Repairing restoring a Makita HM1200K demo hammer after a catastrophic part failure.

- It's quite amazing how just how long this HM1200K hammer was used for after it actually broke the impact bolt inside.
The customer continued used it for what could have been years. only reason it was eventually left in for repair, is because the chisel would not come out.
Just goes to show how well made these old makita hammers were built.

What a decent shop owner, thinking of the customer. It's getting rare nowadays that you get this level of service. Either they want to sell you a new machine or other shops would have changed you the full amount. Cheers Dean.
I think I'd give the customer the choice.... "OK, that will be €220!! Or........ €170 if you sit over there and watch this video and promise to never abuse your tools again!" 😂 I still think that the service you provide your customers is amazing as it would have been so easy to get half way through pulling that apart before just handing it back to your customer. We're all lucky that people like you still exist in our world 😊👍👍👍
A very fair price Mr. D. It sometimes seems that there are few trustworthy tradespeople in today's world.
I've also learnt to check the ends of my cheap chisels for mushrooming, when putting the tool away. Thanks.
You've saved another old machine from the scrap man. Less land fill (so to speak). Great video, Dean. Thanks for sharing.
Thanks 👍
Love seeing u fixing tools. Talented man
Nice job Dean. Great to see shop owner trying to help a worker out with the price break, or even not fixing it at all. Selling him a new one would be a far harder pill ta swallow.
I cannot be credited with that, im not the shop owner. Im just the repair man.
Its the owner of the shop here that has taken good care of his customers for the past 30 years.
He works 6 days a week 14 plus hours a day, and would never see any of his customers stuck.
Good quality is why I watch your videos! Attention to detail
Well done Dean. Amazes me how you keeps tabs on the 1000's of parts you keep in stock.
It amazes me sometime also. i cant even remember peoples names, but i know where I have a torsion spring for a Makita 2012NB thicknesser
Being straight with your customers is the best practice, they will recommend and return which is what business is about.
Nice work and commentary as usual.
There is the advantage of keeping stock for older machines.
The "just in time" mentality doesn't benefit anybody.
Great repair Dean.
My cousin's helper did the same thing at work one day. He gave the completely green helper the big hammer drill with a ground rod driver attachment in it and told him to drive the ground rods in until they were flush with the ground. It was the first time the kid had ever used one of these drills. Something broke inside of the drill and the bit mushroomed inside the housing. He asked me to look at it while I was busy, I said give me a minute but I might have to take it home to fix it. When I walk outside 5 minutes later, they have taken to cutting the chuck apart with an angle grinder and pretty much destroyed the entire chucking mechanisms of the drill. It was then that we found out that our only local tool repair business has shuttered its doors forever as most people are not willing to pay for repairs but buy cheaper equipment that is new. I couldn't find the parts online and that was the death of that drill.
I really admire Dean he is always thinking of his customers cost but tries his best to put the best in to the machine he knows his business that's for sure
Always a testament as to why to buy Makita these videos
That is an IMPRESSIVE amount of metal shavings in that grease. While you're washing the innards, I'm in awe that thing ran as well as it sounded like it did. I'm curious how long that guy ran that tool with that bit in there just destroying it as it has.. Amazing the destruction that can happen inside one of these machines and it keeps on ticking.
eventually,customer is very lucky to have you😄
10 years time that'll still be going strong
Another excellent video Dean, keep 'em coming! All the best from South Wales.
Thank you Sir!!!!!
Great channel
fair play dean... good video as always
The inside of that machine looked like the bed of my lathe after machining stainless. It was horrific.
Thanks Dean for another great one mate. Nothing built like the old tools. Love it.
Great job on massive damage. Also good onya for no charge for second hand and cost-only for NOS that you had. Customer should be ecstatic - I would be.
Hi Dean. Just discovered your channel and loving the content. Just curious, at the end of the day what are you using to get all the grease off your hands?
Wonder if a new one for 3x the repair will still be running when this repaired one will be? Sometimes this older kit is a lot harder wearing. My old kango is still plodding I’d hate to have to replace it
Great vid.
Looks like almost ready for a change of kerosene - especially after all those metal bits in there.
Can we get a vid of the change next time you do one?
Absolutely
I found that big Hitachi demo hammer, the one in the gray metal case in my dads stuff; its hardly used because dad was DIY, wondering if parts exists for that thing. Should I at least replace the grase / oil in it?
What do you use as a washing fluid? Great video as always!
Kerosene
What type of grease is recommended to go inside the bodies of these hammer machines?
100k deano got the plaque
Please make a video when you change the liquid that you use tò clean the parts. Thanks 😊
🙌
Another 20 years on work.
Hi dean do you have any tips on repairing the yellow bit on makita batteries. Can this be done easily and safely or are they throw away if theyre out if warranty.
You would have to replace the board with a copy one
Well worth fixing. Modern stuff is designed to fail and be binned
Interesting way for a cheap bit to fail, I guess it's not a problem for SDS+, maybe not even SDS max with rotary mode because they still have much less power than a straight up demo hammer?
SDS Plus: 6-7 Joules of impact energy at the most.
Demolition Hammers: 20+ Joules.
Some really big ones reach almost 80 Joules.
If you put those pistons and smaller parts in a heated ultrasonic cleaner I think the metal debris would come loose
Why don't you use a powerful magnet inside a plastic bag to remove all the little metal shavings?
Makita 40v content any time soon Deano? I look inside one if the shops sells the line and basically your thoughts on it etc etc please!
Thumbs up on this.
Fantastic to see 10+ year old machines having repairs done!
He commented that they haven't had any in iirc. Lot of em are still under warranty.
@@SlowExpensive Those were my thoughts - although if there is a man that can open a unit up to show us the makeup of say the most popular 40v tool in the line without tarnishing it and still being able to sell it - This is the man - i'm still curious if his shop in Donegal sells XGT though....

