Directions for use

  • Oil viscosity varies with oil temperature. Be sure to use oil within specified working viscosity range. Refer to the viscosity table.
  • Do not use any specal 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 is applied.
  • Do not overtighten the discharge joint. Refer to the tightening torque table.
