How to sharpen a chainsaw chain with a file
I have many people ask me the question about how to sharpen a chainsaw chain with a file? It really is very straightforward and the video on this page is a good example of how to sharpen the chainsaw chain with a file.
First of all, if at all possible try and support your chainsaw in an engineering vice or a portable stump voice if you’re out in the field. It makes sharpening your chainsaw so much easier if it is supported securely and you will do a better job sharpening your chainsaw! The tools required to show your chainsaw a round file and holder, a flat file and a depth gauge.
Ideally it helps if you can identify the parts on the chainsaw chain by name, this is all explained in the video, it also shows the importance of filing the rakers down as the chain teeth wear.
Firstly when you sharpen your chainsaw chain, find the tooth that is worn the most as you need to file all the teeth back to the same length. Keep an even pressure on the file and make sure that you use forward strokes as the file only cuts one way. If the chainsaw teeth are not filed back evenly, it will result in poor cutting performance. Make sure that you have the correct file size for your chain as chain sizes do vary. On your file guide you have lines marked on the guide which help to put the correct angle on the chainsaw chain tooth, make sure that you hold the file at the correct angle. Remember that when you are sharpening your chainsaw to file every other tooth and then turn your chainsaw around and sharpen the remaining teeth. When you have finished sharpening the chainsaw teeth, place the depth gauge onto the chain and file any rakers that are too high. If the rakers are too high, it will stop your chainsaw cutting efficiently.
It is always a good idea to carry a spare chain with you as you never know what you are going to come across when you are using a chainsaw. Always keep your chain sharp as a blunt chain puts more strain on the saw and the operator!