Get some heavy duty gloves for the parts washer, soaking your hands in Kerosene and whatever greasy grit is on the parts cant be good for the skin.
Plenty of cases out there where in the past people handled chemicals all day bare handed and it really did some damage to the skin and nerves.
I'm actually more worried about him inhaling vapors while using that washer, kerosene doesn't penetrate healthy skin, but is quite toxic if inhaled or swallowed and ill effects are cumulative with exposure. Some sort of transparent lid/screen over the washing station would help counter this, but would also get in the way of filming, so making such videos actually increases his exposure (personally I'd prefer he used a safety screen regardless of video image quality).
220 euro still cheap dean, better than 600 odd for a new one.
Man you need some new gloves 😂
I'm setting up a go fund me page for him.
Hi, Dean. I have to say. I enjoy watching your videos the most out of all 80 subscriptions. I have on being a viewer even though I'm in the states and I tend to have Dewalt and Makita tools.
I've always wondered about Milwaukee tools. Thank God for all of your insight and info I have turned wrenches on heavy equipment. And over the road trucks for 25 years. There's the main reason why I've only gone with the wall strictly because of my Mac tool dealer Mac tool. Power tools are Dewalt. Tools just re branded and colored differently. I know most people in the States care about the warranty I believe that they think if it has a long warranty and it must be a quality tool.
Which is where they get you, which I can't seem to understand because I wouldn't want to be bothered with having my tool down. Being a meckanek, my tools make me money. So the longer they're down, the harder. It is for me to do the job.
So When I've seen, most of the guys buying Milwaukee.Gay and you have shown me with the crappy Internals that they can technically go to a store that we have here Most people in the states care about warranty which I can't seem to understand because I wouldn't want to be bothered with having my tool down. Being a meckanek, my tools make me money. So the longer they're down, the harder. It is for me to do the job.
So When I've seen, most of the guys buying Milwaukee. Gay and you have shown me with the crap Internals that they can technically go to a store that we have here in The states that is called Harbor freight. They sell Hercules Bower. Tools that are all built in China, with the same internals. At a third of the just thought these.
Facts here. Would be interesting to you to see how kind of it is over here if you're a DYI. I don't see spending the money on the expensive stuff when some of the cheap stuff can actually last you. For what you do, if you are professional, you need to buy professional stuff, because it's servicablitiy and from what I have noticed, that is not Milwaukee, and I'm questioning Dewalt at this point. Again, Dean, sorry for the long comment. I just want to also keep doing what you're doing, You're doing an amazing job.
Spell check this edit monster
sorry but same same, getting stale
the channel is all about tools and tool repairs. but i get it can become repetitive. what other content would you like to see
@@deandohertygreaser Overview and review of the new 40v Makita stuff! Take one apart and show us how they look for repairs sake in the future - have you had any 40v Makita work yet? I think they have been for sale in the UK and Ireland for 2+ years now.
Expensive stuff in the line but if you want corded power in the likes of Grinders, SDS and Circ saws XGT will be a winner
@@shifty277 That one is fairly easy, not a whole lot of difference with the 18V line aside from the fact there is even more elctronics involved (40V batteries use a multiway communication with the machine). And the downfall of using more electronics is repairs even get more expensive, especially the controlers/fields of those machines. Basically the standard 40V (and 18V) tools are not worth fixing when it comes to electronic issues after the 3 year warrenty. And even on the more expensive ones (e.g. mitre saw 2x 40V) replacing electronics will cost you a large chunk of money. Some of the controlers will go down in price eventually (after a couple of years of production) like they did on the 18V series. But a regular 40V jigsaw or just a simple 40V scew/drill machine are just as bad or even worse when it comes to repairs as the 18V ones.
@@ElMariachi1337 thank you for the detailed reply.
Totally agree on the controller pricing as Dean yas shown these are quite pricey on machine in the 100-200 euro/pound bracket.
Im hoping Dean will have one in for repair some time soon or perhaps it may be too soon as in warranty (3 year registered customers) may be sending tools to the official service centre
need a variety of tools seems like they are all a much of a muchness
Consultant surgeon Dean, Makita on the ER operating table survived and makes a great recovery ❤️🩹 👍🏴
