- Did I get a good deal? I think so! Many repairs needed to make it fully functional again, but didn't cost a lot of money in parts. I go through the problems, diagnosis, and the fixes.

Since the platform has trouble communicating to ground controls, you should name the lift Major Tom
Perfect 🤣 😂
Every time he said, "Ground Control", I sang "Major Tom." Made me chuckle.
@@berthongo8531 "your circuits dead, there's something wrong, can you hear me Major Tom?" LOL!!!
Lol, I was thinking the same thing
Up in the sky ...
... and the stars look different today ...
I must say, I love all of your videos but these ones buying and fixing heavy equipment have been the best. The Johnson was pretty great too but not there's nothing quite like machines that weigh as much as a small house.
A single-wide mobile home, arguably the lightest thing that qualifies as a house, is about 60,000 lbs.
As someone with a lot of experience in boom lifts, being tied in with a harness whenever you are in the basket is a must. I have watched people get shot right out of them, once without a harness during offloading when a wheel slipped off the ramp. Fortunately he landed in a large pile of fresh soil that was just delivered, and was only bruised in body and ego. And the other time his harness caught him and kept him from hitting the concrete from 20 feet up after he was launched out while moving it and hit a speed bump.
Always be on a harness even just playing around with it!!!
Even with the harness I imagine you would be messed up pretty bad when this thing flips with you inside.
A harness is an absolute must with these machines. I got bounced one time when the machine hit a 1" drop and only stayed with the basket because of my harness. Without it, I would have had a 30 foot drop onto asphalt, and I don't think that would have been a fun ride.
Having been in the equipment rental business and renting all sizes of boom lifts, I was horrified to see you not in a harness. I saw far too many deaths in booms when people got thrown out of boom baskets w/no harness. Folks, PLEASE wear a harness!
@@warbirdwf
Not just wear a harness, but make sure you know how to, and do, adjust it properly, then make sure you are clipped in properly, and work with someone who can initiate rescue if you fall out. A harness will not prevent injuries, and one can die just from injuries received from the harness, an improper harness adjustment, hitting objects while falling, or from suspension trauma. It is no joke, and most people have people who depend on them to come home alive.
You're hard working man.
Hope this machine will serve you for many years to come.
Best wishes .
Greetings from Slovenia EU
I don’t find myself laughing out loud watching you tubers, but “it didn’t do a darn thing” did the trick. Love your sense of humor. Thanks. good thing Ilm not your neighbor, not that I break things, but I would sure love to borrow them.
I love your videos, not just for the ingenuity and skill you display in them -- primarily it's your determination to get complicated things that require a lot of patience done, and done well.
THANKS!
At our age we are sometimes in need of a little lift. Cheers 🍻😁❤
I work as an electrician for Grede's in Reedsburg WI and these types as well as scissor lifts to get to some of the huge motors for air circulation & dust cleaning, transfer ladles, and to get to lights... I would use jlg lift that was 120 ft tall to get to the stacks to change out heat probes that got melted, but still ended up having to use the attached ladders to get to probes that were 3/4s on up to the top... Really sticks doing it in winter, your azz really froze at the 200 to 250 foot range!!!
My guess was 10-12,000. Figured as much as a smaller old tractor. Nice job!
PS please get a harness, don’t get yourself hurt.
All the riggers who used lifts at the plants I’ve worked at used harnesses religiously. I knew those guys pretty well. If those stubborn maintenance guys used them they probably saw someone get hurt and or die.
I highly recommend using a safety harness while operating your boom lift. I'm saying this after working on several different types of lifts, the boom lift can act like a sling shot and catapult you out of the basket. Stay safe and keep on posting more videos.
Ultimate vicarious living for an over the hill Mr. Fix-it.
You hooked me with your outboard series and I've been watching everything else you put out since please keep up the good work.
Just a note to say how much I appreciate you using both sets of units in your videos, I mean it’s not a major thing it’s just a nice to have, but I know it will no doubt take a bit of time and effort and it’s appreciated by those of us in metric land 👍
I really like how you are able to solve the problems that your machines come with. Great content too!
