Removal Procedure
Start By:
- Release the hydraulic system pressure. Refer to, "System Pressure - Release".
 |
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. |
 |
- Position the bucket on the ground.
- Disconnect hose assembly (1) that supplies oil to the head end of the stick cylinder.
