The filter sits on the end of the fuel hose in the tank of the Good Luck chainsaw and traps dirt that could get into the carburetor. Country of origin: China.
Replace it when it is dirty: the saw stalls under load or loses power. As a preventive measure, it is replaced once a season so as not to clog the carburetor jets.
When replacing, clean the seat of dirt, oil and sawdust and inspect the neighboring parts: a worn unit often drags the others with it.
