Replacing the fuel and air filters on an echo trimmer The Facts

String trimmer out of whack? It's time to face the fix. Whether you are a legendary landscaper or a weekend weed whacker, provides the parts, procedures and facts you need to fearlessly fix what fails you.

If you want your powered equipment to last through multiple seasons, you must maintain it. The filter kit makes it easy to perform maintenance in two vital areas on your trimmer: the fuel and air systems.

The kit includes a new fuel filter, which prevents tiny particles in the fuel tank from reaching the carburetor; and a new air filter, which helps keep dirt and debris out of the intake components. Both are essential for engine performance and longevity. Both are simple to replace.

This article provides step-by-step instructions for installing a filter kit on an Echo SRM-225 trimmer.
