Thanks for watching. This chainsaw kept throwing its chain and the reason is so obvious when you realize it. It never occurred to that this was a problem but now I know and so should you.
My neighbor threw out a nice chainsaw on the curb and said the chain kept falling off. It’s a 42cc Poulan Pro. The sprocket is a little chewed up but she runs beautifully. Glad it caught my eye when I was driving by!
nice timing!
Thanks for this video, it's sure gonna help me fix my parents chainsaw.
They are definitely in that group of people that got frustrated and gave up after replacing the chain which led to similar issues.
no problem and good luck to you
Yeah, I lent a saw to a friend and he managed to ruin the entire clutch sprocket and bend the crankshaft by running the chain backwards and god knows how he got it wrapped up around the crank. But long story short he said "there is a wee problem with your chainsaw" I said "No no, your chainsaw appears to be ruined but the one your bringing me back is like brand new" What do ya know, saw came back so brand new it was in the box!
Nice man.
😂😂😂 Glad you got a replacement!
First: Buy 3 chains and one new drive sprocket. Change between the 3 chains when you sharpen them from time to time untill all 3 chains are worn. Then buy 3 new chains and change the drive sprocket. Than the cirkle begins all over again.
Second: Turn the bar upsitedown with every chain swap and clean the oil ports at the end of the bar. And remove the bur on the chain bar edge everytime you change the chain.
Third: When you have a sprocket with a bearing in the tip of the bar, there will be litle holes . Squirt grease in these holes everytime you fill up the gas tank. You can buy a greaser espacaly designt vor that task.
fourth: When you fill up your cainsaw, allways fill up the oil first. That way you never forgett to fill up the chainoil.
fifth: Never let your chainsaw unused for more than a half jear. Because the organik chain oil will turn into rasion and will clock up the oilpump and hoses. To clean this, is a royal pain in the rear.
And that is how you maintain your chainsaw. I learnd this from my father who learnd logger and worked for years in that trade.
And if somone would swap my chain, my property, with some other, I would freak out. Becaus I purcase expensive quality cains that are worn in and match with my sprocket. How could somone even get the idear to swap chains, that are your property with the property of somone else. It's like bringing your Car into the stealership and they swap just the tires with other tires from another customer who had cheap chinese tires. Just unbelevable.
Wow thanks for all the information. I really appreciate it
I've seen the old switcheroo in the jewelry business, the music business and the pawn shops.
6th. Get good with a file.
When it comes to consumer products, a chainsaw is the most dangerous and misunderstood device available to the general public. Unfortunately, the average consumer gets their first lesson in how to use one when a major storm blows thru. They either can't afford the price and/or the wait for a professional tree service or quite possibly (Depending on the size of the storm) can't find any to do the work. Some are hit by the "Good idea" fairy and she whispers her famous quote in their ear "You can save LOTS of money and time if you do it yourself! Besides, how hard can it be?"
When this happens, they drive to the local big box store, buy the cheapest saw available and then get to work. Most will not read the instructions, pay no attention to the directions about proper maintenance if they do, dump gasoline in the tank and start to yank on the pull starter. About 50% of warranty returns that happen within the first 30 days of purchase are saws that "Just won't start". Well, If you don't follow directions, they are right, IT WON'T! The other 48% is divided up between idiots that 1-use straight gas without two stroke oil and seize up the piston or 2-use drain oil or none at all for the chain and burn it and the bar up locking the clutch or 3- cut into dirt and rocks within 30 seconds of first use and/or install the chain backwards then claim the chain(s) it came with is junk and doesn't cut. Less than 2% are actual product defects.
Even doing simple things like reading the directions, adjusting the chain tension or cleaning the air filter take to much time and people these days are just to busy for that stupid stuff! The ignorance of some people is great job security for the local hospital emergency room and lawyers too. If the saw they just bought removes part of their leg, it couldn't possibly be their fault right? It has to be a faulty product? I bang my head off of the wall whenever I see a video like this and feel very sorry for any professional that repair saws for a living. I sometimes think that owning and running a chainsaw should require a license. IMHO it is just as dangerous when driving a car and you need one for that? Anyone with some common sense can probably use a chainsaw but its quite obvious to me that some people do NOT have it or apply it if they do?!
