Understanding Your Husqvarna Weed Eater

Before you start the restringing process, it’s helpful to understand the basic components of your Husqvarna trimmer, especially the trimmer head, which houses the string spool. Husqvarna produces a wide range of weed eaters, including gas-powered, electric corded, and battery-powered models, but the restringing process is nearly identical across all of them, with only minor differences in spool release mechanisms. The two most common types of trimmer heads used on Husqvarna models are bump-feed and fixed-line heads, each with its own advantages and restringing requirements.

Types of Husqvarna Trimmer Heads

Bump-feed heads are the most common on residential Husqvarna trimmers. They work by releasing a small amount of string each time you tap the bottom of the head on the ground while the trimmer is running. This makes them convenient for quick adjustments on the go, but they require more frequent restringing because they hold less string than fixed-line heads. Bump-feed heads are ideal for casual users who only trim their yard once a week or less.

Fixed-line heads are more common on commercial-grade Husqvarna trimmers. They require you to manually feed new string through the head when the existing string wears down, but they hold much more string than bump-feed models, so you only need to restring every few weeks even with heavy use. Fixed-line heads are better suited for professionals or homeowners with large, overgrown properties who need to trim for hours at a time.

Identifying Your Model’s String Requirements

Using the wrong string diameter for your trimmer is one of the most common causes of poor performance and premature wear. The correct string size for your Husqvarna model is listed in the user manual, but you can also find it by checking the existing spool or the label on the trimmer body. Most residential Husqvarna trimmers use .080-inch or .095-inch round or square string, while commercial models use .095-inch to .120-inch twisted or square string for extra durability. Never use string thicker than the manufacturer’s recommended size, as this will overload the engine, cause excessive vibration, and can even damage the spool or drive shaft.

Tools and Materials You’ll Need

Restringing your Husqvarna weed eater requires very few tools, most of which you likely already have on hand. Having everything ready before you start will make the process faster and more efficient. Here’s what you’ll need:

• Replacement trimmer string: Make sure to purchase string that matches the diameter and shape (round, square, or twisted) recommended for your specific Husqvarna model. You can buy bulk string by the roll or pre-wound spools for faster swaps.
• Flathead screwdriver: Some Husqvarna trimmer heads require a flathead screwdriver to release the spool lock tab, though many modern models have a twist-lock mechanism that doesn’t require tools.
• Work gloves: Trimmer string has sharp edges that can cut your fingers, especially when you’re pulling it tight or winding it around the spool.
• Clean rag: Use this to wipe away grass clippings, dirt, and debris from the trimmer head before you start, to avoid getting grit in the spool mechanism.
• Optional: Trimmer line lubricant: This silicone-based lubricant reduces friction between the string and the trimmer head, extending the life of your string and reducing wear on the spool.

Most Husqvarna trimmers come with a small combination wrench that fits the spool nut, so you likely won’t need any additional specialized tools for the job.

Safety Precautions Before Starting

While restringing a weed eater is a low-risk task, taking a few basic safety precautions will prevent injuries and damage to your trimmer. Follow these steps before you begin work:

1. Disconnect the power source completely: For gas-powered Husqvarna trimmers, turn off the fuel valve and disconnect the spark plug wire from the spark plug to prevent accidental startup. For electric corded models, unplug the trimmer from the outlet. For battery-powered models, remove the battery pack from the trimmer body.
2. Wear protective gear: Put on work gloves to protect your hands from sharp string edges, and safety glasses to guard against snapped string or flying debris.
3. Work on a stable, flat surface: Lay the trimmer on a workbench or the ground in a well-lit area, so you don’t have to balance it while you work.
4. Clean the trimmer head first: Use your rag to wipe away any grass clippings, mud, or dirt from the spool and surrounding area. Grit and debris can get trapped in the spool mechanism and cause the string to jam or break prematurely.

Never attempt to restring a trimmer while it is running or connected to a power source, as this can lead to serious lacerations or other injuries.

Step-by-Step Guide to Restringing Your Husqvarna Weed Eater

Now that you have your tools ready and have taken the necessary safety precautions, you’re ready to restring your trimmer. The process takes 10 minutes or less for most users, and follows the same basic steps for all Husqvarna models. Below is a detailed walkthrough for each step of the process.

Step 1: Prepare the Trimmer

Start by laying your Husqvarna trimmer on a flat, stable surface with the trimmer head facing up. Double-check that the power source is fully disconnected: for gas models, make sure the spark plug wire is pulled off the plug and the fuel valve is closed; for electric/battery models, confirm the battery is removed or the cord is unplugged. Put on your work gloves, then use your clean rag to wipe away any grass, dirt, or debris from the trimmer head and spool area. Next, locate the spool release mechanism on your model: most modern Husqvarna trimmers use a twist-lock spool that releases by turning counterclockwise, while older models may have a small release tab that you press with a flathead screwdriver. Consult your user manual if you can’t locate the release mechanism.

