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 in order to relieve pressure. |

Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. |
Note: Put identification marks on all hose assemblies, on all tube assemblies and on all wire harnesses for installation purposes. Plug all hose assemblies and all tube assemblies. This helps to prevent fluid loss and this helps to prevent contaminants from entering the system.
- Drain the hydraulic tank into a suitable container for storage or disposal. Refer to Operation and Maintenance Manual, "Hoist, Torque Converter and Brake Tank Oil - Change".
