Funny you should mention "044 in a tree".
Last summer I was working with another sub on a big ugly boxelder. It was a Saturday, and the customer's neighbor was having a party.
We had to lighten the backside of it to drop it in the street. He being the more experienced climber, volunteered to drop a 24" lead about 20 feet up. We had a beat-up Jons 630 along, but it was dull.
So I tie off my new 044 (less than 10 hours on it) and up it goes, gleaming in the late afternoon sun as it bounces heavily off the trunk along the way.
I've barely got his rope straightened and he starts into the limb. No undercut. Before I could say or even think anything it was arcing down, with my 044 stuck in the fibers.
Slowly, almost deliberately, the tree pulls the saw away from his hands. It drops off to the side a little, crashing on some other logs already on the ground. This sends the filter assemby flying in pieces. The saw then bounces what had to be ten feet in the air, and then hits solidly on the neighbors's asphalt on the tip of the bar. A few more little bounces left it upright, still running in the middle of the driveway. The party of 30 people next door, watching the entire episode, fell silent. The only sound on the whole block was my wounded 44 at idle.
Thankfully. Thankfully. Thankfully no one was hurt.
The climber and I are still friends.
The saw was fine, $120.00 later. (Bar, filter, filter cover, filter mount.)
Lessons learned:
1) Never cut for an audience.
2) Never start a complicated tree near the end of a hard day.
3) If I break my own stuff I feel bad. If someone breaks someone
else's stuff we all feel bad. If someone else breaks thier own
stuff I feel just fine.
4) Communicate. Discuss strategies beforehand. Make sure
everyone knows the plan.
5) Heavy saw + climber = bad idea.
