1.18 HYDRAULICS COMPONENTS General NOTE: An identification number in bold type, after an item, refers to the number of that item in the main hydraulic schematic illustration. Hydraulic tank (1) A single hydraulic reservoir feeds the main and auxiliary systems of the machine. A sight glass is fitted to check system contents. An internal 40 µ m mesh filter (pre-filtration) separates the clean and dirty sides of the tank. Both system suction lines are taken from the clean side of the mesh filter. All return lines go to a manifold and return fluid to dirty side of tank for pre filtration. Specifications:
