Thanks for the tips. tfp!
I'm not really small in length, but more so in overall mass.
. I was wondering if the saw would be too "strong", not having any prior experience with pro-saws. Now that I've used it for a couple of tanks sawing-time, I see that there was no need to worry. It is a strong saw, but handles very nicely. I am glad I did not choose a heavier (weight) saw. The MS261 C-M is a joy to work with. Just as you say: no need at all to put weight on it. It cuts like a hot knife through butter! I'm working on a couple of poplars, now, which is of course very light wood, but, earlier, it handled the heavier old oak very well, too. It does like its fuel, I must say (or maybe the fuel tank is just not that large..).
About the oiler.. the dealer told me to keep it in halfway position...
