Rewinding a Black and Decker String Trimmer: A Step-by-Step Guide
If you're a homeowner or gardening enthusiast, you know the convenience and efficiency of a Black and Decker string trimmer. However, like any tool, the line can wear out and need replacing. Here's a comprehensive guide on how to rewind a Black and Decker string trimmer, ensuring it's always ready for your trimming needs.
Understanding Your Black and Decker String Trimmer
Before we dive into the rewinding process, let's understand the basic components of your Black and Decker string trimmer. The trimmer head is where the line is housed and dispensed. It's usually located at the bottom of the trimmer, near the cutting area. The line is typically made of nylon and comes in various sizes, with 0.065" and 0.080" being common for Black and Decker trimmers.
Preparation: Gather Your Tools and Materials
Before you start, ensure you have the following tools and materials:

- New trimmer line (matching the size of your current line)
- Scissors or line cutter tool
- Screwdriver (if your trimmer head requires it)
- Gloves (optional, for safety)
Step-by-Step: Rewinding Your Black and Decker String Trimmer
Step 1: Disassembly
Start by unplugging your string trimmer from the power source. Then, remove any remaining line from the trimmer head. If your trimmer head is held in place by a screw, use a screwdriver to remove it. Some trimmer heads may have a release button or may simply unscrew counterclockwise.
Step 2: Measure and Cut the New Line
Measure the length of line needed. For most Black and Decker trimmers, this is around 16 to 20 feet. Cut the new line to this length using scissors or a line cutter tool. Make sure the line is cut square to ensure it feeds evenly.
Step 3: Thread the Line
Find the eyelet or hole in the trimmer head where the line will be inserted. Thread one end of the line through this hole. Leave a small tail of line (around 6 to 8 inches) hanging out of the eyelet.

Step 4: Wind the Line
Wrap the line around the spool in the direction indicated by the arrow on the spool. Ensure the line is wound evenly and tightly against the spool. Leave a small amount of line (around 6 to 8 inches) unwound at the end.
Step 5: Reassemble the Trimmer Head
Once the line is wound, reattach the trimmer head to the trimmer. If your trimmer head has a screw, tighten it securely but be careful not to overtighten. If your trimmer head has a release button, make sure it's properly engaged.
Step 6: Test the Trimmer
Plug in your string trimmer and test it. The line should feed out automatically as you pull the trigger. If it doesn't, you may need to adjust the line or check your work.
Troubleshooting Common Issues
If your line isn't feeding properly, here are a few common issues and their solutions:
| Issue | Solution |
|---|---|
| Line isn't feeding at all. | Check that the line is wound in the correct direction. Also, ensure that the trimmer head is properly attached and the release button is engaged. |
| Line is feeding too slowly. | Check that the line is wound tightly and evenly. Also, ensure that the line isn't too long; trimming it shorter may help. |
| Line is feeding too quickly. | Check that the line isn't too short. Also, ensure that the line is wound loosely enough; unwinding it a bit may help. |
Regularly rewinding your Black and Decker string trimmer ensures it's always ready for use and helps prolong the life of the tool. With this guide, you're equipped to handle this maintenance task like a pro. Happy trimming!
