ATTACHING AIRMOTOR
TO PUMPTUBE
1.Tightly attach tie rods to the airmotor
(use short threaded end of the tie
rods).
2. Mount airmotor ontop of the pump-
tube outlet and tightly connect
Coupling Nut (Item 2) to airmotor
piston rod.
3. Hand tighten tie rods to the pumptube
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 pumptube.

Use Lincoln replacement parts to
assure compatible pressure rating.
HEED ALL WARNINGS
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 airline from pump air-
motor when system sits idle for long
periods of time
SERVICING. Before servicing or
cleaning pump, or removing fluid
hose orgunfrom aunit that has been
used, be sure to disconnect air lines
and carefully bleed pressure off of
the system.
PREVENT STATIC SPARKING.
If static sparking occurs, fire or
explosion could result. Pump,
dispensing valve, and
containers must be grounded
when handling flammable
fluids such as petroleum
products, paints, lacquers, etc.
and wherever discharge of
static electricity is hazard.
Check continuity (a good static wire
connection) with an ohmmeter. Place
one probe on one hose fitting and
theother probe on other hose fitting,
continuity or proper grounding
through hose is good when areading
is obtained on the ohmmeter.
PREVENT FIRES. When pumping,
flushing or recirculating volatile
solvents, the area must be adequately
ventilated.
Keep solvents away from heat, sparks
and open flames. Keep containers
closed when not in use.
NOTE:
Install Item 14 with 5/16” long
thread relief toward Item 3.
Assemble with Loctite Thread-
locker #271 (Red) or equivalent.
Torque to 55-60 ft lbs.
To prime pump, open output line
(material valve) and slowly open air
supply valve until pump starts Allow
pump to cycle very slowly until all air is
DO NOT allow pump to operate
when out of material.
PUMP PRIMING
To begin operation, the pump has to be
primed with the pumped material. The

TROUBLESHOOTING
Problem Possible Cause Solution
Pump does not operate. Restricted or inadequate air supply. Check air supply pressure and air hose
diameter (see Airmotor manual for
minimum air supply hose diameter).
Obstructed material output. Check output line for restrictions.
Erratic or accelerated operation. Pump is not primed. Prime pump (see “Pump Priming”
instructions).
Insufficient material supply. Refill material supply.
Material is too heavy for priming. Lower output with material valve. Increase
pressure to pressure primer (if in use)
Check for inlet restrictions.
Pump operates on “down” stroke only Worn or damaged Piston O-rings (Item 15) Check and replace if needed.
(missing “up” stroke). or Piston Check (Items 16 &17).
