Why and When to Reload the Wire
Most Kobalt weed eaters use a replaceable spool of nylon string that extends through small holes in the cutting head. Over time, the line wears down from contact with grass, weeds, and hard surfaces. When the line becomes too short or breaks repeatedly, the trimmer loses effectiveness.
Typical signs that you need to reload include:
- The string no longer feeds out automatically or manually.
- You see only a few inches of line remaining on the spool.
- The trimmer stops cutting grass efficiently.
- You hear unusual noises from the cutting head.
Reloading the wire is a straightforward process that usually takes ten to fifteen minutes once you know the steps.
Tools and Materials You Will Need
Before starting, gather the following items to keep the job smooth and safe:
- New trimmer line compatible with your Kobalt model.
- A pair of work gloves to protect your hands.
- Safety glasses to shield your eyes from debris.
- A flat workspace or bench vise to hold the trimmer securely.
- A small flathead screwdriver for prying open stubborn spools.
- A pair of scissors or wire cutters for trimming excess line.
Having everything ready prevents interruptions and reduces the risk of accidents during disassembly.
How to Identify Your Kobalt Model
Kobalt produces several weed eater models, each with slightly different spool designs. Locating your model number helps ensure you purchase the correct replacement line and follow the right instructions.
To find your model number:
- Turn off the trimmer and disconnect the battery if it is cordless.
- Look for a metal or plastic label on the motor housing or the shaft.
- The label typically displays a model number such as
KWLT2020orKST2020B. - If the label is missing, check the original packaging or your online purchase receipt.
You can also search the model number on the Kobalt website or contact customer support for a user manual specific to your unit.
Preparing Your Trimmer for Reload
Safety comes first. Even if the trimmer is unplugged, take these steps before opening the cutting head:
- Disconnect the battery or unplug the unit completely.
- Press the trigger several times to release any residual power in the system.
- Place the trimmer on a stable surface or secure it in a bench vise with padded jaws.
- Wear safety glasses and work gloves throughout the process.
This preparation minimizes the chance of accidental startup and protects you from sharp plastic edges.
Removing the Old Line
Most Kobalt trimmers use a semi-automatic or bump-feed spool system. To remove the old line:
- Locate the release button or latch on the side or bottom of the cutting head.
- Press the release and gently pull the head upward to detach it from the gear housing.
- Twist or slide the spool cover off according to your model’s design.
- Pull the old line out of the eyelets and unwind any remaining string from the spool.
- Inspect the spool and housing for debris, dirt, or damaged components.
If the line is tangled or stuck, use a flathead screwdriver to gently pry it loose. Avoid forcing anything, as this can damage the internal mechanism.
Choosing the Right Replacement Line
Not all trimmer lines are created equal. Using the wrong thickness or material can cause poor performance or damage the head. Here is how to choose the right one:
- Check your user manual for the recommended line diameter.
- Common sizes for Kobalt models include 0.065 inch, 0.080 inch, and 0.095 inch.
- Choose a line made of high-quality nylon for durability and flexibility.
- Consider the type of vegetation you trim most often when selecting line thickness.
If you cannot locate the manual, a quick search for your model number plus “trimmer line” online will reveal compatible options sold by Kobalt or third-party manufacturers.
String Line Types Compared
Different line shapes and materials offer distinct advantages. Review the table below to pick the best option for your needs.
| Line Type | Best For | Advantages | Disadvantages |
|---|---|---|---|
| Round Standard | Light trimming | Inexpensive and widely available | Wears quickly on thick weeds |
| Square or Star | Heavy-duty trimming | Cuts through thick grass and weeds | Can be noisy and harsh on surfaces |
| Twisted or Cable | Medium to heavy vegetation | Good balance of durability and cutting | More expensive than round line |

Step-by-Step Guide to Put Wire in Kobalt Weed Eater
Now that you have gathered your tools and materials, follow these detailed steps to reload the wire in your Kobalt weed eater.