NEWS FLASH: Chainsaws and their operation along with cutting down trees is dangerous. If you are not sure about using one, hire a professional or get help from someone who does understand how they work. This will help you keep all of your fingers and toes and both of your legs a little longer. Rumor has it your quality of life is much higher with them all intact?
Thank you for the comment
In Sweden we actually have a license for operating a chainsaw (mandatory for those who want to use it professionally) voluntary for all others.
In any case a cheap insurance.
@@jobrell That is good to know! Politicians with actual brains and good ideas do not seem to live in this country? Besides, if any classes were given to the public here in the USA? The very next person from the class to harm themselves would immediately hire a lawyer and sue the instructor for "Bad teaching practices", as once again, it couldn't possibly be the fault of the saws operator Lol
So true what you say. I have been a professional logger for 43 years. It's scary and entertaining at the same time, these noobs with a chain saw. Some can't figure out how to release the chain brake. Which may be a good thing. 😊
‘I’m not gonna blame the person who swapped out wrong size chain’…
Yet, it is 100% their fault!
thank you Pip Pipster
Classic "know it all" dood tip; torque is higher closer to the dogs (spikes at the base of the blade) instinct is to use a sawing motion to cut, but on a chainsaw it's not necessary as the efficiency of the tool is closer to the motor on the blade. Old chains = blades like you mentioned. And trying to cut through knots will always wear out the chain faster. Cutting downed branches depending on the weight tension usually cut better bottom of the branch up (thicker than two wrists depending on the species you'll probably what a small facecut) and perpendicular. Usually new chain buys for our crew are when they get too stretched out. The labor/time sharpening with a hand tool could not be worth it in the field. Usually for larger projects, we each get a few chains when we go out, the have to sharpen them if not managed properly with time. Just picked up a pneumatic sharpener, have yet to use, hopefully with reduce time spent. I know we'd all rather have a proper break than just sitting sharpening each tooth. Initially was thinking you'd have a bent blade, till you mentioned the chain was on backwards; shark fins go towards their prey. X)
Thanks for the vid.
Thanks for the comment and information I appreciate it.
yeah, for 5 years had my husqvarna 460 rancher (not cheap), yet recently my chain keeps losening when not even cutting wood. Replaced the sprocket and spindle bearing (even though I didn't need to) then I saw my clutch kept coming lose, but not completely, when it is supposed to tighten during operation and chain break. went through 2 chains each costing 65 bucks, had 2 links installed for 32 bucks (too pricy I reckon, only had just found out about chain breakers and pressers/joiners.) If the chain is operating in an uneven direction, it wears down the rivots in the drive links and eventually lengthens the chain overall, just make sure the sprocket is good, bar is normal, and cut straight.
very good advice
I did throw a chain on my chainsaw but couldn't re use the chain as it took too much damage. Replaced the chain and it worked fine.
That's probably the best thing to do. Thanks for the comment I appreciate it
I bought a new MS 261 Stihl commercial saw because I couldn't find a good mid size saw but not because of a chain. Between it and the 440 Magnum I needed a smaller saw..........which my son-in-law ended up with. It's a tiger and all the power company guys use them. I also did away with the chain tensioner on my old Super 45. Just loosen the cover nuts, pull the bar out to the right chain tension and tighten the nuts while holding up the bar. That was mandatory on the old saws. And take the drags or depth gauges down on your chain with a flat file 3 or 4 licks and it will CUT! Thanks and Blessings!
if you got rid of the tensioner, you'd have to use the same method after a few hours of use then?
@@HomeGaragechannel Just depended on what I was cutting and yes, it was the same every time. I could be done before the others could get to the tension screw. Just held up the bar and snugged down the nuts at the same time. No problem to get used to. I kept bending the screws so I just eliminated a problem, so to speak.
if it works, keep doing it, nice.
@@HomeGaragechannel I have to. Too goofy to change or maybe just too stupid. Probably both!
A sharp chain makes life a lot easier. I've bought chains when I should've figured out how to sharpen my chains properly. Between this video and the sprocket replacement one, I SHOULD be able to fix my issue. It IS pretty worn, but I think I'll count the number of links first.
you got that right!
was working on my fathers ancient homelite xl10 automatic and it was a bear trying to find a 42 tooth 10 inch chain for it. found one in the UK for a great price.
wow, you had to go far from that one.
