Why You Should Learn to String Your Husqvarna Weed Eater

If you’ve ever been in the middle of trimming your lawn only to have the line run out, you know how frustrating it can be to stop what you’re doing to run to the hardware store for a replacement trimmer head. Learning How to String a Husqvarna Weed Eater? eliminates that hassle entirely, and comes with a host of other benefits too.

First, it saves you significant money over time. A replacement Husqvarna trimmer head costs between $25 and $50, while a roll of compatible trimmer line costs just $3 to $10, and can be used for multiple restringing jobs. Over the course of a year, that adds up to hundreds of dollars in savings, especially if you have a large property that requires frequent trimming or use your weed eater for commercial landscaping work.

Second, it is far more convenient than relying on replacement heads. Instead of making a trip to the store or waiting for a repair appointment, you can restring your weed eater on the spot in minutes, getting back to your work right away. This is especially useful if you notice the line is worn down mid-job, and don’t have time to run to the store before finishing your yard work.

Third, proper restringing extends the overall life of your tool. A worn-out or improperly installed line puts extra strain on the weed eater’s engine, leading to faster wear and tear on internal components like the crankshaft and bearings. By restringing correctly and replacing line before it is completely worn down, you keep your tool running smoothly for years to come, protecting your initial investment.

Finally, restringing lets you customize your line for different jobs. Thicker, serrated line works best for cutting thick brush and overgrown weeds, while thinner round line is ideal for maintaining neat edges on grass and mulch beds. Being able to swap out line types on demand means you always have the right tool for the job, without having to buy multiple weed eaters for different tasks.

Tools and Materials You’ll Need

One of the best parts of restringing a Husqvarna weed eater is that you don’t need any specialized, expensive tools to get the job done. Most of the items you’ll need are already lying around your garage. Here’s a full list of what to gather before you start:

• New Husqvarna-compatible trimmer line (check your owner’s manual for the recommended diameter; .065″ and .080″ are most common for residential models, while .095″ and larger are for commercial use)
• Wire cutters or heavy-duty scissors (for cutting line cleanly)
• Work gloves (to protect your hands from sharp line edges)
• Clean rag (for wiping away dirt and debris from the trimmer head)
• Small flathead screwdriver or needle-nose pliers (for removing retaining rings or screws on the trimmer head)
• Safety glasses (to protect your eyes from flying line fragments)
• Optional: Trim line lubricant (to reduce friction and extend line life, especially for bump and automatic feed heads)

If you don’t have wire cutters, sharp heavy-duty scissors will work just fine, as long as they can cut through the trimmer line without fraying. Avoid using dull tools, as they will leave ragged edges on the line that can cause jams and breakage.

Safety Precautions Before You Start

Restringing a weed eater is a low-risk task, but taking a few basic safety precautions will prevent injuries and damage to your tool. Follow these steps before you touch the trimmer head:

1. Disconnect power to the trimmer: For gas-powered models, pull the spark plug wire off the spark plug to prevent the engine from accidentally starting. For cordless/battery-powered models, remove the battery pack entirely. Never restring a weed eater while it is connected to a power source, even if it is turned off.
2. Wear protective gear: Put on safety glasses and work gloves before you start. Trimmer line is sharp and can snap unexpectedly, causing serious eye injuries or cuts to your hands. Wear closed-toe shoes as well, to protect your feet if the line flies off the head.
3. Work in a safe area: Restring your weed eater on a flat, stable surface, away from children and pets. If you are using a gas model, work in a well-ventilated area away from open flames or sparks.
4. Let the trimmer cool down: If you just used the weed eater, wait 10–15 minutes for the head and engine to cool before handling it. The trimmer head can get very hot during use, and touching it can cause burns.
5. Avoid loose clothing and long hair: Tie back long hair, and avoid wearing loose sleeves or jewelry that could get caught in the trimmer head or line while you work.

Understanding Your Husqvarna Weed Eater’s Trimmer Head Type

Husqvarna manufactures three main types of trimmer heads for their weed eaters, and the restringing process varies slightly depending on which type you have. Identifying your head type before you start will make the process much smoother. Below is a comparison of the three most common types to help you tell them apart:

To identify your head type, look for these key features:

• Bump feed: Has a small button or protruding tab on the bottom of the head, used to advance line when tapped on the ground.
• Fixed line: Has no moving parts or buttons on the bottom, with small slots on the sides of the head to hold pre-cut line in place.
• Automatic feed: Has a small sensor or button on the bottom of the head, and no need to tap to advance line.

If you are still unsure, check your Husqvarna owner’s manual, which will list your model’s trimmer head type and recommended line specifications.

