Got a MacCat 2.3ci. I'm sure that having a pro sharpen chain is best.
But between visits to him, do you recommend my doing it? If so,
what is best way to do it?

 

Sure, you can absolutely do the job yourself! Ideally, you'll want a vice to sturdy the saw in. Then you'll need a file/guide combo sharpener. This helps you do the job correctly. You may also want to purchase a depth gauge and file in order to file the depth gauges properly as well. Check with your local saw shop for these tools. Or check out Oregon products website.

 

There is a whack of web sites that teach how to do that.

 

I recommend a sears electric sharpner, it looks like a dremel tool. I'd touch up blade every two tanks, takes minutes, and you will never make sawdust.

Don't need a pro with this tool, the tool is the pro.
