PUMP SUPPLY

IM

:

To avoid accidental fires owing to fuel leaks, which can be caused by an accident.

F

UNCTIONING

:

The shock-sensor lies in the engine compartment: it is mounted on the left-side shock-

absorber column.

During a shock, the ball of the sensor goes out of its slot, and thus achieves the breaking

of the electric circuit between the relay commanding the petrol-pump and the petrol-pump
itself.

     In order to resume the functioning of the shock-sensor it will suffice to press its top,
and thus replace the ball in its former position.
