Repairing a bunch of Hikoki and Metabo HPT NR1890DC nails guns. Problem is, they won't fire nails 

I love how Dean goes everytime on a rant when Milwaukee tool is mentioned.

I was waiting for this one. I'm a Bosch user, but Hikoki nail guns are some of the best in my opinion. I own the 1890 and the 16Ga. Never had any problems with them. Sometime ago I bought the refill service tool so I don't have send it to a repair center. I really enjoy watching your videos, they're very educational and since I do maintenance and repairs on my tools it's always a great opportunity to learn! Thanks.

Hikoki guns are unreal. Outperform the paslodes easily and only slightly behind the Milwaukee in power but doesn’t weigh anywhere near as much as that hefty unit.

Your tool knowledge is just amazing. Love to watch your vids!

Worth noting with these hikoki guns… with a certain combination of button presses on the on button and mode selector buttons… they go into ‘service mode’ and won’t fire but flash…. The problem is when the gun doesn’t fire the user presses all the buttons and tries everything and ends up in this mode by accident and it’s another combo of presses to get it out of it….. if you know you know. if your Youl think it’s knackered. hope this helps someone..

Such great wisdom shared from someone who has spent their life around these tools. Invaluable. All of the tips, advice, anecdotes are super useful and interesting

was walking around my local Bunnings and passed by the Paslode nail gun stand and had to resist pulling them apart i feel i could do it after all your vids. over a $1000 each over here in AUS ....

Thanks Dean. I am unlikely to use any of the nail guns but I now understand how they function. The Hikoki of the three main makes looks to have the simplest operation.

Def love the show and tells and the explanations!

Who knew those guns were so complicated. Nice one Dean.

Best video for repair. Thank you. You are the best 😊

Good deal! Learning lots from your videos. Can't thank you enough for the education.

Great video. Thank you for the explanation and recommendations. I learn a lot. Thanks.

Great to see your subs going up fast. Before you know it you will have that 100k

Nice job. I’ve just picked up a framing nailer and 15 gauge nailer. Glad you like them! Like the cordless feature. 😁

wow I just commented on your last video if you had any hitachi cordless nailer service video's and here we are. actually metabo bought out hitachi, in the US/CAN hpt stands for hitachi power tools, great video

Thank you, now I know how to service and how they work.

I can’t tell if you’re trolling us state folk by calling it metabo HTP. It’s HPT!!! Haha. It stands for: Metabo Hitachi Power Tools

Thanks for the excellent vids Dean. Inspired by this one I had a go at fixing my sons NR1890DC. It powered up ok with both blue and green LEDs on but absolutely nothing happened when you pulled the trigger. Took it apart to have a nosey and test the trigger switch. No problems found. As I was putting it back together noticed a small white plastic rivet below the depth adjuster had fallen out of place. Turns out its magnetic and I'm guessing its for the hall effect sensor it that position. temporarily siliconed back in position pending obtaining a replacement and hey presto! all working. thanks again. Mike

Top video fella

Great vid! 👍

This makes me excited for the Makita Framing Nailer that has many patents out! Seems like they are going with an air cylinder design thats even more serviceable

Sorry Dean i meant makita battery framer The makita second fix guns are good Even ryobi has a battery framer Makita have lots of registered patents but behind the market on framer Love your channel Robert bribane australia

Dean, that valve looks exactly like a Shraeder valve for bike tubes. Easy to get online.

I absolutely love your videos mate. I would love to see you do a troubleshooting video. For each type of machine. Like what to look for when certain things aren't working right. E.g. Nail gun not firing. Look for this this and this. But anyway thank you for another great video I appreciate it 👍🙂

Thank you Sir

What camera do you use? Those close-up shots are really good. 👍 You Tube auto subtitles really has fun with your accent! 🤣

Lovely little video! Watched when on my break on site. Just out of interest have you had any experience with the makita 40v stuff yet? Any in for repair or have you have a peek inside if your tool stores stocks the line. Thumbs up. Watching from London.

