Full chisel sharpening.

Vaguely related to this thread, I've just got a new chain for my MS 261, as I damaged a drive link or two when it came off a day or two ago. I run a 14" bar on it, basically it's the one for the MSA 300 and while looking, I found out that it's a full chisel. ( Apparently ). Seems odd to me, I hope I can just sharpen it normally as I would a semi chisel, normal round files. 

Any thoughts or advice on this gratefully received as always. 

Standard 3/16 - 4.8mm files for those

I get round behind the power head to file so I can't see the front of the teeth though, dot of pen helps. Got some old OHP pens that are never going to be used in an office again.

 

Also my eyes aren't all that great so can't see the metal filings unless I bend down close, don't like bending down every tooth.

Helps more as the eyes diminish, also it's quite nice when you draw the next cutter toward you to file it and see your marked cutter come up over the tip, you know you are nearly there.

I never pull the chain back, only forward.

Can I ask the reason?

I've never really thought about it, I just put the file in the gullet of the next cutter and pull it back to a comfy position. Hope I'm not committing a heinous act while sharpening!

Well as things get worn the chain can snag more easily when you pull it back, if you do it with an ungloved hand it can injure. If you use the file and it jams the file can take the tip off a full chisel file. I move the teeth forward with the file on the back of the cutter for the left hand set  and my hand with the right hand set as I advance those two or three cutters and sharpen them in one position.

 

Mind I only sharpen a chain occasionally now whereas it would be a light touch up several times a day at work.

You don't want it to start up in reverse next time you use it either.

You rotate the chain backwards?

Sorry, should have read the thread to the end before posting 🤦

I'm beginning to think I'm guilty of a terribly offensive act!