A good chainsaw shop will be able to make you whatever length chain you need so long as they have the correct pitch and gauge chain in stock.
Something not mentioned here. I have several saws. When we first got a 36" bar for the Stihl 390 we could not keep the chain from jumping off. New bars, new plastic guides in sprocket cover, new chains, no help. I noticed that some pro models had a "closed" sprocket (rims on both sides of the teeth to hold chain entered on sprocket). Dealer assured me that would make no difference. I replaced the stock open sprocket with a closed one anyway and MAGIC! Stopped throwing chains. There's a reason the pro saws have closed sprockets. It was never a problem with shorter bars, but if you need the longer bar (we were cutting huge stumps) just get a closed sprocket.
thank you for the information
My chain sprocket was worn. It had 1/8" marks in it. My chain wouldn't stay on 2 minutes. I replaced the sprocket and bingo problem solved. I couldn't find any info on this relationship so i wanted to put this info out there. This fixed a big problem. I was about to buy a new saw when this $10 fix solved the problem.
Thanks for sharing
Just cause you asked, yes I have had a claim problem that's so frustrating that I buy a new saw. As a matter of fact I'm having one right now, which is how I arrived at your video
I completely understand
You missing the clip that holds the adjustment screw
Thanks for the comment I appreciate it
the guy that swapped out the chain, putting the wrong sized one on and reinstalling the adjustment hardware incorrectly is 100% to blame. come on, now.
I would count the links in each chain. If the links are the same size, I would remove any extra links if you want to fix it on the cheap. Probably a better fix would be to replace the chain or chain and bar together. If it was a shop that sharpened the chain, I would take it back to them and let them know that the chain that they put back on the saw has more links than the one it came in with.
I wouldn't go back to that place.
Yes to the chain question! I could tell after buying a used Echo saw the chain was worn. I have quite a bit of work to do for my company as tornados have absolutely ripped through my state within then last several months and there’s been lots of cleanup happening. Got an Oregon Advancecut bar and E70 chain combo from lowes on sale for $35. Keeping my old echo bar and chain as a backup and to practice my chain sharpening. Being a firefighter as well, I know first hand a chainsaw can make or absolutely break your day. Anything small engine is absolutely worth at least a decent investment if you’ll be using it somewhat frequently. Absolutely LOVE this chainsaw so far though! (Echo CS-590 that was only used once or twice. Snagged it for $200 under retail!)
very nice purchase, and thank you for your time.
I came close to buying another saw but discovered the tension nut was not working properly so fixed that and chain stayed tight. Still frustrating for sure.
Good work. It's hard to deal with frustration sometimes. Thanks for the comment I appreciate it
#1 the chain needed lifted /before you tightened the nuts! #2 yup- needs sharpened + needs rakers cut down! Did you see the small /thin wood shaveings.. ? RAKERS !!!!
Thanks for the comment
I like how after you fixes it you demonstrated after I would like if you did this in your newer videos please
makes some sense
This is one of many reasons why i sharpen my own chainsaw chains. But he should of noticed it had too much slack in the chain when he put it back on the saw.
You are correct but I'm guessing they didn't notice for whatever reason. Thanks for the comment.
He was most likely dumb as fuck. I work at Home Depot TRC. Every time a chainsaw comes back, I replace the chain. Chain tension should be where its taut and when you pull vertically on the chain it goes back home.
^_^ Thanks for sharing. I sure do enjoy watching you work. Looks like someone got all bent out of shape with this saw.
I believe you are correct. This was being used a lot so hopefully it lasts them for awhile .
@@HomeGaragechannel I can read between the lines. I'm sure it'll last.
I believe it was either that the chain was stretch,ed past it,s limit,s or the chain had one or more drive links making it to long I have been there did that
I believe you're right
Lesson #1: don't let other people work on your equipment
I totally agree with you.
My #1 TIP: The most expensive pair of chainsaw chaps, that heavy duty apron your wear over your cloths to give you some protection, is less expensive then the least expensive trip to the emergency room.
Very good tip. Thanks for the comment I appreciate it
I don't normally brag expensive trips but I just got back from the gas station it wasn't a very fun trip but it was expensive. I didn't even stay overnight.
