The website that everyone enjoys viewing “National Safety Center” ? Probably not many people check it out.
Recently, on August 21, 2024, the latest grass trimming information was updated.
Be careful of accidents while operating a brush cutter (grass trimmer)!
While I think fewer people use engine-powered grass trimmers these days, the basic precautions remain the same.
When accidents happen, people suffer serious injuries they regret for the rest of their lives or cause harm to others.
Since the season is approaching, I think the National Safety Center updated their information for this reason.
I hope you can safely enjoy grass trimming (*´ω`*)
If you want to see a rough overview in video form, here it is.
It flies! Important points about kickback.


When cutting grass, use only the left side. Swing from right to left! As shown in the image, use the left front third.


Don’t use both right and left sides in a back-and-forth cutting motion. Kickback will occur, so please don’t do it.


Also be careful about full-swing cutting to increase the amount of grass cut.
If large stones or hard objects are lying in the grass, they can get caught and cause kickback.
I think the key to avoiding serious injury is to work gently, without forcing it, and without rushing.
It flies! Here’s how the kickback principle works



When you enter the red zone, the grass trimmer is more likely to be thrown.
The force is so instantaneous that you can’t react in time.
If it hits someone or yourself, you’ll suffer an unbelievably serious injury, so absolutely don’t do it.


Looking at it this way, the difference between safe and unsafe areas is razor-thin.
If you get overconfident, you can easily enter the kickback zone, so please be careful.
Clearing clogged grass and removing rolling objects is dangerous.


This is a symptom that wouldn’t occur with anything other than engine-powered models, but it’s still best to turn off battery-powered ones just to be safe.
Don’t be lazy about just a few tens of seconds
and burden the rest of your life with a handicap.
Serious injuries often happen when people think it’s a bit of a hassle, so please turn off the power.


This is an experiment showing how far small stones can fly.
The shocking result: they flew up to 54 meters. In other words, they’re being ejected with incredible force.
If one hits your eye, you’ll definitely go blind; if it hits a car, the glass will easily shatter.
Approach it with the same caution as “fire prevention, fire prevention, fire prevention.”




When using nylon cord, please be careful as well.
It can fly up to about 15 meters. It will easily break house windows.
Don’t underestimate it just because it’s nylon cord; be careful to ensure there are no objects or people nearby when using it.

While it may not be practical when working alone, it’s safer not to work in areas that seem dangerous.
The content posted by “National Consumer Affairs Center” is extremely interesting and educational.
In today’s world, tools are easily accessible and work can be done conveniently.
Imagine your own hands and feet being cut
and being a little nervous is the right level of caution.
If you search, you’ll find some pretty gruesome images, so I recommend checking them out.
