Fuel tank

Clean fuel is essential for trouble-free running of the diesel engine.
The fuel tank holds 565 liters (149.3 US gal).
Carefully clean around the filler cap before removing it. Avoid spill-
ing fuel when filling as this attracts dirt. During the cold season
keep the tank full to prevent water condensing in the tank.

For fuel quality, See Recommended lubricants on page 177.
NOTE : Be careful not to damage fuel tank level gauge (A) by
being stained from thinner or oil.
Drain the sediment every 100 hours.
Remove drain valve (B) at the bottom of the tank and drain off any
sediment.

Changing fuel filter

When using the fuel to meet the legal requirements, change
the fuel filter every 1000 hours. For example of national and
international standards for marketed fuels: DIN EN970/
BS2869 A1 and A2/ASTM D975 1D and 2D. If in a situation to
use lower quality fuels, replacing cycle of the fuel filter may
be shortened.
Replacing cycle of the fuel filter should be less than half time
in the situation using the fuel that contains over 0.5% sulphur
content, over 0.01% water or sediment.
The filter is the disposable type, i.e. it cannot be cleaned, but
