Pressure Release Procedure

Show/hide table

Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the work tools have been lowered to the ground, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.

1. Move the machine to a smooth horizontal location that is away from other machines and personnel. Lower all attachments to the ground.

2. Permit only one operator on the machine. Keep all other personnel away from the machine.

3. Engage the parking brake.

4. Stop the engine.

5. Turn the key to the ON position.

6. Move the hydraulic control levers to all positions so that the pressure in the hydraulic system is released.

7. Loosen the filler cap on the hydraulic tank so that the pressure in the tank is released.

8. Tighten the filler cap on the hydraulic tank.

9. The pressure in the system has now been released and lines or components can be removed.
