  1. Position the Backhoe so that the Stick (1) is fully extended and lowered to the ground.

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

    Personal injury can result from hydraulic oil pressure and hot oil.

    Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.

    Make sure all of the work tools have been lowered to the ground, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.

    ----------------------

  1. Remove the work tool from the host machine. Refer to Operation and Maintenance Manual, "Installation and Removal" for the removal process.

    Note: Put identification marks on all lines and on all fittings for installation purposes. Plug all lines. This will help to prevent fluid loss and this also helps to keep contaminants from entering the system.

  1. Disconnect two lines (2) for the bucket cylinder.
