5 Maintenance 5-1 Hydraulic working oil ① Kind of oil Use only Nittoh NHO-32 hydraulic oil or an approved, high-grade oil (ISO #32, viscosity : 32 cSt @40°C) with these pumps to promote long pump life. ② Oil temperature Aptitude temperature for use of hydraulic oil is max. 55 ° C. In case it happens unacceptable rise in oil temperature, stop working so as to decrease oil temperature or take such a measure as installation of an oil cooler. - Page 8 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.
- Page 9 150 hours or more subject to the conditions of their uses. Use only NITTOH carbon brushes with these pumps to promote long pump life. When they have been worn down, the spring exerts insufficient pressure to hold brush against the commutator.
- Page 10 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.
