It is the responsibility of the owner and/or
operator to properly use and maintain
this equipment carefully read and under-
stand the instructions and warnings in
this manual before operating this
equipment.
This equipment complies with OSHA
standards where applicable.
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 disassem-
ble the equipment while the system is
pressurized.
Tighten all fluid connections securely
before using this equipment.
Always read and follow the fluid man-
ufacturer’s recommendations regarding
fluid compatibility, and the use of pro-
tective clothing and equipment.
Check all equipment regularly and
repair or replace worn or damaged parts
immediately.
WARNING
Specifications
5:1 ratio, output 6 gal./min. (22 l/min.)
Min. Air pressure 40 psi (2,75 bar)
Max. Air pressure 200 psi (13,8 bar)
Max. output pressure 1,000 psi (68,9 bar)
!Notice
Failure to heed these warnings
including misuse, over pressurizing,
modifying parts, using incompatible
chemicals and fluids, or using worn or
damaged parts, may result in equip-
ment damage and/or serious personal
injury, fire, explosion, or property
damage.
Pressure relief
procedure
Systems which will be dispensing fluids
under pressure may need to be protect-
ed by using a thermal relief kit, which
will safely limit the pressures caused by
thermal expansion. Please contact your
local Lincoln distributor and refer to ser-
vice page section K5, page 31 for more
details. Failure to include thermal relief
protection may cause damage not cov-
ered under Lincoln’s warranty policy.
WARNING
To reduce the risk of serious bodily in-
jury, including splashing in the eyes or
on the skin, always follow this procedure
whenever you shut off the Pump, when
checking or servicing any part of the
system, and when installing, cleaning or
changing any part of the system.
WARNING
1 Disconnect the air to the pump.
2 Point the dispensing valve away from
yourself and others.
3 Open the dispensing valve until pressure
is relieved.
If you suspect that the dispensing valve or
hose is completely clogged, or that pressure
has not been fully relieved after following
the steps above, very slowly loosen the
hose end coupling and relieve pressure
gradually, then loosen completely. Now clear
the valve or hose.

Inspection instructions
If over pressurizing of the equipment is
believed to have occurred contact the factory
authorized warranty and service center
nearest you for inspection of the pump.
Specialized equipment and knowledge is
required for repair of this pump. Contact the
factory authorized warranty and service
center nearest you for repairs or adjust-
ments other than maintenance specified in
this manual.
Annual inspection is recommended by the
factory authorized warranty and service
center nearest you.
A list of factory authorized warranty and
service centers is available upon request.
Damaged pumps
Any pump that appears to be damaged in
anyway, is badly worn or operates abnor-
mally, shall be removed from use until
repairs are made.
Contact the factory authorized warranty
and service center nearest you for repairs.
Operation
Flushing
The pump was tested in lightweight oil,
which was left in to protect the pump from
corrosion. Flush the supply lines and hoses
with compatible solvent and blow dry with
air before connecting them to the system.
This is to purge any contaminates such as
dirt, moisture or metal shavings that could
damage the pump or system components
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.
If the pump accelerates quickly or is run-
ning too fast, stop it immediately. Check the
fluid supply and refill it if necessary. Prime
the pump to remove all air from the system,
or flush the pump and relieve pressure.
Maintenance
If you are pumping fluid which dries,
hardens or sets up, flush the system with a
compatible solvent as often as necessary to
prevent a buildup of dried fluid in the pump
or hoses.
Corrosion protection
for carbon steel pumps
Always follow the pressure relief
procedure warning whenever you
stop spraying and before checking or
repairing any part of the system, to
reduce the risk of serious bodily injury.
WARNING
Do not exceed the maximum working
pressure of any component or accessory
used in the system.
This pump can develop 1,000 psi
(68,9 bar) maximum working pressure,
at 200 psi maximum incoming air
pressure.
Verify all equipment and accessories
are rated to withstand the maximum
working pressure of this pump.
WARNING
Do not clean this system without proper
grounding.
When flushing the pump with sol-
vents, to reduce the risk of injury from
splashing or static sparking, always hold
a metal part of the dispensing valve
firmly to the side of a grounded metal
pail, and use the lowest possible fluid
pressure when flushing.
WARNING
Installation
The typical installation and pump mountings
shown are only a guide for selecting and
installing system components.
Contact your Lincoln representative for
assistance in designing a system to suit your
particular needs.
Mount the pump to suit the type of
installation planned. Refer to the pump
dimensional drawing for mounting layout.
An air line filter/regulator/lubricator is
recommended for use with your Lincoln
pump to remove harmful dirt and moisture
from the compressed air supply, and to
provide automatic air motor lubrication.
Use correct air and fluid hoses for your
system.
Tighten all fluid connections securely
before using this equipment.
!Notice Water and moist air, can
cause your pump to corrode. To
help prevent corrosion, never leave the
pump filled with water or air.
After normal flushing, flush the pump
again with mineral spirits or oil-based
solvent, relieve pressure, and leave the
mineral spirits in the pump.
Follow all steps of the pressure relief
procedure warning.

Replace trip shoe assembly (25), trip sleeve (27) and toggle plate (23)
Air seepage from air exhaust while pump is not operating. Replace valve slide, valve seat (17), valve gasket (16), trip rod packing
(50) and gasket (49) and gasket (48)
Loss of pressure, volume or continuous operation of pump when
not in normal use Clean piston seat and ball foot valve if worn or damaged: Replace piston (58), ball check (65) and piston packing (52). Check inside diameter
of pump tube (59), if scored replace pump tube
Excessive amount of air in lubricant or excessive amount of
lubricant coming from air exhaust. Note: some lubricant exhausts
with air normally
