Fill air into Metabo HPT cordless nailer 

I bought this nail gun as we were planning to renew all the fencing in our back garden. As this involved 19 double slatted fence panels, 10 of which needed to be cut down in size, we knew there would be a need for a great ru-vid.comUgkxHQsUrwNr5GQrnx9V4xDdUr56qxwuiBHt deal of re-stapling the wooden slats to the wooden framework. Each alteration required the re-stapling of 62 wooden slats with double staples. Prior to starting the work we ordered sufficient additional staples as per the instructions with the gun.The gun performed fantastically throughout the entire project with no jams of misfires. The adjustable power was excellent allowing the staples to be fired into the 8mm slats to the correct depth. For the price paid this was a bargain and it proved itself to be so reliable and versatile making an arduous task much quicker and professional. I cannot recommend this product highly enough and it will be used on many other projects in the future.

Please keep throwing down these incredible videos my friend!!!!! They are perfectly presented and conducive to actually hearing and retaining the info people are here for. No loud over the top music, you dont ramble on about nonsense, and your camera is nice and still so i could actually see what you were doing perfectly..........Thanks man, good job!!!

Great video. Now I feel confident in buying a cordless nailer. I enjoy servicing my tools at home because it saves time and money.

Just an amazingly comprehensive easy to follow guide to refilling your nail gun. I love hitachi mhpt tools but the nailers are the gold standard of cordless although the new Aeg or Ridgid depends where you live but the Ridgid framer is a beast and maybe my favorite nailer out

Awesome video! I have the NT1865DM(S) finish nailer... ordered the regulator on Amazon and followed these excellently presented instructions. The gun is working great again, and now I'll be able to recharge it quickly whenever needed. Glad you made this video, because I was about to chuck the Metabo and go back to a Paslode.

Great information, I didn't even know that this had to be done eventually. Just hadn't thought about it. I have the Hikoki/Hitachi branded framing nailer, and the finish nailer (16 ga) on its way in the mail. The framing nailer is basically brand new and has plenty of power, but now I know what to do when it eventually gets worn enough to warrant this fix. Thank you!

I cannot thank you enough for this I had 5 dead nailers seriously appreciate you taking the time to make this

Thank you so much this is the only explanation for what’s going on with my gun! Now to find a video for my dewalt laser ...

No bs, clear and concise. Thank you.

I can now see why many are selling their old metabo or Hitachi nailers. If they only seen this video they'd still be using them. I bought the regulator.. Best buy ever. Thanks for the video

Thx. Been using for yrs and always send in for this, now, don’t need to. Cheers✌🏻

This is so helpful as a framing contractor we have a few of these they only last us a year or less until they die we send them back under warranty but when the warranty runs out it cost more to fix them then buying new. I understand companies have to make money but feel like we've been taken advantage of.

thanks for the great informational video. just did this to my 30⁰ framing nailer and my 18g Brad nailer. works great now

Great Info...Thank you sir!

With the chamber filled with air, how long will it last before re-charging with air again? I am in the process of purchasing one of these, but never have used one.

With the regulator I removed the hose and put a 10 mm long socket over the screw and hooked up the hose again. Was much easier to screw it on. Saw this on another video.

Cheers mate 💪

You are a rock star my friend, excellent concise instructions. Go corporate, show them a thing or two on how to treat loyal customers! I don't expect perfection but demand solutions! I have the new 18 guage NT1850DF. Love it, but have hard use already, little low on air. Do you know what regulator for this newer generation gun? Looks like the entire case needs to come off for the fill on this one. Thanks so much!

Your a god🙏🏽🙏🏽🙏🏽thanks for the info

Can i use any air compressor or is it crucial to have a air drying system on my compressor ? And what regulator do i need for the new 36volt NR3690DC ?

HI, sir. where can we purchase the regulator? I haven't find it online.

Hi, would you know which fitting goes on to the regulator valve airline end? I'm using PCL XF, and it fits but leaks massively. Also wondered if it's safe to change the fitting on the regulator. Cheers

Hello, i need some advise. Recently i bought a secondhand hitachi NR1890DC but now, the nails aren't driven at all. In my humble opinion, the piston tip seems to be worn. But i can be wrong (i never saw a new hikoki tip) Need the piston driver be replaced or not? Thanks.

Got a brand new Hikoki here in NZ. 16Ga totally lacked power. Sent it back 3 times, apparently it was user error! Got me the regulator and all fixed. Give them their due they apologized for not getting it right, but didn't pay for the regulator. Happy ending and I now have a new sideline re-gassing the Hikoki's in NZ. :) many thanks.

