Tools and Materials You’ll Need
Before you start the respooling process, gather all the necessary supplies to avoid interruptions. Having everything on hand will make the process fast and efficient, especially if you’re working on multiple weed eaters or need to finish yard work quickly. You will need:
- Replacement trimmer line (correct diameter for your model, see Section 4 for how to confirm)
- Clean rags or paper towels
- Isopropyl alcohol (optional, for cleaning the spool head)
- Small flathead screwdriver or spool release tool (most Black & Decker models include this with the original purchase)
- Scissors or line cutter
- Work gloves (optional, to protect your hands from sharp line edges)
Most of these items are already in your standard tool kit, and replacement trimmer line is available at any hardware store, home improvement center, or online retailer for a fraction of the cost of a full pre-loaded replacement spool.
How Black & Decker Weed Eater Spool Systems Work
Black & Decker weed eaters use a bump-feed or automatic-feed spool system designed to release a consistent length of trimmer line with each bump of the head against the ground. The spool is housed in a plastic or metal head at the bottom of the weed eater, and the line is wound around a central spool hub, with both ends fed through small exit holes in the head. When the head bumps the ground, a spring-loaded mechanism releases a small amount of line (usually 2-3 inches) to maintain cutting length as the line wears down during use.
Most Black & Decker models use a single-line spool system, though some larger commercial-grade models use a dual-line spool for increased cutting width. The respooling process is nearly identical for both single and dual-line models, with the only difference being the amount of line you load and the number of exit holes you thread the line through. Understanding how your spool system works will help you avoid common errors like winding the line in the wrong direction, which is the most common cause of post-respooling jams and tangles.
Identifying Your Specific Black & Decker Model
Black & Decker produces dozens of weed eater models, each with slightly different spool sizes, line thickness requirements, and loading mechanisms. Before you buy replacement line or start respooling, confirm your model number to ensure you purchase compatible supplies. You can find the model number printed on a sticker on the bottom of the weed eater head, on the tool’s body near the handle, or in the original user manual.
Common Black & Decker weed eater model lines include the String Trimmer 20V MAX, the 40V MAX, the Corded Grass Hog, and the lightweight LE series. Each of these lines has specific line diameter requirements: most residential models use 0.065-inch line, while heavier-duty models use 0.080-inch line. Using the wrong line thickness can cause jams, poor cutting performance, and damage to the spool mechanism. If you’re unsure of your model’s requirements, check the user manual or the label on the old spool you’re replacing for the recommended line size.
Step-by-Step Guide to Respooling a Black & Decker Weed Eater
Now that you have your supplies and know your model’s requirements, follow these steps to respool your Black & Decker weed eater quickly and correctly. This process works for nearly all Black & Decker bump-feed and automatic-feed models, and takes 5-10 minutes to complete.
- Disconnect power to the tool first. For corded models, unplug the weed eater from the outlet. For cordless models, remove the battery pack. This prevents accidental startup while working on the spool, avoiding serious injury.
- Remove the old spool. Press and hold the spool release tab on the bottom of the head, then twist the spool housing counterclockwise to remove it. Pull the old spool out and set the housing aside.
- Clean the housing and head. Wipe away grass clippings, dirt, and old line debris with a clean rag. Use isopropyl alcohol for stuck-on grime to prevent new line from jamming.
- Prepare new trimmer line. Cut a 10–15 foot length of line (20–25 feet for dual-line models) matching your model’s required diameter. Smooth any rough cut edges with scissors to prevent snags.
- Wind the line around the spool hub. Wind the line tightly and evenly in the clockwise direction (check the arrow printed on the spool hub for confirmation). Leave 4–6 inches of line at the end, and do not overfill: keep a 1/4-inch gap between the wound line and the spool edge.
- Thread the line through exit holes. Insert the loose line end into the spool’s exit hole, pulling 2–3 inches through. For dual-line spools, repeat with the second line length on the opposite side.
- Secure the line. Tuck the loose end into the notch on the spool edge to hold it in place during loading.
- Load the spool into the head. Align the spool hub with the housing opening, push until it clicks, and pull the line ends through the head’s exit holes.
- Reattach the housing. Align the housing tabs with the head slots, twist clockwise until it clicks, and press the release tab to confirm it is locked.