Its always nice, when you struck great deal buying equipment, but it's even nicer when you find how useful it really is, after you repair it yourself. Than work become real fun :)
I learn a lot about problem solving from watching your videos...Thank you
You sure know your electronics. I loved this video l was glued to it start to finish.
I really enjoyed your video on the dump truck. I hope you have more videos on the truck and man lift!!!
The sheriff should be visiting you soon! You stole it! Great find and a great video. Thanks for sharing it with us and takie care!
I worked in a Steel Mill for 35 years. The day we got these Man Lifts in was a Blessing. We would use all sizes of these JLG's. Glad to see you got it working. Get yourself a safety harness just in case you never know what might happen. Check you main cylinder that lifts you, see if you got a leak. 10 grand. Wow, you did get a good deal @ 8 grand. Good Job.
Boom lifts are just one of those things that are amazing toys. There's something special about being on a machine that moves you around, and brings you to places you normally can't go. $8000 delivered is a steal IMO, I would've guessed at least 20k. It also looks like a very decent machine. For a machine that's pretty much guaranteed to be outside without any kind of cover its entire life, everything looks really good.
I'm wondering though, did the lever controls ever go back to being an analog input again? It still seemed like at least the up/down function was still pretty much an on/off control, instead of an analog slow/fast input.
(There's a point to this longer story at the bottom)
I personally ran a machine very similar to this one (but a lot more modern) on a construction site as an intern about 10 years ago. I loved every second of it, but it did almost kill me once. Well maybe not kill, but it definitely scared me. I had to drive it along a street for a bit, where I encountered a speed bump. I knew that was gonna be sketchy, so I slowed way down. First axle went up, basket came down, all controlled and well. Same for the second axle. I started turning the corner, no traffic in sight. As soon as I was in the middle of the intersection, traffic came from all sides. Young me felt at least a little bit of pressure to get moving quickly, since I probably wasn't supposed to be on a public road with that machine, so I sped it up a bit. The second the first axle went down the speedbump and the basked shot upwards, I knew I made a mistake. Thankfully, it only launched me about 2, 3 feet, and I was able to hold on with my hands, but it scared the shit out of me. Of course, I wasn't wearing any safety harness, because I was a dumb intern, so it could've gone worse.
I also saw the tilt (leveling) function on the basket break once while somebody else was using it. They were up almost vertically, so when coming down the basket was pretty much horizontal. That would not have been fun if the guy hadn't been wearing his harness.
The point of the story: I'd take safety seriously in this machine. I know how safe the basket feels, but like you explained with the tire blowout example: A small movement at the ground translates to a LOT up top. Given that this machine will be running on "rough" terrain, and not just a concrete warehouse floor, anything can happen. Nothing will happen 1000 times, but the thing is: it has to go right every single time. It only has to go wrong once for you and your family to have a very bad day.
I use to run one too. I would definitely advise to get strapped with a harness. These things can catapult you out of the basket fast!
Yeah, my first thought was 20k as well.
My guess was 5 grand plus another 5 for delivery, especially considering the incapability of lifting from the first minutes. That'd be about the scrap value I guessed.
Hah. Would you believe I took a stab at 8 grand then thought to read the comments. Imagine my surprise when I read yours.
I have absolutely no use for one, but yet I want one because………….. Ya never know. 🤷♂️.
I remember back when my brother bought his first bucket truck for his company and how that absolutely transformed gutter cleaning and power washing on the family's various properties. Now THIS is a whole nother level. lol
The "quick open" on the new potentiometer was entirely due to the resistance exceeding the range the meter was set to, just before the auto-ranging function kicked in. It was not actually an open circuit on the pot.
Exactly, you really need to be able to manually set the range to measure potentiometers accurately.
I thought I only needed a d4 and back hoe for my window box but now a boom lift is on my bucket list. The way you explain things is perfect for a 76 year old ex FAA air mechanic/ council employee, Keep them coming
You done well. Being a certified JLG technician, most the time repairs are not done properly and the wiring has been hacked. You got an easy one to get back to working condition.
