Hydraulic System Pressure - Release
Procedure for Releasing Pressure
Release the pressure in the travel circuits before any hydraulic lines or components are disconnected or removed from the travel circuit.
- Park the machine on a flat, level surface.
- Lower all the implements as flat on the ground as possible.
- Stop the engine.
- Turn the engine start switch to the ON position without starting the engine.
- In order to relieve any pressure that might be present in the pilot system, move the implement control and travel control levers or pedals to FULL STROKE positions.
- Turn the engine start switch to the OFF position.
- Slowly loosen the fill/vent plug on the hydraulic oil tank and release the pressure.
- Tighten the fill/vent plug on the hydraulic tank.
- The pressure in the system should now be released. The hydraulic lines and/or hydraulic components can now be removed.
