Why does my chainsaw chain keep loosening?

What happens if a chainsaw chain is too loose?
A loose chainsaw chain increases the risk of kickback as well as the chances of the saw chain being thrown off the guide bar. Saw chain that is too tight can prevent the chainsaw from turning the saw chain or cause the chainsaw to heat up.
How often should you tighten chainsaw chain?
The chain isn’t actually becoming tighter—instead, as you turn the tensioning pin—it pushes the chainsaw bar out a little bit, which takes up the slack on the chain. During a typical afternoon wood-cutting session that lasts 2 to 4 hours, you may need to tighten the chain two or three times.

There is a tension screw located near the base of the bar on the chainsaw. To tighten the chain, turn it clockwise, and to loosen turn it counterclockwise. Don’t over-tighten the chain as this could cause it to break.
How much tension should a chainsaw blade have?
It should “give” about a 1/4 inch from the bar without much effort. Finally, while still holding up on the tip of the bar, tighten the bar nuts. Proper chainsaw chain tension is safer, it cuts better and it will extend the life of both your chainsaw and your chain.
What do you do if your chainsaw chain won’t tighten?
If you’re having trouble tightening the chainsaw chain, it may be adjusted properly already.
