FAILURE TO HEED THE FOLLOWING WARNINGS INCLUDING MISUSE, OVER PRESSURIZING, MODIFYING
PARTS, USING INCOMPATIBLE CHEMICALS AND FLUIDS, OR USING WORN OR DAMAGED PARTS, MAY RESULT
IN EQUIPMENT DAMAGE AND/OR SERIOUS PERSONAL INJURY, FIRE, EXPLOSION, OR PROPERTY DAMAGE.
• Do not exceed the stated maximum working pressure of the pump, or of the lowest rated component in your system.
• Do not alter or modify any part of this equipment.
• Do not operate this equipment with combustible gas.
• Do not attempt to repair or disassemble the equipment while the system is pressurized.
• Make sure all grease connections are securely tightened before using this equipment.
• Always read and follow the grease manufacturers recommendations regarding grease compatibility, and the use of
protective clothing and equipment.
• Check all equipment regularly and repair or replace worn or damaged parts immediately.
• Never point the dispensing valve at any part of the body or at another person.
• Never try to stop or deflect material from dispensing valve or leading connection or component with your hand or body.
• Always check equipment for proper operation before each use, making sure safety devices are in place and operating
properly.
• Always follow the pressure relief procedure after shutting off the pump, when checking or servicing any part of the
system, and when installing, cleaning or changing any part of the system.
Purging and priming the pump
When operating the pump for the first time, or after changing
lubricant containers, see the instructions below.
1. Make sure there is sufficient lubricant in the drum or pail.
Make sure that all hose and fitting connections are tight
and leak proof.
2. The use of an air filter, regulator, and lubricator (F.R.L.)
with these pumps is highly recommended to control the
pressure of the lubricant and protect the pumping system.
3. See the priming instructions in the pump operation manual,
(Sec. A5, Pg 83 Series).
4. Apply enough air pressure to the pump so that it operates
slowly.
5. With lubricant in the pail, and the pump operating slowly,
direct the control valve grease coupler into a suitable
container, and open the control valve. Hold the valve open
until grease, free of air, appears in the container.
6. Close the control valve. If the pump is properly primed, the
pump should stall (stop operating). If the pump continues
to run, repeat the above step until it does stall.
7. After pump is fully primed, increase air pressure to 100
PSI. As the pressure is increased, the pump will cycle
several times as the lubricant pressure increases and the
hose expands. This is normal. Check for leaks at all lubri-
cant connections. Be ready to disconnect the air from the
pump if a leak appears. Keep clear of all connections and
hoses until pressure tightness is assured. Once maximum
pressure is reached, the pump should stop cycling.
8. Should a leak occur, disconnect the air supply to the pump,
relieve all pressure from the pump, hoses, and control
valve, and correct the problem. Do not attempt to stop a
leak with pressure on the system.

Operation

Inspect the entire lubrication pump and attached hoses and
valves before every use. Do not operate this lubrication pump
if any damage appears to the pump or associated compo-
nents. Remove a damaged pump from operation until proper
repairs are made. Contact a factory authorized service center
for parts or repairs.
TO PREVENT PERSONAL INJURY, PERFORM PRES-
SURE RELIEF PROCEDURE AFTER OPERATING THE
PUMP.
1. Adjust the air pressure to the pump for an operating pres-
sure required for the job at hand. Too much pressure
can damage the pump, associated components, or cause
damage to grease seals and other components on the
machinery that is to be lubricated.
2. Make sure that the pump is fully primed and free of air.
Do not operate a pump if the lubricant container is empty
or low on lubricant. A pump that runs out of lubricant
can cause air to enter the grease system or a pump to
run-away, or increase operating speed to the point where
pump damage occurs. Air in the lubricant lines under high
pressure can cause lubricant to be sprayed or splattered
resulting in a hazardous condition.
3. Once primed the pump is ready for use. Adjust the air
pressure to the pump for a smooth flow of grease into the
bearings being serviced.
4. After all bearings have been serviced it is important to
remove air from the pump and discharge the control valve
and hoses at the end of the day. Do not leave the pump
under pressure for extended storage periods.
