A3 - FUEL LEVEL
Keep the fuel tank full, to reduce as much as possible any condensation due to the
atmospheric conditions.
- Remove cap 1 (fig. A3).
- Fill the fuel tank with clean fuel (see: 3 - MAINTENANCE: LUBRICANTS AND FUEL), filtered
through a strainer or a clean, lint free cloth, through filler port 2 (fig. A3).
- Put the cap back 1 (fig. A3).
- Check visually that there is no leakage in the tank and pipes.
Never smoke or approach with a flame during filling operations or when the tank is open. Never refill
while I.C. engine is running.
The fuel tank is degassed via the filler plug. When changing it, always use an original part, with degassing
hole.
NOTE: A locking tank cap is available as an OPTION.
