Changing the oil in the hydraulic tank
Fig. 672
Oil change:
• Provide a collecting vessel (approx. 150 litres).
• Clean thoroughly around the oil drainage pipe (2).
• Place the end of the oil drain hose (included with the machine) into the collecting vessel.
Mount the other end of the hose onto the oil drain plug (2) of the hydraulic tank (1). This
automatically opens the oil drainage valve and the hydraulic oil drains into the collecting
vessel.
• Remove the drain hose.
• Top up the hydraulic tank with hydraulic oil via the oil filler pipe (2) up to the middle of the
inspection glass. Quantity and specification, see page 33.
• Run the diesel engine at a low idle speed for approx. 10 seconds.
• Switch off the diesel engine.
• Check the oil level in the hydraulic tank; top up the hydraulic oil if required.
• Repeat the process until the oil level no longer drops.
