ATTACHING AIRMOTOR TO PUMPTUBE
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 and tightly
connect Coupling Nut (Item 2) to airmotor piston rod.
3. Hand tighten tie rods to the pumptube with four nuts sup-
plied 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.
OPERATING PRECAUTIONS
•
Use Lincoln replacement parts to assure compatible pres-
sure 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 air line from pump air motor 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. 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 the other
probe on other hose fitting, continuity or proper grounding
through hose is good when a reading 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.
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 Power-Master III pump is a double act-
ing (pumps material on ‘up’& “down” stroke.) positive displace
-
ment reciprocating pump and as such intakes material only on
the “up” stroke.
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 pushed out of lines and material fills
up pump and lines. Close output line (material shut-off valve) -
pump should stall against pressure
Note:
Pumps are factory tested with light oil and some of it
is left in to protect pump parts during storage and transporta-
tion. To prevent contamination of material to be pumped, flush
pump before using.
