Personal injury can result from hydraulic oil under pressure. Hydraulic oil under pressure can cause injury to persons on or near the machine when the pressure is suddenly released. At operating temperature, the hydraulic oil tank is hot and under pressure. Hot oil can cause burns. Remove the fill plug only when the engine is stopped, and the fill plug is cool enough to touch with your bare hand. Do not allow hot oil or components to contact skin. |
