If the chain comes off easily from the bar, it doesn’t have the tension near about you need. Actually, it indicates a loose chain you need to tighten it asap.

Again, an overtightened chain of the chainsaw is also considered as bad tensioned. If you don’t leave a tiny place between the chain and the bar, it is impossible for the chain to play a little bit. And the chain can break during the operation.

Proper Tension

Hold your chainsaw’s chain and try to pull it up. If you can notice a tiny fraction of space between chain and the bar, then the chain is attached correctly.

But remember, the space between those shouldn’t be too much. The area should stay at a reasonable size so that the chain can play on the bar smoothly and doesn’t come off. Sometimes you can notice that your chainsaw chain tightens itself. And it is not the typical scenario. In this case, you have to troubleshoot your chainsaw also.
