    Caution ・Do not move the tank with filling oil. (The oil leaking and air-mixing will cause inferior operation.) ・During transportation, be sure to fix it so that it may not be moved by vibration and another force. DAIKIN INDUSTRIES, LTD.
  • Page 10 ・If the hydraulic unit is not fixed with bolt, it is dangerous because of falling down and moving around by the hydraulic reactive force in the pipes, so the unit must be fixed. Caution ・In case it is installed in the slope, there will be oil-leaking and air-mixing cause unusual noise and shorten equipment’s life. DAIKIN INDUSTRIES, LTD.

  • Page 11: Preparation For Operation

    ・The oil level inside the tank will vary a lot with the different hydraulic circuit on the machine, be careful that if the oil is overflowed from the tank or the oil level is lower than its usual level. DAIKIN INDUSTRIES, LTD.
