Understanding Your Black & Decker Weed Eater

Before you learn How to Reload Black and Decker Weed Eater? it’s important to understand the two main types of Black & Decker weed eaters on the market, as their reload processes and required components differ significantly. Knowing your model type will ensure you follow the correct steps and use the right parts to avoid damaging your tool.

Common Models and Their String Types

Black & Decker produces two primary categories of weed eaters: bump-feed and fixed-line models. Bump-feed models, such as the LST201 20V lithium-ion trimmer and the GKC1832 18V cordless grass trimmer, use a centrifugal mechanism that releases more trimmer line when you tap the bottom of the head on the ground. These models typically use round .065 or .080 inch diameter trimmer line, depending on the intended use. Fixed-line models, including the STC080 8A electric trimmer and the GH900 6.5A heavy-duty trimmer, require you to manually adjust the line length via a knob or lever on the head. Most fixed-line models use .065 inch round line, though heavy-duty variants may support .095 inch line for cutting thicker brush. Some fixed-line models also accept square or hex-shaped line for improved cutting power, but you will need to confirm compatibility with your user manual before switching line shapes.

Components You’ll Need for Reloading

Gathering the right supplies before you start reloading will make the process faster and reduce the risk of mistakes. You will need the following items:

• Replacement trimmer line in the correct diameter and shape for your model (check your user manual if you are unsure)
• A small flathead screwdriver (required for some models to open the spool cover)
• A tape measure or the built-in line cutter on your trimmer head (to cut line to the correct length)
• A clean, dry cloth (to wipe grass clippings and debris from the trimmer head)
• Work gloves (to avoid cuts from sharp trimmer line edges)

Most Black & Decker weed eaters come with a basic set of these tools, but it’s a good idea to keep a spare set in your garage for quick reloads.

When to Reload Your Weed Eater

Reloading your weed eater at the right time will prevent damage to the tool and avoid interruptions during yard work. Watch for these common signs that it’s time to reload:

• The trimmer head sputters and cuts unevenly, leaving patches of uncut grass or weeds
• Only 2-3 inches of line extend from the trimmer head, or no line is visible at all
• The line breaks repeatedly during use, even when cutting light grass
• The motor strains or makes a high-pitched noise, but the line isn’t cutting through weeds effectively

It’s best to reload your weed eater before the line is completely gone, as running the trimmer head with no line can damage the spool and put excess strain on the motor. If you notice a burning smell while using your tool, stop immediately and reload, as this is a sign the motor is overheating from working too hard to cut with insufficient line. For heavy-duty use on thick, overgrown weeds, you may need to reload every 1-2 hours, while light residential use may only require reloading every 2-3 uses.

Step-by-Step Guide to Reload Black & Decker Weed Eater

The reload process varies slightly depending on whether you have a bump-feed or fixed-line model, but all Black & Decker weed eaters follow the same basic safety and preparation steps first. Follow the instructions below for your specific model type to reload your tool correctly.

Pre-Reload Preparation Steps

These initial steps apply to all Black & Decker weed eater models, and will keep you safe and prevent damage to your tool: (See Also:How To Adjust Carb On Husqvarna Weed Eater)

1. Unplug the weed eater from the electrical outlet, or remove the battery pack if you have a cordless model. If your tool has a trigger lock, engage it to prevent accidental startup while you work.
2. Lay the weed eater on a flat, stable surface with the trimmer head facing up. This gives you easy access to the spool and prevents the tool from tipping over while you work.
3. Wipe away all grass clippings, dirt, and debris from the outside of the trimmer head with a clean cloth. Built-up debris can get into the spool compartment and cause the line to jam or advance unevenly.
4. Locate the release mechanism on the trimmer head. Most Black & Decker models have a small latch or button on the side of the head that you press to release the spool cover, though some older models require you to twist the cover counterclockwise to open it. Check your user manual if you cannot find the release mechanism.

Reloading a Bump-Feed Black & Decker Weed Eater

Follow these steps to reload a bump-feed model, which requires winding line onto a spool before inserting it into the head:

1. Press the release latch or button on the side of the trimmer head to remove the spool cover. If your model requires twisting, turn the cover counterclockwise until it releases.
2. Pull the empty spool out of the head. If the spool is stuck, gently wiggle it back and forth to loosen it without forcing it, which can damage the spool or head.
3. Cut a 10-12 foot length of replacement trimmer line in the correct diameter for your model (usually .065 or .080 inches for bump-feed units).
4. Insert one end of the line into the small hole on the center of the spool, then wind the line tightly around the spool in the direction indicated by the arrow printed on the spool (all Black & Decker spools have a directional arrow to show the correct winding direction). Wind 5-7 even, tight turns, leaving about 6 inches of line hanging out the end. Make sure the line is wound snugly against each turn to prevent tangling.
5. Thread the loose end of the line through the exit hole on the trimmer head, making sure it does not get caught on any sharp edges or debris.
6. Slide the spool back into the head, aligning the tabs on the spool with the slots in the head, then snap or twist the spool cover back into place until it clicks. Pull the loose end of the line firmly to test that it advances correctly when you tap the head on the ground.

