Never use a chainsaw without any protective gear to avoid accidental injuries.
You can’t cut with the saw until you unlock the chain brake.
Pushing against the wood could cause the chainsaw to kickback or the blade to get stuck.
It’s also important that you keep your chainsaw properly maintained. Clear away dirt and debris from the chainsaw’s teeth and make sure it has plenty of oil.
If someone is a beginner, keep an eye on them and make sure they’re using the chainsaw safely.
If the tree is already leaning in 1 direction, cut it down so it falls that way.
The notch creates a hinge and will direct which way the tree falls.
Make sure anybody in the area moves out of the way of the falling tree.
If you can’t reach it, don’t try to cut it with a chainsaw!