Step 1: Prepare Your Weed Eater for Restringing

Proper preparation will make the restringing process faster and reduce the risk of mistakes or injury. Follow these steps to get your weed eater ready:

1. Lay the weed eater on a flat, stable surface, with the engine or motor side facing up. This keeps the trimmer head from rolling while you work.
2. Double-check that power is disconnected: pull the spark plug wire off the spark plug for gas models, or remove the battery pack for cordless models. Set the power source aside in a safe place.
3. Put on your safety glasses and work gloves before handling the trimmer head.
4. Use your clean rag to wipe away any dirt, grass clippings, or debris from the outside of the trimmer head. This prevents dirt from falling inside the head when you remove the bottom plate, which can cause jams or damage to the feeding mechanism.
5. If you have a bump or automatic feed head, extend the line fully by tapping the head on the ground (for bump feed) or running the trimmer for a few seconds (for auto feed) before you start. This ensures all the line is unwound from the spool, so you don’t have loose line tangling while you remove the old line.

Step 2: Remove the Old Trimmer Line

Removing the old line is the first step in the restringing process, and it only takes a minute or two. Here’s how to do it correctly:

1. Locate the retaining mechanism on the bottom of the trimmer head. Most Husqvarna models use either a retaining ring that snaps into place around the edge of the head, or a small retaining screw that holds the bottom plate on.
2. If your head has a retaining ring, use your flathead screwdriver or needle-nose pliers to gently pry the ring off. Work your way around the edge of the ring to avoid bending it, as a bent ring will not snap back into place properly. If the ring is stuck, you can tap it gently with the handle of your screwdriver to loosen it.
3. If your head has a retaining screw, turn it counterclockwise with your screwdriver until it is loose, then pull the bottom plate straight off the head. Do not twist the bottom plate, as this can damage the threads on the screw or the head itself.
4. Pull the entire spool out of the head, along with any remaining old line. If the line is stuck in the spool, use your wire cutters to snip it into small pieces, then pull it out.
5. Use your rag to wipe away any dirt, grass clippings, or old line fragments from inside the trimmer head and the spool. Check the spool for cracks, warping, or excessive wear – if the spool is damaged, you will need to replace the entire trimmer head, as a damaged spool will not hold line correctly.
6. Set the old line aside for disposal, and set the clean spool and head aside for the restringing step.

Step 3: Measure and Cut the New Trimmer Line

Cutting your line to the correct length is critical to avoiding jams and feeding issues later. The required length varies by trimmer head type and model, so always check your owner’s manual for the exact specification for your weed eater. As a general rule:

• For bump and automatic feed heads: You will need two equal lengths of line, each 10–15 feet long for residential models, or 15–20 feet long for commercial models with larger heads.
• For fixed line heads: You will need two pre-cut lengths of line, usually 8–12 feet long, depending on your head size.

To cut the line:

1. Measure out twice the total length of line you need (for example, if you need two 12-foot lengths, measure out 24 feet of line total).
2. Cut the measured line in half with your wire cutters or heavy-duty scissors, so you have two equal lengths. Make clean, straight cuts to avoid frayed edges – frayed line will catch on the spool and cause jams.
3. Double-check that the diameter of the line matches the rating for your trimmer head. Using line that is too thick can damage the head and engine, while line that is too thin will break frequently and not cut efficiently. The recommended line size is printed on the side of the trimmer head and listed in your owner’s manual.

Pro Tip: If you frequently cut weeds with thick, woody stems, opt for serrated or square trimmer line instead of round line. The serrated edges cut through tough material much more efficiently, reducing the strain on your trimmer’s engine and extending line life.

Step 4: Restring Bump Feed Trimmer Heads

Bump feed heads are the most common type on residential Husqvarna weed eaters, and restringing them is straightforward once you get the hang of the winding direction. Follow these steps:

