After using the vehicle, the exhaust system becomes
extremely hot due to heat from the exhaust gas
To prevent fire or burn:
Park the vehicle properly so that pedestrian or children
cannot reach.
Do not park the vehicle in the vicinity of flammables.
Make sure the exhaust system has cooled off before
performing any maintenance.
Never turn off the main power switch while riding the
vehicle. Otherwise a great amount of non-burnt gas
mixture will enter into muffler and combust there,
damaging and burning the Catalytic Converter.
Use only unleaded gasoline; leaded gasoline can
result in aging and failure of Catalytic Converter.
