OPERATING INSTRUCTIONS Continued
Pump with Single-Acting Cylinder
•
Position pump at higher elevation than cylinder.
•
Position cylinder with plunger end down (up if using pull cylinder).
•
Operate pump to fully extend the cylinder (retract if using a pull cylinder).
•
Depress release valve to retract cylinder (extend if a pull cylinder.) This will force the trapped air to
move up to the pump reservoir.
•
Repeat the above steps as necessary.
•
Add oil if necessary.
•
Return vent/fill cap to operating position.
Release Valve Adjustment Procedure
•
Attach pump to air source.
•
Loosen Allen-head screw by turning counterclockwise two full turns.
•
Back out slotted head release valve by turning counterclockwise two full turns.
•
Lift treadle at air inlet end and place your thumb under the treadle on top of air valve button as
illustrated.
•
Using your thumb press down on the air valve button and actuate the pump to build up pressure in the
hose. Hose will become stiff under pressure.
•
Turn slotted-head release valve clockwise until you feel the valve seat against the internal ball.
Excessive tightening will cause loss of pressure in hose.
•
Keep the thumb under treadle to obtain proper operating clearance between the treadle, air valve, and
release valve. Turn Allen-head screw clockwise and tighten firmly to lock valve adjustment.
•
Release valve should now be correctly adjusted to operate the pump properly.
To Change Oil
•
Drain all oil and refill with clean hydraulic oil every 12 months.
•
Remove vent/fill cap or plug from reservoir.
•
Tilt pump to drain old oil.
•
Fill reservoir only to the level mark shown on pump.
•
Replace the vent/fill cap or plug.
•
Dispose of used oil properly.
To Add Oil
•
Turn pump upside down and remove hex filler plug. Tip pump so the hose end is lowest to prevent air
from entering system. Fill reservoir with hydraulic oil and replace filler plug and tighten.
