How Do I Know If My Chainsaw is Tightened Right?

A properly tensioned chainsaw is essential for the effective working condition of your chainsaw.  Of course, your chainsaw should not be too tight or to loose. So how do you know when your chainsaw is the right tension? There is no laid down formula on the exact tightness needed for chainsaw tightening. Mostly, it depends on how tight the user wants it to be and the job at hand.

These two tests, the snap test and the pull test will guide you on the extent you should go when tightening.

Snap Test

Stretch the chain from the bar as much as it can go then release. If it snaps back intact know that you are on track. NB:  if the chain is tensioned too tight, it will not easily stretch from the guide bar and if too loose it will not fit properly into the guide bar after releasing it.

Pull Test:

Simply stretch the chain away from the bar to the extent it can take, then release. The chain will be completely off the bar but the drive link will not be. You will find it hard to stretch the chain if it is too tight, but if the drive Link completely exits the bar, know that the chain is too loose.

How Often Should You Tighten Your Chainsaw?

You may have to tighten new chainsaws frequently because of “Break-in”. Break-ins results from Frictional force between the chain links. A new chain will need to stretch a bit to function properly. For older and well-used saws, you may not have to tighten often if your saw is in good working condition.

You will only experience loosening all the time if your chainsaw has some issues as have been discussed earlier.