Step 1: Prepare the Spool
After removing the old line, clean the spool with a dry cloth. Check for any grooves or arrows printed on the spool that indicate the correct winding direction. Winding against the arrow can cause tangles and uneven feeding.
Step 2: Cut the New Line
Measure and cut a length of new trimmer line. A good rule of thumb is to use about nine feet for standard Kobalt models. If your model requires two lines, cut two equal lengths. Having extra line is better than running short mid-job.
Step 3: Find the Anchor Point
Look for a small hole or notch on the center hub of the spool. This is the anchor point. Tie a simple overhand knot in one end of the line and insert it through the hole. Pull it tight so the knot sits flush against the spool.
Step 4: Wind the Line
Hold the spool in one hand and begin winding the line in the direction indicated by the arrow on the spool. Keep moderate tension on the line as you wind to prevent loose coils. Continue until you reach the end of the line, leaving about six inches unwound for feeding.
Step 5: Secure the End
Once you reach the end, press the line into the groove around the edge of the spool or clip it into any retaining tabs. This prevents the line from unwinding while you reinstall the spool.
Step 6: Reinstall the Spool
Align the spool with the housing and press it back into place. Make sure it sits level and rotates smoothly. Reattach the spool cover and secure any latches or screws.
Step 7: Feed the Line Through the Eyelets
Locate the small holes or eyelets on the cutting head. Push the end of the line through one eyelet until about half an inch protrudes. If your model uses dual lines, repeat on the opposite side.
Step 8: Test the Feed
Gently pull the line to confirm it feeds freely. For automatic feed models, briefly squeeze the trigger to advance the line. Do not overfeed, as this can cause tangling.
Automatic Feed vs. Manual Feed Heads
Kobalt offers both automatic feed and manual feed cutting heads depending on the model. Understanding the difference helps you handle each correctly.
Automatic Feed (Bump Feed): These models release line automatically when you tap the head on the ground. Reload by winding the spool as described above and ensuring the line passes through the internal channel.
Manual Feed: Some models require you to manually pull line from a button or lever. These are simpler to reload but require more attention during use to maintain proper line length.
Refer to your user manual to confirm which type your model uses, as the reloading technique can vary slightly.
Testing the New Line
After installing the new wire, reconnect the battery or plug in the trimmer. Perform a brief test in a safe area away from people or fragile objects.
- Start the trimmer and let it idle for a few seconds.
- Squeeze the trigger gently to spin the head.
- Observe whether the line extends and retracts smoothly.
- Listen for unusual noises or vibrations.
If the line feeds unevenly or fails to extend, power off the tool and recheck the spool installation and line alignment.
Tips and Best Practices
Follow these expert tips to maximize the life of your trimmer line and reduce future maintenance:
- Always wind the line in the correct direction shown on the spool.
- Keep moderate tension while winding to avoid loose coils.
- Store spare line in a cool, dry place away from direct sunlight.
- Replace the line before it becomes completely depleted to avoid running the spool dry.
- Use a line thickness recommended by Kobalt for your specific model.
- Clean the cutting head regularly to remove grass clippings and debris.
- Check the eyelets for wear and replace the head if they become enlarged.
Developing these habits will keep your Kobalt weed eater performing at its best season after season.
Common Mistakes and How to Avoid Them
Even experienced users sometimes make errors when reloading the wire. Here are the most frequent mistakes and how to prevent them:
- Wrong winding direction: Always follow the arrow on the spool. Reversing the direction causes tangles and jamming.
- Insufficient line length: Cutting too little line means it runs out quickly. Stick to the recommended length for your model.
- Loose winding: Slack in the spool leads to uneven feeding and frequent restarts. Maintain steady tension while winding.
- Incorrect line thickness: Using line that is too thick or too thin can strain the motor or fail to cut effectively.
- Skipping the anchor knot: Without securing the end, the entire line can unravel inside the head.
- Rushing reassembly: Taking time to align and secure all parts prevents operational issues later.
By paying attention to these details, you can avoid frustration and enjoy reliable performance.
