the pail on a non-
conductive surface, such as paper or cardboard, which in-
terrupts the grounding continuity.
8. 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 grounded metal pail, then trigger the
gun/valve.
High pressure fluid in the hoses can be very dangerous. If the
hose develops a 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 injury or pro-
ALL FLUID SPRAY HOSES MUST HAVE SPRING
(except certain mastic applications) 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.

To ground the pump, loosen the grounding lug ocknut (A)
and washer (B). Insert one end of a 12 ga (1.5 m A ) minimum
ground wire (C) into the slot in lug (D) and tighten locknut
securely.. See the drawing above. Connect the other end of
the wire to a true earth ground. Refer to page 9 to order a
ground wire and clamp.
Safety
To reduce the risk of injection injury, static sparking, or
splashing in the eyes or on the skin, follow the Pressure

the side of a grounded meta/ pail and use the lowest possible
fluid pressure during flushing.
MOVING PARTS HAZARD
The piston in the air motor, located behind the air motor
plates, moves when air is supplied to the motor. Moving parts
can pinch or amputate your fingers or other body parts.
Therefore, NEVER operate the pump with the air motor plates
removed. KEEP CLEAR of moving parts when starting or
operating the pump. Before checking or servicing the pump,

HANDLE AND ROUTE HOSES CAREFULLY. Do not pull on
hoses to move equipment. Do not use fluids or solvents which
are not compatible with the inner tube and cover of the hose.
Hose Groundin
Continuity
Proper hose groun 8 ing continuity is essential to maintaining a
grounded spray 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 supplier or manufacturer for the
maximum resistance limits. Use a resistance meter in the ap-
propriate range for your hose to check the resistance. If the
resistance exceeds the recommended limits, replace it im-
mediately. An ungrounded or poorly grounded hose can make
your system hazardous. Also, read FIRE OR EXPLOSION
