Evening lads,
I have a technical evaluation coming up and a part of it is identifying chains from the codes stamped on them, as well as the file size needed for sharpening.
It’s usually limited to Stihl and Oregon, and the most common chains of each, more of a general knowledge rather than specific thing.
Anyways, while revising I figured I’d make something that I can use, but maybe others could use too, my hope it to be able to get 100% consistently.
All this to say:
docs.google.com
Make of it what you will, any feedback is appreciated.
Take care

Stihl & Oregon Chain Codes + File Sizes
If you're completely new to this, you might want to look at chain/file charts beforehand, as this will all be alien otherwise.
