NOTICE
Used fuel filters must be drained of all free-flowing fuel before they are discarded or recycled.

(a) Changing the Fuel Filter
NOTICE
When the element of the fuel filter is clogged, it can cause a decrease in engine output, engine
failure, engine failure indication or engine stop, so perform periodic inspections and maintenance.
The fuel filter has the function of removing filth or moisture in the fuel. The fuel filter has a significant
impact on the performance and service life of the engine and fuel economy, so use of the “Isuzu
genuine parts” is recommended.
Also, depending on the machine, an electromagnetic fuel pump which incorporates a fuel filter
may be equipped.