@@tonyhartness2123 let's go Brandon!
Dangerous mistake, if you don't know or are unsure, get someone who knows and is competent on how to do the repairs. Chainsaws are one of many tools that will injure or kill you in a split second!
Throwing chains can be fatal,
agreed
I think you did a great job cutting those tree branches
thank you Logan Seefeldt i appreciate your time
@@HomeGaragechannel do you think you could give me a shout out in a video
@@loganseefeldt1880 I don't do shout outs in my videos.
@@HomeGaragechannel could you start
I would fix it. I know it's tempting to buy a new one, but I have this mindset is to fix it even if the parts will cost you half the value of your machine. This kind of thinking makes me take better care of my tools.
that is a very good point. thank you QuickSqueeze
I.d look up or in the owners manual online if available or simply look at the clutch cover and see what the bar size to the chain size recommendations are etc
thats a good idea
I'm really loving your videos, I've had a proper binge over the last few days. Can I ask, what do you think would be the most likely reason for a chainsaw to keep losing tension on the chain? It's a McCulloch chainsaw and over than constantly having to tighten the bar it's a nice saw. Any advise you can offer would be massively appreciated.
The most likely reason is basically a complete or partial worn out bar/system . The best thing would be to replace the drive gear on the clutch, bar and chain bar nuts and clutch cover. Basically it's not cost effective on most chainsaws to do this so it better to buy a new saw.
@@HomeGaragechannel Ah thanks for getting back to me, I guess it's a parts chainsaw now then lol.
@@tresben6758 I would probably use the saw but in a limited way since it requires adjusting. I have a saw with the same problem so I'm just going to do just that.
Hold the tip of the bar up when ajusting the chain and tighting the bar nuts.
I've got a poulan with the single knob tigjtner. It keeps getting loose and the chain comes off the bar. I have another Wild Thing that's at least 10 yrs old, still runs like a champ. It was a trash pick with a case!
wow amazing. Do you have a part number for the single knob chainsaw? Would like to familiarize myself on it.
@@HomeGaragechannel I have to find it. Will advise.
@@HomeGaragechannel I got it out of hiding. I'll send pics, but to where.
Jim
a picture isn't necessary. Is there a model number visible?
Home Garage yes, it’s been sitting a while, fuel lines went bad. This thing is a huge PITA to put new lines on.
Here’s the mod # PP4218AVX, 42cc engine. Poulan Pro. Made in 2007. There is an 18 in Oregon bar on it, the chain is correct.
Maybe I’ll fire it tomorrow.
Chainsaw chains can be quite difficult to sharpen, so I don’t blame the person who swapped it
you are completely right.
Biggest thing. Never ever cut with a loose chain even if it’s only a couple cuts. I cut with a loose chain once and though to myself it’s only 3 cuts why not then the chain popped off and almost took my balls off. Like it’s grazed them. Not to mention it can literally slice in and cut an artery in your leg or anywhere it’s not worth the risk when you can take 1 minute to fix it exspecialy since your gonna have to do it the next time anyway
thank you for the tip
Stand on the left side of your saw keep your head out of the kickback zonealso lock your left arm and keep it locked do not bend your left arm
thanks
This video is off the chain!
Nice man. I appreciate your comment
I have a husq rancher and it's frustrating as hell, I have an extended bar and the correct chain, but tension seems to be a constant issue... and I think I'm doing everything correctly, but I doubt it's the saws fault.
Have you looked to see if the drive gear is worn out?
@@HomeGaragechannel looks good, it's a fairly new saw that doesn't get much use. I'll double check the teeth condition though. TY!
@@HomeGaragechannel its the 460 model, if that matters
@@vipergtsmre no problem
@@vipergtsmre I'll take a look
Do you know why the crankshaft case it's flooded with petrol?🤔
sure, the carb or the fuel line is leaking.
@@HomeGaragechannel the fuel line it is good.. probably the carburettor..I only change the diagram..no cleaning... I'm going to clean the carburettor and I do have a full kit replacement..
that may not fix the leak but give it a try.
Ok I’m think I’m going to replace the chain.
This is my first time using a chain saw. After some use the chain popped off. I reinstalled it but it keeps popping off so I think there’s been some damage and I need to just use a new chain.
