3.3.4 STOPPING THE ENGINE

IMPORTANT

q

The sudden stop of the engine while it is running shortens its life.

q

Do not stop the engine suddenly, except in case of emergency. It is likewise recommended not to stop 
the engine suddenly if it has been running for a long period and is still hot; in this case, let the engine 
run at low idling speed for about 5 minutes, in order to allow it to cool down gradually before stopping it.

1.

Run  the  engine  at  low  idling  speed  for  about  5  minutes,  in 
order to allow it to cool down gradually.

2.

Turn the ignition key (1) to position OFF to stop the engine.

3.

Remove the key (1).
