1.1. Removal Procedure

Removal Procedure

  1. Relieve the pressure in the hydraulic system. Refer to Testing and Adjusting, "Release of Pressure in the Hydraulic System".

    ------ WARNING! ------

    At operating temperature, the hydraulic tank is hot and under pressure.

    Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin.

    Before removing the filler cap, press the valve relief button on the hydraulic tank in order to relieve the tank pressure.

    Remove the filler cap only when the engine is stopped and the filler cap is cool enough to touch with your bare hand. Remove the filler cap slowly in order to relieve any remaining pressure.
