good pix, working themes!! enjoyed seeing... did you say outside working... It was between -8F and 9F when I was cutting over two days.
Yes, but it was mostly clear with no wind. My hands got cold at times because it is almost impossible to keep gloves dry working wood in winter. However, everything else was good.
Cherry just does not split as well as those other woods, and Maple can be worse (especially Norway Maple).
Sounds like there is something wrong with the oiler in the 261, or it is plugged. Make sure nothing is obstructing things. That said, for the size Oak you got there, a 60 or 70 cc saw would be nice.
We have a mostly oak-hickory-black cherry forest, but it is incredibly rare that we ever lose a cherry tree and when we do they are often 6" or less in diameter and do not need to be split. I have thought about getting an MS441, but this is the first time in years that we have had anything over 24" so it is hard to justify the cost. Maybe I'll try and find a used one.
Does the 261 have an adjustable oiler? If it is like my 271 it has a fixed "epa" oiler that barely puts out enough oil for a 16" bar and sharp chain. A 20" bar and sharp chain and the bar gets so hot its not funny.
The 20" bar and chain were brand new--I bought the bar for these trees. It does have the oiler adjuster and it is maxed out. When I ran it with the 18" bar this summer and fall, oil was flying off the bar. I did have oiler problems last spring and brought it in for service and the dealer said the oiler went bad and they replaced it under warranty. After it wasn't cutting on this outing, I dropped it off again for service. The dealer called and said it was oiling great in his heated workshop... He said I needed to have winter-weight oil only in the tank. I am a fanatic about my tools and they are kept clean, sharp and oiled. Based on what the dealer told me, I think the combination of extreme cold, ice, thick oil and sawdust was just too much for the saw. When I get it back I will drain it out, refill with winter-weight and try again. That failing, I will just wait until spring.
