Changing fuel filter
When using the fuel to meet the legal requirements, change
the fuel filter every 500 hours. For example of national and in-
ternational standards for marketed fuels: DIN EN970/BS2869
Al and A2IASTM D975 1 D and 2D. If in a situation to use lower
quality fuels, replacing cycle of the fuel filter may be short-
ened.
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
must be replaced.
Replace the fuel filter every 500 hours. If using fuel of lower
quality, replace the filter more often.
