MAINTENANCE PROCEDURE 4.9.3.c CHANGING THE FUEL FILTER ELEMENT (WITH WATER SEPARATOR) Engine is at high temperature immediately after the machine has been operated. Wait for engine to cool down before replacing the filter. Do not bring fire or sparks near the fuel. Oils, filters, coolants and batteries are considered special waste and must be collected and disposed of according to the regulations in force. Prepare a filter wrench Prepare a container to gather the fuel. 1. Open the engine rear cover. (For further details, see para- graph "3.2.9 ENGINE REAR COVER". 2. Set the container to catch the fuel under the filter element and element cup. 3. Close valve (1) at the top of the filter (pos.
A). 4. Using a filter wrench, turn filter element cup (2) counter- clockwise to remove it. 5. Clean the filter holder, fill the new filter element cup with fuel, coat the packing surface with engine oil, then install it to the filter holder. 6. Tighten the filter ring until the gasket makes contact with the filter carrier surface, then give a further 2/3 turn. IMPORTANT If the filter element cup is tightened too far, the packing will be damaged and this will lead to leakage of fuel. If the filter element cup is too loose, fuel will also leak from the packing, so always tighten to the correct amount. 7. Open the valve (1) on top of the filter (pos. B). 8.
After replacing the fuel filter element, bleed air. For details of the procedure, see “Air Bleeding“. BLEEDING THE CIRCUIT 1. Fill the fuel tank. 2. OPEN the valve (1) on top of the filter (position B). 3. Turn the starting switch to the ON position, hold it there for 10 to 15 seconds, then return it to the OFF position. Air bleeding is carried out automatically by the automatic air bleed device. NOTE When the machine has run out of fuel, carry out the same procedure, to bleed the air. 197 WARNING
