Understanding Your Tanaka Weed Eater and Its Trimmer Line System

Before you start restringing, it’s important to understand the two primary types of trimmer heads used on Tanaka weed eaters, as the restringing process varies significantly between them. Knowing which type you have is the first step to mastering How to String a Tanaka Weed Eater? correctly the first time.

Types of Tanaka Trimmer Heads

Tanaka weed eaters come with either bump feed (also called bump-and-go) or fixed line (also called semi-automatic or manual feed) trimmer heads, each designed for different use cases:

• Bump feed heads: These are the most common type on residential Tanaka models. They feature a spring-loaded spool inside the head that is pre-wound with trimmer line. When the line wears down during use, you tap the head lightly on the ground to rotate the spool slightly and release 2 to 3 inches of new line. Bump feed heads are ideal for casual residential use, as they allow you to extend line quickly without stopping work.
• Fixed line heads: These are standard on heavy-duty commercial Tanaka models designed for thick brush and frequent use. Instead of a wound spool, fixed line heads have two or four small holes on the sides of the head. You thread pre-cut lengths of line through these holes and secure them with knots to create the cutting swath. Fixed line heads are more durable for heavy-duty use, as the line is less likely to jam when cutting thick, woody vegetation.

You can usually identify your head type by looking at the design: bump feed heads have a smooth, round spool cover, while fixed line heads have small protruding holes on the sides for threading line. If you’re still unsure, check the model number printed on the head and look up the specifications in your owner’s manual or online.

What You’ll Need to String a Tanaka Weed Eater

Gathering the right supplies before you start will make the restringing process faster, safer, and more effective. Make sure you have these items on hand:

• Correct replacement trimmer line: Check your Tanaka owner’s manual for the recommended diameter and length. Most residential models use 0.080-inch round line, while heavy-duty commercial models may require 0.095-inch or 0.105-inch line. The correct size is also often printed on the side of the existing spool or trimmer head. Make sure the line is specifically designed for weed eaters, as regular rope or string will break easily and damage your tool.
• Scissors or heavy-duty line cutter: To cut the line to the correct length and trim excess after assembly. Dull cutters will fray the line ends, leading to breakage during use.
• Work gloves: Trimmer line is sharp and can cause deep cuts to your hands during handling, especially when winding it tightly around a spool.
• Safety glasses: To protect your eyes from flying debris, grass clippings, and line fragments while you work and test the trimmer.
• Small flathead screwdriver or trimmer line removal tool: To release the spool lock on bump feed heads that do not have a twist-lock mechanism.
• Cleaning brush or old rag: To remove caked-on grass, dirt, and debris from the trimmer head before restringing. Built-up gunk can cause the spool to stick and the line to jam, even if you restring it correctly.

Step-by-Step Guide to Stringing a Tanaka Weed Eater

The exact restringing steps vary slightly depending on your trimmer head type, but all Tanaka weed eaters follow a similar basic process. Always start with universal safety and preparation steps to avoid injury or damage to your tool.

Universal Prep Steps (For All Head Types)

1. Disconnect the power source completely. For gas-powered Tanaka models, remove the spark plug wire from the spark plug to prevent accidental startup. For electric or battery-powered models, remove the battery from the tool or unplug it from the power outlet. If you have a gas model, make sure the engine is cool before touching the spark plug to avoid burns.
2. Lay the weed eater on a flat, stable surface with the trimmer head facing up. This keeps small parts from rolling away and makes it easier to access the spool or line holes.
3. Clean the trimmer head thoroughly with a brush or rag to remove all caked-on grass, dirt, and debris. Built-up gunk can cause the spool to stick and the line to jam, so a clean head ensures smooth operation after restringing.

Once you’ve completed these prep steps, follow the instructions for your specific trimmer head type below.

