He mentioned pivoting the saw between 2 branches - The number one way to get unexpected kickback because you're concentrating on the limb you're cutting and not on where the tip is - cutting up under another branch. This video covered everything. Be aware of what you're doing and where your bar is at all times. Oh, and one more thing - NEVER walk with a running saw without first engaging the chain brake.
I wish I had a teacher like this when I was at school, he just seems to make you listen! Showing the battery drill as a kickback analogy enabled me to understand everything he subsequently said. I'm 63, and getting my first chainsaw tomorrow!
I've been using a tiny pos electric chain saw, but finally purchased a real chainsaw and decided I should do some research before using it. Glad I did! Found this video before I hurt myself. Thank you so much for sharing this.
Possibly redundant by now, but if you haven't, try one of the basic chainsaw operator courses if they're available in your country/region, it makes a world of difference. In the UK it's the CS30/31 combined course.
This video is great, informative, practical, and not fear mongering. I just bought my first chainsaw and other videos made me scared to even use it. Now I think I can give it a try. Thanks Workplace North.
What a fantastic narrator - riveting performance - John Wayne does Kickback. Hope the man is still kicking as that was filmed 25 years ago, but the content is still very pertinent.
I expected this to be some B.S. overblown safety video but it was actually very informative and well done. I knew about kickback, but never really considered what could be done to prevent it.
learned a lot. I never had a bad kick back event and didn't understand how it could happen. I actually thought it was a BS scare tactic.This was very well explained. thank you for the video.
I worked in a hospital emerg room - I saw one kick back incident- guy was missing most of his lower jaw some of his upper mouth (missing most of his teeth too) and you could literally lift his cheek and see nothing but bone underneath like it was a flap. He got life flighted to the nearest major trauma center from our hospital. Nasty shit.
@@John_Gillmandude is a dumb a. He was using a chainsaw on a ladder, strike 1. Tried cutting with the tip of the bar above his head, strike 2. The only thing that saved him is the chain brake.
This is an excellent video and the most informative I have seen on kickback. Been running saws all my life and (thankfully) never experienced a critical kickback, in fact, to the point that I wondered if it is really real. Now I see how easy it can happen, and how that ease grows with fatigue and complacency. Thank you "Workplace Safety North" for posting a First Class safety video!
Cutting with full rev is so important, i see so many people for no reason tapping the throttle button for no reason when cutting, i know you can use it when making a cut, but if you are bucking some wood, just keep it under full rev from start to the end of the cut. You can hit something with the tip of the bar with full rev, and it digs in, but as soon as you release it, it kicks back. Also the keep left arm straight truly saved me so many times when it happens. Also, smaller saws/bars are more prone to kickback, and is much more violently in my experiense.
8:56 - "That's also why you have to start EVERY CUT under FULL POWER and keep it up until you are finished". This is the first time I've heard any chainsaw instruction or safety video explicitly say this! I've been wondering about this for years! See, I thought by not putting the saw at full speed you will be safer if anything happens (kickback, what-have-you) -- driving a car faster usually results in more damaging accidents that ones at a slower speed. But, every time I've tried to "vary" the chainsaw speed while cutting it has kicked back!
Glad that I found this excellent video before heading out to cut wood...so much info presented so well in just 10 min. Thanks for sharing a lifelong learning in this little video.
Well, if your company is smart, and you are in the US, your company is liable by law under OSHA to train and inform you on potential dangers and safety measures. Though I personally believe EVERYONE should watch these videos, just for general safety for everyone to know how to use tools, never know when it'll come in handy.
My grandpa worked as a faller, and bucker for almost 30 years. He had a couple kickback accidents, luckily they weren’t severe, and he witnessed a few accidents from his coworkers. The woods is a dangerous place to work in. Even working around the house with a chainsaw is dangerous. I remember the first time I used one, my grandpa specifically told me this. “You better make sure that saw does not touch anything at the tip, because if that saw kicks back, you’re done. Those sons of bitches have no mercy!” So I would like to say thank you to my grandpa, and the people who made this video! Hopefully others will watch this and take it seriously!
great video..only differences from what i was taught in the uk in always have the saw up against ur knee ur whole body weight resists the kick back as much as possible, and if it does happen the saw passes by ur side not over ur head, and also remember to use the pushing or pulling side of the bar in the right circumstances and avoid the potential of a kick back as much as possible by making sure the saw runs away from you if anything
thanks a lot. very informative. say if I were cutting a large diameter tree stump, horizontally, what can I do to avoid kickback and getting the tip stuck on this one ? maybe use a larger saw ?? cheers
thank you best safety video regarding chainsaw kickback and how to bother understand and prevent it plus how to protect yourself too. i recommend everyone who just bought a chainsaw to watch this video first. and i will be making sure anyone who uses my chainsaw has either watched this video or are already experts in using a chainsaw properly and safely.
