5-2 Pressure and piping ① Composition of hydraulic equipment system WARNING When a pump, high-pressure hose(s), cylinder, valve, couplings are connected together, always check product limitations regarding pressure ratings and load capacities. The system operating pressure must not exceed the pressure rating of the lowest rated component in the system.

Range of standard pressure adjustment available is form 58.8 to 68.6MPa. different kind of a spring is needed to adjust and set at lower pressure than the standard. Contact NITTOH authorized distributor. Loosen lock screw on the relief valve and turn the adjusting screw a few turns counter-clockwise to decrease pressure setting to a lower desired pressure.