How to String a Tanaka Weed Eater with a Bump Head

Most residential Tanaka weed eaters use bump feed heads, which are the easiest and fastest to restring. Follow these steps for a smooth, error-free process:

1. Remove the spool from the trimmer head. Look for a locking tab or twist-lock mechanism on the side of the head. Press the tab down or twist the head counterclockwise to release the spool cover, then pull the spool straight out of the head. Take note of how the spool is oriented inside the head before removing it, so you can reinsert it correctly later. If your spool has a small spring inside, take care not to lose the spring when removing the spool, as it is required for the bump feed mechanism to work.
2. Remove any remaining old line from the spool. If the line is stuck, use a flathead screwdriver to gently pry it loose. Discard the old line properly to avoid litter.
3. Wind the new trimmer line around the spool. Most Tanaka bump heads require you to wind the line in a clockwise direction (check the arrow printed on the spool for confirmation). Leave 6 to 8 inches of line hanging off the end of the spool before you start winding, to feed through the eyelets later. Wind the line tightly and evenly around the spool, making sure there are no gaps or overlapping layers. Overfilling the spool will cause the line to jam, so stop winding when the line is level with the edges of the spool.
4. Feed the line ends through the eyelets. There are usually two small holes (eyelets) on opposite sides of the spool. Thread each end of the wound line through one eyelet, pulling it through until there is a 6 to 8 inch tail on each side. Do not tie knots in the line ends, as this will prevent the line from feeding properly when you bump the head.
5. Reinsert the spool into the trimmer head. Align the spool with the slots inside the head, making sure the line tails are positioned correctly. Push the spool in until it clicks into place, then twist the head clockwise or snap the locking tab back into place to secure the spool cover.
6. Test the line feed. Reconnect the power source (spark plug, battery, or power cord) and turn on the weed eater. Tap the head lightly on the ground a few times to release line. If 2 to 3 inches of line extends with each tap, the restringing was successful. Trim any excess line with your cutter so it is even on both sides.

How to String a Tanaka Weed Eater with a Fixed Line Head

Fixed line heads are common on heavy-duty Tanaka models designed for thicker brush and commercial use. These heads do not have a wound spool, so you’ll replace the line with pre-cut lengths. Follow these steps for proper installation:

1. Remove the trimmer head from the weed eater if required by your model. Some fixed line heads twist off directly from the drive shaft, while others require you to remove a retaining bolt with a wrench. Check your owner’s manual for specific instructions for your model to avoid damaging the drive shaft threads.
2. Remove any old line remnants from the head. Pull out any broken pieces of line still threaded through the holes, and clean out any debris from the line holes and head interior with a brush or rag.
3. Cut equal lengths of trimmer line (two lengths for standard 2-line heads, four for 4-line heads). The length should be 1 to 2 feet longer than the cutting diameter of your weed eater, to give you enough slack to thread and tie knots. For example, if your weed eater has a 16-inch cutting swath, cut 18 to 20 inch lengths of line.
4. Thread the line ends through the head holes. Insert one end of a line length through a hole on the side of the head, pushing it through until equal lengths of line are sticking out of both sides of the head. Repeat for the second (and third, fourth) line hole.
5. Secure the lines with knots. Tie a simple overhand knot in the end of each line on the outside of the head to prevent it from pulling through the hole. Some models require a double knot for thicker line diameters, so check your owner’s manual for specific requirements. Make sure the knots are tight, but not so large that they get stuck in the head when you reassemble it.
6. Reattach the trimmer head to the weed eater, twisting it clockwise until it is tight, or replacing the retaining bolt and tightening it with a wrench. Do not overtighten, as this can damage the threads on the drive shaft.
7. Trim the line to the correct length. Turn on the weed eater and let the line extend to its full cutting diameter, then trim the ends evenly with your line cutter so they are the same length on all sides.

