When I was working with one every day, I carried it over one shoulder using the pad from my backpack shoulder strap to cushion the bone underneath. We walked from one tree to the next with one hand on the saw handle in front and the other hand holding an axe or shovel. I remember one time trying to cross a stream with that thing on my shoulder and the handle behind me dipped down into the water when I got out in the middle. The force of the water yanked the handle in front of me out of my hand and pulled the whole saw around my neck until it finally fell. Luckily the teeth got snagged in my shoulder strap, or else it would have cut my head off instead.
I remember another time I cut my partner's leg pretty badly with the saw one day while cutting a log. The trailhead was miles away up several long steep hills, and there was no question of getting him to a hospital for stitches. One of the guys on the crew used his tent repair kit and some dental floss to do stitches that night around the campfire. Then we split up his pack so he wouldn't have to carry anything the next day as we walked out. By the time we got to the trailhead, he had lost a lot of blood and was white as a ghost. I thought we might have to carry him, but he made it.
Then there was the time we got both our crosscuts pinched in a 5 ft + diameter log and had to spend 2 days chopping them out with axes.
If I never see another one of those damn things again, it'll be too soon.
