String trimmers can be dangerous when used incorrectly. They can cut your feet when the string is too close to your feet and they can hurt your back when you’re mowing with a hunched back instead of maintaining a straight back position.

5 Common Mistakes that Make String Trimmers Dangerous

Trimmers aren’t too dangerous or more dangerous than other power tools. However, the following mistakes make them very dangerous.

  1. Not wearing safety glasses

Not wearing safety glasses is the primary concern with string trimmers. They are known for throwing rocks and small objects encountered on the lawn a few feet into the air at high speed. To avoid having any problems you need to wear safety glasses which aren’t expensive, but which can save you a lot of trouble when it comes to vision.

  1. Not wearing safety earmuffs

Wearing earmuffs should be mandatory when using string trimmers. Load and made with engines that vibrate a lot, string trimmers can damage your hearing in the long term and give you a headache in the short term. Mowing the lawn with a string trimmer in high heat without wearing safety earmuffs is a recipe for a strong headache.

  1. Not standing upright

Back pain while using a string trimmer is very common. These are attached to your back with a special harness. If the height of the attachment point isn’t correct it favors hunching over. This leads to upper back pain. To avoid this issue make sure you stand out all the time while using the string trimmer or get a better harness for upright positioning.

  1. Removing the edge guide

Removing the edge guide is one of the main reasons for hurting trees with a string trimmer. This is why you should double-check the edge guard is installed when mowing the lawn. Some string trimmers don’t have an edge guard. You should replace these and look for string trimmers that can protect your trees.

  1. Removing the trimmer guard from the trimmer head

If you remove the trimmer guard you’re up for a large series of potential injuries. There’s nothing stopping small rocks from flying towards you when the trimmer guard is removed. While some tutorials and string trimmers reviews show us how the best string trimmers work they fail to mention dangers associated with removing the trimmer guard.

String trimmer safety tips

While these are common mistakes users can make when it comes to wrongly using string trimmers there are more steps to consider for complete safety. As with lawnmowers, string trimmers can be as dangerous as possible when you have no safety concerns. Here’s what you can do to go beyond what manufacturers tell you.

  • Wear steel toe boots when mowing the lawn

Steel toe boots are your best friend when it comes to preventing the string trimmer from cutting your feet. Some string trimmers using a metal string are so strong they can cut through shoes. This is why you need to be careful about which of the work boots you like are going to protect your feet best. One of the only true protective solutions is steel toe shoes or steel toe boots.

  • Take frequent breaks to avoid extreme fatigue

Another common issue with power tool injuries is extreme fatigue. Unlike using a small cordless drill string trimmers put a lot of pressure on your back and on your hands. This means you will need to take breaks. While design for small lawns and areas that are hard to reach with a lawnmower, most string trimmers are still used on large lawns.

You should learn to take frequent breaks even when working on small lawns. Lawn mowing breaks when using a string trimmer should take place every 10 – 15 minutes. You place the string trimmer down and you remove the protective safety earmuffs during the 2-3 minute break.

  • Wear protective gloves

Protective gloves aren’t a must for string trimmers. But they’re nice to have. One of the biggest reasons to wear padded protective work gloves is to limit the vibrations your hands have to deal with. A lot of vibrations to your hands can lead to Raynaud’s disease. This can be described as the feeling of vibration in your fingers even when you’ve stopped using the trimmer and when you aren’t even holding it.

Make sure you take string trimmers and all other power tools seriously. Why we all love our homes at we also want to stay safe and healthy to enjoy them as long as possible.
