Hydraulic oil pressure can remain in the hydraulic system on this machine after the engine and pump have been stopped. Serious injury can result if this pressure is not released before any service is done on the hydraulic systems. In order to prevent possible injury, release the hydraulic system pressure before working on any fitting, hose, or hydraulic component. Lower all attachments to the ground before service is started. If the hydraulic system must be serviced, tested, or adjusted with the attachment in the raised position, the attachments and lift cylinders must be supported properly. Always move the machine to a location away from the travel of other machines. Be sure that other personnel are not near the machine when the engine is running and tests or adjustments are being made. |
Note: Put identification marks on all hose assemblies and on all harness assemblies for installation purposes. Plug all hose assemblies. This helps to prevent fluid loss, and this helps to keep contaminants from entering the system.
- Release the system pressure. Refer to Operation and Maintenance Manual, "System Pressure - Release".
