All operations should be carried
out taking great care to avoid injury to persons.The engine compartment contains numerous
moving parts, components at high temperatures and electrical wiring
with voltage. Follow these precautions scrupulously when carrying
out operations in the engine compartment:
- turn off the engine and wait for it to cool down
- do not smoke
- no naked flames
- make sure that there is a fire extinguisher in the vicinity.
For some procedures, the use of special
tools is indicated. The use of these tools is vital in order to
work safely.Follow the safety instructions in force
for workshop procedures. Where necessary, the Manual contains specific warnings
to prevent the risk of dangerous situations.When using chemicals, closely follow the
safety instructions given on the safety sheet which the supplier
must give to the user.The electronic ignition system generates
voltages of 20,000 V and higher which could be very dangerous to people,
especially if they suffer from a heart condition. Great care should
be taken when working on this system or near its components.
All the operations should be
carried out taking great care not to damage the components.Before any operation on the electrical equipment
components, including the battery, make sure that the ignition is in
the OFF position.In order to release parts which are sticking,
tap gently with an aluminium or lead hammer if iron materials are involved:
use a wooden or resin hammer for light alloy parts. use a wooden
or resin hammer for light alloy parts.When dismantling, check that the components
have reference marks.During refitting, lubricate the parts as
necessary to prevent seizure during the initial period of operation.
When refitting, it is vital to follow the recommended tightening
torques and adjustment data.During each refitting, replace the gaskets,
oil seals, spring washers, safety plates, self-locking nuts, pre-treated
bolts and all components which have deteriorated.Protect adequately with adhesive tape or
clean rags those parts of the engine which, remaining uncovered
following dismantling, offer entry passages to dust or foreign bodies.The replacement of removed assemblies or
components should be carried out using genuine spare parts only:
this is the only way that the interchangeability and perfect operation
of the various components can be guaranteed.
