2.3 REFUELLING
The tank cap is located underneath the initial part of the
seat. To refuel, remove the initial part of the seat “1”, then
unscrew the cap “2” counter-clockwise.
To remove the initial part of the seat, insert your fingers into
the opening “A” and lift it towards the rear of the vehicle.
When reassembling, make sure that the grommets “3” are
correctly engaged in the relevant supports “4”.
Do not smoke or use naked flames when refuelling.
Avoid using electrical devices or any source that
can trigger sparks or ignition. Failure to comply
with these rules could result in a danger of fire or
explosion, causing serious damage to property and/
or persons.
Do not add additives or other substances to the fuel
during refuelling.
Avoid fuel leakage during refuelling. If you use a
funnel, make sure that it is perfectly clean.
It is recommended to use the type of fuel indicated
in the technical specifications of this manual. Do
not use different fuels, they could damage the fuel
system and compromise the operation of the engine.
Make sure that the tank cap is closed.
