Be careful not to make a mistake in the direction of hose connections or in the direction of travel of the loader.
(If misconnected, the flow meter, LST pump and/or LST motor will be damaged.)
3. Open the loading valve of the flow meter, start the engine at idle speed and make sure there are no leaks.