Step 2: Remove the Old String

If your trimmer has a twist-lock spool, grip the spool firmly and turn it counterclockwise until it releases from the drive shaft, then pull it straight off. If your model uses a tab release, press the small tab on the side of the head with your screwdriver, then pull the spool straight off the drive shaft. Once the spool is removed, pull out any remaining old string from the spool and the string feed slots on the trimmer head. Dispose of the old string properly, as it can be a tripping hazard or cause injury to pets and wildlife if left lying around. If the spool is reusable, wipe it down with your rag to remove any built-up grass or dirt before proceeding.

Step 3: Prepare the New Trimmer String

If you purchased a pre-wound spool, you can skip this step and move directly to loading the new string. If you are winding the string yourself, start by measuring out the correct length of string for your model: most residential bump-feed heads require 10 to 15 feet of string, while commercial fixed-line heads require 20 to 30 feet. Cut the string to length with scissors or a utility knife, then find the midpoint of the string length and tie a simple overhand knot to secure it to the center hub of the spool. Next, wind the string evenly around the spool, in the direction the trimmer head rotates (almost all Husqvarna models rotate clockwise, but check your user manual to confirm). Wind the string tightly but not so tight that it stretches or kinks, and leave 6 to 8 inches of string hanging out of the feed slots on each side of the spool so you have enough to feed through the trimmer head.

Step 4: Load the New String

Take your wound spool (or pre-wound spool) and align the notches on the edge of the spool with the slots on the trimmer head. Slide the spool onto the drive shaft, then secure it in place: for twist-lock models, turn the spool clockwise until you feel it lock into place; for tab-release models, push the spool onto the shaft until you hear a click. Pull both ends of the string tight to make sure they are seated correctly in the feed slots, and that there is no slack or tangling in the string. If the string is not feeding through the slots correctly, remove the spool and adjust the string so it sits properly in the guides.

Step 5: Reassemble the Trimmer

If you removed a guard, cover, or spool nut to access the spool, replace it now and secure any screws or clips to hold it in place. Make sure the spool is seated tightly against the trimmer head, with no wobbling or movement when you wiggle it. Next, reconnect the power source: for gas models, reattach the spark plug wire to the spark plug; for electric models, plug the trimmer back into the outlet; for battery models, slide the battery pack back into the designated slot on the trimmer body. Double-check that all components are secure before moving to the test step.

Step 6: Test the Trimmer

Start your Husqvarna trimmer according to the manufacturer’s instructions: gas models may require a few priming pulls and a pull start, while electric and battery models will start with the press of a button. Let the trimmer run for 10 to 15 seconds at idle, then tap the bottom of the trimmer head on the ground (for bump-feed models) to release more string. Check that the string extends evenly from both sides of the head, and that it does not get tangled or jam when you rev the engine. If the string does not extend, turn off the trimmer, disconnect the power source, and adjust the string to make sure it is seated correctly in the feed slots. Once the string is extending properly, you’re ready to use your trimmer.

Tips for Easier Future Restringing

Once you’ve mastered the basic restringing process, these tips will make future restringing even faster and easier, while extending the life of your string and trimmer:

• Wind string in a warm room: Cold trimmer string is stiff and prone to kinking, making it harder to wind evenly. If you’re restringing in cold weather, leave the string roll in your house for 30 minutes before you start to warm it up.
• Use a winding guide: Place a piece of cardboard with a slot cut in the center over the spool while you wind, to keep the string layers even and prevent overlapping, which can cause jams.
• Keep spare pre-wound spools on hand: Pre-wound spools eliminate the need to measure and wind string yourself, so you can swap out a worn spool in 30 seconds or less. They’re especially useful for commercial users who restring frequently.
• Lubricate your string regularly: Applying a small amount of trimmer line lubricant to the string every few uses reduces friction, prevents the string from drying out and becoming brittle, and extends its life by up to 50%.
• Store spare string properly: Keep unused string in a sealed plastic bag in a cool, dry place to prevent it from being exposed to sunlight and moisture, which can cause it to degrade and break prematurely.