Did anybody else fight the urge to say "to major Tom"!? 😂
Love your knowledge and all your videos! You're awesome!!
Man that was a series of minor and major wins all the way round.
I wonder if the guy who sold it watches this channel and is now sitting there, eating his heart out. Excellent job!
Fun fact: the Blackhawk service manual requires an analog Ohmmeter to check the potentiometers. There are very few tasks for which analog meters are still useful, but I guess smooothness of controls is one of them and that's why Simpson still makes them. I just use a scope.
Wow! $8000 is a screamin deal, especially with only needing relatively minor fixes. I guessed somewhere around 12k-15k.
You did get a real deal on this lift. You did a great job fixing it too.
It brings me joy watching you take a big chance on a piece of equipment with some issues and with some effort you get a nice toy at the end.
If you think it's intimidating at 80' on a calm day try with a nice solid breeze making the basket sway more than a foot or two in either direction
A simple first aid kit (tourniquet, field dressing etc) would be a good addition to your kit in that boom especially working with things like saws. I'd hate to have to wait for the trip down while bleeding. Love the videos and commentary. Thanks for sharing!
Thats a great deal. I guessed double plus transport. Love your work too. Keep the videos coming 👍
When you say: "It's gonna be allright" I tend to agree. When another guy over in another machining channel says the same thing, I think : What a hack, way to do things half-way.
I really enjoy watching you repair things. I learn something from every video.
When you asked about the price, I was thinking "$20k... no, it probably wasn't that cheap" I spit out my water when you said the real price tag
Same here i said to myself "had to be at least 20k" and when he said 8k i started considering looking for one myself 😂
I hope you are saving all the fire wood for your fire this winter, “waste not want not”. I must say I came across this video by complete chance and I enjoyed it and found it most informative more than I can say. I have always wondered how these cherry pickers worked.
I think it's an awesome deal! What you would have to pay tree surgen.. SMH. Plus everything else you need.. I've always appreciated your bids. It reminds me of a life I used to live on a personal property and as a property manager for someone else. Thank you for what you put out there, man
Can't wait to see what other machines and tools you buy and fix/restore.
Exelent job, Mr., you did a real saving on repairs, but also got lucky that the errors were relatively easy to fix. Like the spring in the stash was exactly what you needed. Well, we all (diy crafters) spare a bunch of stuff, parts and pieces, but when time comes, we actually (in 98% of cases) need that something we don't have. So, very lucky indeed, also with potentiometers.. =) It's a good thing it was like that and you dealt with it. Keep on, cheers.
Don't you love it when a huge problem can be fixed with a couple small tweaks and parts. What an awesome machine that is now fully functional just by giving it some tlc. Thanks for sharing! Keep up the good work.
Great video with nice camera views. You are a great teacher and explain what you are thinking and doing so we can follow along with you. You are a patient guy and make great videos.
Man that’s an awesome lift for tree work!!!! Twice the size of what I want!!!! Killer tool!!!
I worked a job a few months ago & had the pleasure of using a lift. Fun, a lot of fun. However, during those three days in the lift I had thought many times that I would trust the telescope feature more if I understood how everything worked. Job completed with no injuries. Now that I have found this video, I will be more confident in the lift. Just a few minutes in & I love how you are describing the hydraulic hoses. Explaining how the oil is diverted to cause the lift to slow down & not just drop if a hydraulic hose burst unexpectedly. Looking forward to the rest of the video now. Just wanted to get my comment out before I forgot it 😆💯👍😎🤠
Love your trouble shooting procedures. Very logical and thorough.
Screaming deal! Really like how you put your videos together, been watching for some time now. Your attention to details do not leave very many unanswered questions. My guess was $18,000.
For some reason call it curiosity I'm very Interested in watching you make this boom lift look and work like new again if that's your intention good luck and I'll be watching and waiting for video updates
Back in 1980 I lived on a mate's 240 acre farm in Bakers Hill, Western Australia, I was 20 Jeff would have been about 24, like what you get up to, and though different on Jeff's farm,
it was the ingenuity of not having availability of anything you need nearby,
remember when the Internet was NOT Part of your life at all? and you had to invent,, find, cobble together, adapt to
and basically have to used your own inventiveness rather than open google and cheat.
