damaged easily.

filter from inside the fuel tank. Inspect

the fuel filter element for signs of

contamination. Replace it with a new

one if required. Before reinstalling

the filter, inspect the fuel line. If you

find damage or deterioration, remove

the unit from service until it can be

inspected by a Shindaiwa-trained
