So, how do you know when to tighten your chainsaw chain? The answer lies in the tension.
If the tension is too loose it is unsafe to use a chainsaw and it needs to be tightened in ogre to be operated safely.
But, what does good or bad tension look like? Let’s delve a little deeper into what good and band tension looks like for a chainsaw:
If a chainsaw has the right tension it will still be only a little bit loose along the guide bar.
However, the chain links absolutely have to be tight enough so that you are unable to pull the drive links out of the bar nose.
So, when you are testing whether you need to adjust the tension you should pull the chain away from the guide bar and if the drive links remain engaged you will know that you have the right tension.
It is important to note that your chainsaw chain can be too tight and this can be unsafe as well.
So, make sure that it is a little loose but still engaged for the best results.
If the tension is bad you will notice that it becomes slack and it will pull away from the guide bar.
The drive links will become disengaged from the guide bar when they are pulled and when this happens you will know that you need to tighten the chainsaw chain.
Take note, that you can over tighten a chain. So, as we have said before, make sure that there is a little ply in the chain.
The drive links should not leave the bar.

By loosening the guide bar panel nuts you are allowing the chain the space it needs to be adjusted properly.
When you are doing this step make sure that you check whether you have a brake on the panel.
Some chainsaws will have a brake on the side panel and if this is the case for your chainsaw all you have to do it remove that brake before you take the side panel off.
The next step is to find the tensioning screw and make the required adjustment. This screw is usually found just next to the chainsaw guide bars.
Make sure to adjust the chain so that it is tight enough to not become disengaged but loose enough to have a bit of ply.
When you are turning the screw you will notice that when the screw is tightened you will also be tightening the chain and when you are loosening it the chain will also loosen.
When you have adjusted the tensioning screw to a satisfactory point and your chain is at a good tension you should put the panel back on and tighten the nuts again.
While you are doing this step it is essential that you lift the nose of the chainsaw while you are tightening the nuts.
Once you have done this you will have adjusted the tension of your chainsaw and the chain should be nice and tight. It really is just that simple!
