SAFETY
Read and carefully obser e these operating instructions
before operating the Air Pump. The pump must be operated,
maintained and repaired exclusi ely by person familiar with
the operation instructions. Operate the pump only after
safety instructions and this operation manual is fully
understood.
Adequate personal protection is recommended to pre ent
splashing of material on the skin or in the eyes.
Always disconnect air coupler from pump when the pump is
not being used.
Always wear eye protection.
If any fluid appears to penetrate the skin, get emergency
medical immediately. Do not treat injury as a simple cut.
Tell attending physician exactly what fluid was injected.

DESCRIPTION
Models 4475 and 4480 are an air operated single acting
pumps for dispensing low and medium elocity fluids from
drum or other tank. The pumps are self priming. Model
4480 pump is supplied with a spigot tube and 1/4 turn
dispensing al e to transfer fluid into a manageable
container such as a 5 qt. can. All Models ha e a 36 suction
tube with a foot al e to maintain prime.
IMPORTANT: The pump will lose prime without the foot
al e. Contact Lincoln Technical Ser ice for any modification
of the tube .
APPROPRIATE USE
Before using pump
The pump was designed to pump the low and medium
elocity fluids using compressed air. The maximum
specification rating should not be exceeded. Any other use
not in accordance with instruction will result in loss of
claim for warranty or liability.
NOTE: Do not allow pump to operate when out of material.
The pump may be damage as a result.

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 EQUIPMENT DAM-
AGE 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 or fuel, gasoline, diesel fuel, kerosene, etc.
 Do not attempt to repair or disassemble the equipment while the system is pressurized.
 Make sure all fluid connections are securely tightened before using this equipment.
 Always read and follow the fluid manufacturers recommendations regarding fluid compatibility, and the use of
protecti e clothing and equipment.
 Check all equipment regularly and repair or replace worn or damaged parts immediately.
 Ne er point the dispensing al e at any part of the body or at another person.
 Ne er try to stop or deflect material from dispensing al e or leading connection or component with your hand or body.
 Always check equipment for proper operation before each use, making sure safety de ices are in place and operating
properly.
 Always follow the pressure relief procedure after shutting off the pump, when checking or ser icing any part of the
system, and when installing, cleaning or changing any part of the system.
Annual inspection by a factory authorized ser ice center is
recommended.
INSTALLATION
Typical bulk tank and drum system hookups are shown and
described as follows only as a guide in selecting and
installing a system. Contact a Lincoln factory representati e
for assistance in designing a system for a specific require-
ment.
Lincoln recommends using Mini-regulator 602003 (1/4 port
size) with Gage 247843 and 1/4 I.D. Air line supply. See
Figure 3.
SPIGOT APPLICATIONS
Make sure all connections are tight. Thread the pump tube
into the 3/4 NPT material inlet of the pump as shown in
Figure 1.
Loosen the bung collet and install the bung bushing into the
2 NPT fitting of your drum or tank. Slide the pump and
pump tube into the bung collet and adjust to desired height.
Make sure all connections are securely tightened.
To start pump in spigot applications, turn on the main air
supply. Slowly open the air regulator. Regulate air pressure
from 20-40 psig. Open the dispensing al e 1/4 turn to allow
air to be purged from the system. Allow pump to cycle until
fluid without air pockets flows from dispensing al e, then
close dispensing al e.
In a direct supply system, with adequate air pressure
supplied to the motor, the pump starts when the 1/4 turn
dispensing al e is opened and stalls against pressure
when it is closed.
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
pre ent possible contamination of the fluid you are
pumping.
Clean/flush the supply lines, hoses, reducers, connectors
and accessories with mineral spirits or oil based sol ent to
purge any contaminants such as dirt, moisture, or metal
sha ings that could damage the pump or system
components. Blow dry with air.
To reduce the risk of injury from splashing or static
sparking when flushing the pump with sol ents, always
hold a metal part of the dis-pensing al e firmly to the
side of a grounded metal pail and operate at lowest
possible fluid pressure.

SYSTEM APPLICATIONS
To start the pump in a system application, air must be
purged from the system before installing. Connect the
pump outlet to a short 1/2 NPT hose. Turn on the main air
supply, and slowly open the air regulator. Regulate the air
pressure from 20-40 psig. Allow the pump to cycle until fluid
without air pockets flows from the outlet hose. Disconnect
the outlet hose and connect the primed pump to the system,
as shown in Figure 2.
PRESSURE RELIEF PROCEDURE
Always perform this procedure when the pump is shut off
and before checking, ser icing, installing, cleaning or
repairing any part of this system.
Perform the following procedure:
A. Close the dispensing al e 1/4 turn.
B. Disconnect air supply to the pump.
C. Point dispensing al e away from yourself and others.
D. Open the dispensing al e into an appropriate container
until the pressure is relie ed.
If the abo e procedure does not relie e the pressure, the
dispensing al e or hose may be restricted. To relie e the
pressure, ery slowly loosen the aerator from the 1/4 turn
dispensing al e. Then loosen completely and clear the
dispensing al e.
REPAIR
Repair is limited to replacement of listed ser ice parts.
Special procedures and tools are required. Contact Lincoln
Customer Ser ice, One Lincoln Way, St. Louis, MO 63120-
1578, [phone] for your nearest authorized ser ice
center.
When ordering replacement parts, list: part number,
description, model number and series letter.
NOTE: Lincoln recommends
using a tank mounted hose
reel versus an overhead
mounted reel.