That year of creativity changed the way I looked at life, started using Lateral thinking eventually started putting a person who put those words into book form Edward De Bono certainly has some excellent reading. I have a huge appreciation of what farmers skills are.
Your videos remind me so much of those days,
Long is the time gone where
People mostly look within for an answer and reach out for a search engine.

Great price delivered, nice troubleshooting and good repairs. My price quess was 10k.
You do know when moving the lift if basket is just clearing the ground, the speed is stuck in low.
Raise the backet to about 15-20 feet, you get a good view of your surroundings, and high speed drive is enabled.
About twice as fast as slow.
Operated these and also electric lifts during my years as an industrial Electrician in a large shipyard.
I always hated the harness, but they were required by employer.
If I was on my own, I wouldn't wear one.
Great video. I learned a lot. Not that I have a repair I need to make, but the troubleshooting, process of elimination of was fascinating. Never thought I'd be so captivated in heavy machinery repairs. But I love a good deal, and the ability to repair it yourself has always been appealing.
I REALLY enjoyed this video! I have always wondered about how these lifts worked.
Thanks for sharing.
Stumbled across this somehow on my RUclips recommended. I work on these lifts in the UK (admittedly a lot newer than this) - really interesting to see how they used to work and what similarities they have today. Enjoyed the video.
8k is a steal. Love the channel. You are intelligent and quite informative. I appreciate that. Thank you sir. Will definitely be looking for the next video.
I drove this same exact boom lift for years while iron working on ft Benning georgia building the barracks. Great fix on the switches and everything!! VERY well done I love it!!
Ahhhh my friend! You did something I learned to do years ago….. sometimes….when you are working in a very tight confined place where you can’t see anything….. it’s actually better just to close your eyes and form a mental picture of what you’re doing!!! It actually works!!!
I wish that I had bought one that was for sale locally to me. I could really use one.
Having worked on boom trucks in a different life I can say that the explanation you gave about what happens if a hydraulic line breaks may or not be partially correct. Generally speaking the cylinders are controled through the control panels but, if a catastrophic break happens to the lines, there is a valve that needs to be supplied by hydraulic pressure to enable the cylinder to retract. The fluid is cleverly routed through the valve with check valves that require pressure to enable the valve to release the cylinder. In another line of work I have been stuck in a manlift for precisely this reason. Not that a line broke but because the cylinder had reached it's max travel. The machine had been bouncing some and the control circuit could not overcome the pressure spike that had occurred in the system thereby stranding me and another worker for an hour. Eventually the tech who came out figured it out.
And I agree 8K is a screaming good deal.
Sitting here in Sweden watching an American farmer, and i must say great channel ! the gun vids brought me here but i stayed and subed for the variety
I agree, you got a great deal and you are very talented making repairs on everything . Congratulations on your purchase.
Wow, what a screaming deal! I follow a guy in France who’s looking for an 80 footer, just sold his 55. He uses it for the roofs and spires on his chateau and has just bought an old 1700’s nunnery with an even taller spire. Very through diagnostics there, totally worth all your time! What a handy machine to have.
Great video, really interesting. Thought the camera and sound was perfect. Please include and addition work you carry out on your various machines. Best wishes to you and your family. Best wishes from the Potteries of England...
Basket lifts are so handy. I owned a 60 and 80 feet years ago through my business. We used them all the time for projects around the farm too. They are great for tree work. You can go to the top of a large tree and take it down one small piece at the time. You definitely got a great deal on that machine. It makes me want to look for a used one like that that needs a little tlc in my area.
Ladybug sighting: 25:00.
I guessed $15,000. Well done!
Great video, the pacing was perfect! Beautiful shot and property at the end.
Started watching your video's a few weeks ago on cutting down trees. I've learned a alot from watching them. I think the canvas idea was genius. Keep up the good work.
Another reason they sell pretty cheap is that they always have gremlins that are hard to troubleshoot, but you handled them likity-split. Great troubleshooting! I think you should name it Tre, as in Trebuchet (they scare me). Thanks for the video!
