. If the connection process does not work smoothly,
disconnect and re-connect nozzle as indicated under 'Operation Instructions'.

release to the atmosphere occurs, immediately stop fuelling
. If the leakage continues, push

:
Disconnect and re-connect nozzle as indicated under 'Operation Instructions'.
If it continues to not work properly or you have any doubts or questions, please contact the
