have one of these grinders wondering what they talk about 10 degree adjustment  Thanks Scott

Scott,

Most chain is filed with the file held level, or at '0 degrees'. Some people file full-chisel chain only with the file held at a 10 degree angle, rising from the center of the chain up to the point/corner.

To get this same angle when using a grinder, the vise needs to be tilted. Not all grinders have this feature. The Oregon 511A, and 511AX have this feature. The 510 does not.

I have the 115A....
Where do I find this adjustment ?

[HolmenTree]

Offset grinding is the industry term for the 10° adjustment.
Stihl for example no longer advises 10° filing angle.
Once recommended for lessening side plate angle and reducing top plate bluntness for cutting dry or frozen wood.

The 10° 'down angle', as it is also called is optional.  Above, I stated that it is only used on full chisel chain.  In recent years, Oregon has been recommending it for more chains: https://www.oregonproducts.com/pdfs/FilingAngles.pdf

I typically don't use it, because it is an extra step or two to tilt the vise back and forth, and I don't feel the need with my cutting. I will do it if someone wants it, but it is not a good idea to go 'back and forth' since it wastes a lot of cutter life to keep changing.

Kbeitz, the info for your 511A is in the manual (https://www.baileysonline.com/PDF/Oregon511amanual_english.pdf) on page 11 (13th page of PDF file). Loosen the same knob that you use to rotate the chain vise, then tilt / rock the vise forward or back for the 10° angle.  There are small ball bearings and springs in there that will 'detent' at the fixed angle, and some markings cast into the Right side of the vise. Tilt the top of the vise away from you for the Left hand cutters, and tilt the top of the vise towards you for the Right hand cutters.  Tighten the knob and double check the vise rotation / top plate angle (e.g. 30°, or whatever you chose).
