Understanding Your Worx Weed Eater Model

Worx manufactures a wide range of string trimmer models designed for different use cases, from lightweight corded models for small yards to heavy-duty cordless models for large properties. While the core process for how to put string in Worx Weed Eater is nearly identical across all units, small differences in spool design and attachment mechanisms mean it’s helpful to identify your specific model before you start. The most popular Worx weed eater models include the WG150 (corded, ideal for small to medium yards), WG154 (20V cordless, lightweight for easy maneuverability), WG163 (20V cordless with command feed technology for automatic string extension), and WG170 (heavy-duty, for large properties and thick brush).

Most modern Worx trimmers use a tool-free spool release system, which means you can remove and replace the spool without any additional tools. Older models may have a twist-on spool cap that requires a small flathead screwdriver to remove, so checking your owner’s manual first will give you model-specific instructions. All Worx weed eaters use either 0.065” or 0.080” diameter cutting string, so verifying your model’s required string size before purchasing replacements will ensure compatibility and optimal performance. Most lightweight Worx corded and cordless trimmers (like the WG150 and WG154) use 0.065” diameter string, which is ideal for light grass and weeds. Heavier-duty models like the WG170 can handle 0.080” diameter string, which is better for cutting thick weeds, small brush, and overgrown vegetation. Using the wrong string size can cause poor cutting performance, frequent jams, and even damage to your trimmer’s motor over time.

Tools and Materials You’ll Need

One of the benefits of learning how to put string in Worx Weed Eater is that you don’t need any specialized tools or expensive supplies to complete the task. Most of the items you’ll need are likely already in your household toolbox. Gather the following supplies before you start to make the process as smooth as possible:

• Replacement cutting string: Purchase string that matches the required diameter for your Worx model (either 0.065” or 0.080”). A 50-foot roll is more than enough for multiple replacements, and you’ll only need 10-15 feet of string for a single spool load.
• Work gloves: Cutting string has sharp edges that can cut your fingers, especially when you’re pulling it taut to wind it around the spool. A pair of basic gardening or work gloves will protect your hands from injury.
• Clean rag: Use this to wipe away built-up grass, dirt, and debris from the spool and trimmer head before you start loading new string. A clean working area will prevent jams and ensure smooth string feeding.
• Scissors or string cutter: You’ll need this to cut the replacement string to the correct length for your model. A dedicated string trimmer line cutter works best, but sharp household scissors will also get the job done.
• Flathead screwdriver (optional): Only required for older Worx models with a twist-on spool cap that needs to be pried loose. Most modern models have a tool-free release, so this is not necessary for most users.

Once you have all your supplies gathered, find a flat, well-lit workspace to work in. A workbench or a clean area of your garage or patio is ideal, as it will give you plenty of room to lay out your parts and avoid losing small components like the spool release button.

Step-by-Step Guide to Loading String in Your Worx Weed Eater

Now that you have all your supplies ready, follow these simple steps to master how to put string in Worx Weed Eater quickly and correctly. This process works for nearly all Worx string trimmer models, but refer to your owner’s manual for any model-specific instructions.

Removing the Old Spool and Preparing for Replacement

Start by disconnecting the power source: unplug corded models or remove the battery from cordless units to avoid accidental startup. Flip the trimmer upside down on a flat surface, and use a clean rag to wipe away any built-up grass or debris from the spool area. Locate the spool release button on the bottom of the cutting head, press it firmly, and pull the old spool straight out. For older models with a twist-on cap, twist the cap counterclockwise to remove it. Pull the old string off the spool, and inspect the spool for cracks or damage. If the spool is broken, replace it with a new Worx spool before proceeding, as a damaged spool will cause jams with new string.

Loading New String Onto the Spool

This is the core step of the process for how to put string in Worx Weed Eater, and following these steps carefully will ensure the string feeds correctly when you use the trimmer:

1. Cut two equal lengths of replacement string, each 6-8 feet long (check your owner’s manual for the exact length required for your model). Cutting the string to the correct length will prevent overfilling the spool, which causes jams and poor feeding.
2. Find the midpoint of the two string lengths, and fold them in half to create a loop at the center. This loop will lock into the notch at the center of the spool to hold the string in place while you wind it.
3. Insert the looped end of the string into the small notch at the center of the spool. Make sure the loop is fully seated in the notch so it doesn’t slip out while you’re winding the string around the spool.
4. Wind the two loose ends of the string around the spool in the direction indicated by the arrow printed on the side of the spool. Almost all Worx spools have a clear directional arrow showing which way to wind; winding in the wrong direction is the most common cause of string jams and feeding issues. Keep the string taut as you wind to avoid loose loops that can cause tangles.
5. Wind the string until there is 4-6 inches of string sticking out from each side of the spool. Do not overfill the spool, as excess string will bunch up and jam the feeding mechanism during use.
6. Tuck each of the two loose string ends into one of the small notches on the edge of the spool. These notches hold the string in place while you reattach the spool to the trimmer head, preventing the string from unwinding completely as you work.

