Step One: Preparing the Trimmer for Spooling

Before beginning, make sure that the trimmer is properly assembled and that all parts are in good working order. If the trimmer is new, it will come with a spool of line already installed. If you are rewinding an old spool or one that has been damaged, you’ll need to remove the old line and dispose of it properly.

To remove the old line, first disconnect the trimmer from its power source. Remove the spool cap from the trimmer head, being careful not to lose any of the small parts or hardware. With the cap removed, you should be able to see the spool of line. Carefully unwind any remaining line from the spool and discard it.

Step Two: Inserting the New Spool

With the new spool in hand, place it on the trimmer with the label facing up. Depending on your model, there may be a retainer clip or other locking mechanism that needs to be removed before you can proceed. With the spool in place, insert the line into the eyelet hole in the center of the spool. If your spool has a stake in the center, make sure that the line is wrapped around it so that it will feed correctly.

Step Three: Securing the New Spool

To secure the new spool, first thread the end of the line through the eyelet on the bottom of the spool, then pull it tight. Next, wrap the line around the spool a few times, then thread it through the second eyelet and pull it tight. Finally, wrap the line around the spool a few more times and trim off any excess.

Step Four: Testing the New Spool

Now that the new spool is in place, you’ll need to test it out to make sure it’s feeding properly. To do this, you’ll need to put the trimmer back together and turn it on. Start by feed a small amount of line through the eyelet and holding it in place with your finger. Then, turn on the trimmer and let it run for a few seconds. If the line is fed smoothly, then you’re all set! If not, you may need to adjust the tension knob located on the spool housing until the line feeds properly.


In conclusion, whether you are looking to replace a old and worn out spool or you are just getting started with your Black and Decker trimmer, this guide should help you get the job done quickly and easily. With just a few household items and a little bit of time, you can have your trimmer up and running like new again in no time.