These things are the horses of hardware. Powerful machine on glass legs. 😂
Do I need to oil this as I use it? Do you have a video on cleaning, maintenance, when to replace the blade etc?
Thanks
since I don't know what kind of chainsaw you have, I can't really say. Also you might consider inspecting the clutch drum for wear on the teeth.
@@HomeGaragechannel I have a Poulan Pro 42cc PP4218AVX. I should have been more specific. I was wondering do I have to oil the chain. I did change the chain. Cutting has been a breeze and it has not thrown a chain. 👍
nice, and no you don't have to personally oil the chain because you're supposed put bar oil in it and it's supposed to do it automatically
I get sick of the chain coming off my chainsaw. And when I put the chain back on the saw it just never works right. The chain doesn't even want to turn. I put it right back on the The motor but the chain is frozen. So I am frustrated I hate trying to deal with it.
is the chain brake on?
When you finally started cutting, your chain was way too loose. I could see space between the chain and the guide bar without you even pulling on it.
you're absolutely right.
Thanks for sharing. I have two problems: 1. The chain throws off every so often. 2. When the chain comes off I have an issue putting it back the right way.
Thanks for the comment. How long has it been since the bar and chain was last replaced? Also inspect the drive gear on the clutch for wear from the chain.
@@HomeGaragechannel Thanks for the inquiry. I have never replaced the bar and the chain. I clean and make sure I have oil in the reservoir
@@VigilanteMian how old is the saw?
@@HomeGaragechannel This is an electric saw. It is around seven years old. I cleaned it today and made sure the tension of the chain was as you showed in this video. This time the chain never came off.
@@VigilanteMian excellent. Just keep checking the bar nuts are tight before you start using it.
That chainsaw has minor problems however fixing the chain as it is to long you do not simply do as you do a bike chain.
First look at the drive sprocket and sword sprocket as they tend to wear out.
yes you are right, the drive sprocket is the main problem
Wow those theets must have been blunt to oblivion. It really was kinda painful to watch.
Thanks for the comment
Awesome fix as always😍
Thank you for the comment I appreciate it
Sorry, at 53 seconds in to it, the chain is on backwards. Think that might have something to do with it ?
I remember now, I asked them about it, and they said they hurriedly put the chain back on that way.
1. What about the number of drive links:
My original Husqvarna chain (the chain that came installed on my new 20” Husqvarna 455 Rancher (56cc engine) chainsaw when I bought it) has 80 drive links. I was sold an Oregon 20” “Powercut” replacement chain with only 72 drive links. I never had the Husqvarna chain come off the bar, but as I had the saw turned sideways (cutting a stump to the lowest height), the Oregon 72 drive link chain came off the bar; I had this happen twice, with 2 of this same type of Oregon chains. Is the lower number of drive links affecting the chain to where it can come off of the bar more easily? Why the difference in number of drive links?
2. Also, when the chains came off the bar, the drive links got “roughed up” a little with jagged areas & small spurs on them; is this chain reparable in this condition? I tried filing the “uneven/ rough areas” of the small “spurs” on the drive links themselves in order for them to fit back into the v slot on the bar, but they still hung up in the bar’s slot & wouldn’t glide smoothly down & thru the bar; I figure they are bent to one side or the other and that the chain is most likely ruined. In your opinion, are these chains ruined when the drive links get mangled, bent, & will not fit, nor move smoothly thru the slot in the chainsaw bar any longer?
Thank you for any info that you can provide me; still learning & trying to get all this stuff figured out! Great video too by the way!!
I do apologize as my main area of interest is mainly getting small engines running but I'm not a specialist when it comes to chainsaws. Where did you buy the saw and the extra chain?
@@HomeGaragechannel ah no worries. Bought the saw at Lowe’s & the chain at a small local business that use to be a Western Auto (but now is no longer affiliated with Western Auto). The business sharpens chains, works on small engines, etc.
The Husqvarna H80 chain has 72 drive links not 80. New chains will stretch a little and will need the chain adjusted after initial use. A sloppy chain or a chain misalignment will cause a chain to come off the bar.
would you file the tips of the chain to make it fit the bar better
I guess you could in a pinch.
should i replace the bar and chain
yes , it would be a better solution, also, how used, is the chain?
the chain is new but when it was spit out it put burrs and some tips are gone
ok will do ty
Always good videos sr !!!!!
