The fuel filter, for this model string trimmer, needs to be replaced either after 25 hours of run time or each year. The filter ensures that debris does not enter the fuel system of the engine, thus maintaining proper performance of your string trimmer. Another reason you may need to replace the fuel filter is if you have not been using the proper fuel to oil ratio in the fuel mixture. This can cause the engine problems when starting. This fix can breathe new life into your string trimmer and have it running similar to the day you got it out of the box.
