Models 2385, 2386, 85650
UV INK PUMP TUBE

Attaching Airmotor to Pump Tube

1. Tightly attach tie rods to the airmotor (use short threaded
end of the tie rods).
2. Mount airmotor on top of the pump tube outlet body and
tightly connect Coupling Nut (Item 2) to airmotor piston
rod.
3. Hand tighten tie rods to the pump tube with four nuts
supplied with airmotor.
4. Slowly cycle the pump several times, using just enough
air pressure to operate the pump without stalling.
5. Stop the pump on an "up" stroke and tighten the four nuts
to securely fasten the airmotor to the pump tube.
Operating Precautions
• Use Lincoln replacement parts to assure compatible
pressure rating.
• HEED ALL WARNINGS AND CAUTIONS
• Be sure material hoses and other components are able
to withstand fluid pressures developed by this pump.
• Do not operate pump continuously at speeds in excess
of 75 cycles per minute.
• Disconnect air line from pump airmotor when system
sits idle for long periods of time.
• SERVICING. Before servicing or cleaning pump, or
removing fluid hose or gun from a unit that has been
used, be sure to disconnect air lines and carefully bleed
pressure off of the system.
PREVENT STATIC SPARKING etc.
• Check continuity of all grounding connections with an
ohmmeter.
• PREVENT FIRES. When pumping, flushing or recircu-
lating volatile solvents, the area must be adequately
ventilated.
• Keep solvents away from heat, sparks and open
flames.
• Keep containers closed when not in use.
Do not stall pump against pressure when pumping UV
ink.
IMPORTANT: Stalling the pump against pressure while
pumping UV ink will cause gland leakage and lead to
damage. It is strongly recommended that no shut-off valves
be installed in the output line so that the pump cannot be
inadvertently stalled against pressure.

Pump Priming

To begin operation, the pump must be primed with the
pumped material. The UV Ink pump is a single acting
(pumps material on the "down" stroke) positive displace-
ment reciprocating pump and intakes material only on the
"up" stroke.
To prime pump slowly open the air supply valve until pump
starts. Allow pump to cycle very slowly until all air is pushed
out of the lines and material fills the pump and lines. Close
air supply valve.
Note: Pumps are factory tested with oil and some of it is left
in to protect the pump parts during storage and transporta-
tion. To prevent contamination of material to be pumped,
flush pump before using.

Maintenance and Repair

Relieve pressure from the pump and supply lines and
remove or lockout air line to the airmotor before servicing or
repairing the pump to reduce the risk of an injury from
injection, spraying fluid or moving parts.
Always use Lincoln parts for service and repair.
