Show/hide table

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. Put identification marks on all lines, on all hoses, and on all tubes for installation purposes. Plug all lines, all hoses, and all tubes in order to prevent fluid loss and help keep contaminants from entering the system.

2. Before starting the removal procedure, ensure that the hitch cylinder is fully retracted.
