WARNING
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 serious personal injury, and/or equipment damage, fire, explosion, or property
damage.
• Do not exceed stated maximum working pressure of pump or of lowest rated
component in system.
• Do not alter or modify any part of equipment.
• Do not operate equipment with combustible fluids.
• Do not repair or disassemble equipment while system is pressurized.
• Make sure all grease connections are securely tightened before using this equipment.
• Always read and follow grease manufacturer’s recommendations regarding grease
compatibility, and 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, 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.
Pressure relief
procedure
Disconnect air supply to pump.
Point dispensing valve away from
yourself and others.
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
Do not use a pump that appears to be
damaged in any way. Contact factory
authorized service center for repairs.
If overpressurizing of equipment is
believed to have occurred, contact a
factory authorized service center for
inspection of pump.
Annual inspection by a factory authorized
service center is recommended.
WARNING
Do not operate pump or system with
pressure applied. Perform pressure
relief procedure before and after
operating pump.
Failure to comply may result in death
or serious injury.
Pump use
To start pump, turn on main air supply.
Slowly open air regulator. Regulate air
pressure from 20–40 psi (1.4–2.8 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.
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.
Stop pump immediately if accelerates
quickly or is running too fast. Check
grease supply and refill if necessary.
. Circulating systems:
Pump runs continuously and slows
down or speeds up as supply demands,
until air supply is shut off.
. Direct supply systems:
Pump starts when gun or dispensing
valve is opened and stalls against pres-
sure when it is closed (with adequate air
pressure supplied to motor).
Use air regulator to control pump speed
and grease pressure. Always use lowest
pressure required to achieve desired
results.
