HOW-TO Fix A Burred Chainsaw Chain That Came Off The Bar

[@JF-fx2qv]

The key word: "People." .... " The main reason this is happening is because PEOPLE ...." BINGO! Reading in between the lines: Everyone is a rockstar. Meaning few; these days, are LIVING WHAT THEY DO. In other words; why hire a professional when you can DIY. Note: this is not a rip on DIY ... I'm all about DIY, but I live it, and I'm not trying to save a few bucks. Often times; the cost of establishing yourself (tools and tools for tools etc.) can add up to more than the job or task you wish to accomplish. Moreover; at a greater risk. Moron .. I mean moral of my story ... get ed-u-ma-cated ... if you're really a DIY'er and into all fix-it things and not a poor man trying to "get er done" and really don't care about tools, fixing, building then keep reading, watching and do'in!

Good demo! I keep a sharpening stone in my gear. I lay the chain out flat on my tailgate, and the stone will hit about 8 links all at once. Good quick field repair.

[@tomronan601]

Donnie is the real deal.

[@SeanRhoadesChristopher]

From experience, cutting into multiple small branches and vines can also cause a well tension chain to pop off. One branch at a time, even if they are small, according to the instruction manual.

[@jessecoonce1363]

I was thinking the same thing, this is about the only way I ever end up throwing a chain. Whippy little branches are good at grabbing chains and pulling them off.

[@strawberyyicecreamdream216]

this is why I am here.

[@aaronwright561]

This is what happened to me i was always good about keeping it tight but it flew off cutting a small branch. Annoying

[@claywaves]

Same thing happened to me. This fixed my issue! One small branch at a time it is!

[@tracyr5594]

why im here :) cutting small twigs clearing the area around me made chain jump and come off. Nice to see it should be easy to fix. Brand new chain too.

[@GaryT1952]

That die grinder is one of the most valuable tools in any shop...pro or DIY...great content as usual donyboy73

[@LukaArtelj]

you know hat only pussy uses gloves for handling chain, looooserrrr !!!!!!!!!!!!!!! I haven't cut my self with a chain never in my life and I have been using it every day for the past 20 years

[@whiskybar]

Wow, I just hired a chainsaw and of course the chain fell off right away because I forgot to pay attention to the tension. I could not get it back on like I'm used to with my ordinary saws because, the chain would not slide in the bar. This was it! Thanks a million

[@peterz2160]

Thank you for sharing this video Like you said it happened on a brand new chain after a few cuts of small hedge branches. I had forgotten that chainsaws don't like small thin branches.

Even though I don't own any small engine tools I still like watching these videos. Not sure how I came across this channel, but glad I did.

[@bobmcl2406]

Good simple tip to save an otherwise-still-useful chain. Thanks Dony.

[@eaton3253]

Thank you for this instructional video. I was having this problem all the time and kept going through chains. I spend about 10 minutes taking off the burrs and now it works great. This is going to save me a lot of money on chains in the future.

[@bolokraymond3190]

Thanks Donyboy73 for the video, it helps giving me ideas.

[@rodneybrand8521]

It's also a good idea to check chain tension on a brand new saw..sometimes it can be too tight or too loose..

[@bolokraymond3190]

Yeah, I bought a new STIHL MS720 chainsaw and this is happening to the chainsaw right know. Maybe you have some ideas on this, may you please help?

[@rpavlik1]

Very useful! Haven't had this happen, surprisingly given my past "crimes against proper chain tension". Die grinder seemed pretty fast, before then I was thinking "this could really go for some kind of fixture to hold better than a hand and top of a vise". Just tried a pneumatic die grinder for the first time recently, was lovely, now I need one of those flap discs for it. Thanks!

[@rogerjamestv]

Thanks so much for showing how this is done. As you said, it happened on a very new chainsaw and I would have hated to buy a new chain. This is my first chainsaw and I wouldn't have had a clue how to fix the problem. I ended up using a Dremel with a small grinding disc on it, clamping the chain flat onto the workbench and coming at it from above, then sliding the grinding disc underneath and doing the underside with the top of the disc, so I didn't even have to flip the chain over. This worked great, 15 minutes later I was back to cutting.

[@martinandmariefecher3524]

Thanks a lot, Dr. Saved a $23 chain for me.

[@hei_________katdalunga4854]

This is what I am looking for Thanks for the video . God bless you

[@troycummings5083]

You’re good at instructions Dony

[@jamese9283]

Dony, MUCH MUCH easier to put the chain back on sagging loose, run for a few seconds, tighten half-way. Repeat. Let the burrs grind themselves off on the bar as they travel around. There is plenty of metal on the bar to remove the tiny burrs. Been a pro doing this for 30 years and it always works.

[@bolokraymond3190]

Thanks for this comment.

[@nobodythatyouknow241]

Exactly the same thing I have been doing for 40 years.

[@johng2779]

[@rverro8478]

Nice to know. I bought a new chainsaw and, didn't know about that problem. Merçi Dony.

