CHANGING THE ENGINE OIL

Soon after the machine has been stopped the engine oil
q
is very hot and may cause burns; let the engine cool
down until it reaches a temperature of 40-45ºC before
draining the oil.
The oil that may be spilled during the change makes the
q
ground slippery, therefore, use anti-slip shoes and im-
mediately remove any trace of oil from the floor.
Oils, filters, coolants and batteries are considered spe-
q
cial waste and must be collected and disposed of ac-
cording to the anti-pollution regulations in force.
NOTE
Drain the oil after positioning the flexible pipe outside the en-
q
gine compartment.
Change the engine oil at the same time as the engine oil filter
(see "4.8.6.h CHANGING THE ENGINE OIL FILTER").
This operation must be carried out with the machine parked on
firm and level ground and the step succession is the following:
1 - Detach the lower cover (1) after removing the fastening
screws (2). Use a 17 mm spanner.
2 - Extract the oil drain flexible pipe (3) from the lower ope-
ning.
3 - Raise the engine hood (see "3.5.1 ENGINE HOOD").
4 - Remove the drain plug (4) of the flexible pipe (3), gathe-
ring the used oil that flows out into a container with suita-
ble capacity. Use a 27 mm spanner.
While the oil flows out, remove the filling cap (5), so that
the oil can flow freely.
5 - Screw the plug (4) on to the flexible pipe and pour the pre-
scribed quantity of new oil, using the dipstick (6) to make
sure that the oil reaches the MAX. level.
6 - Put back the filling cap (5), start the engine, let it run for 5
minutes and then stop it.
Check the level again and top up if necessary.
7 - Close the lower cover (1).
8 - Close the engine hood.
Use oil suitable for the ambient temperature (see "4.3 FUEL,
COOLANT AND LUBRICANTS").
After the oil change and after removing any trace of oil,
q
put back the flexible pipe inside the engine compart-
ment.
