Use a wire hook to extract the fuel filter from inside the fuel tank. (Figure 

21). Inspect the fuel filter element. If it shows signs of contamination from 

debris, replace it with a genuine Shindaiwa replacement fuel filter element. 

Before reinstalling the filter, inspect the fuel line. If you discover damage or 

deterioration, the unit should be removed from service until it can be inspected 

by a Shindaiwa-trained service technician.

NOTE:

Federal EPA regulations require all model year 2012 and later gasoline powered engines produced for sale in the United States 

to be equipped with a special low permeation fuel supply hose between the carburetor and fuel tank. When servicing model year 

2012 and later equipment, only fuel supply hoses certified by EPA can be used to replace the original equipment supply hose. 

Fines up to $37,500 may be enforced for using an un-certified replacement part.)

CAUTION!

Make sure you do not pierce the fuel line with the end of the hooked wire. The 

line is delicate and can be damaged easily.
