Failure to heed the following warnings
may result in personal injury and/or
property damage.
• Always determine the correct air
pressure to operate the lubrication
pump. This pump can develop over
7,500 psi (517 bar). To determine the
air pressure to operate the lubrication
pump, simply divide the rated pressure of the lowest rated component
on the down stream side of the pump
by the lubricant to air pressure ratio of
the pump. Example: The lowest rated
component has a rating of 4,000 psi
(276 bar). If the lubrication pump is a
50:1 pump, divide 4,000 psi (276 bar)
by 50 to determine the correct air
pressure setting, (4,000 psi
(276 bar)/50 = 80 psi (5,5 bar)).
Set the air regulator that controls the
air to the pump to 80 psi (5,5 bar) or
less.
• Never point the control valve at any
part of the body or at another person.
• Never try to stop or deflect material
from the dispensing valve, leaking
connection or component with your
hand.
• Always relieve pressure from the
system before servicing.
• Avoid contact with the nozzle.
WARNING
Appropriate use
The pump is designed to dispense automotive greases directly from the refinery
container. It can be used in a system with
mutiple hose reels and control valves.
Pumps are to be operated with compressed air only. Operation with combustible gasses is prohibited.
Maximum air pressures should not be
exceeded. Failure to heed this warning
may result in serious personal injury,
property damage, and failure of the
pump.
WARNING
Do not use this equipment to pump any
fluids other than the fluids for which it is
designed. Types of fluids not to be
pumped with this equipment include:
• gasoline
• fuel oil
• diesel fuel
• windshield washer solvent
• antifreeze
• brake fluid
• water
Failure to comply may result in serious
personal injury, significant damage to
equipment, and fire or other types of
property damage.
Failure to comply will also result in
loss of claim for warranty or liability.
WARNING
Failure to comply with the warnings listed below may result in serious personal
injury, significant damage to equipment,
and fire or other types of property
damage.
Failure to comply will also result in
loss of claim for warranty or liability.
• Do not alter or modify any part of the
equipment.
Before each use:
• Read and follow fluid manufacturer’s
recommendations regarding fluid
compatibility and use of protective
clothing/equipment.
• Confirm equipment and safety devices
are in place and operating properly.
• Immediately repair or replace any
parts that are found to be worn or
damaged.
• Confirm all grease connections are
tightened securely.
Once system is pressurized:
• Do not attempt to repair, disassemble,
or replace any part of the equipment
without de-pressurizing system first.
• Do not exceed the stated maximum
working pressure of pump or the
lowest pressure-rated component of
the system.
• Do not point dispensing valve at any
part of the body or at another person.
• Do not attempt to block fluid coming
out of dispensing valve, leading
connection, or other component with
any part of the body.
WARNING
Initial pump priming
When the pump is operated for the first
time, the pump will have to be primed.
To prime the pump, remove the grease hose
from the pump lube outlet and set aside.
Connect the airline to the air inlet of the
pump with an air pressure of less than
40 psi (2,76 bar). Slowly increase the air
pressure to the pump until the pump begins
to operate very slowly. Allow the pump to
operate at the slow speed until lubricant
begins to flow out of the pump lube outlet.
After lubricant, free of air begins to flow
from outlet, stop the pump. Attach the high
pressure hose and control valve to the pump
lubricant outlet. Restart the pump and hold
the control valve nozzle in a suitable container while holding the control valve open
to prime the hose and control valve.
Increase the air pressure to the pump as
required, keeping it operating.

Installation
Pumps are tested in light oil before shipment. To avoid system contamination, flush
the pump with the lubricant to be dispensed
before installing the pump.
Flush all supply lines, hoses, reels and fittings used in the dispensing system with
mineral spirits or other petroleum based
solvent to remove dirt, chips and other foreign matter that may damage the pump or
other system components. The components
should be blown dry with air after flushing.
Placement of a low restriction shut-off
valve (such as a ball or gate valve) into the
system between the pump outlet and overhead delivery system is recommended.
This will allow the pump to be isolated from
the system and be removed for service.
Lincoln recommends using a filter/regulator (3/8 in. NPT port size) such as a Lincoln
#602136 in the air supply line to the pump
to regulate the air pressure to the pump.
Lincoln does not recommend using Teflon
tape pipe sealant when making connections
to this pump.
Do not use Teflon tape as sealant for
pump connections.
WARNING
Bung bushing
installation
Thread bung bushing into 2 in. NPT bung on
top of reservoir drum or tank.
(† fig. 1) Tighten bung bushing securely
into bung thread. (fig. 1 illustrates a
55-gallon drum; other containers will be
installed in a similar manner.)
!
Notice
Lincoln recommends using a
filter/regulator (3/8 in. NPT port size)
such as a Lincoln #602136 in the air
supply line to regulate the air pressure
to the pump.
System start-up
When operating the pump in a system for
the first time, purge all air from the system
in order for the pump to prime and operate
reliably. Before connecting the pump to a
system, make sure the pump is placed into a
container of the grease that is to be dispensed. Connect a short length of hose to
the pump outlet and direct the open end of
the hose into a container to catch the
grease. Operate the pump at low air pressure, 40 psi (2,7 bar), until the pump
primes, and grease flows smoothly from the
end of the hose.
The system can now be connected to the
pump outlet. Purge the entire system in a
similar manner, slowly pumping grease
through all reels and control valves until
grease, free of air, flows smoothly from each
outlet.
Pressure relief
procedure
The following procedure should be followed
when it becomes necessary to shut the
system down for service or container
changes.
1 Disconnect the air supply from the inlet of
the pump.
2 Bleed the lubricant pressure off the
system by opening a dispensing valve into
a container. Hold the valve open until all
flow from the system stops.
3 Close the shut-off valve between the
pump and reservoir on standpipe
installations (if present).
4 Close the shut-off valve between the
pump outlet and supply lines (if present).
5 Slowly loosen the lubricant supply line at
the pump outlet. A very small volume of
grease will leak from the threads. If
pressure is present, stop the loosening
procedure and repeat steps 1 through 4.
Pump repair
Repair is limited to the service parts listed
on following pages. In most cases, service is
going to be the replacement of soft seals in
the pump († fig. 5 and 6 for internal
components of the pump, and fig. 7 for
internal components if its an air valve
Contact your nearest authorized Lincoln
service dealer or Lincoln technical services
for assistance.
When ordering replacement parts, order
by part number and description. The model
number and series letter may also be
required.
!
Notice
New outlet body and gasket
New outlet body is designed for a
copper gasket. This gasket replaced the
o-ring that was installed on PMV pumps
manufactured prior to December 2013.
Replace o-ring with copper gasket.
