My number one rule on chainsaw safety is not to put gas in it. I’ve used and misued tools that would seem much more dangerous but I won’t touch one.
I used a chainsaw for many years on my rural property.
As with anything else, proper gear and proper training are the key.
If you pay attention to detail and stop working when you start getting tired it is not that bad.
I had no incidents—not even a close call—and I cut down many large trees.
