Avoid using fuel that has been stored for more
than seven days as it causes malfunctioning and
decreases the useful life of the engine.
Fill the tank carefully not to spill the fuel.
Use common gasoline, diesel or biodiesel only
(do not use with additives).
Note the capacity of the fuel tank, and the quantity
and type of oil of the crankcase (see "Technical
Specifications").
