    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 color of the temperature seal attached to the tank has changed and indicated “55”...
  • Page 7 ③ Oil exchange CAUTION The frequency of oil change will depend upon general working conditions, severity of use and overall cleanliness. 300 hours (working time) of use or about 3 months is considered as a standard change interval. Periodically compare samples oh the reservoir oil with new oil and inspects oil color for contaminants or differences.
  • Page 8 5-3 High pressure hoses ① Hose installation WARNING Install hoses, leaving something in reserve, because high-pressure hoses expand and contract more or less when full pressure is applied. Be careful that the hoses do not rub against other solid materials. Never allow the hoses to kink, twist, curl or bend so tightly that oil flow within hoses are blocked or restricted.
  • Page 9 CAUTION 5-5 Bleeding air from the system Reservoirs of UP-35RH-Series pumps are made of totally enclosed rubber tanks and tank covers. Rubber tanks are filled with oil, making no room for air accumulation. However, in case a new cylinder and / or new hose is connected with the pump, or oil is exchanged, air may accumulate in the hydraulic system.
  • Page 10 ④ If the pump works normally, air in the hose, cylinder and other system is collected in the tank and oil must be replenished. ◎How air may accumulate in the pump (rubber tank) when hydraulic equipment are connected together with? Always check and confirm before use that the oil tank is full.
  • Page 11 150 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.
