age of my stihl chainsaw
 

i just bought MS 290 Farm Boss used chainsaw. I'd like to know how old it is. there are markings on it including

'311Y' and '00009674462C' and '250142708' .

Any idea what year this saw was made?

Unless something has changed, Stihl doesn't use date coding, but sequential serial numbers. There is a code for the country of origin, but i don't remember it. At least that's the way it used to be, it may have changed....

Have you tried contacting Stihl? Tell them you bought it used and want to know. I've never tried with Stihl, but everyone I have has always helped.