Thanks for the comment I really do appreciate it.
I have same problem
My chain keep stretching
Hasn't left my workshop ever
It's a stihl chain on cheap chainsaw
Kept tighting but after some use its loose again
Until the point that I had to to drill new hole on plate to keep tightening the chain.
Its doing my heading
Plate can't shrink
Chain shouldn't expend, it's a stihl , even if was some cheap one shouldn't move
So if someone has any idea why it's happening and how to stop it, it would be appreciated
Thanks
look at your drive gear on the clutch, I suspect it to be worn, try replacing that.
Dude, chains stretch and wear. Bars wear, sprockets wear. You have adjust the tension once in a while to keep it tight.
Did you put chain and bar oil in the saw? If the chain is so stretched that you need a new hole in the bar for adjustment then the chain is worn out. If the chain keeps stretching it's going to break and you don't want to experience that when the chain is racing around the bar at full speed.
You needed to show how much tension the chain is supposed to have!! :(
That's a good idea
So something is really wrong with mine it runs great but when I start it up the chain keeps giting lose and fall off idk what to do I don't know if I need to find a new bar or chain
I would replace the bar and chain and inspect the drive gear on the clutch
Thanks you I had my friend look at it and he said the chain I just bought and put on it last week was bent I only used it for a day and the chain snapped I guess some are just made crappy
I guess so.
I got a question for you about a mini bike hope you can help me with this got a 212cc motor from harbor freight and I don't know what type of clutch I need can you help
There are plenty of centrifugal clutches sized for #35 chain on Amazon.
This Is The Old Poulan PRO Chainsaw?😐
Thank you for the comment I appreciate it. Yes I think so.
I'm the sort of person who would have to fix her up !
I was pretty sure of that. Thanks Russell Booth for the comment I appreciate it
So what did you do with the other sharp chain? Really does not help if I do not have an old chain. Go buy another chain?
I don't recall what I did with it,
I wonder why so many folks buy a too big barred saw. I have 2 husqvarna"s, 40 cc 15inch and 60 cc 18 inch. Any tree in Spain no problem . You yanks would stick a 24 inch on the 60 cc making it rubbish
LOL>. yes sir.
The most obvious problem I can see, is the saw is a Poulan!!
LOL!!
Why does my chain cut the sprocket? Is it too tight?
it could be too tight but the sprocket needs to be changed as they don't last forever.
@@HomeGaragechannel i changed it and this one is getting the same way. Thank you for your response. It also kicks the chain off. Im thinking the bar is not the one it calls for. Someone replaced it. Btw i bought this echo at the pawn.
@@Rustybajostrings okay it could be a combination of several issues from the chain to the bar. Is replacing both an option for you?
@@HomeGaragechannel i am going to do that. Thanks Sir.
@@Rustybajostrings no problem
I posted a vid of my riding mower that won’t crank I think it’s a starter can you check it out and verify if I’m on the right track
Yes I will.
If I send it out I mark the bar and put paint on the chain.
I got burned once, never again.
Nice job
Why wouldn’t you blame the person that put on the wrong chain and backwards? 🤔
because what good would it do to blame them?
What kind of chainsaw do you like I like sthil
I had to go out and buy one I would choose Stihl.
Cool
I would tell the guy that does the chain to get it right or get into another profession
good advice.
I dosen't bother to sharpen my chain. When it gets dull I buy a new 1
perfectly fine
Hey there. I am getting ready to demolish an old camper. I was wondering if anyone knows if there is a demolition chain for a saw. Something that can cut through nails, aluminum siding, and wood. I could use a saws-all. But I'm looking for something I already have and gas powered. It's parked out in BFE. I suppose I could move it. I don't know. I was hoping to get a manufacturer for a demo chain. Because I can't find one. Any help would be appreciated. Thanks
Dangerous
Yes very dangerous.
no not at all
Thank you for the comment I appreciate it
This guy made too many errors for me to list! He wouldn't repair MY saw!
👍
Thank you
Can you show your face in one plz
One day perhaps when theres a need to.
