084 kickback?

[beenthere]

I'd agree with John Mc take on what happened, although exactly what happened is unknown.

I enjoy reading the different opinions, but not the challenges that someone else is wrong.

Yeah, you would need to sit down and have a good look at the stump to work out exactly how it happened. Both mechanisms could have pushed the saw back out.

Either way there are methods of avoiding it.

1. is slowing down and pay attention  ,  my bad habit.  I got in a hurry the other day dropping dead ash for a guy for firewood. Guess what happens when you cut through the hinge when your not paying attention and the saw is flying through the cut  .

??
Were you cutting with the top of the bar and moving to/into the hinge?

I often make the plunge cut just behind the hinge and finish the hinge with the top of the bar. Don't want to saw into that hinge or the saw can kick back out.

  Well you can argue and discuss it 'til the cows come home but truth be known they've been cutting big trees with short bars for years . It's all in how you do it ,some can some can't .

Oh say too that deal of cutting the hinge is something just about everyone has done at one time or another ,guilty myself .Lifting one off the hinge with a wedge has happened a time or two to most I might also add . Feet don't fail me now .  Run rabbit run .

Years ago I had the same kickback situation with my Jonsered 920. Was felling a large spruce in the backcut with the top side of the bar,tree came back and pinched the chain, saw kicked out and back of rear handle hit me in the shin. *DanG near broke my leg. Even with safety pants on the skin on my shin never healed properly .The chain was new so the bar wouldn't pinch as well.
Then about 10 yrs later the exact same thing happened with my 066 Mag. This time the skin at that same point broke and today is scarred bad. Some of the worst pain I ever endurred.

My newbie self dont feel so bad about taking out my shin now  .  Thanks for letting me know that even you pro guys get smacked every now and then too  .   

[Al_Smith]

I suppose we all have stories .Mine is an 048 that can flying out when a log collapsed on it .I shoud have  driven a wedge and I knew better .Getting in a hurry is what gets you every time . Needless to say I uttered some foul words  over that one and limped for a day or two . The handle of a saw is a lot tougher than a shin bone I'll tell ya that .

The other day my co-worker put a skip tooth chain on our 044.  I went to do a plunge cut and wow, whats going on, then I checked the chain.  We never had a skip tooth on that saw before.  Needles to say no plunge cutting that day and from now on I'm checking the chain when I take it out.

Huh?    I've been running skip tooth chain on all my big saws for three years now and plunge cut all the time. A couple Husky 372s and a 395. I would put skip on the MS880 but the local dealers don't carry skip and I'm not buying a roll of .404 for a saw I use 3-4 times per year.

Kickbacks happen. Usually the fault of the operator. Had my 2100 come back on me one time. Didn't lose my fingers but probably should have. Had a skidder on my butt, didn't brush out around a big cedar, in a hurry, hit some brush on the off side and back came the saw. My fault.

I think it's all about Position (of the saw bar), weight of the stump, and power of that 084. I've run mine, off and on, in really large trees since 2003. I have had it kick back the handle portion into my body three times-lightning fast, too. Never had the bar and chain come back on me though. Mine is an 084 with the chain brake and hand guard. This has been run with bars from 24" to 72"; .063/404 chains.

I agree that a full skip chain is more prone to kick back than standard sequence.

its lack of cutter teeth make it grabby in short cuts, and its kickback potential is high.
