2 Noise, long life The pump and motor shaft are linked by a joint,which minimizes noise by eliminating theeffects of shaft vibration and an off-center shaft. The coupling is constructed to allow constantlubrication, for friction-free long life.

4 Precautions zThe direction of rotation is clockwise(rightward) when viewed from themotor fan side. xAt startup, repeat the inching opera-tion (start-stop) with the pump dis-charge side at no-load to bleed airfrom the pump and suction piping. cEquip an air bleed valve in circuitswhere it is difficult to bleed air beforestartup. vMake sure the maximum peak pres-sure (setting pressure + surge pres-sure) during operation does notexceed 14 MPa.

Normally, you should use an R&O typeand wear-resistant type of ISO VG32 or46, or operating temperature range is 15 to60 C. When the oil temperature at startupis 15 Cor less, perform a warm-up opera-tion at low pressure until the oil tempera-ture reaches 15 C.

6 Use the pump in an area where the tem-perature is within the range of 10 to 35 C. cFor the return line to the tank, use a 25 mline filter. vManage hydraulic operating fluid so cont-amination is maintained at class NAS10 orlower. Take care to avoid contaminationwith water, foreign matter, and other oil,and watch out for discoloration. the Pressure and Discharge Rate zWhen adjusting pressure, pressure isincreased by clockwise (rightward) rota-tion of the adjusting screw and decreasedby counterclockwise (leftward) adjustment is complete, securelytighten the lock adjusting the discharge rate, therate is decreased by clockwise (rightward)rotation of the adjusting screw anddecreased by counterclockwise (leftward)rotation.
