 Danger !

Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running.

Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.

AS00.00-Z-0005-01A

 Danger !

Risk of injury to skin or eyes from hydraulic fluid spraying out under pressure.Risk of poisoning from swallowing hydraulic fluid.

Depressurize hydraulic system completely before starting any work on it. Wear protective clothing and safety glasses.

To do so, slowly close load valve (6) until the measured value on the pressure gage (7) no longer increases, then measure pressure.


Do not fully close load valve (6).
Otherwise, the pump or major assemblies may be damaged.