1. Take one length of cut line, and insert one end into the small hole in the center of the spool. Push the line all the way through the spool until it comes out the opposite side.
2. Leave 2–3 inches of line sticking out of the hole on one side of the spool, then begin winding the line tightly around the spool in the direction of the arrow printed on the spool. Almost all Husqvarna bump feed spools have a winding direction arrow – winding the line backwards will prevent it from feeding correctly when you tap the head. Wind 5–7 turns for light residential use, or 8–10 turns if you will be cutting thicker weeds and brush.
3. Once you have wound the line, leave 2–3 inches of the other end of the line sticking out of the opposite hole in the spool. Do not cut the excess line yet.
4. Repeat the process with the second length of line: insert one end into the center hole, leave 2–3 inches sticking out, wind in the same direction as the first piece, and leave 2–3 inches sticking out the other side.
5. Align the two loose ends of line with the small slots on the bottom plate of the trimmer head. Make sure the line is not tangled, and that the ends are long enough to reach the edge of the head once the plate is installed.
6. Push the spool into the trimmer head, making sure the loose ends of line stay seated in the slots on the bottom plate. Press down firmly until the spool clicks into place.
7. Snap the retaining ring back into place around the edge of the head, or screw the retaining screw back in clockwise until it is tight. You should hear a click when the ring is fully seated.
8. Pull both loose ends of line to make sure they are seated correctly, then cut off any excess line so it is even with the edge of the head.
9. Reconnect the spark plug wire or battery, then test the feed by tapping the head lightly on the ground while the trimmer is running. The line should advance 2–3 inches with each tap. If it does not, double-check that you wound the line in the correct direction and that the retaining ring is fully snapped on.

Step 5: Restring Fixed Line Trimmer Heads

Fixed line heads are even simpler to restring than bump feed heads, as they have no feeding mechanism or winding requirements. They are ideal for heavy-duty use, as there are no moving parts to wear out. Here’s how to restring them:

1. Take one pre-cut length of line, and insert one end into the slot on one side of the trimmer head. Push the line all the way through the head until it comes out the opposite slot.
2. Pull both ends of the line tight, so it is taut across the head. If your head has small clips or latches to hold the line in place, snap them over the line to secure it. If there are no clips, make sure the line is wedged tightly in the slots so it does not pull out during use.
3. Repeat the process with the second length of line, inserting it into the remaining slots on the head. Most fixed line heads have four slots total, two on each side, to hold two pieces of line.
4. Cut off any excess line with your wire cutters, so both ends are even with the edge of the head. Uneven line will cause the trimmer to vibrate excessively and cut poorly.
5. Reconnect power to the trimmer and test it by running it at full speed. The line should be taut and not wobble. If it is loose, double-check that the line is seated tightly in the slots.

Fixed line heads do not require any winding, so there is no risk of winding the line backwards. They are a great option for beginners who want a low-maintenance trimmer head.

Step 6: Restring Automatic Feed Trimmer Heads

Automatic feed heads are designed for professional and heavy residential use, and restringing them is very similar to restringing bump feed heads, with one small extra step to calibrate the sensor. Follow these steps:

1. Take one length of cut line, insert one end into the center hole of the spool, and push it through until it comes out the opposite side.
2. Leave 2–3 inches of line sticking out of one side of the spool, then wind the line tightly around the spool in the direction of the arrow printed on the spool. Wind 5–7 turns for most residential use, or 8–10 turns for heavy commercial use.
3. Leave 2–3 inches of the other end of the line sticking out of the opposite hole in the spool.
4. Repeat the process with the second length of line, winding it in the same direction as the first piece.
5. Align the loose ends of line with the slots on the bottom plate of the head, then push the spool into the head until it clicks into place.
6. Snap the retaining ring on or screw the retaining screw back in tightly.
7. Pull both loose ends of line to seat them, then cut off any excess line so it is even with the edge of the head.
8. Reconnect power to the trimmer, then test the automatic feed by holding the trimmer against a thick patch of grass or weeds. The line should advance automatically without you tapping the head. If it does not advance, check that the sensor on the bottom of the head is not covered in dirt or debris – wipe it clean with your rag and test again. If it still does not work, consult your owner’s manual for calibration instructions, as some models require you to reset the sensor after restringing.

Tips for Extending Trimmer Line Life

With proper care, your trimmer line can last for weeks or even months, depending on how often you use your weed eater. Follow these tips to get the most out of your line and reduce how often you need to restring:

• Always use the correct line diameter for your trimmer head and the job you are doing. Thinner line is better for light grass trimming, while thicker, serrated line is better for cutting thick brush. Never use line larger than the recommended size for your head, as it can damage the engine and feeding mechanism.
• Avoid tapping your bump feed head on concrete, rocks, or other hard surfaces while trimming. Tapping on hard surfaces wears down the line faster and can damage the feeding mechanism inside the head. Tap the head on soft ground or grass only.
• Wipe the line down with a dry rag after each use if you are cutting wet grass or weeds with sticky sap. Sap and moisture can corrode the line over time, making it brittle and prone to breaking.
• Store extra trimmer line in a cool, dry place, out of direct sunlight. Prolonged exposure to sunlight and heat will make the line brittle and weak, causing it to break more often.
• Don’t let the line run all the way down to the spool before restringing. If the line wears down to less than 2 inches, the engine has to work harder to cut, which can cause damage to the trimmer and make the line break more frequently.
• If you notice the line breaking more often than usual, check the area you are trimming for sharp rocks, sticks, or other objects that could be cutting the line. Clear debris from your trimming area before you start to reduce line wear.

