String trimmer out of whack? It's time to face the fix. Whether you are a legendary landscaper or a weekend weed whacker, eReplacementParts.com provides the parts, procedures and facts you need to fearlessly fix what fails you.
Maintaining the air filter is one of the most important steps you can take to ensure that your trimmer continues to perform optimally for several years. The air filter keeps dirt and debris from clogging the trimmer's carburetor (and damaging the cylinder and piston). The filter should be frequently inspected for obstructions or defects, especially tears, which will allow dirt to enter the engine and cause significant damage in a very short time.
At a minimum, the air filter should be changed every year. This article will show you how to remove and install the air filter on an Echo trimmer (the model shown in this tutorial is the Echo SRM-225).
