CAUTION
We advise to drain and clean the tank periodically, at least once a year.
Please remember that re-used fuel must be ltered.
WARNING
The bilges of the engine room must always be kept clean, so that fuel or
oil leaks or penetrations from the engines or the generator can be easily
noticed. If leaks are noticed, it is necessary to stop the engines and to let
them cool and only afterward, if possible, repair the leak.
Finally clean the bilges.
ENVIRONMENT
It is forbidden to discharge bilge water mixed with oil or diesel fuel into the
sea, because this can cause of serious pollution. Periodically check the
level of possible oily waters inside the collection tanks under the engines;
should the level be next to overowing into the bilge, disconnect the mag-
neto-thermal switches of pumps of the bilge suction system, to prevent
accidental spilling, until the bilge is empty, in compliance with current leg-
islation for environmental protection. During the maintenance operation
in the engine room, it is compulsory to disconnect the magneto-thermals
of the bilge pumps suction system, avoiding in this way accidental spills.
MAINTENANCE
Check periodically the correct operation of the valves.
At least every three months check for the presence of leaks.
At least once every three months drain the tank.
At least once every two years carry out complete cleaning of the tank;
check anyway the draining according to the quality of fuel lled.