I’m glad your subs are going up, you really deserve every single one of them! Entertaining and educational content! If your reading this comment give this boy a sub and a like 👍🏻

Let me start of in saying your channel is very informative, thank you so much for taking the time to post these. I have a question and I know this isnt the best forum to ask but i need a honest answer on some things. I am in a position of management at a shipping depot, we load items onto truck trailers. These items roll so to secure them in the trailer we use Metabo HPT nailers (nr 3675dd) to secure wedges around the items securing the wedges to the floor of the trailer. We have about 12 nailers on hand and they are constantly breaking. After a couple weeks of use the lights will blink orange and it will no longer fire. We use Metabo brand nails, we try to keep the guns clean, but no matter what the guns continue to break. I am starting to now question whether maybe the flooring of the trailers could be too hard. I really cant think of any other reason to have the guns continue to break. When we send them in for repairs to metabo they say that the part # 15 has teeth knocked off of it and it appears we are either firing nails onto other nails or firing with jams, both of which I cant say for certain doesnt happen but i can say everyone has been warned against such activities and I havent observed these actions. If you see this do you happen to have any ideas? Either way great channel! Thank you!

I'm assuming oiling the slide for the magazine is a bad idea due to being around wood and probably dust. That's the first "fix" that popped into my head after you cleaned it up. I work on heavy machinery, so oil/grease is always on my mind at work. 😂

Really good video, i was recommended your chanel by a guy of facebook , i was looking to see who repairs hikoki under warranty in ireland, not much good having a warranty if there's no one to repair them,

Great knowledge love your fault finding technique I was wondering about buying a nail gun but have no idea which one I’m retired now so it’s not going to be used on a daily basis so any suggestions would be appreciated because you certainly know your stuff not fussed if it’s electric cordless gas just what you would recommend I like the way your honest with people and know what your talking about very impressive look forward to your thoughts on my dilemma

That same cars tire valve has been used from nail gun up to scuba diving balance vest 😄

Thanks!

Like it when he say Maakita in his irish accent

I really do like your channel. I wonder if you could find the time to answer a question i have regarding a electric pressure washer. I can use it, but as soon as relieve the trigger the motor keeps turning on and off every few seconds. It doesn't stay turned off as it use to. I suspect some sort of leakage, so it cant keep the pressure up. Have any idea? Its a Nilfisk ALTO c120.2 (swedeish market, dont know if you have it in Ireland) Best regards, Gunnar from Sweden.

Wow!!! It looks like a cheap ordinary car/bike tyre valve! I think it worth to test tyre valve with these nailers.

Great video, just wondering when you said the Metabo was from overseas, maybe it was de pressurised for import? Good work btw

The preload pressure is actually not that high. The service manual indicates 5.1 bar +/- 0.3

Hey Dean, if you were going to buy a 16 gauge and 18 gauge cordless nailer, what would you get? I’m sick of setting up a compressor and running airlines just to do smaller jobs. I’m in the USA but can probably track anything down.

I guess you nailed it then 😂😂😂😂

So the story I heard was that when Hitachi sold off Koki power tools(Koki holdings), and Koki changed their power tool line name to Hikoki, Lowe's had a big problem with this and didn't want to sell the tools under that name. Lowe's is Hikoki's only national distributor in North America, and somehow they came up with a compromise of "Metabo hpt." Lowe's used to sell German Metabo power tools in their stores, and still do on their website, so maybe they figured their customers would be more familiar with that name.

Hi Dean, quick question here after watching the video of changing the blown fuse on this gun. After the fuse is replaced, I realised the piston pin was stuck halfway and regardless I reset it, the gun just flashed two yellow lights, and pin still in halfway. Shall I purge the gas to pull the pin out and regas or if there is any other way to reset the piston? Many thanks and appreciate your knowledgable vidoes~

What PSI should be charged into the air cylinder when it comes time to recharge it, do you know? Thanks.

Just needs a regas then they just keep shittin and shittin and shittin. Allll day long maybe shit a thousand nails. Haha I watch your videos all the time because your so smart and a great teacher but my American brain just cannot unhear you saying shit a billion times. Please don't change

so what is the pressure needed for the re-gas. from your vevor compressor psi/bar

Would it be possible to MIG weld some more meat on the last tooth on the pin? Build it up and file it down to correct shape?

