4.7.9.a

CHANGING THE ENGINE OIL FILTER

DANGER
Soon after the machine has been stopped the engine oil is very hot and may cause burns; let the en-
gine 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 immediately remove any trace of oil from the floor.
Oils, filters, the coolant and the battery are considered special waste and must be collected and dis-
posed of according to the anti-pollution regulations in force.
This operation must be carried out every two oil changes.
Proceed as follows:
1 - Drain the engine oil (See "4.7.7.e CHANGING THE ENGINE
OIL").
2 - Unscrew the used filter (1) with the special spanner provided
and throw it away.
3 - Clean the contact surface between the seal and the filter sup-
port.
4 - Lubricate the seal of the new filter and screw thoroughly.
5 - Give another half turn by hand.
6 - Fill the engine with new oil and complete the operations as
described at point "4.7.7.e CHANGING THE ENGINE OIL").
Start the engine, make sure that there are no leakages and that
the oil pressure warning light goes out.
IMPORTANT
Do not use the spanner to lock the filter, since it may be
damaged and cause oil leakages.