Does anyone know the size of fitting for the compressor hose to the hikoki regulator? I emptied my gun of air to discover my hose fitting is smaller that the regulators fitting!

What regulator/part number do I use for the (NR3690DC) 36 volt framing nailer? Will the one in this video work or do the 36V need a different psi? Like all of your videos... this is a awesome!

Any chance you could sent the link for buying the right regulator for the 15g nailer?

So it’s regular compressed air from compressor or has a special gas ? I heard this happens to other brands the Milwaukee but no one has attempted to refill and it has to be send to their repair dept hmm idk if they charge extra for that and hopefully it’s covered by warranty any idea ?

Great video! I bought a Ridgid cordless nailer (R09895B) and it has run low on air so I am trying to figure out how to refill it. There is an inflation port that looks like a typical tire inflation port and the manual says to pressurize for 30 second to a max of 125psi. Problem is, nothing happens when I try to pressurize it. I am guessing that it too will need to be put into maintenance or service mode. Any experience with this or suggestions? The hammer is useless unless I can refill, and nobody (including Ridgid!) seems to know how.

Do i need to use the same brand nails ?because i try dewal portercable and does't work the nail stay half way out

will this work on 15ga and 18ga nailers? where did you buy this adapter?

What regulater is need for the finish nailer? Like th 15g 18g and 23g?

Any advice if after doing the procedure you show, the pin does not reset?

My m18 Milwaukee nailers are supposedly filled with nitrogen and supposed to last for the life of the tool. No idea if they will, but I wonder if they are serviceable like these

Is this the only metabohpt battery nailer u need to do this for

Interesting. Is this something that you have to do on a regular basis? What is the tell tale sign that this maintenance has to be performed? Thanks for a great video.

Great video. I'm curious what symptoms would arise to show this issue. I have a nailer that's leaving the nail completely proud and sputtering. How much do you think it would cost to bring it to a repair shop? Thanks in advance.

I have the framing nailer "NR3690DR" and the newest 18 gauge brad nailer "NT1850DF". What are the regulators for those guns specifically? I have tried to find them online but cant find any reference to the guns I have. Thank You

Will this method work on the cordless metabo 16 gauge finish nailer?. Gun is new and just clicks hardly shooting nail

In the Milwaukee, you have to take it apart and use a special adapter and nitrogen gas.

can I use this duplex model as a 21 degree framing nailer？？？

Whats the part number for the smaller rafter hook

i have a nr1890dc that misfires alot had it sent away to get fixed ,but came back in the same condition ,any thoughts?

Would it be a good idea to put a couple drops of air tool oil in the regulator or remove the schrader valve and put a couple drops into the gun? Or is oil in these guns a bad idea

I just stumbled over your video, just bought a duplex nailer, how often do I need to do this or how would I know that this needs to be done? Thanks

The adaption valve set. What is the function of the component attached to the hose? Pressure limiter?

Darn, i just ordered the valve kit 371208 and it will work with my framer but i wanted to recharge my 18g nailer NT1850de. I seen that you mentioned that this kit will work unoficially with the 18g, am i able to just set my compressor to 51psi and charge it like that?

Where do I find that air regulator you’re using?

Hey bud, where do I get this attachment to fill up the Metabo nailer?

Where can I find this little hose with the adapter?

Would the same adapter and psi apply for the other metabo nailers ?

Looks like the same connection as my air suspension pump for my mountain bike. I might give it a shot since no one seems to have the part in stock.

How often does the 3 1/2 nailer need to be recharged and what happens when not recharged

Hi great video what psi do I need for nt 1865dm 2nd fix Nailer I've topped mine a few times but never get the same performance as I did...any feed back would be great thanks...

Bought a metabo 1865dms from the states and had it shipped to Europe. Nails don't sink , would the flight over have affected the compressed air in the gun?

Hi, Do you know if that regulator will fit milwaukee nailers?

Nice Instructions. But why does this need to be done? Came across this video looking for reviews of this model, for prepurchase information. Why and When does this need to be done? Thank You!

What type of regulator you need for a milwakee 18v cordless framing gun?

Phenomenal tutorial! My 16 gauge and 18 gauge Hitachi 18 volt are not setting the nail properly. Can I use the same method with the same regulator to fix them?

I have one that don’t shoot the nail all the way in could this be why

I can’t seem to find the part number for the Plug

Is it recommended to put other gasses in it than compressed air? To prevent it from getting hot.

As I read the comments, I'm reminded how lazy people are...smh. I can't believe how many times you've answered the same question when all one has to do is scroll. So much wasted time when you could be creating contemporary just something productive. Hats off to you sir.