Reinstalling the Spool and Testing

Once the new string is loaded onto the spool, follow these steps to reattach it to your trimmer and test that it works correctly:

1. Line up the spool with the slot on the bottom of the cutting head, making sure the two loose string ends are pointing out through the string outlets on the sides of the cutting head. Press the spool firmly into place until you hear a click, which indicates it is locked into position. For models with a twist-on cap, twist the cap clockwise until it is tight to secure the spool.
2. Pull the two loose string ends gently to confirm they are properly seated in the edge notches and won’t come loose when the trimmer is running. If the string pulls out easily, remove the spool and re-seat the ends in the notches.
3. Reconnect the power source: plug your corded trimmer back into the outlet, or reinsert the battery pack into your cordless model.
4. Turn on the trimmer and let it run for 10-15 seconds. For bump-feed models, gently bump the cutting head against the ground to release more string; for automatic feed models, the string should extend automatically when the trimmer is running. If the string does not feed correctly, turn off the trimmer immediately, remove the spool, and double-check that you wound the string in the correct direction and that the ends are properly secured in the notches.

Pro Tips for Smooth String Loading

Once you master the basic process for how to put string in Worx Weed Eater, these pro tips will help you make the process even faster and extend the lifespan of your string and trimmer:

• Use the correct string diameter for your model: Always check your owner’s manual for the recommended string size. Using a thicker string than specified will put extra strain on your trimmer’s motor, while thinner string will break quickly and jam the feeding mechanism.
• Wind the string evenly and tightly: As you wind the string around the spool, keep it taut and make sure each coil sits neatly next to the previous one. Loose, uneven coils will cause tangles and jams, so if you notice the string bunching up as you wind, unwind it and start over to get an even coil.
• Replace the string early: Don’t wait until the string is only 1-2 inches long to replace it. Most experts recommend replacing the string when it reaches 3-4 inches in length, as shorter string puts extra strain on the spool mechanism and feeds poorly, leading to jams and uneven cutting.
• Store string properly: Keep extra replacement string in a cool, dry place away from direct sunlight. Exposure to UV light and moisture will make the string brittle and prone to breaking, reducing its lifespan and causing more frequent replacements.
• Practice gentle bump feeding: If you have a bump-feed Worx model, practice bumping the cutting head gently against the ground to release more string. Bumping too hard can damage the spool mechanism, while bumping too lightly won’t release the string. A light, quick bump is all that’s needed.

Common Mistakes to Avoid

Even experienced users make mistakes when learning how to put string in Worx Weed Eater. Avoiding these common errors will save you time and frustration:

• Winding the string in the wrong direction: This is the most frequent mistake users make, and it will cause the string to jam and not feed properly during use. Always check the directional arrow on the spool before winding, and if you’re unsure, wind the string so it comes off the top of the spool when you pull the loose ends.
• Overfilling the spool: It may seem like adding extra string will make it last longer, but overfilling the spool will cause the string to bunch up and jam the feeding mechanism. Stick to the recommended 4-6 inches of loose string on each side of the spool when you’re done winding.
• Using low-quality string: Cheap, generic string is more likely to break easily, fray, and jam the feeding mechanism, leading to more frequent replacements and potential damage to your trimmer’s motor. Opt for Worx OEM string or a high-quality third-party brand specifically designed for Worx trimmers for the best performance.
• Skipping the cleaning step: Failing to wipe down the spool and trimmer head before installing new string will leave behind grass and debris that can cause the string to jam or feed unevenly. Take 30 seconds to clean the area before you start loading new string to avoid this issue.
• Forgetting to secure the string ends: If you don’t tuck the loose string ends into the edge notches before reinstalling the spool, the string will unwind completely as you attach the spool, and you’ll have to start the loading process over. Always double-check that the ends are secured before reattaching the spool.

Recommended Worx Weed Eater String Comparison

While Worx OEM string is the safest choice for optimal performance and compatibility, there are several high-quality third-party options available that work well for most models. The table below compares the top string options for Worx weed eaters to help you choose the right one for your needs:

For most homeowners, the Worx OEM twisted string offers the best balance of durability, cutting performance, and reduced vibration, making it worth the slightly higher price point. If you only use your trimmer occasionally for light edging, a high-quality third-party round string is a budget-friendly option that works well for low-use scenarios. Avoid no-name generic string, as it is often made of low-quality materials that break easily and can damage your trimmer’s motor over time.

Frequently Asked Questions

Below are answers to the most common questions users have about loading string into their Worx weed eater:

How often should I replace my Worx weed eater string?

The frequency of string replacement depends on how often you use your trimmer and what you’re cutting. For light use (edging sidewalks and trimming light grass once a week), you’ll need to replace the string every 1-2 months. For heavier use (cutting thick weeds, small brush, or large areas of overgrown grass 2-3 times a week), you may need to replace the string every 2-4 weeks. Always replace the string when it becomes shorter than 3-4 inches, as this is when it starts to feed poorly and put extra strain on the trimmer’s motor.

Can I use third-party string in my Worx weed eater?

Yes, you can use high-quality third-party string in most Worx weed eater models, as long as it matches the required diameter for your specific trimmer. However, low-quality generic string is more likely to break easily, jam the feeding mechanism, and cause excess wear on your trimmer’s motor. If you choose to use third-party string, opt for a reputable brand that specifically states it is compatible with Worx trimmers to avoid performance issues and potential damage to your tool.

Why does my Worx weed eater string keep breaking?

There are several common reasons your Worx weed eater string may break frequently: using the wrong string diameter for your model, winding the string too tightly or too loosely on the spool, hitting rocks, concrete, or other hard objects while trimming, using old or brittle string that has been exposed to sunlight and moisture, or a damaged spool that is causing the string to catch and snap. To reduce breakage, make sure you’re using the correct string type, avoid trimming near hard surfaces, and store extra string in a cool, dry place when not in use.
