What You’ll Need Before Starting

Before you begin the replacement process, gather these simple supplies to make the job faster and easier:

• Replacement trimmer line: Confirm the correct diameter for your Ego model first — most standard Ego weed eaters use 0.080” line for light-duty use, or 0.095” line for heavy-duty cutting of thick weeds and brush. If you don’t have your user manual handy, you can find the recommended line size by checking the label on the side of your weed eater’s shaft, or by looking up your model number on Ego’s official website.
• Work gloves: Protect your hands from sharp line edges and any debris in the trimmer head.
• Safety glasses: Trimmer line can snap unexpectedly, and grass debris can fly up during testing, so eye protection is a must.
• Flathead screwdriver (optional): Some older Ego models use a screw to hold the spool cover in place, so you may need this to remove it.
• Wire cutters or heavy-duty scissors: For cutting the new line to the correct length.
• Clean cloth and small brush: To clear away built-up grass, dirt, and sap from the trimmer head and spool before loading new line.

Having all these supplies on hand before you start will prevent interruptions and ensure you don’t have to scramble for tools halfway through the process.

Understanding Your Ego Weed Eater’s Trimmer Head Type

Ego manufactures three main types of trimmer heads for their weed eaters, and the process for replacing the line varies slightly depending on which one your model uses. To identify your head type, look at the bottom of the cutting head: bump feed heads have a small bump button on the bottom, fixed line heads have small line holes on the sides with no spool cover, and quick load heads have a small release button on the bottom that lets you pop the entire spool out. Identifying your head type first will ensure you follow the correct steps for a smooth replacement.

Bump Feed Heads

Bump feed heads are the most common type found on Ego weed eaters, and they’re designed for convenience. As the line wears down during use, you simply bump the bottom of the cutting head against the ground while the trimmer is running at full speed to release 4-6 inches of new line. These heads use a round internal spool that holds the wound trimmer line, and they’re ideal for most residential lawn care tasks like edging sidewalks and trimming grass around garden beds.

Fixed Line Heads

Fixed line heads don’t use a spool at all. Instead, you manually feed pre-cut lengths of trimmer line through holes on the sides of the head, and secure them in place with small clamps or knobs on the back of the head. These heads are more durable than bump feed models, and they’re less prone to jams, making them a great choice for heavy-duty use and cutting thick, woody vegetation like small saplings and dense overgrowth.

Quick Load Heads

Ego’s proprietary quick load heads are designed for ultra-fast line replacement with no winding required. The entire spool comes pre-loaded with line from the factory, and you simply pop the old spool out and snap a new one in when it’s time to replace the line. This design is perfect for beginners or users who want to minimize maintenance time, and it eliminates the risk of winding the line incorrectly.

Safety Precautions to Take First

Working on a weed eater is generally low-risk, but taking these basic safety steps will prevent accidents and injuries:

• Always remove the battery pack first: Never attempt to work on the trimmer head while the battery is installed, as accidental startup can cause serious injury. Make sure the battery is stored out of reach of children and pets while you work.
• Wear personal protective equipment (PPE): Safety glasses and work gloves are non-negotiable, even for a simple line replacement. Trimmer line can snap under tension, and debris can fly up from the head when you test it after replacement.
• Work on a stable, flat surface: Lay the weed eater down with the cutting head facing away from your body, so if it accidentally turns on, it won’t be pointed at you.
• Let a recently used head cool down: If you’ve just finished trimming, the cutting head can get hot enough to cause burns during extended use. Let it cool for 2-3 minutes before handling it.
• Clear debris from the head first: Use your brush and cloth to remove all built-up grass, weeds, dirt, and sap from the trimmer head and spool area before you start. This prevents dirt from getting into the feed mechanism and causing jams later.
• Keep bystanders away: Make sure children and pets are not in the work area while you’re handling the trimmer and sharp line.

