Stihl yellow chain

On my saw came a stihl chain that has a "c" and a "3" on the tooth. I should have asked the fella for some more info on it but didn't. I do know its a "yellow" chain not green. I've googled chains to learn the difference and read other threads on these types of things but figured you all could put it in country boy terms that I could understand. So what the heck's the difference? I'll try to post a picture if I can get it to work.

 

Green and yellow are markings for kickback potential. Green is low and yellow is higher.

I believe the 3 refers to a .050 chain..

 

Yes I believe the 3 is .050 gauge and I think the c is for comfort . Usually the tie strap is yellow or green.

 

Thanks fellas. Makes sense. Finally got a pic to load.

 

3/8 RS @ .050

The green label chains have the extra hump just before the raker

 

3 on the drive link indicates .050 gauge. 3 on the cutter indicates 3/8" pitch.

 

Yellow is normally RSC from my experience. More of a true chisel chain, think old school. I run it on the bigger saws and like it.

 

I see a 2 on the cutter in that pic, which makes it .325 pitch.

 

I use a lot of Stihl RS chain mostly regular 3/8's" .050 but use .325" X .063 too.

RS is my favorite.

 

I thought it was a 3 ............. if it is a 2, then you are right that its .325
If it is a 3, then it is .375
the OP states that it is a 3

 

Yep, I was wrong. I zoomed in further and it is indeed a 3. So, 3/8.

 

Isn't the C on the tooth link mean full chisel? (as if a guy couldn't see that just by looking at it)

 

Stihl RM semi chisel chain also has the yellow tie strap on it

 

Not to keep asking questions, but what does RSC and RM stand for? Just tryin to learn here.....thanks guys
