Pendant Operation).
The AHP pump is extremely simple to use:
To activate the pump press the button
marked "PUMP" on the hand pendant
(Fig. 16).The pump will start to deliver
pressurized oil and thereby cause the
connected cylinder to advance.
When the button is released, the pump
stops but the pressure is maintained on
the oil side so that the connected
cylinder holds the load in the position it
has reached.
To return the pressure to zero and
hence retract the cylinder to its starting
position,
press the button marked
"RELEASE" (Fig 16).
