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.
The air filter bracket provides an attachment point for the air cleaner lid on your trimmer. It also helps to secure the air cleaner case and the carburetor to the engine. While it is very easy to damage the bracket by overtightening the thumbscrew, it is also a very easy component to replace.
This article will show you how to remove and install the air filter bracket on an Echo trimmer (the model shown in this tutorial is the Echo SRM-225).
Let's get started.
REMOVING THE BRACKET [top] 1. Remove the air cleaner assembly.
Loosen the thumb screw.
Remove the air cleaner lid.
Remove the air filter.
2. Remove the air cleaner bracket.
Loosen the (2) bracket retaining screws.
Remove the air cleaner case from the engine.
Remove the bracket and screws from the air cleaner case.
INSTALLING THE NEW BRACKET [top] 3. Install the bracket and the air cleaner case.
Thread the (2) mounting screws through the mounting holes on the new bracket and the air cleaner case. The bracket should be flush against the interior of the case (on the same side as the choke valve).
Thread the screws (protruding from the air cleaner case) through the holes on the carburetor assembly.
Note that there are two small holes on the intake gasket (besides the main intake opening and the two mounting holes). These small holes need to align with the small hole on the insulator block.
Thread the screws through the mounting holes on the intake gasket and slide the gasket flush against the carburetor.
Install the intake assembly (bracket, air cleaner case, carburetor and intake gasket) onto the intake insulator block.
Secure the intake components (bracket, air cleaner case, carburetor and intake gasket) with the screws.
REASSEMBLING THE UNIT [top] 4. Reinstall the air filter.
Install the air filter into the air cleaner case.
5. Reinstall the air filter lid.
Install the air filter lid onto the air cleaner case.
Secure the air filter lid with the thumbscrew.
