    NOTICE

    Never remove the hydraulic tank filler cap from the hydraulic tank if the oil is hot. Hot oil can cause burns.

    Air can enter the system. Air in the system can cause pump damage.


  5. Remove the hydraulic tank filler cap slowly in order to relieve any pressure. Add hydraulic oil, if necessary.

  6. Inspect the gasket on the hydraulic tank filler cap. If the gasket is damaged replace the hydraulic tank filler cap.

  7. Install the hydraulic tank filler cap.
