Directions for use

  • Do not remove the oil strainer to keep the pump clear of foreign matter.
  • Replace or clean the suction filter at least once a year. Click here to view the service list.
  • Oil viscosity varies with oil temperature. Be sure to use oil within specified working viscosity range. Click here to view the viscosity list.
  • Do not use any special additive-contained oil, water soluble oil and solvent.
  • Periodically check the oil in the reservoir for impurities. Replace it, if necessary, with fresh oil immediately. Be sure to clean the reservoir before oil change.
  • Make sure that proper voltage and pressure are proper.
  • Do not overtighten the discharge joint.
  • Refer to the tightening torque table.
  • Low-oil viscosity versions are available. Contact us for information.
  • For system planning information, click here.
  • * Should the pump malfunction, Contact us for immediate response with substitution.