Choosing the Right Trimmer Line for Your Tanaka

Using the wrong trimmer line is one of the most common causes of jams, poor cutting performance, and damage to your Tanaka weed eater. The right line depends on your model’s specifications and the type of vegetation you trim regularly. Below is a comparison of common trimmer line types to help you choose the best option for your needs:

Always reference your owner’s manual for the maximum line diameter your model can handle, as using line that is too thick can overload the engine and damage the trimmer head. When in doubt, start with the manufacturer’s recommended size: if you frequently cut thick brush, you can step up to the next thicker size if your model supports it. Using a line that is too thin will cause it to break constantly, while a line that is too thick will put excess strain on the engine and can cause the trimmer head to overheat or fail prematurely.

Tips and Best Practices for Longer-Lasting Trimmer Line

Following these simple tips will extend the life of your trimmer line, reduce how often you need to restring your Tanaka weed eater, and keep your tool running smoothly:

• Wind the line tightly and evenly: Loose, uneven winding causes the line to catch on the spool and jam, reducing how often you’ll need to restring. Take your time when winding to ensure there are no gaps or overlapping layers.
• Do not overfill the spool: Leave a small gap between the wound line and the edge of the spool. Overfilling prevents the spool from rotating freely, which stops the line from feeding when you bump the head.
• Store extra line in a cool, dry place: Trimmer line becomes brittle and breaks easily if exposed to direct sunlight, extreme heat, or moisture for long periods. Keep spare line in a sealed container in a shaded, temperature-controlled area.
• Replace line before it gets too short: Letting the line wear down to less than 3 inches increases the risk of the line breaking mid-use and damaging the trimmer head. Replace the line as soon as it reaches this length.
• Clean the trimmer head every 3 to 5 uses: Built-up grass and dirt can cause the spool to stick and the line to jam, so regular cleaning extends the life of both the line and the head. Use a brush or rag to wipe out the head interior each time you restring.
• Use the correct line for your cutting needs: Using heavy-duty star-shaped line for light grass trimming is unnecessary and will wear out faster, while using thin round line for thick brush will break constantly. Match your line type to your typical use case for the best performance and longevity.
• Check for head alignment regularly: If you notice the line is wearing down unevenly, check that the trimmer head is not bent or damaged. A misaligned head will cause the line to wear faster on one side and reduce cutting performance.

Common Mistakes to Avoid When Stringing a Tanaka Weed Eater

Even experienced DIYers make mistakes when restringing their Tanaka weed eater, leading to jams, poor performance, and unnecessary wear on the tool. Avoid these common errors to get the best results:

• Winding the line in the wrong direction: Most Tanaka bump heads require clockwise winding, but some models use counterclockwise. Check the arrow printed on the spool before winding, as winding in the wrong direction will prevent the line from feeding when you bump the head.
• Using the wrong line diameter: A line that’s too thin will break easily, while a line that’s too thick will overload the engine and damage the trimmer head. Always reference your owner’s manual for the recommended size before purchasing replacement line.
• Skipping the safety step of disconnecting the power source: Gas-powered Tanaka weed eaters can start unexpectedly if the spark plug wire is still connected, leading to serious injury. Always disconnect power completely before working on the head.
• Not cleaning the trimmer head before restringing: Debris inside the head can cause the spool to stick and the line to jam, even if you restring it correctly. Take a few minutes to clean the head before starting the restringing process.
• Tying knots in the line ends for bump feed heads: Bump feed heads rely on the line sliding freely through the eyelets to feed. Knots will block the line and prevent it from extending when you tap the head on the ground.
• Using dull cutters to trim the line: Dull scissors or line cutters will fray the ends of the line, causing it to break easily during use. Use sharp, heavy-duty cutters to get a clean, smooth cut every time.