I couldn't find this question and the answer.. Will the charger of this tool be suitable in Europe? I understand that the plug will need an adapter, but the current will not fit this.

My gun has started to make a different noise than normal and is not firing nails. Is this likely the issue???

Anyone have a link for the regulator for the 18v framing gun? I want to use it for my 15g gun to get more power. Im in Australia so I cant browse the amazon usa site.

How often do these need refilling, I've just changed from Paslode to HiKoki(Metabo HPT) for a maintenance free solution have I made a mistake!.

My nailer is only driving 3” nails about an inch in. Could a bad battery be causing it to not have enough force? It’s been stored for over a year. When I charge the batter the indicator light just flashed red. No matter how long it’s charging. And when I place battery back in the nailer. And I press the battery indicator it lights up red.

Thank you thank you thank you 🙏 yeah!!!!!!! Now I know how to fix my nailer She coming out of retirement. Just wondering can it be fill with nitrogen???? Just wondering that’s all

My Hitachi 15 g finish nailer made a crunchy sound about six months after purchasing tried to reset it just flashes the lights, any ideas.

Thanks that's a good video very informative. I bought the adapter from Amazon but one of the fittings of course the smallest is made out of Pot metal and snapped off. I was trying to be careful and just do it hand tight and then a slight snug and when I was all done after charging it going to take it off it snapped off. For the price it should be made of much better metal at least brass

I have a question. Is it also used for a rigid charging nailer?

Every time I try to remove the regulator all the air leaks out no matter how fast I try to take it out. Any idea what I might be doing wrong? I have the 16ga NT1865dm

Great video do you know what psi the 16ga finnish nailer takes? NT 1865DM is the model number i think, thanks.

where did you buy the regulator? Please 🙏

i was wondering why that plastic cover fell off when i was removing all the screws. my gun was working fine; then after 2 days off and a cold spell in the weather, it stopped working. It will stick the tip of the nail into the wood and then it starts to stutter or chatter. Seems like I should try this out. Thanks.

two yellow lights flashing reset as per video. pull trigger tool goes back to flashing lights . help!!!!

My 15 gauge hitachi hastbe firing pin stuck open and wont go back ? What do i do?

Would be great video if you were able to see where your fingers were .. i saw half of the gun and the items at the too of the screen ... hope i can figure out the proper buttons to push

@allenr1967 I just inherited a NR90AE Framing nailer, NT1865DMAS 15g and NT1850DE 18g nailer. The 18g wouldn't set 2" nail in pine today on my first real use. I read different regulators and different PSI settings in the comments. Do you have this info consolidated somewhere? Will the adapter listed above do all 3 of my nailers? Does the 23g need recharging too? I just bought that one too. Any help is appreciated.

How often this kind of maintenance has to be done?

I have searched every corner of the US for one of these. Are you able to say where we can get one of the regulators from?

Do you have to discharge all the air before re filling it? Can you not just top up the air chamber?

hello, tell me how much pressure needs to be pumped into the nailer?

If you haven’t got an air compressor could you use an air compressor for a car tyre with the regulator attached to it?

Can you just use an in line regulator, instead of buying separate one from Amazon or Metabo?

Will that work witch hitachi nt1850dbsl?

Please link the part 371278 can't finding anywhere !

Heck ya! I just reset my 18gauge nailer that was flashing orange. Saw how to do that on another channel. But then saw this video so subscribed! Good to know how to do this when needed! I think these guns are filled with nitrogen? Or another gas? Am I right? Anyway, I'm sure plain ol' air is fine too.

I got the regulator and went to refill my gun, I do the whole process and every time I remove the regulator to put the plug back in all the air leaks out, is there a fix to this?

Hi, the striker is stuck in the out position on my hitachi nailer. It has air in it, but it wont retract. Does anybody have any idea of whats wrong?

where can i buy that regulator i need it can someone help me by sending me a link about that product thanks

Great video, concise, no bs. Just got a regulator, after a month on back order. Is the psi the same for the 18ga and 16ga too?

What seals need to be replaced when it starts loosing pressure ?

will this valve set work with Milwaukee cordless framing nailer

Great video. Do you have a video on how to change the seals also? Thanks 👍

what brand of nails do you use with this ? :) thank you!!!

Hi mate , my regulator won’t hold the pressure in , as soon as I take the air hose off it drops all air from gun . Any ideas ?

Hey great video! How much psi would you need to add to the NT1850DE?

Good video ! The reg kit seems hard to find.