Does anyone know what PSI these get filled back up with air to?

you can get a long reach valve tool, i think mine is toledo

Sorry Mate, I think your mostly right with your opinion about the service kit. But the seals for the piston should definitly be includet. Part # 11-14 are includet, If I read the drawing right. Cheers

The difference between the Metabo and Hikoki is that the Matabo is made using the imperial measurement system for size and air pressure and the Hikoki is all metric. It takes someone with a lot of skill to add the name on the different tools and they come off the same production line. From what I've heard those guy's can tell which is which just by picking the tool up, even with their eyes closed!!! 😋😂

Piston assembly is 211 pound and pinwheel is 112 pound ya looks good dean

I'll have to look up the weight of that hikoki gun. The ryobi I have is too heavy!

My Hikoki has randomly started firing 2 nails at a time! Any suggestions?

that valve I'm 90% sure is a car tyre valve core that maybe somthing to test if its the same

Hi just an observation the valve you replaced is a tyre valve the ones in bicycle tire would a modified valve tool not work better.

What part of the country are you in I can't find out why my gun not working . Green and blue light on but nothing happening

Koo videos need an metabo hpt 18ga brad nailer repair.

Is it possible to refill it without the gas regulator thing?

Hi Dean, great stuff! How do i go about getting some tools to you for repair? Thanks

WAs that an innnertube valve from a tyre???

Were did u get the filling adapter mate and what psi do they fill to

On the last I was screaming at the screen it's out if air....just regas it and check for the leak but even my bet was either the piston seals or more likely valve. Surely a leak check first would have been the priority?

Those valve cores are in all cycle puncture repair kits and can also be bought at any car spares shop. I certainly wouldn't be ordering them from the tool manufacturer at 1Ox the counter price.

What are your thoughts on metabo tools dean? I want to trade my Milwaukee stuff in and get metabo

The regassing be done with something like a 300bar hand pump the same as they use for air rifles. I have two of those pumps from Amazon at £36 each and they work well..IF you have the strength to get it to 300 bar. The max pressure is only about 120psi/8.27bar so even a cycle trackside foot pump can manage that. I suppose the tool uses its own proprietary fitting though just to make life awkward.

I love the channel, just was scratching my head on the last repair. You do know that valve is just a tire valve right??? You don't need knipex needle nose for that. Every shop everywhere has a tool which is under $5. And the part is under a $1. Keep up the good work, sorry no disrespect, that just had me saying. Why.

How many PSI / BAR do you charge the gun up to?

Love your work Dean, but, Makita framing nailer, where the bloody hell are you. Robert brisbane Australia

Metabo HPT (Hikoki/Hitachi Power Tools)

😊😊😊😊😊😊

I would love to have your job or work with you I will learn a lot

So nobody is going to comment on what it sounds like when he says "shoot" lol?

Not the kind of dirty magazine i was thinking if.

Milwaukee no

they are very heavy

Hitachi bought Metabo then sell Koki division to Chinese without rights to Hitachi name.So they decided to rename tools Hikoki (Hitachi +Koki) and for America Metabo HPT (Hitachi power tools-HPT).

Koki is insanely cheap when it says Metabo HPT on it. Over €200 for a drive pin? That’s basically the price of the tool + charger and battery.

I will no longer buy a product that can't be repaired, the problem is finding them.

Speaking of cons, DIY tool con: Ozito (Einhell in EU) want AUD $20 for brushes for their AUD $50 random orbital. 7 years old, guess I'll buy a new one.

Maybe someone purposely left the air out of the Metabo, you know like a disgruntled employee.

I think the branding thing is to do with the perception that the USA doesn't like things Japanese. I remember when Japanese Diesel Kiki decided to rename to Zexel in order to make progress in the US markets.

that first hikoki was ABOLUTELY still shooting nails. what in the world was that one about. how on earth was the wood getting torn up like that where it wasnt before if the nail wasnt getting shot

Way to many jump cuts,every time you have a problem you cut it out instead of showing how you solved it...This is not helpful at all for someone trying to do this repair..

I wish I had your knowledge of these power tools. Amazing. I have a dhs680 makita circular saw it runs and the switches off. What could be the cause my good Sir.