Step-by-Step: How to Put String in Ego Weed Eater (Bump Feed Models)

Follow these steps for a smooth bump feed line replacement:

1. Remove the battery and prep the head: Take the battery out of the weed eater to avoid accidental power-on. Most Ego bump feed heads don’t require full detachment from the shaft, but if your model has a removable head, twist it counterclockwise to release it. If it’s fixed, you can work on it while it’s attached to the shaft.
2. Remove the old spool and remaining line: Locate the spool cover on the bottom of the cutting head — it’s usually held on by a small tab or a screw. Press the tab or unscrew the cover, then pull the old spool out. Pull off any remaining old line from the spool, and discard it.
3. Clean the spool and head housing: Use your clean cloth and brush to wipe away any grass, dirt, or debris from the spool, the spool housing, and the line feed slots. Built-up grime can cause the line to jam or feed improperly later, so this step is critical for long-term performance.
4. Wind the new trimmer line onto the spool: Take your new line (make sure it’s the correct diameter for your model). Cut a length of line that’s about 10-12 feet long (most spools hold this amount). Find the winding direction arrow on the spool — it’s almost always clockwise for Ego models. Start winding the line tightly around the spool, following the arrow direction, making sure the line is evenly spaced and doesn’t overlap. Leave about 6-8 inches of line sticking out from the spool, and tuck that end into the notch on the spool to hold it in place while you work.
5. Load the spool back into the head: Align the spool’s notches with the slots in the head housing, then push the spool in until it clicks into place. Make sure the line is fed through the correct exit hole on the side of the head, and that the loose end is pulled out about 4-6 inches from the head.
6. Reattach the spool cover: Snap or screw the spool cover back on securely, but don’t over-tighten the screw if your model has one — this can warp the cover and cause it to stick, making future replacements harder. Make sure it’s locked in place so it doesn’t come loose during use.
7. Test the feed: Reinsert the battery, turn on the weed eater, and bump the head lightly on a hard surface (like concrete) while the trimmer is running at full speed. You should see 4-6 inches of new line extend from both sides of the head. If it doesn’t feed, double-check that the line is wound in the correct direction and that the spool is seated properly.

Step-by-Step: How to Put String in Ego Weed Eater (Fixed Line Models)

Fixed line heads require a slightly different process, as they don’t use a wound spool. Follow these steps:

1. Prep the weed eater: Remove the battery pack, place the weed eater on a flat surface with the cutting head facing away from you. Clear away any built-up grass or debris from the line holes on the head.
2. Cut the new line to length: Most Ego fixed line models require 2 pieces of line, each 10-12 feet long (check your manual for exact length, as some models use longer or shorter pieces). Cut the line to size with your wire cutters, cutting the ends at a sharp 45-degree angle to make feeding through the head holes easier.
3. Feed the line through the head: Insert one end of the first line piece into the first line hole on the side of the head, pushing it all the way through until it comes out the opposite side. Pull both ends so that an equal length of line is sticking out of both holes (usually 6-8 inches per side). Repeat this process for the second line piece, feeding it through the second set of holes if your model has dual lines.
4. Secure the line: Some fixed line models have small knobs or clamps on the back of the head to tighten the line in place. If yours does, turn the knobs clockwise to secure the line so it doesn’t slip out during use.
5. Test the line: Reinsert the battery, turn on the trimmer, and let it run for a few seconds. Check that the line is straight, not tangled, and that both ends are the same length. If one side is longer, adjust it by pulling the longer end until both are equal.

