A dull chainsaw can be a very frustrating and tiring obstacle while using your chainsaw because it will require extra effort and consumes more time than necessary. There are a couple of reasons why your chainsaw will dull quickly. They are, you might be using the wrong file size for your chain, so you are advised to check the user manual, you might be using too much energy while filing, and this will make the chain dull quickly and also create cutting edges that are too thin.