Troubleshooting Common Restringing Issues

Even if you follow all the steps correctly, you may run into small issues when restringing your weed eater. Here are fixes for the most common problems:

• Line won’t advance on bump or automatic feed heads: This is almost always caused by winding the line in the wrong direction, or the line being tangled inside the head. Remove the spool and check that the line is wound tightly in the direction of the arrow on the spool, with no tangles. Also make sure the retaining ring is fully snapped on, as a loose ring can prevent the feeding mechanism from working.
• Line keeps breaking while trimming: First, check that you are using the correct line diameter for your head. If the line is the right size, check that the head is properly secured – a loose head can cause the line to vibrate and break. Also, make sure you are not hitting rocks or concrete while trimming, as this will snap even high-quality line.
• Line wobbles or is uneven after restringing: This is usually caused by cutting the two ends of the line to different lengths, or not winding the line tightly around the spool. Remove the spool, rewind the line tightly, and cut both ends to the exact same length. Also make sure the spool is seated fully in the head, with no gaps.
• Line jams inside the head: Overfilling the spool with too much line is the most common cause of jams. Remove the spool and unwind 2–3 turns of line, then reinstall it. Also check for tangles inside the head, and make sure the line is not twisted when you install the bottom plate.
• Automatic feed is advancing line too much or too little: If the line advances too much when you bump it (for bump feed) or automatically (for auto feed), you have wound too much line on the spool. Remove the spool and unwind 1–2 turns of line, then reinstall it. If the line does not advance at all, you have not wound enough line – add 1–2 more turns and test again.

Frequently Asked Questions

How often should I restring my Husqvarna weed eater?

It depends on how frequently you use it. For light residential use (1–2 times per week), you will need to restring every 2–4 weeks. For heavy commercial use, you may need to restring once a week or more. If you notice the line is worn down to less than 2 inches, frayed, or breaking frequently, it is time to restring, regardless of how long it has been since your last replacement.

Can I use third-party trimmer line instead of Husqvarna brand?

Yes, as long as the line diameter matches your trimmer head’s rating. Third-party line is often cheaper and works just as well as brand-name line, as long as it is high-quality. Avoid cheap, brittle line, as it will break more often and wear out faster. For heavy-duty use, opt for serrated or square line for better cutting power.

Why does my trimmer line keep coming loose after restringing?

This is usually caused by two issues: the line was not wound tightly enough around the spool, or the retaining ring is not fully snapped into place. When winding the line, pull it tight as you go to avoid gaps. When installing the retaining ring, press down firmly around the entire edge until you hear a click, confirming it is fully seated. For fixed line heads, make sure the line is wedged tightly in the slots, not just sitting loosely.

What size trimmer line does my Husqvarna weed eater use?

Most residential Husqvarna models use .065″ or .080″ diameter round line. Commercial models often use .095″ or .120″ diameter line, or serrated/square line for heavy brush. You can find the recommended size printed on the side of the trimmer head, or listed in your owner’s manual. Never use a larger line diameter than recommended, as it can damage the head and engine.

Can I restring my Husqvarna weed eater while it’s still attached to the engine?

No, always disconnect the spark plug wire (for gas models) or remove the battery (for cordless models) before restringing. Even if the trimmer is turned off, it can accidentally start if you bump the trigger, which can cause serious injury. Always treat the trimmer as if it is powered on while you are working on the head.

How do I know when my trimmer line is too worn to use?

Replace your line if it is frayed, has deep nicks or cuts, or is worn down to less than 2 inches in length. Worn line cuts less efficiently, puts extra strain on your engine, and is more likely to break while you are trimming. It is always better to replace line early, rather than waiting until it breaks mid-job.

Conclusion

By now, you should have a clear understanding of How to String a Husqvarna Weed Eater?, no matter what type of trimmer head you have. Restringing is a simple, low-cost maintenance task that anyone can master with a little practice, and it will save you time, money, and hassle in the long run. Remember to always follow safety precautions, use the correct line size and type for your model, and wind the line tightly to avoid common issues like jams and line breakage. If you run into problems, refer to the troubleshooting section above, or check your owner’s manual for model-specific instructions. With regular restringing and proper maintenance, your Husqvarna weed eater will stay in top condition for years, making yard work faster and easier every time.
