@@sarimsalman2698 Its just too expensive to enter other power tool platforms. I find Makita power tools more ergonomic as well. Unlike Milwaukee tools.
@@sarimsalman2698 Exaaaaaactly! The majority of my tools are Makita but I do own several from milwaukee, festool, ryobi, dewalt and others. Hell, I'd even go for some of those VERY cheap made tools from Harbor Freights if it gets the job done good enough.
always make sure the driver piston is fully extended(meaning like where it would be when shooting a nail and not going back in) before refilling metabo hpt has a maintenance mode i believe milwaukee does too or you can just make sure you install it like that when putting it back together but if you dont you will be charging a smaller portion to the "correct"psi and then when u shoot a nail the chamber opens up and your pressure is not really where you thought also if your gun is fully charged and you take it apart be very careful moving anything around because if that motor slips it will go off and you can get seriously hurt
I was told that pressing the power button 5 times and then depress the safety only and fire it so the pin fully extends. I tried it on my 18 g and it didn’t work lol.
Thanks for showing us how it’s done. Another reason to buy the Metabo HPT nail gun. Don’t get me wrong, I’m fully (over?)invested in MKE tools, but I still research many major tool purchases. As for proprietary battery platforms…I still buy a fair bit of corded / compressor-powered tools.
@@Doyle047 The Milwaukee gun is "supposed" to be charged with nitrogen. Just like when the dealership puts it in your tires and tells you you have to come to them to get your tires filled, I feel like it actually doesn't really matter if you just use normal air.
I have the Milwaukee 23 gauge pin nailer, 18 gauge, and 15 gauge angle nailer. I love the mobility and ease of use of all these, but the pinner just starting acting up, not setting the nails all the way leaving about a 1/32" sticking out. Even with the smallest nail sets they leave too large a hole. Might as well use the 18 gauge. So, thank you for sharing this excellent video with us and I will be recharging my pinner very soon. You may have just saved me hundreds of dollars!
I feel like you could use a 90* elbow and drill a hole into the side of the casing to add a shrader valve so you dont need to take it apart everytime. Also, the thing I've noticed with those shock pumps being a mountain biker, because they screw on and it's such high PSI you always lose a good bit of pressure when pulling it off. When I do my shocks I always aim higher then what I want and when I pull it off it's closer to the actual Pressure.
Milwaukee uses nitrogen in nail guns preventing DIY repairs , so they claim , so little these have compressed air/nitrogen inside dont think it matters . Hitachi/Hikoki/Meiabo HPT uses compressed air , with filler point easy access, you dont need to open whole tool.
As a timberframer, I top up my tank about every 18 months and I normally do 170 psi so it could sink 90mm ringshank into C24 timber. If you do too much pressure, it'll stall the motor, stop working
Thanks bro for your help ,I had 2 milwaukee 18 guage brad nailers and bought a third one but after this video I tried to fix them and it worked, you're a life saver, 👍
planned obsolescence can be reasonable if fixing the problem is engineered in. this however is engineered not only to fail, but to not be serviceable, that should be criminal
for lube use white lithium grease, get the metabo/hitachi you can get the proper refill tool and buy all the maintenance parts. you don't have to send it back to the factory. The metabo recharge tool doesn't fit (it has different threads)
Good video, great tip. One very small thing to note, I'm very sure its originally filled with Nitrogen. The molecules are larger, so leakage/seepage happens slower. Looks like regular air works, though, so, small detail
Yup the metabo hpt/Hitachi ones used to use nitrogen too but they stopped using it and just swapped for regular air with no problems, maybe a litttttle extra seepage but if the gun is serviceable it doesn't matter at all.
@ds29912 approx 78. When you buy Hydrogen Peroxide at Walgreens, it's only 3%, if you buy vinegar to cook with, it's only 5%, but 6% or stronger for cleaning. So, there's definitely a difference between 78% and 99%.
Seeing that it's an o-ring on the piston head, it would likely use silicone grease - or the same grease used on pneumatic nailer rebuild kits. Should also mention that the original fill is nitrogen. Nitrogen molecules are bigger so are less likely to leak or leak more slowly, so if you fill with regular air will have to refill sooner. An option is if you get a nitrogen cylinder refill kit or maybe a tire shop that does nitrogen refills - though I don't know if they can or would be willing to refill with that much pressure not knowing the integrity of the cylinder.
That's the same BS excuse used for filling tires, the difference in leakage is negligible. The real reason a nitrogen fill would have been used is because it will have been dry, and it's an inert gas. This both prevents corrosion and eliminates the possibility of dieseling the cylinder lubricant.
@@ferrumignis Paslode gas chamber gets affected for normal air and it has zero harmful effects for it so why would Milwaukee chamber get defect when it's even closed chamber doesn't affect so much humidity changes etc.
@@ferrumignis I don't fill my tires with nitrogen for that exact reason. A tire is not a sealed metal cylinder designed to constantly pressurize at high instantaneous psi. Feel free to refill your cylinder more frequently.
The Hitachi accessories isn't meant to be sold to the consumer just dealers and repair agents. Also the Milwaukee service portal recommends 125 PSI of nitrogen.
I think they use those screws so people don’t accidentally kill themselves. I’ve worked trades for awhile and I think half my peers could do this safely but the other half…
Torx is already pretty much standard for most power tools for mechanical reasons, that's the main part, but it could be partially for liability too. If they make it reasonably difficult for the average joe to open up they can claim you went out of your way to open it and should have known what you were doing, in the event that you hurt yourself.
