To string an EGO trimmer, remove the battery, confirm the correct line size, and reload the head according to its loading marks. Many EGO string trimmers use 0.095-inch line, but the head design determines whether you need a pre-cut coil or a reload spool.
The basic process is simple when you identify the head first. Some EGO heads accept pre-cut lengths, while Rapid Reload heads let you feed line through the head and wind it with a knob.
What should you do before replacing EGO trimmer line?
Turn the trimmer off and remove the battery before touching the head. Place the tool on a stable surface, wear eye protection, and clear away worn line and grass from the guard.
Check the line diameter printed on the head or specified in the manual. EGO products in this guide use 0.095-inch line, but that does not mean every EGO head accepts the same loading method.
Inspect the head for cracks, loose parts, or a bent eyelet. If the head is damaged, replacing the line may not solve feeding problems.

How do you choose the right EGO string trimmer replacement line?
Match the line diameter, length, and head requirements before loading it. A 0.095-inch line is common on EGO 15-inch trimmers, but always follow the markings on your specific head.
Line shape also affects how you work. Twisted line is designed for professional results and a clean, level cut, while dual-color line makes the center easier to find during loading.
The EGO Power+ Twisted String Trimmer Lines come as 5 pre-cut pieces, with each piece measuring 14 ft and 0.095 inches in diameter. They are compatible with EGO POWER+ string trimmers and the STA1500 15-inch Multi-Head attachment.

For another option, the EGO POWER+ 095” Dual Color Pre-Cut Trimmer Line includes 5 pre-cut coils of 0.095-inch professional-grade line, with each coil measuring 14 ft. Its dual-color design helps you find the center during loading.

How do you string an EGO trimmer with pre-cut line?
Feed the center of the pre-cut line through the head, then wind both sides evenly in the marked direction. The exact holes and turning direction vary by head, so use the arrows and channels molded into your EGO head.
Follow these steps:
- Remove the battery and clean grass from the head.
- Find the line-loading holes or eyelets on opposite sides of the head.
- Fold the pre-cut line in half to locate its center.
- Push the center into the head's center slot or loading opening.
- Pull both ends through evenly.
- Turn the reload knob or head in the direction marked on the housing.
- Stop when both ends extend evenly and the line sits inside the guides.
- Trim or adjust the ends only as the manual directs.
Don't force line through a blocked eyelet. Clear debris with the tool disconnected, and stop if the line bunches inside the head.
Keep the two ends close in length. Uneven ends can make the head vibrate or cut less evenly, while excessive line can contact the guard or overload the head.
How do you use a Rapid Reload EGO head?
A Rapid Reload head lets you feed line through the head and turn the reload knob to wind it. This method avoids removing the head for a routine line change.
The EGO Power+ MST1501 Multi-Head Combo Kit includes a 15-inch String Trimmer Attachment with a Rapid Reload head pre-wound with 0.095-inch dual-twist line. The kit also includes the PH1400 Power Head, a 56V 5.0Ah battery, and a standard charger.

See it on AmazonTo reload a compatible Rapid Reload head:
- Remove the battery from the power head.
- Pull out the remaining line, if the head allows removal from the eyelets.
- Align the head's loading marks.
- Feed the correct line length through both sides of the head.
- Turn the reload knob in the marked direction.
- Wind until the line ends are even and the head is filled without crowding.
- Check that the line moves freely through both eyelets.
The MST1501 has a 15-inch cutting width and includes a 56V 5.0Ah ARC Lithium battery with up to 45 minutes of runtime on a single charge. Its trimmer attachment works with EGO POWER+ Multi-Head System power heads PH1400 and PH1420, plus the EP7500 extension pole.
The kit suits someone who needs a complete EGO Multi-Head setup rather than line alone. It is more equipment than you need if your current power head and battery already work.
How do you know the line is loaded correctly?
The line should be evenly wound, move through both eyelets, and extend to similar lengths on each side. The head should turn without rubbing, wobbling, or catching loose line.
Hold the head still and inspect the winding before reinstalling the battery. Line that crosses over itself or sits outside the channel can jam during trimming.
Keep the line inside the head's guide path. Don't pack extra line into the cavity just because space remains, since the head is designed for a specific line diameter and loading amount.
Test the trimmer in an open area after reconnecting the battery. Start at low contact with grass and stop immediately if you hear unusual vibration or see the line strike the guard.
What mistakes cause EGO trimmer line problems?
The most common mistakes are using the wrong diameter, winding in the wrong direction, and loading uneven ends. Each can cause poor feeding, vibration, or repeated breakage.
Avoid these problems:
- Don't guess the line size from its color.
- Don't use line that is too thick for the head.
- Don't wind against the arrow marked on the head.
- Don't leave one end much longer than the other.
- Don't push line through grass, rocks, edging, or concrete.
- Don't run the trimmer with a cracked head or damaged eyelet.
- Don't work on the head while the battery is installed.
If line breaks quickly, inspect the surfaces you are trimming around. Fences, curbs, stones, and walls can wear line faster than open grass.
When should you replace the whole trimmer head?
Replace the head when it is cracked, badly worn, or no longer feeds line after correct loading. A new line cannot repair damaged eyelets, broken guides, or a head that will not hold the line.

Also check the battery and power head when the trimmer will not start. Our guide to the best ego string trimmer battery replacement covers the next step when the battery no longer supports your work.
How often should you replace EGO trimmer line?
Replace line whenever it becomes too short, brittle, uneven, or difficult to feed. The timing depends on the amount of trimming and the surfaces around your lawn.
Grass-only work usually uses less line than edging beside concrete or stone. Inspect the head before each session and keep spare pre-cut pieces in a dry place.

What is the simplest way to string an EGO trimmer?
Choose the correct 0.095-inch line when your head requires it, use a pre-cut coil, and follow the head's arrows while keeping both ends even. The Twisted String Trimmer Lines suit standard pre-cut replacement, while the Dual Color option makes the center easier to identify.
Choose the MST1501 combo if you need a complete 15-inch EGO Multi-Head setup with its power head, battery, and charger. If you already own the tool, line alone is usually the more direct fix.
Finally, inspect the head before every reload and remove the battery before working on it. That simple routine helps you avoid loading errors and catches damaged parts before the next trimming session.
Frequently asked questions
What size line does an EGO string trimmer use?
Many EGO string trimmers use 0.095-inch line, but the correct size depends on the head and model. Check the markings on your trimmer head or the owner's manual before loading line.
Using the wrong diameter can prevent proper feeding or damage the head.
How do you load a Rapid Reload EGO trimmer head?
Switch off the trimmer and remove its battery first. Align the line with the head's loading marks, feed the correct length through the head, then turn the reload knob in the marked direction until the line is evenly wound.
Follow the model manual if its steps differ.
Can you use pre-cut line in an EGO trimmer?
Yes, pre-cut line can simplify replacement when its diameter and length match the trimmer head. EGO offers 0.095-inch pre-cut coils in 14 ft lengths, including twisted and dual-color options.

Why does my EGO trimmer line keep breaking?
