should this build up be of concern?

[Flavo]

I don't recall seeing this kind of black in here before. Should I be worried about this or am I doing something wrong? The only maintenance I have done on this 445 is to clean the air filter that already looked pretty clean to begin with.
Thanks, Mike.

Not quite sure but looks like the chain guide thing with numbers stamped on it is getting rubbed by chain. Don't know/think it is normal....Is you chain too loose or bent?

That's normal crap buildup.

Looks like a mix of chain lube and dust off the chain.

Thanks guys. I will take a better look at it today and see if that is indeed a rub spot.

When your done runnin the saw for the day,,,use a air compressor and blow out that junk that settles under the cover. Only takes a few minutes to do,,keeps the saw nice and clean. You can also blow out your air filter with the compressor to keep it nice and clean.

It looks just like my 455 cover yesterday when I sharpened 4 chains,nothing in there that would concern me , I would clean it up and get back to cutting and did .
