Assuming you have a Craftsman trimmer with the company’s trademarked “Autofeed” system, replacing the trimmer line is a relatively easy process. You’ll need to start by removing the spool of old line, and then installing the new spool. The Autofeed system will automatically feed out new line as needed, so you won’t have to worry about winding it manually.

What You’ll Need

-A new spool of trimmer line
1. Unplug the trimmer from the outlet.
2. Remove the old spool of trimmer line from the trimmer. To do this, you will need to first remove the spool cap, and then pull the spool out of the housing.
3. Cut off a length of trimmer line that is about 20 feet long.
4. Feed one end of the new trimmer line through the hole in the center of the spool, and then tie it off so that it is secure.
5. Wrap the new trimmer line around the spool in a clockwise direction until there is no more slack in the line. Make sure that you do not wrap the line too tightly, or it will be difficult to feed through the head when you are ready to use it.
6. Once you have finished wrapping the new line around the spool, insert it back into the housing, and then replace the spool cap.
7. Plug in the weedwacker, and you are ready to go!

Step One: Prep the Trimmer

Before you replace the trimmer line on your Craftsman weedwacker, you need to prep the trimmer. This involves a few simple steps:

-Remove the spool of line from the trimmer by unscrewing the knob at the top of the spool.
-Cut off any remaining line from the spool with a pair of scissors.
-Wind the new line around the spool in the direction indicated by the arrow on the spool. Make sure that you wind it tightly so that it doesn’t come loose when you’re using the trimmer.
-Screw the knob back onto the top of the spool.

Step Two: Remove the Spool

To remove the spool, first unscrew the bump knob at the top of the weedwacker. Once the knob is removed, you’ll be able to see the spool. Pull on the spool until it comes free from the housing.

Step Three: Cut and Attach the New Line

Attach the new trimmer line to the spool. For pre-wound spools, hold the line at the end of the spool and pull it tight. Push the end of the line through one of theempty holes in the spool until it pops out the other side. Continue doing this until you have 6 to 8 inches of line extending from the spool. If you are using a new, replacement spool, cut a length of new trimmer line that is long enough to fit aroundthe circumference of the spool. Feed one end of the trimmer line through on empty slot in th ecenter hub ofthe spool. Wrap it around several times, making sure that each wrap is snug againstthe one before it. When you have wrapped it around five or six times, feed he other end through
a different empty slot in th center hub so thatit crosses overthe first pieceofline. Again, wrapitaroundseveral times, makingeachwrap snug againsttheonebeforeit.

Step Four: Reassemble the Trimmer

Now that you have your new trimmer line, it’s time to reassemble the trimmer. Start by gently pushing the spool back into the trimmer head. Make sure that the spool is seated correctly in the head, and then screw on the retainer clockwise until it is tight.


In conclusion, replacing the trimmer line on a Craftsman weedwacker is a very easy process. You will need to locate the correct size line for your model of weedwacker, and then simply wind it around the spool in the correct direction. Be sure to keep an eye on the tension of the line as you go, and don’t hesitate to ask for help if you get stuck. With a little practice, you’ll be able to replace your trimmer line in no time!
