prIncIple of operatIon
Incoming non-oiled plant air is regulated at 80 PSI*
(5.51 BAR) through the Air Filter/Regulator to the Four-
way Valve, and through the air supply tting on the
manifold.
When a triggering air signal is introduced at the pilot
input on the manifold, the Four-way Valve is shifted,
directing air pressure through the Blue Air Line into the
Power Booster.
As the Power Booster air/hydraulic pistons advance,
hydraulic uid is forced to the hydraulic tting on the
manifold. With 80 PSI*of incoming air pressure, the
hydraulic output pressure will be approximately 3,920
PSI (270.28 BAR)*.
When the triggering signal is released, the Four-way
Valve shifts to its normal position, allowing the air
pressure to return the air/hydraulic pistons to the full
back position
*When using the single-port unit, EPS4, increase the
air pressure to 90 PSI (6.20 BAR), which will yield
approximately 4,410 PSI (304.07 BAR) hydraulic
pressure.

See Figures 2, 2A, and 2B.
Huck recommends conducting periodic inspections on
the Air Filter/Regulator and the Oil Cup Reservoirs.
Check the Air Filter/Regulator bowl for liquid
contaminants, and drain it when checking. This will
aid in maintaining peak performance for the Vacuum
Generator and the Four-way Valve. (Figure 2A)
Periodically check the Hydraulic Fluid Reservoir sight
bowl to ensure the uid level is at 1”. Under typical
operating conditions, this should remain constant. If the
level decreases, check hydraulic components for leaks.
The power unit is shipped with HYDREX™ AW 68
Hydraulic Fluid. Before using an equivalent brand, check
the MSDS for like specications.
