FEATURES
Main Relief Valve
The Main Relief has two adjustments:
1) Standard Main Relief pressure
2) Power Boost Pressure
When pilot signal port is pressurized the power boost piston shifts to the position shown
(POWER BOOST). Thus the pilot spring force rises, and the pressure setting increases.
a) In H or S mode, when the controller activates auto power boost, power boost
operation is executed for 8 seconds.
b) In L mode power boost is on full time.
