How To Keep String Trimmer Line From Sticking

String trimmer line can easily get tangled up, making it difficult to use. In this article, we’ll show you a few easy steps to keeping your string trimmer line from sticking.

Check the line tension

If your string trimmer line is sticking, one common cause is that the line tension is too high. To check line tension, run the string over a metal fence (or another straight edge) and see if it leaves an imprint. If the line is too tight, it will leave an indent in the metal.

To adjust line tension, first make sure that the barbs on the line are fully extended by gently pushing down on each barb with your fingers. Then, use the included adjusting screw to tighten or loosen the line. Be sure to re-check the line tension after making any adjustments in order to ensure that it remains stable.

Keep the blade sharp

Keeping the blade sharp is key to keeping string trimmer line from sticking. Dull blades will not cut the string as cleanly, which can lead to clogging and jamming. To keep your blade sharp, follow these tips:


  1. Clean the blade regularly – Remove debris and dirt build-up with a soft cloth or a brush. This will keep the blade finely honed and reduce the chance of it becoming dull.
  2. Sharpen the blade regularly – If you notice that your blade is becoming dull, take it to a professional who can sharpen it for you. A sharp blade will cut through the string more easily, preventing clogging and jamming.
  3. Use the appropriate cutting length – A longer cutting length will let you effortlessly trim tall grass and other dense vegetation, while a shorter length is best for delicate plants or smaller branches.
  4. Apply pressure when cutting – Keep your hand close to the blade when cutting, applying slight pressure so that the blade slices through the string cleanly and quickly.

Change the oil and sharpen the blade regularly

Keeping your string trimmer line free of stickiness can be a challenge, but it’s important to remember to change the oil regularly and sharpen the blade. Here are some tips on how to keep your string trimmer in good working order:


  1. Change the oil every season or when you notice a decrease in power.


  1. Sharpen the blade regularly with a sharp blade sharpener. Use a moderate amount of pressure when sharpening to avoid nicking the blade.

Don’t overleafar

When using a string trimmer, it’s important to keep the line from sticking to the blades. If the line is too thick, it will cause resistance when cutting. This can lead to fatigue and ultimately, a faulty trimmer.


To avoid this issue, make sure that the string is thin enough to move freely through the blades. Additionally, overleafar (cutting the string beyond the blade) will help break up any clumps and prevent it from sticking.


If you find that your string trimmer line is constantly sticking to the cutting head, there are a few things that you can do to remedy the situation. First, make sure that the blade is sharp and free of debris. Next, test the line by slowly moving the trimmer across an empty piece of paper. If the string doesn’t pull tight against the paper, then it needs a new cutting head. Finally, try spraying some WD-40 or other lubricant onto the blade and around the wheel bearings; this will help reduce friction and keep your line from sticking.
