Question
I 'm going to sharpen a chain but I Don't know what size file to use. It is an older McCulluoh Electric. It is a "Model Electramac EM 14ES .

I don't know where to look now that McCullouh is gone.      Thank you.  

Answer
Hi Cameron,

First, you need to determine what size chain you have.  The pitch is the distance between the chains' drive links.  Next, use the file chart to get your required file size.