$8,000 delivered!!!!!!!!! You didn’t get a screaming deal! You stole it! Wow I’d love to find a buy like that! Love the Chanel btw!!!
You’re having much to much fun! Things get a bit white knuckle from way up there….haha. Just glad you got such a great deal and know you will be putting it to good use around your property!
You should possibly add a shutout switch that prevents operating when the door is open - it might be quite easy to add a Normally Open switch into the line of the paddle lockout. That way, unless the door is closed AND the paddle is pressed, the operation is prevented.
Another typical operation safety is a solenoid bolt that prevents opening the door once a certain height is passed, but that is very hard to add aftermarket.
if you *really* want to go fancy, you could add a winch and a large loop under the basket in some way, allowing to crane cargo.
In order to go up full extension up and out you need to have the axles extended out all the way
What a super handy rig, that's a great find. It's so satisfying to find the problem and fix it. Thanks for the video that was very interesting
When I worked in the field, I always extended the boom fully and sprayed the entire thing (contact points) with a molly based dry slide lubricant. My guess was $12,000. You did get a screaming deal.
Having used one of these on a handful of occasions your grip on the cage tightens as you get higher and your buttocks become very tense. I think its called fear. 🥴
Pucker Time
Mine were fine all the way up, rotating etc but as soon as it was driven, it was pucker time.
Other than you NOT wearing a harness (damn scary), I really enjoyed your diagnosing and repairing that old boom lift. It was very enjoyable watching you methodically trouble shoot both the hydraulic and electrical systems on the boom to get it back to working correctly. The next video that would be enjoyable would be to fix the engine so you don't need starting fluid. You can also source good used parts for that boom like the missing wheel drive brake assembly.
Came to the channels for guncraft. End up watching repairs on farmcraft. Congrats on you acquisitions
Just found your channel.. love the way you film and troubleshoot equipment!
Extremley useful machine. Also for a very good aqusition price.
Not talking about your skills for all repairs to get it ready being useful.
Congrats ! Keep em coming my friend, i will be here to watch next episodes.
RESPECT !!
Those older variable resistors usually lasted a long time but they do need cleaning occasionally. Older radios would have them get dirty causing static when the volume was being changed. A quick fix was to spray some contact cleaner on the black area in the resistor you mentioned. Then turn it all the way both ways a couple of times to clean the contact area. Let it dry and it is usually fixed unless the resistor or contact is is broken or worn out. Contact could have worn off but that is unusual.
I love the fact that most of the problems on the lift boiled down to things needing to be tightened. The hydraulic issue, the wire harness issue, the leg switch. A few squirts of deoxit may have even addressed the switches, though for the price, it was TOTALLY the right decision to replace the potentiometers. I'm impressed you were able to source them (apparently?) easily. What a bargain! It almost makes it worthwhile to pay whatever you need to to get that last wheel drive linkage working. I'm so anal, I probably would do it just for the bragging rights! lol. Nicely done!
Just discovered your channel, excellent content, I learn so much from watching others do this stuff. That is an insane deal, it’s amazing how quickly people with throw something away rather than take a little time to fix it.
Jealous, you have so much great content ahead of you to watch.
SCORE!!!!! That's a really good deal considering how relatively little was wrong with it.
You can fix a lot of potentiometers by simply spraying contact cleaner in them and working them back and forth to clean the wafer and wiper. This most always fixes ones that jump around. Used to do that all the time back in the tv repair days. Fixed a lot of scratchy volume controls on stereos. The black material you spoke of is carbon. You could the dirty wear on it. Contact cleaner would have fixed that right up like new.
Man I’d love to find one like this for our farm! Great asset to the tool belt! Love all your videos, detailed but not overboard.
Great deal and great troubleshooting!!
Really nice score on the lift, funny how cheap it was to fix. Your meter was just auto-ranging when testing the new pot. That's why I generally avoid using auto-range meters for electronics work.
