Pressure relief
procedure
Always perform this procedure before
servicing:
1 Disconnect air supply to pump.
2 Point dispensing valve away from yourself
and others.
3 Open dispensing valve into container until
pressure is relieved.
If above procedure does not relieve pressure,
dispensing valve or hose may be restricted.
To relieve pressure, very slowly loosen hose
end coupling. Then, loosen completely and
clear dispensing valve and/or hose.
Operation
Inspect before use
Any pump that appears to be damaged in
any way, shall be removed from use until
repairs are made. Contact factory authorized
service center for repairs.
Pump use
To start pump, turn on main air supply.
Slowly open air regulator. Regulate air
pressure from 20–40 psi (1,3–2,7 bar) and
throttle to prime pump. Open dispensing
valve to allow air to be purged from system.
Allow pump to cycle until grease, without air
pockets, flows from dispensing valve, and
then close dispensing valve.
After pump is primed, adjust air pressure
to achieve smooth flow of grease from
dispensing valve. Do not allow pump to
operate when out of material. Pump will
accelerate quickly and run too fast, resulting
in costly damage to pump.
If pump accelerates quickly or is running
too fast, stop it immediately. Check grease
supply and refill it if necessary.
In circulating system, pump runs
continuously and slows down or speeds up
as supply demands, until the air supply is
shut off.
In direct supply system, with adequate air
pressure supplied to motor, pump starts
when gun or dispensing valve is opened and
stalls against pressure when it is closed.
Use air regulator to control pump speed
and grease pressure. Always use lowest
pressure required to achieve desired results.
WARNING
Do not operate pump or system with
pressure applied. Perform pressure relief
procedure prior to starting pump.
Failure to comply may result in serious
injury or damage to equipment.
WARNING
Failure to heed the following warnings
including misuse, over pressurizing, modify-
ing parts, using incompatible chemicals and
fluids, or using worn or damaged parts, may
result in serious personal injury and/or
equipment damage, fire, explosion, or prop-
erty damage.
• Do not exceed the stated maximum work-
ing 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 com-
bustible 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 manu-
facturers recommendations regarding
grease compatibility, and the use of pro-
tective 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, leading connection or
component with your hand or body.
• Always check equipment for proper opera-
tion 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.