Reloading a Fixed-Line Black & Decker Weed Eater

Fixed-line models are faster to reload, as most use pre-wound spools that you can drop directly into the head. Follow these steps for your fixed-line model:

1. Complete the pre-reload preparation steps above, making sure the tool is disconnected from power and the head is free of debris.
2. Locate the line release lever or knob on the side of the trimmer head. Turn it counterclockwise (or pull the lever out) to open the line compartment.
3. Remove any remaining pieces of old line from the head. If your model uses a pre-wound spool, pull the old spool out of the compartment and set it aside.
4. If your model uses individual line: cut two 10-foot lengths of the correct diameter line. Insert one end of each line into the anchor holes on opposite sides of the head, then pull the line taut so it is even on both sides. Trim the excess line so that 6 inches extend from each side of the head.
5. If your model uses pre-wound spools: drop the new pre-wound spool into the compartment, aligning the tabs on the spool with the slots in the head. Twist the release knob clockwise (or push the lever in) to lock it in place. Pull both ends of the line firmly to make sure they are secure and even.
6. Close the line compartment cover, making sure it clicks into place to prevent line from falling out during use.

Choosing the Right Trimmer Line for Your Device

Using the correct trimmer line is essential for optimal performance and to avoid damage to your weed eater. Most Black & Decker models use either .065 inch (1.65 mm) or .080 inch (2.0 mm) round trimmer line, though some heavy-duty fixed-line models support .095 inch (2.4 mm) line for cutting thick brush. .065 inch line is best for light grass and weeds, as it is lightweight and puts less strain on the motor. .080 inch line is better for thicker weeds and small brush, as it cuts more effectively without breaking. If you frequently cut dense vegetation, opting for a slightly thicker line (as long as your model supports it) will improve performance and reduce how often you need to reload.

While round line is standard for all Black & Decker weed eaters, some fixed-line models also accept square or hex-shaped line, which has sharper edges that cut through thick weeds more effectively. However, bump-feed models should only use round line, as shaped line causes excess wear on the centrifugal advance mechanism and can lead to premature failure of the trimmer head. Always check your user manual before switching to a non-standard line shape to confirm compatibility.

To help you choose the right line for your needs, refer to the comparison table below of the two main Black & Decker weed eater types:

Tips for Longer Line Life and Better Performance

Reloading your weed eater correctly is only half the battle – following these best practices will help your line last longer and improve cutting performance between reloads:

• Store extra line in a dry, cool place: Exposure to sunlight and moisture can make trimmer line brittle, leading to frequent breakage. Keep spare line in a sealed container in your garage or shed to preserve its flexibility.
• Wind the line tightly on the spool: Loose winding causes the line to tangle when you advance it, leading to uneven cutting and frequent jams. Make sure each turn of line is snug against the previous one when loading a bump-feed spool.
• Avoid bumping the trimmer head on concrete or rocks: Bump-feed models rely on a centrifugal mechanism that releases line when the head is tapped on a soft surface like grass. Bumping it on hard surfaces can damage the mechanism and break the line prematurely.
• Cut line to the correct length after reloading: Most Black & Decker weed eaters perform best with 6-8 inches of line extending from the head. Longer line puts excess strain on the motor and causes more drag, while shorter line won’t cut effectively.
• Clean the trimmer head regularly: Grass clippings and dirt can build up in the spool compartment, causing the line to jam or advance unevenly. Wipe the head down after every 2-3 uses to keep it functioning smoothly, and use a small brush to remove debris from hard-to-reach areas.
• Use sharp, high-quality line: Cheap, low-quality trimmer line is often made from brittle plastic that breaks easily, even when used correctly. Invest in reputable brand line to reduce breakage and improve cutting performance.

