At operating temperature, the oil in the power train is hot and under pressure. Hot oil can cause burns. Remove the breather filter cap when the engine is stopped and the breather cap is cool enough to touch by hand. Slowly loosen the breather filter cap in order to release any pressure in the oil tank. Be careful of hot hydraulic oil when any lines are disconnected from the components of the power train. |

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.
