YANMAR 209 coo: 000 ares

85 diesel fuels must meet certain specifications

‘The biodiesel fuels must meet he minimum

specications forthe country in which they are

‘wth the American Standard ASTM 0.6751

Biodiesel should be purchased only trom
recognized and authorized diesel fel supp.

Precautions and concerns regarding the use of

bio-fuels:

+ Biodiesel fuels have a higher content of
meihykesters, which may deteriorate certain
meta, rubber and plastic components ofthe fuel
system. The customer andior boat builder are
responsible to very the usage of biodiesel
‘compatible components onthe vesso uel supply
and tur systems.

+ Froo watorin biodiesel may result in plugging of
{el titers and increased bacterial growth,

+ High viscosity at low temperatures may result in
{uo delivery problems, injection pump seizures,
and poor injection nozzle spray atomization.

+ Biodiosel may have adverse elacis on some
lastomers (Seal materials) and may result in tuo
leakage and dation a ho engine lubvcating ol

+ Even biodiesel uels that comply with a suitable
standard as delivered, ll require addtional caro
“and attention to maintain the qualiy ofthe fue in
the equipment or other ol tanks. Its important
tomaintain a supply o clean, fresh fuel. Regular
ttushing ofthe fuel system, andlor fuel storage
containers, may be necessary.

+ The use of biodiesel als that d not compl with
the standards as agreod to by the diesel engine
manufacturer and the diese uel injection
‘equipment manulacturer, or biodiesel lues that
have degraded as per the precautions and
concerns above, may affect the warranty
