All the operations must be carried out with the utmost attention and care to avoid damaging the components.

Before any interventions on electrical components, including battery disconnection, make sure that the ignition is off ('STOP' position).

In order to release parts which are sticking, apply gentle blows using 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.

During dismantling, check that parts which have to be marked carry reference marks.

When refitting, lubricate the parts, where necessary, to prevent sticking or seizing during the initial operating period. During refitting, it is essential to observe the 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.
