It takes a max of 2 minutes to sharpen using the stihl tool. There are videos on youtube on how to use it, it will take longer to watch the video then it will to sharpen. 

I touch mine up frequently and it is very noticeable when it is sharp. I have never had a chain stretch out of adjustment range but I don't do that much cutting.

^ Yea that.  If your chain has never been sharpened and you've cut for more than a handful of hours, it's dull enough for a touch-up.  Dull chains run hot and grab more causing them to stretch.  Inadequate oiling will only compound the issue, making even a sharp chain run hot, which means it won't be sharp for long.

Run your finger over the cutting edge of the chain, especially the leading point - does it dig into your fingertip?  Like 'cut you' dig into your fingertip? 

Put a piece of paper on the ground and point the end of the bar at it.  Spin the chain up a few inches away.  Is your chain throwing oil on the paper?

What do your chips look like when you're cutting?

Find any guy who runs a saw for a living and ask him if he's got a chain file or spare sharp chains in his box.  I'd bet you a paycheck he does.

On the subject of "sharp for life" chains, do you ever sharpen the blades on your lawn mower?  I know the ones on my mower are much beefier than the cutting edge of a chain, and the hardest thing they cut are buckhorns, yet I still have to sharpen them every few mows.

Again, I've spent a LOT of time swinging a chainsaw.  The only time the chain ever stretched was when the oiler wasn't working.

Agree x10. As I said earlier, I cut 5 full cords a year, for the last 25 years, and have never had a chain stretch. There's something wrong here if it's stretching that quickly.

Getting plenty of oil and since it's happened on at least 4 other chain saws the same way I've got to think that's a norm for our area (wood, size & type of saw, etc)

Mine is a 16" and they were using 2 14" and 2 18"