Common Mistakes to Avoid

Even experienced trimmer users make these common mistakes when restringing, which can lead to poor performance, broken string, or damage to your trimmer. Avoid these errors to make the process smoother:

• Using string that’s too thick: As mentioned earlier, using a string diameter larger than the manufacturer’s recommendation will overload the trimmer’s engine, cause excessive vibration, and can even break the spool or drive shaft. Always check your user manual for the correct string size before purchasing replacement string.
• Winding the string too tightly: Winding the string as tight as possible may seem like it will keep it from slipping, but it actually causes the string to stretch and kink, leading to breakage during use and difficulty feeding out new string. Wind the string tightly enough that it doesn’t slip on the spool, but loose enough that you can slightly flex the layers with your finger.
• Winding the string in the wrong direction: If you wind the string counterclockwise on a model that rotates clockwise, the string will tangle immediately when you start the trimmer. Always wind the string in the same direction the head rotates, which is almost always clockwise for Husqvarna models.
• Forgetting to disconnect the power source: This is the most dangerous mistake, as it can lead to accidental startup while your hands are near the trimmer head, causing serious lacerations. Always double-check that the power is disconnected before you touch the spool or string.
• Not leaving enough string hanging out of the feed slots: If you only leave 1-2 inches of string hanging out of the slots, you won’t have enough to feed out when the string wears down, meaning you’ll have to restring again immediately after the first use. Always leave 6-8 inches of string on each side after loading the spool.

Comparison of Husqvarna String Types

Choosing the right trimmer string for your Husqvarna weed eater is key to getting the best performance and longest life out of both the string and your trimmer. Below is a comparison of the most common Husqvarna string types, their ideal use cases, and their pros and cons:

For most residential users, .080-inch or .095-inch square string is the best balance of cost, durability, and cutting performance. Commercial users will get the best results from .095-inch or larger twisted string, which can handle even the toughest vegetation without breaking.

Frequently Asked Questions

Below are answers to the most common questions owners have when learning how to restring their Husqvarna weed eater:

How Often Should I Restring My Husqvarna Weed Eater?

The frequency of restringing depends on how often you use your trimmer and what type of vegetation you’re cutting. For light residential use (1-2 hours per week, cutting grass and thin weeds), you’ll need to restring every 2 to 4 weeks. For heavy commercial use (4 or more hours per day, cutting thick weeds, brush, and overgrown vegetation), you may need to restring every 1 to 2 days. You’ll know it’s time to restring when the string is worn down to less than 2 inches in length, even after tapping the head to feed out more string, or when the string breaks frequently during use.

Can I Use Third-Party String on My Husqvarna Trimmer?

Yes, you can use third-party replacement string on your Husqvarna trimmer as long as the string diameter and shape match the manufacturer’s recommendations for your specific model. Many high-quality third-party string options perform just as well as official Husqvarna string, at a lower cost. Just avoid using generic, low-quality string that is prone to breaking, as this can lead to frequent restringing and even damage to your trimmer’s spool and engine.

Why Does My New String Keep Breaking?

There are several common reasons new trimmer string breaks frequently. First, you may be using string that is too thick for your model, which puts excess strain on the string and engine. Second, you may have wound the string too tightly around the spool, causing it to snap under tension during use. Third, you may be cutting against hard surfaces like concrete, rocks, or tree trunks, which can break even high-quality string. Finally, the string may be old or brittle from sitting in storage for too long, especially if it was exposed to sunlight or extreme temperatures. To fix this, use the correct string size, wind it loosely but evenly, avoid hard surfaces when trimming, and store spare string in a cool, dry place.

How Do I Know If My String Is Worn Out?

The most obvious sign that your string needs to be replaced is when it is worn down to less than 2 inches in length, even after tapping the bump-feed head to release more string. You may also notice that the trimmer is less effective at cutting, requiring multiple passes to cut through grass and weeds. If the string is frayed, split, or has rough, uneven edges, it is also time to replace it, as these imperfections will cause it to break during use and can damage the trimmer head.

Is It Better to Buy a Pre-Wound Spool?

For most users, especially those who restring their trimmer infrequently, pre-wound spools are the better choice. Pre-wound spools are already wound to the correct tension and length, so you can swap them out in 30 seconds or less without having to measure and wind string yourself. They also eliminate the risk of winding errors that cause tangling, jamming, or breakage. The only downside is that pre-wound spools are slightly more expensive than bulk string, but the time and convenience savings are well worth the small extra cost for most homeowners.

Conclusion

Learning how to restring your Husqvarna weed eater is a simple, practical skill that will save you time and money on maintenance for years to come. By following the step-by-step guide above, using the correct string for your model, and avoiding common mistakes, you can restring your trimmer in 10 minutes or less, even if you’ve never done it before. Regular restringing keeps your trimmer performing at peak efficiency, ensures clean, even cuts, and extends the life of your equipment.
