Start By:

Release the pressure in the hydraulic oil system. Refer to Disassembly and Assembly, "Hydraulic System Pressure - Release".

Note: Cleanliness is an important factor. Before the disassembly procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism.

Note: Put identification marks on all lines, on all hoses, on all wires, and on all tubes for installation purposes. Plug all lines, hoses, and tubes. This helps to prevent fluid loss and this helps to keep contaminants from entering the system.

Show/hide table

Cylinders equipped with lock valves can remain pressurized for very long periods of time, even with the hoses removed.
Failure to relieve pressure before removing a lock valve or disassembling a cylinder can result in personal injury or death.

Ensure all pressure is relieved before removing a lock valve or disassembling a cylinder.
