OWNERS MANUAL
RETAIN THIS MANUAL FOR FUTURE REFERENCE TO IMPORTANT WARNINGS AND OPERATING
AND MAINTENANCE INSTRUCTIONS.
PROPER USE AND MAINTENANCE OF THIS EQUIPMENT IS THE RESPONSIBILITY OF THE OWNER
AND/OR OPERATOR.
DO NOT USE THIS EQUIPMENT UNLESS YOU HAVE CAREFULLY READ AND
UNDERSTAND THE INSTRUCTIONS AND WARNINGS IN THIS MANUAL.
! WARNING !
NEVER exceed the stated maximum working pressure of the pump or of the lowest rated component in your system.
NEVER modify any part of this equipment.
NEVER use combustible gas with this equipment.
NEVER attempt repairs while the system is under pressure.
NEVER attempt to disassemble the equipment while the system is under pressure.
ALWAYS tighten fluid connections before using this equipment
ALWAYS read/follow the fluid manufacturer’s recommendations regarding fluid compatibility.
ALWAYS read/follow the fluid manufacturer’s recommendations regarding the use of protective clothing and
equipment.
ALWAYS use an air line filter/moisture eliminator at the air inlet for the pump.
ALWAYS use air line lubricator.
REGULARLY check all equipment and repair/replace worn or damaged parts immediately.
FAILURE TO HEED THESE WARNINGS INCLUDING OVERPRESSURIZING,
ALTERING PARTS, USE OF INCOMPATIBLE FLUIDS, MISUSE, OR USE OF
DAMAGED/WORN PARTS MAY RESULT IN EQUIPMENT DAMAGE, PROPERTY
DAMAGE, FIRE, EXPLOSION AND/OR SERIOUS PERSONAL INJURY.
SAFETY INSTRUCTIONS
Extreme caution should be used when operating this equipment as it generates very high fluid pressure. Leaks from
loose or ruptured components or material from dispensing valve can inject fluid through the skin causing serious bodily
injury and possible need for amputation. Always wear protection to prevent material splashing onto skin or into eyes.
IMPORTANT: GET EMERGENCY MEDICAL CARE IMMEDIATELY IF ANY FLUID APPEARS TO
PENETRATE THE SKIN! INFORM PHYSICIAN OF EXACTLY WHAT WAS INJECTED. PLEASE DO NOT
TREAT THIS INJURY AS A SIMPLE CUT.

! WARNING ! – RELIEF PROCEDURE
DO NOT EVER point the dispensing valve at another person.
DO NOT EVER attempt to stop material from the dispensing valve or a leaking connection with your hand or body.
BEFORE EACH USE, check equipment for proper operation and to insure safety devices are in place and working
properly.
NEVER modify this equipment. Modification could cause equipment malfunction and resulting serious bodily injury.
When flushing the pump with solvents, ALWAYS hold a metal part of the dispensing valve firmly to the side of a
grounded metal pail and operate pump at the lowest possible fluid pressure to reduce the risk of injury from splashing
or static sparking.
WARNING: This pump can develop 450 PSI working pressure at 150 PSI maximum incoming air pressure. Be sure
that all system equipment and accessories are rated to withstand the maximum working pressure of this pump.
NEVER exceed the maximum working pressure of the lowest rated component in the system. IMPORTANT:
“Whip” hoses for dispensing valve are fluid pressure rated at 270 PSI. NEVER exceed 90 PSI, air pressure to pump
when using “whip” hoses.
WARNING: Water and even moist air can cause this pump to corrode. To aid in the prevention of this corrosion,
NEVER leave the pump filled with water or air. After normal flushing, flush the pump once more with mineral spirits
or an oil based solvent, relieve pressure and leave the mineral spirits in the pump. It is strongly suggested to put 2-4 fl
oz of Lubricating Oil in the Air Motor Inlet every week for Proper Lubrication. Never use a Synthetic Oil as this will
cause irreparable damage to the pump. BE SURE TO CORRECTLY FOLLOW THE PRESSURE RELIEF
PROCEDURE.
PRESSURE RELIEF PROCEDURE
ALWAYS FOLLOW THIS PROCEDURE to reduce the risk of serious bodily injury, including splashing into the
eyes. After shutting off the pump; checking/servicing any part of the system; installing/cleaning or changing any part
of the system, ALWAYS follow this procedure:
1.Disconnect the air supply to the pump.
2.Aim the dispensing valve away from yourself and others.
3.Aim the dispensing valve into an appropriate container and open until all pressure is relieved.
If you believe that the dispensing valve or hose is completely clogged or that pressure in the pump has not been fully
relieved after following the above procedure, VERY SLOWLY loosen the hose end coupling to relieve the pressure
gradually and then loosen completely. Then proceed to clear the valve or hose.
WARNING: ALWAYS follow the Pressure Relief Procedure after shutting off the pump.
WARNING: ALWAYS follow the Pressure Relief Procedure when checking/servicing any part of the system and
when installing, cleaning or changing any part of the system.
LUBRICATION: It is recommended to lubricate the Air Motor once a week with 2-4fl oz of Common Lubricating Motor Oil
injected into the Airlet port of the Air Motor. This will ensure maximum life of the Air Motor. Never use a Synthetic Oil to Lubricate the Air
Motor and this will swell the Buna-N rubber packings and cause irreparable damage.
INSTALLATION
It is recommended that you use an air line filter/regulator/lubricatorto remove harmful dirt and moisture
from the compressed air supply and to provide automatic lubrication to the air motor. Blow-dry the lines and hoses
with air before connecting them to the system.

Installation and Operation:
The installations indicated on this sheet are for reference and
should be used as a guide only. It is recommended that an air line
filter / regulator / lubricator be used to remove dirt & moisture
from the air supply line and provide lubrication to the air motor.
Before beginning, flush the supply lines & hoses with mineral
spirits or a suitable oil base solvent and blow dry with air before
connecting the lines to your pump. This is to purge any dirt, metal
shavings, contaminants or moisture that might damage the pump or
control valves.
This pump has been tested in oil under both a static and dynamic
pressure test to ensure the pump operates out of the box. It is
recommended that you flush the pump with the fluid you intend to
use so as not to contaminate your environment.
Starting: To start the pump, initiate the main air supply line.
Open the air regulartor slowly until the pump begins to run
smoothly. Open the dispensing valve to allow air to be purged
from the system. Allow the pump to cycle until all of the air is
purged from the system and then release the trigger on the
dispensing valve. The pump will continue pumping until it reaches
stall pressure. Stall pressure is calculated by multiplying the air
pressure on the air regulator by 3; ie 3 x 100 psi so stall pressure is
300 psi of oil pressure. Once the pump reaches stall pressure it
will stop automatically, until the trigger on the dispensing valve is
pulled releasing fluid under pressure and then the pump will start
cycling to build stall pressure again and then stop once stall
pressure is reached again.
Use the air regulator to control the speed of the pump and the fluid
pressure. The recommended operating air pressure is 80 to 100
psi. Anything above 100 psi up to 150 psi reduces pump life
considerably.
If the pump operates rapidly or is running too fast, shut off the air
supply immediately and check the fluid lubricant lines for leaks, if
necessary.