Troubleshooting Common Trimmer Line Issues

Even if you restring your Tanaka weed eater correctly, you may run into occasional issues during use. Here are fixes for the most common problems:

• Line jams frequently after restringing: This is almost always caused by overfilling the spool, winding the line loosely, or failing to clean debris out of the head. Remove the spool, rewind the line tightly and evenly, leaving a small gap between the line and the spool edge, and clean all debris from the head interior before reassembling.
• Line breaks constantly during use: This is usually due to using the wrong line diameter, using old or brittle line, or hitting rocks, concrete, or other hard surfaces while trimming. Replace the line with the correct diameter and fresh, high-quality line, and avoid contact with hard surfaces when possible.
• Line won’t feed when you bump the head: Check that you wound the line in the correct direction, that there are no knots in the line ends, and that the spool is seated correctly in the head. If the problem persists, the spring inside the bump head may be broken and need replacement.
• Trimmer head spins but doesn’t cut: This is usually caused by the line being too short, or the line ends being uneven. Extend the line by bumping the head a few times, or trim the ends to the same length to restore cutting performance.
• Trimmer head vibrates excessively after restringing: This is almost always caused by an unevenly wound spool or a spool that is not seated correctly in the head. Remove the spool, rewind the line tightly and evenly, and reinsert it making sure it clicks into place properly.

Frequently Asked Questions

How often should I restring my Tanaka weed eater?

The frequency of restringing depends on how often you use the tool and the type of vegetation you trim. For light residential use (1 to 2 hours per week), you’ll likely need to restring every 2 to 3 months. If you use the weed eater for heavy-duty trimming or cut thick, woody brush, you may need to restring every 1 to 2 weeks. Always replace the line when it wears down to less than 3 inches, as this prevents breakage and damage to the trimmer head. If you notice the line is wearing down faster than usual, you may need to restring more often, especially if you are trimming near abrasive surfaces like concrete or gravel.

Can I use third-party trimmer line on my Tanaka weed eater?

Yes, you can use high-quality third-party trimmer line on your Tanaka weed eater, as long as it matches the diameter and type recommended in your owner’s manual. Avoid cheap, low-quality line, as it is more likely to break, jam, and wear out quickly, which can cause damage to your trimmer head over time. Stick to reputable brands that offer compatible line for Tanaka models to ensure the best performance and longevity.

What size trimmer line does my Tanaka weed eater use?

The recommended line size varies by model. Most residential Tanaka weed eaters use 0.080-inch round line, while heavy-duty commercial models use 0.095-inch or 0.105-inch line. The correct size is listed in your owner’s manual, and it is also often printed on the side of the trimmer head. Using a line that is too large for your model can overload the engine and damage the head, so always confirm the correct size before purchasing replacement line.

Why does my trimmer line keep jamming after restringing?

Line jams are almost always caused by one of three issues: overfilling the spool, winding the line loosely or unevenly, or failing to clean debris out of the trimmer head before restringing. To fix the problem, remove the spool, rewind the line tightly and evenly, leave a small gap between the line and the spool edge, and clean all debris from the head interior before reassembling. If jams persist, check that you are using the correct line diameter for your model.

Do I need to replace the entire spool when restringing my Tanaka weed eater?

No, you do not need to replace the entire spool for most Tanaka bump feed heads. The spool is designed to be reused indefinitely, as long as it is not cracked or damaged. Only replace the spool if it is broken, has stripped threads, or the spring mechanism is no longer working. For fixed line heads, you do not need to replace the entire head when restringing, unless the head itself is damaged.

Can I restring a Tanaka weed eater without removing the head?

For most bump feed Tanaka models, you do not need to remove the entire head from the weed eater to restring it. You can access the spool by removing the spool cover on the side of the head while the head is still attached to the drive shaft. However, for fixed line heads, you will usually need to remove the entire head from the weed eater to access the line holes and thread the new line. Check your owner’s manual for model-specific instructions.

Conclusion

Learning How to String a Tanaka Weed Eater? is a simple, cost-effective skill that saves you time and money on professional repairs or replacement parts. By identifying your trimmer head type, gathering the right supplies, following the step-by-step instructions for your specific head, and avoiding common mistakes, you can restring your tool in 10 to 15 minutes and get back to yard work quickly. Remember to use the correct trimmer line for your model, follow best practices for line maintenance, and address any issues promptly to keep your Tanaka weed eater running smoothly for years to come.
