4.7.7.e CHANGING THE ENGINE OIL
DANGER
•
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.
•
The oil that may be spilled during the change makes the
ground slippery, therefore, use anti-slip shoes and imme-
diately remove any trace of oil from the floor.
•
Oils, filters, the coolant and the battery are considered
special waste and must be collected and disposed of ac-
cording to the anti-pollution regulations in force.
Proceed as follows:
1 - Open the engine hood (See “3.5.1 ENGINE HOOD”).
2 - Remove the drain plug (1) of the oil pan, gathering the used
oil that flows out into a container with suitable capacity. (Use
a 19 mm hexagon spanner).
While the oil flows out, remove the filling cap (2), so that the
oil can flow freely.
3 - Tighten the plug (1) onto the pan and pour the prescribed
quantity of new oil, using the dipstick (3) to make sure that
the oil reaches the MAX. level.
To top up, use oil suitable for the ambient temperature (See
“4.3 FUEL, COOLANT AND LUBRICANTS”).
4 - Put back the filling cap (2), start the engine, let it run for 5
minutes and then stop it.
Check the level again and top up if necessary.
5 - Close the engine hood.