Step-by-Step: How to Put String in Ego Weed Eater (Quick Load Models)

Quick load models are the fastest to replace, with no line winding required at all:

1. Remove the battery and old spool: Take the battery out of the weed eater. Locate the quick release button on the bottom of the cutting head — press it down, then pull the entire old spool assembly straight out. No winding required for removal!
2. Clean the head housing: Wipe away any debris from the slot where the spool sits, to make sure the new spool seats properly.
3. Insert the new pre-loaded spool: Align the notches on the new Ego quick load spool with the slots in the head housing, then push the spool in firmly until you hear a click, which means it’s locked in place. Only use Ego-approved quick load spools for your model, as third-party spools may not seat properly and can cause feed issues or damage to the head. The line will already be fed through the correct holes, so you don’t have to do any winding.
4. Test the feed: Reinsert the battery, turn on the trimmer, and bump the head on a hard surface to confirm the line extends properly. The whole process takes less than 30 seconds for most users.

Common Mistakes to Avoid When Replacing Trimmer Line

Avoid these common errors to prevent jams, poor performance, and unnecessary line breakage:

• Using the wrong line diameter: If you use line that’s too thick, it won’t fit through the feed holes or will jam the spool. If it’s too thin, it will break easily and won’t cut effectively. Always check your Ego model’s manual for the recommended line size.
• Winding the line in the wrong direction: For bump feed spools, winding counterclockwise will cause the line to tangle and not feed properly when you bump the head. Always follow the arrow on the spool.
• Overlapping the line on the spool: If you wind the line too tightly or overlap layers, it will get stuck on the spool and won’t feed out when needed. Wind it evenly, with each layer sitting next to the last, not on top.
• Leaving too little or too much line sticking out: If you leave less than 4 inches of line sticking out of the head, it won’t feed properly when you bump it. If you leave more than 6 inches, it can get tangled around the head during use. Aim for 4-6 inches of line extending from each side of the head after loading.
• Skipping the cleaning step: If you don’t clear old grass and debris from the head and spool before loading new line, the grime can cause jams, poor feed, and even damage to the spool mechanism over time.
• Trying to force the line into the head: If the line isn’t feeding through the holes easily, don’t force it — this can damage the feed slots or cause the line to fray. Make sure the end of the line is cut cleanly and at an angle, and that you’re using the correct line diameter for your model.

Tips for Extending Your Trimmer Line’s Lifespan

Follow these best practices to get the most out of your trimmer line and reduce how often you need to replace it:

• Avoid cutting against hard surfaces: Don’t bump the head on concrete, rocks, or curbs more than necessary to feed line — each bump wears down the line faster. Instead, adjust the line length manually if you can, or bump lightly on soft surfaces like grass when possible.
• Keep the line clean: After each use, wipe off any grass, sap, or dirt from the line and head. Built-up sap can make the line brittle and more likely to break.
• Store the weed eater properly: Keep it in a cool, dry place out of direct sunlight. Extreme heat can make the line dry out and become brittle, while cold can make it stiff and prone to breaking.
• Don’t overload the weed eater: Trying to cut thick, woody weeds or heavy brush with a standard trimmer line will cause it to break much faster. Use a heavier line size for tough jobs, or switch to a brush cutter attachment if you have heavy overgrowth.
• Wind the line evenly when replacing: A tightly, evenly wound spool feeds more smoothly and reduces friction, which makes the line last longer between replacements.
• Use line with UV protection: Some higher-quality trimmer lines are treated with UV inhibitors that prevent the line from drying out and becoming brittle in sunlight. This can extend the life of your line by 20-30% compared to standard untreated line.

How to Choose the Right Trimmer Line for Your Ego Weed Eater

Not all trimmer line is created equal, and choosing the right type for your use case will improve cutting performance and reduce how often you need to replace it. Below is a comparison of the most common line types compatible with Ego weed eaters:

No matter which line type you choose, always confirm it matches the diameter recommended for your specific Ego weed eater model. Using a line that’s too thick for your head can cause jams, while too thin a line will break constantly and reduce cutting efficiency. If you mostly cut light grass and weeds in a small residential lawn, standard round line is more than sufficient and will save you money. If you have a larger property or regularly cut thick overgrowth, opt for square or star-shaped line for better durability and cutting power.

