MENT 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 prop-
erly.
· 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.
INSTALLATION
Typical drum and pail hookups are described as follows only as
a guide in selecting and installing a system.
Contact a Lincoln factory representative for assistance in de-
signing a system for a specific requirement.
This pump can develop 7500 PSI working pressure at 150
PSI maximum incoming air pressure. Be sure that all system
equipment and accessories are rated to withstand the maxi-
mum working pressure of this pump.
DO NOT exceed the maximum working pressure of the low-
est rated component in the system.
IMPORTANT: Accessory item whip hoses for dispensing
valve are rated 4500 PSI. DO NOT exceed 90 PSI air pres-
sure to pump when using whip’ hoses.
TYPICAL SYSTEM HOOKUP
Determine the drum or pail system for your requirement.
Obtain an air line filter/regulator/lubricator to use with the inlet
air supply and the correct sized air and grease lines hoses with
any required reducers, connectors and
accessories.
Clean/flush the supply lines, hoses, reducers, connectors and
accessories with mineral spirits or oil based solvent to purge
any contaminants such as dirt, moisture, or metal shavings
that could damage the pump or system
components. Blow dry with air.
The pump was tested in lightweight oil which was left in
to protect the pump from corrosion. Flushing the pump
before connecting it to the system might be desired to
prevent possible contamination of the grease you are
pumping.
To reduce the risk of injury from splashing or static spark-
ing 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 lowest possible
fluid pressure.
Clean/flush the pump with mineral spirits or oil based solvents
if necessary.
Assemble the cleaned pump and supply line together with any
required accessory.
Mount the assembled pump to the drum or pail.
Connect the material output line/hose to the pump.
Connect the air regulator to the pump.
Make sure all connections are securely tightened.

OPERATION
INSPECTION BEFORE USING PUMP
Prior to operation or maintenance a visual inspection shall be
made. Check pump system for leaks, worn or missing parts.
Any pump that appears to be damaged in any way, is badly
worn or operates abnormally shall be removed from use until
repairs are made. Contact a factory authorized service center
for repairs.
If overpressurizing of the equipment is believed to have oc-
curred, contact a factory authorized service center for inspec-
tion of the pump.
Annual inspection by a factory authorized service center is
recommended.
To prevent personal injury, perform PRESSURE RELIEF PRO-
CEDURE before and after operating the pump.
To start pump, turn on the main air supply. Slowly open the air
regulator. Regulate air pressure from 20-40 psig and throttle
to prime pump. Open the dispensing valve to allow air to be
purged from the system. Allow pump to cycle until grease
without air pockets flows from dispensing valve, then close
dispensing valve.
After pump is primed, adjust air pressure to achieve a smooth
flow of grease from the 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 the pump.
If the pump accelerates quickly or is running too fast, stop it
immediately. Check the grease supply and refill it if
necessary. Prime the pump to remove all air from the system,
or flush the pump and relieve pressure.
In a circulating system, the pump runs continuously and slows
down or speeds up as supply demands, until the air supply is
shut off.
In a direct supply system, with adequate air pressure supplied
to the motor, the pump starts when the gun or dispensing valve
is opened and stalls against pressure when it is closed.
Use the air regulator to control pump speed and grease pres-
sure. Always use the lowest pressure required to achieve the
desired results. Higher pressures will cause pump packings to
wear prematurely.
MAINTENANCE
To prevent personal injury, perform PRESSURE RELIEF
PROCEDURE before and after operating the pump and be-
fore any maintenance.
LUBRICATION
An air line filter/regulator/lubricator is recommended for use with
your Lincoln pump to remove harmful dirt and moisture from
your compressor air supply, and to provide automatic air motor
lubrication.
If an air line lubricator is not used, the following procedure should
be performed daily:
A. Disconnect air coupler from air fitting.
B. Fill air coupler with NO. 10 SAE motor oil and reconnect to
air fitting.
C. Operate pump to distribute lubricant.
To reduce the risk of injury from splashing or static sparking
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 lowest possible fluid pres-
sure.
MATERIAL RESTRICTION PREVENTION
Flush the system as required with a compatible solvent to prevent
material buildup when pumping material that dries or hardens.
CORROSION PREVENTION
To prevent water or air corrosion, never leave the pump filled
with water or air. Flush the pump first with a compatible solvent
and then again with mineral spirits or oil based solvent.

To prevent personal injury, perform PRESSURE RELIEF
PROCEDURE before and after operating the pump and
before performing any disassembly or assembly.
A. Remove valve cap (11470), trip rod pin (11472) and trip
collar (11471). Unscrew trip sleeve (11947) from trip rod
(90691).
B. Unscrew four tie rod nuts (51009) from tie rods (10294) and
lift air valve casting (237562) off of air cylinder (61041).
C. Remove packing nut (11904) and packing cap (11905) from
air valve casting.
NOTE
If complete disassembly is required, order the repair kit and
replace ALL gaskets, 0-rings and packings.
D. Remove four valve cover screws (236868) and cover
(236286).
E. Remove four socket head screws (236869), toggle assem-
bly (91331), trip shoe (11475) and trip sleeve (11947).

ASSEMBLY
To reassemble, perform DISASSEMBLY procedures in re-
verse. Tighten fasteners per stated torque specifications.
IMPORTANT: To prevent damage to air piston packing and
pump gland packing, and help to increase packing life, lubri-
cate air cylinder and air piston rod before assembly. Thread
piston rod through gland packing when assembling pump.
Make sure that washer (245869) is completely flat on shoulder
of Pump Tube. See DETAIL for correct distance of washer
from end of Pump Tube.
Before tightening four valve seat screws (236870), align valve
slide and seat plate (83063), slide valve gasket (38162) and
air valve casting (237562) by placing a rod through the center
hole.
REPAIR
Start all fasteners by hand to avoid stripping threads when
reassembling.
Repair is limited to replacement of listed service parts. Special
procedures and tools are required. Contact Lincoln Customer
Service, One Lincoln Way, St. Louis, MO 63120-1578, (314)
679-4300 for your nearest authorized service center.
When ordering replacement parts, list:
part number, description, model number and series letter.
PRESSURE RELIEF PROCEDURE
Always perform this procedure when the pump is shut off and
before checking, servicing, installing, cleaning or repairing any
part of this system.
Perform the following procedure:
A. Disconnect the air supply to the pump.
B. Point the dispensing valve away from yourself and others.
C. Open the dispensing valve into an appropriate container
until the pressure is relieved.
If the above procedure does not relieve the pressure, the
dispensing valve or hose may be restricted. To relieve the pres-
sure, very slowly loosen the hose end coupling. Then loosen
completely and clear the dispensing valve and/or hose.
DETAIL
Caution: Do not exceed 15 Ft. Lbs.
