The quickest way to reload your Echo GT-225

The Echo GT-225 uses a fixed-line head that holds two lengths of .095-inch trimmer line. To reload it, you unscrew the spool cap on top of the head, pull out the old line, wind new line onto the spool in the correct direction, and screw the cap back down. The whole job takes about five minutes once you have the right line diameter.

The line head sits at the bottom of the shaft, just above where the cutting head spins. You do not need to remove the head from the trimmer itself — you work on it while it stays attached.

Key Takeaways

  • Echo GT-225 line heads use .095-inch diameter line, and using the wrong size will cause the line to slip or break.
  • The spool cap unscrews by hand; you do not need tools, but a rag helps grip it if it is stuck.
  • Line must wind onto the spool in a specific direction — clockwise when you face the cap — or it will not feed correctly.
  • Each of the two line slots holds roughly 15 to 20 feet of line, so cut two pieces of equal length before you start winding.

What you need before you start

Buy .095-inch trimmer line — this is the only diameter the GT-225 accepts. It comes in spools at any hardware store, home center, or online retailer. A 100-foot spool costs between $5 and $15 depending on the brand and will reload your trimmer many times over.

You do not need any tools. If the spool cap is tight, a dry cloth or old rag gives you grip. Have scissors or a utility knife ready to cut the line to length.

How to remove the old line

Stop the trimmer and let it cool for a minute. Locate the spool cap — it is the round plastic piece on top of the cutting head at the bottom of the shaft. Hold the head steady with one hand and turn the cap counterclockwise by hand until it comes free. Set it aside.

Pull out any remaining line from both slots in the spool. If line is wound tightly, you can pick at it with your fingernail or a small screwdriver to loosen the end, then pull it out. Wipe out any grass or debris from inside the spool with a dry cloth.

Measuring and cutting new line

Cut two pieces of .095-inch line. Each piece should be 15 to 20 feet long — if you are not sure, cut 18 feet per piece and trim it shorter if you have trouble fitting it. Having two equal lengths makes the trimmer head balanced and cuts more smoothly.

Lay the pieces on a flat surface so you can see them clearly. You will wind them one at a time, so keep them separate.

Winding line onto the spool

Look at the spool inside the head. You will see two slots or grooves running from the center outward — one on each side. Pick up the first piece of line and insert one end into the slot on the left side, pushing it into the center hole until about 6 inches sticks out the other side.

Hold the spool steady and wind the line clockwise — the direction a clock's hands move when you face the top of the head. Wind it tightly and neatly, keeping each wrap close to the one before it. Wind until you reach the outer edge of the spool, then tuck the end into the groove to hold it in place.

Repeat with the second piece of line in the right-hand slot, winding clockwise in the same direction. Both pieces should wind the same way, or the head will not feed line evenly.

Reinstalling the spool cap and testing

Check that both line ends are tucked into their grooves and will not slip out. Screw the spool cap back on by turning it clockwise by hand until it is snug. Do not force it — hand-tight is enough.

Start the trimmer and let it run for a few seconds at idle. The line should feed out slightly and the head should spin smoothly. If the line does not feed, stop the trimmer, remove the cap, and check that both pieces are wound in the same clockwise direction. If one is wound backward, the head will not feed correctly.

Frequently Asked Questions

What happens if I use the wrong line diameter?

Line thinner than .095 inch will slip on the spool and not feed. Line thicker than .095 inch will not fit in the slots or will jam. Always check the package — it should say .095 inch or 2.4 mm.

Can I wind the line counterclockwise instead?

No. The spool is designed to feed line only when it winds clockwise. If you wind it the other way, the line will not advance when the head spins, and you will have to reload it again.

How often do I need to replace the line?

It depends on how much you trim and what you cut. Hitting rocks, concrete, or thick brush wears line faster. Most people reload every few weeks of regular use. You will know it is time when the line gets too short to cut effectively or breaks during use.

Why is my line not feeding out?

The most common cause is line wound in the wrong direction. Stop the trimmer, remove the cap, and check that both pieces wind clockwise. The second cause is line that is too thin — verify the diameter on the package is .095 inch.

Can I use a different brand of line?

Yes. Any .095-inch trimmer line will work, regardless of brand. Some brands are thicker or thinner within that tolerance, so if one brand does not feed well, try another.
