4.9.6 MAINTENANCE EVERY 500 HOURS OF OPERATION
4.9.6.a CHANGING THE ENGINE OIL AND THE ENGINE OIL FILTER CARTRIDGE
WARNING
q Change the oil with the machine parked on a level surface and the work equipment resting on the
ground.
q Soon after the machine has been stopped the engine oil is very hot and may cause burns; let the engine
cool down until it reaches a temperature of 40–45°C before draining the oil.
q The oil that may be spilled during the oil change will make the ground slippery: use anti-slip shoes and
immediately remove any trace of oil from the floor.
q Oils, filters, the coolant and the battery are considered special waste and must be collected and dis-
posed of according to the regulations in force.
Proceed as follows:
1. Open the engine hood (see "3.2.6 ENGINE HOOD").
2. Remove the drain plug (P) of the engine oil pan, gathering
the used oil that flows out of it into a container with suitable
capacity.
While the oil flows out, remove the filler cap (F), so that the oil
can flow out freely.
3. Screw the plug (P) onto the engine oil pan.
4. Using a filter wrench, unscrew the old filter (1) and reject it.
5. Clean the contact surface between the seal and the filter sup-
port (2).
6. Lubricate the seal of the new filter and tighten until it rests
against the gasket.
7. Give another half turn by hand.
8. Fill the engine with the prescribed quantity of new oil, using
the dipstick (G) to check that the level reaches the MAX. ref-
erence mark. 
Use oil suitable for the ambient temperature (see "4.4 FUEL,
COOLANT AND LUBRICANTS").
9. Put back the filler cap (F), start the engine and stop it after 5
minutes.
Check the level again and top up, if necessary.
10. Close the engine hood.
Start the engine, make sure that there are no leakages and that
the engine oil pressure warning light goes out.
IMPORTANT
q Do not use the wrench to lock the filter, in order to avoid
damaging the filter itself and causing oil leakages.