Hi bud, first time I’ve watched your channel and I loved it, it’s very reminiscent of Diesel Creek which I also really enjoy. I’m 60 this year and recently picked up a JGL man lift which I bought at auction for $600 AUD with the optional power pack. It’s light and quickly disassembles into three sub assemblies for easy transport and is very easy to move around. While nothing like yours it’s perfect for my suburban block as I can clean my solar panels, solar hot water tubes and the gutters without using a ladder. We have some ten foot high hedges and it’s great for trimming those as well. Even though you know how stable and heavy the base of your machine is I bet you still felt like it might tip over when you were 80 feet up looking straight down at it😂 Yes, $8,000 was a bargain but then a lot of people wouldn’t know how to fix it or be willing to take a chance with spending that much money without knowing how much it would cost to fix it. It’s easy to see you will get many years of use out of the lift and for the price I’d be hanging onto it. Cheers Stuart 🇦🇺
Really enjoyed this video and the potentiometer lesson. Just have to add, the same nitwits who call you insane for one-handing a balanced, lightweight, arborist saw, would also not know what an arborist saw is. Ignore these dopes.
Good deal, Buddy.
Good Job also repairing it for low budget money.
And it will save you much more in the future, my friend!
These one hand saws are nice, but dangerous.
You have one free hand to get into the chain with.
I have a MS200T too.
Tom 😎
Your repair videos are top notch. So much information and a great editing style really make for an enjoyable watch. Love these videos!
What a screaming deal! Awesome understanding of physics and phenomenon of hydraulics systems. Make sure you get yourself a good harness with nice lanyard especially since you save bank on the machine Peace
I like the way you do diagnostics. I have a pressure washer that was diagnosed at a dealer repair facility and they told me it needed a new pump. I said forget about it and took it home because the pump was valued at more than half the cost of a new pressure washer of the same make. I then decided to look at myself because it didn't make any sense when the pump would work intermittently and then fail randomly. The fix was simple and it didn't cost me a new pump and only took ten minutes to fix. I don't think they even looked at it to come to their conclusion. Luckily the "diagnosis" was free. There was a tiny amount of trash in the water line screen filter at the pump intake and once it was cleared it worked fine. Never trusting a shop that is only in it for profit is my standard practice nowadays. Still using that same pressure washer two years later.
Awsome. Thanks for taking us on the repairs. Used those machines for years but never got into the mechanics. Much appreciated. You have a excellent voice for this type of media and great explanations
Very nice work on the lift!
And thank you for videos, of course!
wow that is an incredible deal! my lowest guess was double that.
I have recently bought an out of certification truck mounted boom lift. The older ones become quite cheap here, as for commercial use its about I believe, 30k to recertify them. Anyway, on this one, its not hard to get stuck up in the air as there are a few issues that can nullify the bucket controls. For peace of mind and as sometimes working alone I have taught myself to abseil down. This took a bit to get right. The solution in the end after getting the right kit organised ( not too hard as my son is an experienced rock climber) was a small boom bolted onto the bucket . This boom sticks up higher than the bucket and enables me to hang in my harness over the side before lowering . Before this, it felt way scarier and less controlled with my attachment point, lower. 😀
Great job getting it all fixed up
I've been watching a lot of your videos over the last few days and man I have learned so much watching you fix and build stuff.
Way better education than anything I ever learned in what passes for a school, especially these days. Thanks. Still more for me to watch and learn. Keep them coming. (grins)
Just started watching your channel and I'm really enjoying your work. You're clear and concise and narration is easy to follow. Keep up the great work! 👍
So cool to watch all your projects!
Simple trick when fitting parts like this.
Use two piece's of threaded bar, one slightly longer than the other.
So you only have to line up one at a time. Tighten one with a nut. Remove the other bar out fit bolt. Remove bar and nut and fit other bolt.or just use threaded bar.
That is a screaming deal! Well done!
Awsome video!! Great to see you trouble shoot and fix all the problems!! Looking forward to seeing you use this more!! Love the USA!! Stay safe always!!
I've been looking forward to this video, and it's finally popped to the top of my queue. 👍👍👍
Outstanding troubleshooting and electrical repairs!