Troubleshooting Common Issues After Line Replacement

If you run into problems after replacing your line, use these fixes to get your trimmer running smoothly again:

• Line won’t feed when I bump the head: First, check that the line is wound in the correct direction (for bump feed models). Next, make sure the spool is seated fully in the head housing — if it’s even slightly misaligned, the feed mechanism won’t engage. If you have a fixed line model, check that the line is pulled tight through the holes and not tangled inside the head.
• Line keeps breaking while I’m using the trimmer: This is usually caused by using the wrong line size, a dull line (new line should be sharp, but if it’s old stock it may be brittle), or cutting against hard surfaces. Also, if the line is overlapping on the spool, it can catch and break. Try replacing with a heavier line size if you’re cutting tough vegetation, and avoid bumping the head on concrete unnecessarily.
• Line is feeding out unevenly (one side is longer than the other): For bump feed models, this usually means the spool is not seated evenly in the housing. Remove the spool, re-seat it making sure it’s aligned properly, and test again. For fixed line models, simply pull the longer end of the line until both sides are equal length.
• Line is tangled inside the head: This almost always happens if you wound the line in the wrong direction, or if you overlapped layers when winding. Remove the spool, unwind all the line, and re-wind it following the arrow on the spool, making sure it’s evenly spaced with no overlaps.
• The line is vibrating excessively during use: This is usually caused by uneven line length (one side is longer than the other) or a misaligned spool. Adjust the line length so both sides are equal, and make sure the spool is seated fully in the head housing. If the problem persists, the spool may be damaged and need to be replaced.

Frequently Asked Questions

How often do I need to replace the string in my Ego weed eater?

This depends on how often you use the trimmer and what you’re cutting. For light residential use (cutting grass and small weeds a few times a month), you’ll need to replace the line every 2-3 months. For heavy use (large properties, cutting thick brush), you may need to replace it every 2-4 weeks. You’ll know it’s time to replace when the line is worn down to less than 2 inches, or when it breaks constantly even with light use.

Can I use third-party trimmer line in my Ego weed eater?

Yes, you can use third-party line as long as it matches the diameter recommended for your model (usually 0.080″ or 0.095″). Just make sure it’s high-quality nylon line, as cheap low-quality line will break easily and may not feed properly. Ego also sells their own branded line that’s specifically designed for their trimmer heads, which is a reliable option if you want to avoid compatibility issues.

Why does my Ego weed eater line keep jamming?

Jams are usually caused by one of four things: using the wrong line diameter, winding the line in the wrong direction, overlapping layers on the spool, or failing to clean debris out of the head before replacing the line. Follow the steps in this guide for your specific head type, and make sure you clean the head thoroughly before loading new line to avoid jams.

Can I wind more line onto the spool than the recommended length?

No, overfilling the spool will cause the line to overlap and tangle, which will lead to jams and poor feed. Stick to the recommended line length (usually 10-12 feet for most Ego bump feed spools) to ensure smooth operation.

Do I need to replace the entire spool, or can I just add more line?

For bump feed models, you can add more line to the existing spool if there’s still room, as long as the line is wound evenly and in the correct direction. For fixed line models, you can simply feed new line through the holes without replacing anything. For quick load models, you’ll need to replace the entire pre-loaded spool, as they’re designed to be swapped out entirely for convenience.

Can I sharpen my trimmer line to make it last longer?

No, you should never attempt to sharpen trimmer line. The line is designed to be flexible and dull enough to cut through grass without damaging plants or hard surfaces. Sharpening it will make it brittle and prone to breaking, and can also create sharp edges that can cause injury if the line snaps during use.

Conclusion

Replacing the string in your Ego weed eater is a simple, quick task that you can do at home in 5-10 minutes, no special tools or experience required. The key is to identify your trimmer head type first, follow the correct steps for your model, use the right line size, and take basic safety precautions. By following the tips in this guide, you’ll not only make the replacement process easier, but also extend the life of your trimmer line and keep your Ego weed eater running at peak performance for years to come.