Great video! There is a video on RUclips of an injury to a man't forearm from a chainsaw. Do you not need to wear any arm protection? I had no idea about the technical aspects of sharpening and using a depth gauge. I'm way way safer now than before - thank you. Subscribed.
Complacently just kicked my you know what. I had been cutting all week. End of the week, 2 hour job finish, and while I hastily wanted to get home I left my chaps in the truck. 20' from me, second limb saw bucked hit my left knee, 27 staples, cut half way through my upper thigh tendon. 4 weeks of crunches. Always wear PPE{personal protective equipment}.
Good, clear....and fluent explanation. It's great to hear someone articulate who doesn't stumble with 'um' and 'er' or pad the time out with needless repetition or rambling. And not a single use of 'like'....which nowadays is obligatory several times in every Millenial's every sentence. Bravo!
I usually try to use the rear of the saw as much for cutting to prevent kick back. Was told by old timer. Never use tip for cutting been cutting since I was about 7 to 8 yrs old I'm 35 now.
What about the safety bar tip. This prevents the kickback area from touching anything. I just installed one on my echo cs-400. I don't see the pros using this. Maybe it's for weekend chainsaw users like me.
Brilliant advice! My son died instantly, in Feb2016, 20ft up a tree when the top-handled saw he was using kicked back. With handles so close together on the saw he could not have used the 'locked elbow' technique. I reckon it hit him in 1/3 of the time it took the chain brake to work. The cut went through his neck to his spine. Top-handled saws are so lively they should ALWAYS be fitted with bar-tip guards to eliminate kickback for climbers.
Easy. Avoid starting cut with "danger quadrant", the upper part of the tip. Start the cut with the lower half of the tip, and gradually transition to using the full tip. Of course, at all times keep all body parts "out of the plane of the chain" and not behind saw. You can't get hit there. Bet you knew that, and were just trolling.
My situation at present is that I have just purchased a baby chainsaw (I know - still dangerous) and before I even use it, I will get myself some chainsaw boots, chaps etc. as I already have goggles and ear protection with no need for a hard hat because I am not felling trees or de-limbing or that sorta thing. What I am attempting to do is to reduce the height of my hedges for which I normally use a hedge trimmer but I don't want to damage it by trying to cut through some branches that have become as thick as 3" !!! So ... where do I stand with the following scenario - cutting mostly across as opposed to up or down AND having to stand on a ladder or platform. I won't lie and say that I am not at least a little nervous so any advice or other youtube links along these lines would be gratefully appreciated...
I have a feeling that the modern Chainsaws of today have what's known as an Inertia Chainbrake. What that means is that if the tip of the guide bar strikes a solid object, the Chainbrake automatically activates, without the operater having to react. I'm not sure if the process only works if the chainsaw is being used vertically, or if it works when being used both horizontally and vertically
The chainbreak is activated when the saw slams back into the operator's hand on the handle bar. If somebody is not using two hands the chainbreak will not function. And regardless, a high powered saw can still fly out of the operators hand and is still dangerous after the chain stops, as it only stops after the saw is already coming backward with momentum. The example in the video that saw has a chain break but flew out of the users hand.
Julia Gale If you work with chainsaw you’ll experience them once in awhile and yeah it’s frightening I’ve had it happen a few times but the brake saved my ass many times...no warning the saw just comes flying fast back at you even if you are holding it tight
Respect deserving guy. 100%, AMEN, shout it from the mountain tops. Your PPE IS the last line of defense. Your attitude is your first. Your brain is your second. Everything else is situational and somewhere in between attitude and PPE.
