4.7.11.c 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 immedi-
ately remove any trace of oil from the floor.
•
Oils, filters, coolants and batteries are considered special
waste and must be collected and disposed of according to
the anti-pollution regulations in force.
When changing the engine oil, change also the oil filter (See
“4.7.11.d CHANGING THE ENGINE OIL FILTER”).
To change the engine oil, 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 spanner).
While the oil flows out, remove the filling cap (2), so that the oil
can flow freely.
3 - Change the filter (See “4.7.11.d CHANGING THE ENGINE
OIL FILTER”).
4 - 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.
5 - Put back the filling cap (2), start the engine, let it run for 5 min-
utes and then stop it.
Check the level again and top up if necessary.
6 - Close the engine hood.
Use oil suitable for the ambient temperature (See “4.3 FUEL,
COOLANT AND LUBRICANTS”).