[@COSpacegunner]

I kicked the chain on my MS 170 by using a Super, full-chisel chain while cutting up small branches, but failing to keep the RPM's up that the cutters grabbed and threw the chain off the bar. I learned the hard way and spent a lot of time deburring the drive links. I made sure the bar was undamaged as well. The chain tension was properly adjusted when it got thrown off the bar. I use my 015 with a Micro, safety chain to cut small branches now, and keep the throttle at full tilt.

[@roberthamilton9123]

Good morning ☀️ Don thanks for sharing your information and knowledge with us it’s very appreciated and helpful have a great weekend buddy 😀😀

[@d.j.5790]

Nice! Many, many thanks good sir.

[@markyoungoutdoors2497]

So glad you mentioned pulling up the bar before tightening those nuts! It’s crucial! Otherwise the bar will rise and overtighten the chain and likely snap the chain when you go to cut. Excellent video! Thankyou for sharing this important information.

[@schlomoshekelstein908]

if the bar rises the chain gets LOOSER. if you pull the bar up and the bar DROPS somehow, it will TIGHTEN the chain

[@markyoungoutdoors2497]

@@schlomoshekelstein908 I respectfully disagree. Decades ago I learned this first hand working at a golf course. I kept breaking the cutting chain because I didn’t hold the tip of the bar up as I tightened the bar nuts good and snug. You have to check your chain slack while your holding the tip up while the nuts are almost tight. Once the tension is right, you once again hold the tip up as you snug up those two nuts. I’ve never again had a chain break in the decades since learning this concept.😊

[@kleintjk]

Excellent. Expert advise. Very helpful. Thanks

[@stanleymorton2992]

Good job. My chain popped off today and once reattached, chain wouldn't move on bar. Chain is fairly new, so following your advice I will try and save it by filing burrs. It's worth a shot. Thx

[@David-dq7uz]

I filed the deformity on the chain and it worked

[@Cinder2008]

Thanks for the video. I didn’t know what would happen if the chain was too tight.

[@jimisnotunique]

Great video. Thanks. Very helpful in fixing my stuck chain.

[@plemli]

Ssems these new chains are very soft (which is good in a way) and the bars very tight. I can't count the number of times a chain popped off over the years, but I never had to file or replace the chain. Dremel works great to smooth the burrs.

[@MaximumZargon]

My old colleague used to just force the chain in and run the saw flat out until the sparks stopped. Obviously can't recommend that method, but it did work!

[@johnnyjimj]

That's how we used to do in the field 😂

[@jamese9283]

That method is much easier, though loosen the chain first, then re-tighten.

[@donyboy73]

if it fits in the groove, it's unsafe but each to their own devices lol

[@jamese9283]

@@donyboy73 I wish I could show this to you in person. It is completely safe and easy. Most burred chains will fit in the nose and back of the bar after you loosen the tension, and a few revolutions with the engine will remove the burrs and the chain drops right in.

I watched to see if there is a better way than what I had done previously which is use a flat file. Turns out there is, but I don't have a die grinder. I wonder if there is a suitable Dremel attachment that might work?

[@ronpatterson6420]

I did something really stupid 2 years ago, I ran a 50 gauge in a 58 gauge bar. I had to hand file every drive link it was a 32 inch bar. Hard lesson learned! Check bar gauge first!lol.

Need to also check bar itself too and flip bar over and check nice informative video Dony 👍 666 OUT

[@minchae2286]

First, thank you for posting this video. I believe the tension came loose during cutting a thick branch and it got kinked and I used it right away without checking the tension. The chain came off and when I put it back together, engine started fine but after releasing the safety the chain did not turn and caused bit of smoke. After watching your video, I believe it is due to burred chain causing it not to turn. I stopped after couple attempts to run it realizing there is a problem with how the chain was difficult to slide it in the bar groove. Will repairing the burred chain make it run again? I only had this chainsaw for little over a year using it to cut small trees and thick branches around the house several times. Thanks in advance!

[@donyboy73]

yes if you do what i did in video the chain can be re-used again

I have a small Stihl saw. MS 170. After 1/2 hour to 3/4 it dies and has no spark. I have changed the ignition coil, spark plug and even the fly wheel.

[@bolokraymond3190]

I bought a new STIHL MS720 chainsaw with 32" bar and chain. I mounted the bar and chain on a chainsaw body, tensioning the chain loosen and ( the drive links not sit in the bar groove completely) moving it by hand it moves freely. But tighten it to a standard chainsaw tensioning, (when the chain drive links fits in the bar groove), the chain didn't move freely, though the chain drive links fits the bar and run smoothly. May you please help me solve this out?

[@adammosher5818]

I have a 20in and want to use a different size bar and chain do I have to change the clutch and drive sprocket

[@jamese9283]

The pitch & gauge of the chain must match the pitch of the drive sprocket and the pitch & gauge of the bar. If these elements don’t match then damage will occur. If you buy a longer/shorter bar & chain, make sure they are the same pitch & gauge as your current chain, and you won't need to change the sprocket.

[@donyboy73]

you will either have .325 or 3/8" pitch sprocket so go with what you have
