Replace Trimmer Strings in 7 Steps

Ready to create the perfectly finished yard? It’s hard to do without the right string trimmer. Trimmers create clean and clear edges around flower beds, walkways, driveways and more, which are essential components of a tidy yard.

If you’ve used a string trimmer regularly, you know that from time-to-time you need to replace the trimmer line if it’s damaged or runs out. Fortunately, it’s easy and quick to do, so you can get back to finishing the job.

Here are 7 simple trimmer line replacement steps:

Before working on your string trimmer or any outdoor power equipment, read your operator’s manual for safety instructions, directions, product requirements and tips. Remember to also always dress for the job whenever you operate or work on outdoor power equipment by wearing close-toe shoes, long pants and hearing and eye protection.

  1. Purchase trimmer line specific to your string trimmer. Replacement line ranges from 0.065 inches to 0.095 inches and improper size will damage your trimmer.
  2. Check that the engine is off and cool.
  3. Cut trimmer line to an appropriate length for your string trimmer. Often this is between 15 and 25 feet long, depending on your spool size.
  4. Remove the spool cover cap from the trimmer head by unscrewing or pressing tabs.
  5. Insert one end of the trimmer line in the starter hole and wind clockwise, or in the direction your trimmer designates. SF Gate recommends winding onto the spool side to side before overlapping to prevent tangles.
  6. Secure the last five to six inches of trimmer line on the spool edge notch and feed the loose ends through the line exit hole.
  7. Reattach the spool head and check your guard. A sturdy guard protects you from debris while the tool is in use.

Now that you’ve replaced you trimmer strings, you’re ready to add the finishing touches to your yard!
