At operating temperature, the hydraulic oil is hot and under pressure. Hot oils can cause burns. To prevent possible personal injury, release the pressure in the work tool hydraulic circuit (boom, stick, bucket, and swing), travel circuits, and the hydraulic oil tank at the filler cap before any hydraulic lines or components are disconnected or removed. Remove the filler cap only when the engine is stopped and the filler cap is cool enough to touch. |

Personal injury can result from the sudden release of high pressure oil. Be sure the engine has been shut off for a minimum of five minutes to ensure that the accumulator pressure is zero. The accumulator is filled with dry nitrogen. Do not loosen or remove the valve or the cap from the top of the accumulator. |
