18 MAINTENANCE
4. Bear it in mind that Biodiesel fuels have the
characteristics below. Referring to the servicing
intervals specified in
Operator's Manuals, be sure to maintain and clean up
the fuel system, replace the fuel rubber piping with
new ones and take other necessary measures. It is
advisable to replace the fuel filter with a new one after
half the specified replacement intervals.
(Compared with the use of mineral oil diesel fuels, the
filtration performance of fuel filters gets degraded
earlier than expected.)
A Biodiesel fuels easily induce the growth of
microorganisms and foul themselves. This may
get the fuel system corroded and the fuel filter
clogged.
A In cold weather, some problems may occur: the
clog of the fuel line or fuel system, starting failure,
and other unforeseen troubles.
A Biodiesel fuels easily soak up moisture, which
means that they may contain higher moisture
content than conventional diesel fuels.
5. Palm oil-based Biodiesel fuels are inferior in low-
temperature fluidity to soy-based and rapeseed-
based Biodiesel fuels. In cold season in particular, this
may clog the fuel filter.
6. If Biodiesel fuels are spilt on a coated surface, the
coating may get damaged. Immediately wipe the spill
off the surface.
To avoid personal injury or death:
A Do not stop the engine suddenly,
stop it after about 5 minutes of
unloaded idling.
A Work only after letting the engine and
the radiator cool off completely
(more than 30 minutes after it has
been stopped).
A Do not remove the radiator cap while
coolant is hot. When cool to the
touch, rotate cap to the first stop to
allow excess pressure to escape.
Then remove cap completely.
If overheats should occur, steam
may gush out from the radiator or the
reserve tank; Severe burns could
result.

1. Remove the radiator cap, after the engine has
completely cooled, and check to see that coolant
reaches the supply port.

2. If the radiator is provided with a reserve tank, check
the coolant level of the reserve tank. When it is
between the "FULL" and "LOW" marks, the coolant
will last for one day's work.
