2. The pump handle is raised, which creates a vacuum in
the piston chamber which sucks oil from the reservoir
into the chamber.
3. 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.
4. Steps 2 & 3 are repeated, which will pump oil into
the system until the maximum pressure of 10,000 psi
(700 bar) is achieved, at which point the safety re-
lease valve will open and the oil will cycle back to the
reservoir.
