Inspect the filter element for signs of
contamination from debris. A contami-
nated fuel filter should be replaced with
a new Shindaiwa replacement element.
Before reinstalling the filter, inspect the
condition of the fuel line. If you note
damage or deterioration, the blower
should be removed from service until
it can be inspected by a Shindaiwa-
trained service technician.

der fins and crankcase.
