Just scored a new saw.

I just got a Stihl 021 from a friend of mine. He was never comfortable using a saw so he finally decided to get it out of the garage. I don’t think it has more than a few hours on it, still has the original chain. I put fresh gas in it and started it right up.
Is there a chart that ranks the older saws? I’d like to know where this falls in relation to my Stihl 170 and 290.
Plus what maintainane should I do on it, to put it back in top shape?

This is the instruction manual in case you don't have one.

Here's a useful chart.

The 021 is a smaller saw but considering the price, it is a super deal. Lots of people use this type of saw for limbing but it certainly can cut down mid sized trees.

So at 35.2cc/2bhp it looks like its a little bigger than the MS170 (30.1/1.7bhp), equivilant to a MS 180 in bhp (2.0bhp).
It has a wider tooth though.