Common Mistakes to Avoid When Reloading

Even experienced weed eater owners make these common reload mistakes, which can lead to poor performance, frequent breakage, or damage to the tool. Avoid these errors to make reloading faster and easier: (See Also:Which Way To Wind Weed Eater String)

• Using the wrong line diameter: Using line that is too thick will make it impossible to close the spool cover, while line that is too thin will slip and break constantly. Always check your user manual for the exact recommended size before buying replacement line.
• Winding the line in the wrong direction: Almost all bump-feed spools have an arrow indicating the correct winding direction. Winding the line backward will cause it to tangle when you try to advance it, and you’ll have to unload and rewind the entire spool.
• Overfilling the spool: It can be tempting to add as much line as possible to avoid reloading for as long as possible, but overfilling the spool prevents the cover from closing properly and causes the line to jam. Follow the line capacity markings on the spool, or wind 5-7 turns for bump-feed models as a general rule.
• Skipping the safety step of disconnecting power: It’s easy to forget to unplug the tool or remove the battery before opening the head, but accidental startup can cause serious cuts to your hands or fingers. Always disconnect power first, no matter how experienced you are with reloading.
• Forcing the spool cover closed: If the cover won’t snap or twist into place, don’t force it. This usually means the line is wound incorrectly, the spool is overfilled, or the line is stuck in the exit hole. Double-check your work before applying pressure, which can break the cover or damage the head.
• Using dull or old line: Even if trimmer line hasn’t broken, it becomes dull and brittle over time, especially if it’s been exposed to sunlight. Replace your line regularly, as dull line puts excess strain on the motor and cuts poorly.

Troubleshooting Common Post-Reload Issues

If you run into problems after reloading your weed eater, you don’t always need to take it to a repair shop. Most common post-reload issues have simple fixes you can do at home:

• Line won’t advance when you tap the head (bump-feed models): First, confirm you wound the line in the correct direction by checking the arrow on the spool. If that’s correct, check that the line is threaded through the exit hole properly, and that there are no kinks or tangles in the line. If the problem persists, the centrifugal mechanism in the head may be damaged, and you may need to replace the trimmer head.
• Line breaks repeatedly immediately after reloading: This is usually caused by using the wrong line diameter, winding the line too loosely, or having sharp burrs or debris in the trimmer head. Check that you’re using the correct line size for your model, wind it tightly and evenly, and wipe down the inside of the spool compartment to remove any sharp debris that could be cutting the line.
• Line feeds out too far or too little: Adjust the line length by pulling the loose end to the desired 6-8 inch length and trimming off any excess with a pair of scissors or the built-in cutter on your trimmer head. For fixed-line models, use the adjustment knob on the side of the head to set the correct length.
• Trimmer head vibrates excessively after reloading: This is almost always caused by an unevenly wound spool, or a spool that is not seated properly in the head. Unload the spool, rewind it tightly and evenly, then reinsert it making sure the tabs on the spool align perfectly with the slots in the head.
• Line feeds out continuously even when not in use: This is usually caused by a damaged centrifugal mechanism in the trimmer head, or a spool that is not seated properly. First, remove the spool and reinsert it, making sure the tabs are aligned with the slots. If the problem persists, the mechanism may be broken, and you will need to replace the trimmer head.

Frequently Asked Questions

How often should I reload my Black & Decker weed eater?

The reload frequency depends on how often you use the tool and the type of weeds you’re cutting. For light residential use (trimming grass around sidewalks and garden beds once a week), you’ll likely need to reload every 2-3 uses. If you’re cutting thick, overgrown weeds or woody brush, you may need to reload after every 1-2 hours of continuous use. Bump-feed models typically require more frequent reloads than fixed-line models, as the line wears down faster from contact with the ground when advancing.

Can I use third-party trimmer line in my Black & Decker weed eater?

Yes, you can use third-party trimmer line as long as it matches the diameter and shape recommended for your specific model. Black & Decker’s OEM line is high-quality, but many reputable third-party brands offer the same performance at a lower cost. Just avoid cheap, unbranded line, as it is often made from low-quality plastic that breaks easily and can damage your trimmer head.

Why does my line keep breaking right after reloading?

Recurring line breakage after reloading is almost always caused by one of three issues: using the wrong line diameter for your model, winding the line too loosely on the spool, or having sharp burrs or debris in the trimmer head. First, confirm you’re using the correct line size for your model, then make sure you wind the line tightly and evenly. Wipe down the inside of the trimmer head with a cloth to remove any burrs or sharp debris that could be cutting the line as it advances.

What is the difference between bump-feed and fixed-line models?

Bump-feed weed eaters advance the trimmer line automatically when you tap the bottom of the head on the ground, making them convenient for quick adjustments during use. Fixed-line models require you to manually adjust the line length via a knob or lever on the head, but they are less prone to accidental line breakage and typically require less frequent reloads. The reload process also differs: bump-feed models require you to wind line onto a spool, while most fixed-line models use pre-wound spools that you can drop directly into the head for fast reloading.

How do I know if my weed eater uses bump-feed or fixed-line?

The easiest way to tell is to look at the bottom of the trimmer head. Bump-feed heads have a small, rounded bottom with no visible line adjustment mechanism, and you advance the line by tapping this bottom on the ground. Fixed-line heads have a small knob, lever, or sliding mechanism on the side or bottom that you use to adjust the line length manually. You can also check your user manual, which will clearly state which type of feed system your model uses.
