How to String an ECHO Weed Eater: Step-by-Step

Replacing the string trimmer line on your Echo SRM‑225 doesn't have to be a chore. It's one of the simplest maintenance tasks you can do—and this KnowHowNow video shows you exactly how to do it fast, cleanly, and without frustration.

Here's the step-by-step process of how it's done, and what's most critical if you'd like to keep your Echo trimmer cutting like new.

Step 1: Remove the Bump Head Cap

Start by inverting the trimmer. Depending on the model, the bump head cap either snaps off under pressure from the sides or twists off. Inside, you'll find the spool and a spring—carefully remove both.

Step 2: Measure and Prepare the Line

Use .095" or .105" trimmer line. Cut a piece recommended by your echo trimmer parts manual (usually 20 feet), then fold it in half to find the midpoint. This loads both sides of the spool evenly.

Put each end of the line through the correct eyelets and begin winding in the arrow's direction—usually clockwise.

Step 3: Load and Wind Properly

Be sure to wind the line evenly and tightly. This will prevent jamming and allow for smoother feeding when utilizing the bump feed system. Leave approximately 6 inches of line protruding from each side upon completion.

Step 4: Reassemble the Spool

Replace the spool and spring into the head. Align holes in the spool with eyelets in the housing so the line feeds freely. Snap the bump cap back on until it clicks or locks into place.

Final Test: Bump and Go

Turn on the trimmer and hit the head on the floor. If it feeds the line correctly, you succeeded. If not, open it again and search for a tangled or crossed line.

This is one of those quick wins: no tools, no frustration—just a few minutes of prep for smooth cutting all season.

How to Start an ECHO Weed Eater Properly

Many customers ask how to start an ECHO weed eater—especially if they have no experience with a 2-cycle engine. Use this simple procedure:

1. Move the switch to the "on" position.
2. Prime the bulb 5–6 times, and you will see fuel.
3. Set the choke to the closed position.
4. Pull the starter rope until the engine comes up for a brief moment.
5. Move the choke to the run position and pull again to fully start.

What Size Eater String for ECHO?

The string size depends on your model, but most ECHO weed eaters use either 0.080" or 0.095" line. For lighter, residential use, stick to 0.080". For heavier trimming or commercial jobs, 0.095" provides more strength and durability without slowing the tool down.

Using the correct line size helps avoid performance issues like the trimmer bogging down when you give it gas, a common complaint linked to incorrect string type or engine strain.

Quick Troubleshooting When You're There

If your ECHO trimmer won't work properly, it could be related to simple repairs:

• Why won't my ECHO weed eater begin? Nine out of ten times, it's because it contains stale fuel, a plugged air filter, or a filthy spark plug.
• ECHO weed eater bogging when I open the throttle? That generally means that the carburetor or fuel lines need to be cleaned.
• New to this? Here's how to start an ECHO weed cutter: prime the bulb, put the choke, pull to fire, then set the choke to run and pull again.

You can fix these issues easily, remaining on course.

How Much Is an ECHO Weed Cutter

Prices are model-dependent, but if you're considering how much an ECHO weed eater costs, their entry-level models begin at about $160, and stronger, commercial-style models will be in the $300 or more range. Considering the speed and convenience you receive, most users feel that ECHO is a good value.