- Test the feed. Reconnect power, turn on the tool, and bump the head 2–3 times. If 2–3 inches of line releases per bump, the respooling is successful. If not, check the winding direction and spool lock.
How to Load Different Line Types
Black & Decker weed eaters work with several types of trimmer line, each designed for different cutting conditions. The most common line types are round, square, and serrated. Round line is the standard for residential use, and works well for light grass and weeds. Square line has a sharper edge that cuts thicker weeds and woody vegetation more effectively. Serrated line is designed for heavy-duty use, and cuts through dense brush and overgrown grass with minimal effort.
When loading different line types, the respooling process is identical, but you may need to adjust the amount of line you wind onto the spool. Thicker serrated line has a lower capacity than thin round line, so you will need to wind fewer feet of line to avoid overfilling the spool. Always check your model’s manual for the maximum line thickness it can accommodate to avoid damaging the feed mechanism.
Tips for Fast, Tangle-Free Respooling
Once you master the basic respooling process, you can cut your time in half and avoid frustrating tangles with these simple tips. These tricks are especially useful if you respool your weed eater frequently, or if you need to finish yard work quickly after your line runs out.
- Pre-wind spare spools at home: Keep 2-3 pre-loaded spools in your garage or tool box. When your line runs out mid-job, you can swap the empty spool for a full one in 30 seconds, no respooling required.
- Wind line tightly and evenly: Loose, unevenly wound line is the top cause of jams and tangles. Use a firm, consistent motion when winding line around the spool hub to keep it tight and uniform.
- Mark the correct winding direction on the spool: If your spool doesn’t have a printed arrow indicating the winding direction, use a permanent marker to draw a clockwise arrow on the side of the spool. This eliminates guesswork every time you respool.
- Don’t overfill the spool: Leave a 1/4-inch gap between the wound line and the edge of the spool. Overfilling causes line to bunch up and jam in the feed mechanism.
- Use a line winder tool for faster winding: Inexpensive line winder tools attach to the spool hub and hold the line in place while you turn the handle, cutting winding time in half and ensuring even tension.
Comparison of OEM vs. Third-Party Replacement Spools
When respooling your Black & Decker weed eater, you can choose between original equipment manufacturer (OEM) Black & Decker spools and universal third-party replacement spools. Both options work well, but there are key differences to consider when making your choice. The table below compares the two options across key features to help you decide which is right for you.
| Feature | OEM Black & Decker Spool | Universal Third-Party Spool |
|---|---|---|
| Compatibility | Guaranteed to fit your specific Black & Decker model, no adjustments needed | Fits most common Black & Decker models, but may require minor trimming or adjustment for older or less common models |
| Material | High-grade, impact-resistant plastic designed to match the durability of the original tool | Varies by brand; most use durable plastic, but lower-quality options may crack or break faster |
| Price | $8–$15 per spool | $3–$8 per spool |
| Line Capacity | Matches original line capacity for your model | May have slightly higher or lower capacity depending on the brand |
| Lifespan | 1–2 years with regular use | 6 months to 2 years, depending on quality |
| Ease of Loading | Designed for tool-free, click-in loading | Most are tool-free, but some may require minor adjustments to fit properly |
For most casual users, universal third-party spools are a cost-effective option that works just as well as OEM spools. If you use your weed eater frequently for commercial landscaping or heavy-duty yard work, OEM spools may offer better long-term durability and guaranteed compatibility.
Common Respooling Mistakes and How to Avoid Them
Even experienced weed eater users make mistakes when respooling, leading to jams, poor cutting performance, and even damage to the tool. Avoid these common errors to make your respooling process smooth and trouble-free:
- Winding the line in the wrong direction: This is the most common mistake, and it causes the line to jam and not feed properly when you bump the head. Always check the arrow on the spool hub or your model’s manual to confirm the correct winding direction before you start.
- Overfilling the spool: Packing too much line onto the spool leaves no room for the line to move freely, causing it to bunch up and jam. Always leave a 1/4-inch gap between the wound line and the edge of the spool.
- Using the wrong line thickness: Line that is too thick will not fit through the exit holes or feed properly, while line that is too thin will wear out quickly and not cut effectively. Always check your model’s recommended line size before purchasing replacement line.
- Skipping the cleaning step: Grass clippings and dirt left in the spool housing can cause new line to get stuck or jam. Always wipe out the housing before loading a new spool.
