CHANGING THE ENGINE OIL FILTER

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.
This operation must be carried out on every oil change.
Proceed as follows:
1 - Raise the engine hood (see "3.5.1 ENGINE HOOD").
2 - Lift the loader arm and secure it with the safety lock (see
"3.1.1 LOADER LOCKS").
3 - Drain the engine oil (see "4.8.6.g CHANGING THE ENGI-
NE OIL").
4 - Unscrew the used filter (1) with the special spanner provi-
ded and discard it.
5 - Clean the contact surface between the seal and the filter
support (2).
6 - Lubricate the seal of the new filter and screw thoroughly.
7 - Give a further half turn by hand.
8 - Fill the engine with new oil and complete the operations
as described in "4.8.6.g CHANGING THE ENGINE OIL".
Start the engine, make sure that there are no leakages and
that the oil pressure warning light goes out.
Close the engine hood.
IMPORTANT
Do not use the spanner to lock the filter, since this may
q
be damaged and cause oil leakages.
