At operating temperature, the hydraulic tank is hot and under pressure. Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin. Remove the filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Remove the filler cap slowly to relieve pressure. |

- Use the following procedure to release the pressure in the hydraulic system:
- Lower the implements to the ground.
- Shut off the engine.
- Move the control levers through the full travel distance of the levers. This will relieve any pressure in the pilot system.
- Slowly loosen the filler cap on the hydraulic oil tank in order to release the pressure.
- Tighten the filler cap on the hydraulic oil tank.
- The pressure in the hydraulic system has now been relieved. Lines and components can now be removed.
Note: Put identification on all lines, hoses, wires, and tubes for installation purposes. Install a cap or plug on all lines, hoses, and tubes that are disconnected. The caps and/or plugs prevent the loss of fluid and contaminants cannot enter the system.