- Not securing the spool properly: If the spool is not locked into place, it will wobble during use, causing the line to tangle and break. Always twist the spool housing until it clicks into place, and press the release tab to confirm it is secure.
Maintaining Your Weed Eater to Extend Spool Life
Proper maintenance of your Black & Decker weed eater will extend the life of your spool and reduce how often you need to respool. Follow these simple maintenance tips to keep your tool running smoothly:
- Clean the spool head and housing after every 2-3 uses to remove grass clippings and dirt that can cause jams.
- Wipe down the trimmer line after each use to remove sap and debris that can cause the line to stick together and tangle.
- Store your weed eater in a dry, cool place to prevent the plastic spool from becoming brittle and cracking in extreme temperatures.
- Inspect the spool and feed mechanism every month for signs of wear or damage. Replace the spool if you notice cracks, broken tabs, or worn feed mechanisms.
- Use the correct line thickness for your model to avoid putting excess strain on the spool and feed mechanism.
Troubleshooting Common Post-Respooling Issues
Even when you follow the respooling process correctly, you may encounter issues with line feed or cutting performance. Here are solutions to the most common post-respooling problems:
- Line does not feed when you bump the head: Check that you wound the line in the correct direction, that the spool is locked securely in place, and that there is no debris blocking the exit holes. If the problem persists, the feed mechanism spring may be broken and need replacement.
- Line jams frequently: This is usually caused by overfilling the spool, winding the line loosely, or using line that is too thick for your model. Unwind the spool, remove excess line, and reload with the correct amount of line wound tightly.
- Line breaks constantly during use: This may be caused by dull blades on the weed eater head, using line that is too thin for the vegetation you’re cutting, or a damaged spool that is causing the line to snag. Sharpen or replace the head blades, use a heavier line thickness, or replace the spool if it is damaged.
- Line feeds too much or too little with each bump: Adjust the line feed dial on the head (if your model has one) to control the amount of line released with each bump. If your model does not have an adjustable dial, you may need to replace the feed mechanism spring to adjust the feed length.
Frequently Asked Questions
How often should I respool my Black & Decker weed eater?
The frequency of respooling depends on how often you use your weed eater and the type of vegetation you cut. For casual residential use (1-2 times per month), you will likely need to respool every 2-3 months. For frequent use or heavy-duty cutting of thick weeds and brush, you may need to respool every 1-2 weeks. Inspect your line before each use, and respool when the line is worn down to less than 2 inches long, or if it is frayed or broken.
Can I use any brand of trimmer line on my Black & Decker?
Yes, you can use any brand of trimmer line as long as it matches the diameter requirement for your specific Black & Decker model. Most residential models use 0.065-inch line, while heavier-duty models use 0.080-inch line. Avoid using line thicker than the recommended size, as it can damage the feed mechanism and cause jams. Third-party line is often cheaper than OEM Black & Decker line, and works just as well for most users.
Why does my line keep jamming after respooling?
Line jams after respooling are almost always caused by one of three issues: winding the line in the wrong direction, overfilling the spool, or leaving debris in the spool housing. Double-check that you wound the line clockwise (the correct direction for most Black & Decker models), leave a 1/4-inch gap between the line and the spool edge, and clean the housing thoroughly before loading a new spool. If jams persist, check that you are using the correct line thickness for your model.
How do I know what line size my Black & Decker weed eater uses?
You can find the recommended line size for your model in three places: the user manual that came with your weed eater, the label printed on the bottom of the spool head, or the label on the old spool you are replacing. If you cannot find this information, you can also look up your model number on the Black & Decker website to find the specifications. Never guess the line size, as using the wrong thickness can damage your tool.
Is it cheaper to respool or buy a new pre-loaded spool each time?
Respooling is almost always cheaper than buying a new pre-loaded spool. A pre-loaded OEM Black & Decker spool costs $8–$15, while a spool of replacement trimmer line costs $3–$6 and can be used to respool 3-5 times before the line wears out. Over the course of a year, respooling can save you $50 or more, depending on how often you use your weed eater. Third-party pre-loaded spools are cheaper than OEM, but still cost more than buying bulk line and respooling yourself. If you’re still wondering How to Respool Black and Decker Weed Eater? to get the most savings, follow the step-by-step guide above for the best results.
