CLOSE RELEASE
VALVE
The pump handle is raised, which creates a vacuum in
the piston chamber which sucks oil from the reservoir
into the chamber
The pump handle is depressed, which pumps the oil from
the chamber through the outlet port and into the system
to which the pump is connected
Steps 2 & 3 are repeated, which will pump oil into
the system until the maximum pressure of 700 bar
(10 000 psi) is achieved, at which point the safety release
valve will open and the oil will cycle back to the reservoir