I disagree with the full power statement at 8:22 If you hit something bad enough(bad enough tip angle with enough force, hit a wedge or hit steel, etc.), no saw is going to keep pulling the chain through, no matter how powerful! Even if it does pull through, it's still going to cause a kickback, because of newtons third law. The chain speed can remain constant, you will still have kickback if you are cutting hard with the nose because the force the chain is pushing down on the wood with must be equal to the force it's pushing the nose up with. So, if you know there is such a risk, you should saw gently with low chain-speed with posture that gives you a way to resist, that way you can handle the kickback if it comes. It's precisely when you got a powerful saw running at full chain-speed when kickback can be the worst. I saw a guy hit his plastic wedge with the nose during the back cut, it was so violent, I'm sure it would have rotated the bar around and hit him in the back of the calf if it didn't hit another tree on the way. I saw a guy cut firewood outside of his garage, he did a back and forth motion with his saw, then he came to the 4th cut and there was the butt of another log lying dangerously close to where he was cutting. OFC he pushed the saw tip right in to the end-grain of the other log and the saw hit him so hard in the skull that he was bleeding heavily even though the chain break did it's job. If it didn't stop the chain, his skull would be sawn right in two. This would have happened regardless of how powerful the saw was or how sharp the chain was. There's only 2 things that can prevent this, better technique and/or keeping the chain-speed low enough where the kickback is manageable even if the chain gets caught.
@@NoName-ml5yk Things like that happens. They make them out of plastic for the very reason that people tend to hit them sometimes. Can you honestly say you've never hit your wedge while making a back cut? All the cut marks on most people's wedges tells me another story. Even if it's not wedges, you can have old steel buried deep in the wood that can cause a real bad kickback if you're unlucky and hit it at the wrong angle. Ofc you can't calculate for this because it's a freak accident... Unless you're working on some trees that used to be part of a treehouse or something, then you can expect a ton of steel in the stump. Even if it's just wood, it will stall out any saw if hard enough and the feed is enough. Try hitting endgrain with the tip of you're nose, it will kick real bad, no mater how sharp your chain is or how high your chain-speed is.
He mentioned pivoting the saw between 2 branches - The number one way to get unexpected kickback because you're concentrating on the limb you're cutting and not on where the tip is - cutting up under another branch.
This video covered everything. Be aware of what you're doing and where your bar is at all times.
Oh, and one more thing - NEVER walk with a running saw without first engaging the chain brake.
This fella is the type of guy you want to listen to. Very credible wisdom.
👍
One of the best chainsaw safety videos I have seen
this has to be one of the best health and safety videos i've seen. he is such a good speaker
Outstanding tutorial. To the point, packed with information from an experienced "competent" person and concise. Thanks.
I wish I had a teacher like this when I was at school, he just seems to make you listen!
Showing the battery drill as a kickback analogy enabled me to understand everything he subsequently said. I'm 63, and getting my first chainsaw tomorrow!
7:36: There's a lot of things you can do prevent kickback and all you have to do is ALL OF THEM. . . ALL THE TIME!!!
and sharp chain
I've been using a tiny pos electric chain saw, but finally purchased a real chainsaw and decided I should do some research before using it. Glad I did! Found this video before I hurt myself. Thank you so much for sharing this.

I didn't realize that Ted Kennedy knew so much about chainsaws.
lol
gwmgbwi
Looks like a pup wood logger 🤨
Shame he didn't know that much about cars...
... or being a lifeguard.
How about drinking alcohol whilst cutting, never mentioned so I take that as an ok, thanks for that mate.
I assume he just made a joke ;)
you can't tell that the comment about it being ok to drink alcohol while using a chainsaw was a joke??????
Lol don't even tocuh it if u drank alcohol :P
No it's not using a chainsaw while drunk you are asking for a death wish
Because if it kicks back while you are drunk
Good advice.
very good, thanx
Great video. This guy knows how to teach
Tks soo much for this vid.. any advise on where Yo buy all protection gear?
Tools & More DIY go to your local saw shop, or buy online. I’m sure if a saw shop doesn’t carry one thing, they can definitely get it for you!
Hi great video and good tips on kickback
I have a feeling that the modern Chainsaws of today have what's known as an Inertia Chainbrake. What that means is that if the tip of the guide bar strikes a solid object, the Chainbrake automatically activates, without the operater having to react.
I'm not sure if the process only works if the chainsaw is being used vertically, or if it works when being used both horizontally and vertically
The chainbreak is activated when the saw slams back into the operator's hand on the handle bar. If somebody is not using two hands the chainbreak will not function. And regardless, a high powered saw can still fly out of the operators hand and is still dangerous after the chain stops, as it only stops after the saw is already coming backward with momentum. The example in the video that saw has a chain break but flew out of the users hand.

Remember that correct standing position is very important.
I disagree with the full power statement at 8:22
If you hit something bad enough(bad enough tip angle with enough force, hit a wedge or hit steel, etc.), no saw is going to keep pulling the chain through, no matter how powerful! Even if it does pull through, it's still going to cause a kickback, because of newtons third law.
