OPERATION MACHINE OPERATIONS AND CONTROLS Hydraulic Oil Level - Check/Add WARNING When removing the oil filler cap, oil may spurt out, so turn the cap slowly to release the internal pressure before removing the cap. 1. If the work equipment is not in the condition shown in the diagram on the right, start the engine, run the engine at low speed, retract the arm and bucket cylinder rods fully, then lower the boom, set the bucket teeth in contact with the ground, and stop the engine. 2. Open the door of the pump room on the right side of the machine, and check sight gauge (G). The oil level should be between the H and L lines. NOTICE Do not add oil above the H line.
This will damage the hydraulic circuit or cause the oil to spurt out. If oil has been added to above the H level, stop the engine and wait for the hydraulic oil to cool down, then drain the excess oil from drain plug (P). 3. If the level is below the L mark, remove the upper cover of theb hydraulic tank and add oil through oil filler (F). 3-39