That's why I like the Metabo/Hitatchi guns with the access port and that are user refillable (and you can also add more psi easily to make it as powerful as you want). Also interested to see if the lifetime warranty on the new Flex ones includes recharging.
the flex also has four screws on the back plate and you can get right to a fillport there similar to how metabo hpt works even has a sticker to tell you the psi makes it very easy
Also go -0.87psi (~-1bar) vacuum with a security pin holding the striker before filling. You want the striker to be all the way out before fillin/vacuum
Milwaukee really messed up with this tool, now imagine how many nailers will end up in the bin because it would not be worth sending them back for service. Planned obsolesce.
There is a youtube channel named Dean Doherty focusing on tool repairs, he regularly says that quality vise, Milwaukee is a DIY tool at best, since they break too fast and in order to fix them he needs cannot just replace one specific part, but usually an entire assembly of them. I see plenty of people being happy with the brand, but there probably is a disparity between comfort of use/performance and durability.
I just sent 2 nail guns in last week and got them back in less than a week, it was free and they pay for shipping as long as they are less than 5 yrs old, I had no receipts
@@ItllProbablyWorkyou could probably still have gotten it done for free if the serial number shows less than 5 years from date of manufacturing. If the serial comes back less than 5 years it's free. I believe they even warn you this will happen in the manual and tell you that you'll have to send it in to get recharged for free once in a while.
In Norway refilling a milwaukee nailer is about 250 bucks. Hikoki will do it for free. I do however have an adapter to fill it myself. The problem with milwaukee is that it uses nitrogen (?)
There's one important issue with using these valves, they don't have the pin to depress the stem inside the canister to get accurate reading of the current internal pressure. Some newer cordless pumps like M12 and M18 for example rely on that reading to stop pumping, basically you have to use "manual" pumping as in rely on compressor tank/regulator readings to pump to that value and hope it's correct. Hitachi attachment has that pin but might be slightly different in design though so if someone ever tries that on M18 please post your findings/experience.
Don't complain about security screws- anyone that is knowledgeable enough to work on tools, equipment, etc will have these bits as they're not exotic (and even come as part of larger bit kits these days). They're used to keep kids and people who have no idea what they're doing from messing around and damaging the tool (or themselves). They also provide legal protection. If all you own is a flat and phillips head screwdriver you're not doing this kind of stuff anyway and likely aren't very handy.
You could take apart the new one and check its pressure- just before educational purposes to once and for all tell the internet the OEM pressure Milwaukee sets it at
I’ve had my framer hitachi for 5 years now and never done the re-gas 🤷🏻♂️ though does get a full clean and pneumatic air tool oil every year ish. your compressor oil looked very thick though. stuff I use is quite thin, takes a few days for the nail gun after the service to not send nails 10-15mm deep into the timber.
I thought they filled it with nitrogen? Wonder if that makes any difference. I guess air is mostly nitrogen anyways, but I wouldn't want the oxygen playing havoc with anything. What with that oxidation business.
Yes they do use nitrogen to keep the cylinder from rusting. Putting just air in will make that tool useless in no time. I just bought this nailer and am going to take it to a tire shop and get them to put nitrogen in when it needs it
They added that feature on the Ryobi and Ridgid framing nailer where you can pressurize it. I guess they finally got tired of fixing it with the Milwaukee, so expect a gen 2.
@@ItllProbablyWork I kinda want to just sell my Milwaukee and stick with my Hikoki. I have everything which includes the long magazine, but Hikoki also released their long magazine just a month ago.
Just make sure when you pressurise the tank that the firing pin is all the way forward as if you've just fired a nail. If the pin is all the way back ready to fire & you fill the tank you're only filling the part behind the plunger & you won't have the required pressure. Also before working on these make sure to purge the air & make sure firing pin is all the way forward to make sure gun is safe to work on. Also 210 psi sounds way too high to me. The metabo/ hikoki Framing nailer only needs 72.5 psi with the special air regulator used to refill them
Milwaukee uses nitrogen not air so that may be one of the reasons they don’t want you filling the cylinder. I honestly don’t know if it makes a difference they say it does.
@@evictioncarpentry2628 are you trying to say that putting air in is the same as putting straight nitrogen in because it’s not bud. Air condensates easier than nitrogen. Which I’m assuming may be one of the reasons for the nitrogen
@@steffendetrick OK, here's some facts. Every nail gun on the market right now uses the same technology. They all license Sencos patent. There are easily half a dozen other guns on the market now and a few of those are user rechargeable with compressed air. Are all those other companies wrong? (Two of the them are the same parent company TTI as Milwaukee) I don't see anyone having an issue with them. There is no difference in this case of pure nitrogen or atmospheric compressed air.
@@evictioncarpentry2628 Im well aware that it’s a senco patent . what does that have to do with anything? Just because a company license a patent from another that doesn’t mean that the technology in all of those brands that licensed it are going to be the same. Each company is going to implement their own design type that technology. I clearly said I’m not sure why they use nitrogen but it does not condensate as easily as air does. Milwaukee probably has there reasons for using nitrogen. your rant accomplished nothing.🤦♂️ you’re not telling anybody anything new and you’re not addressing anything that I said. I guess that was supposed to be a flex.😂 like I said, there is definitely a difference between pure nitrogen and compressed or “ atmospheric air”. One condensates easier -air, which is also why you have to drain your compressor.
Bro i did excatly what you did with a mountain bike pump , mine goes up to 150 psi and it was enough . Now the fraimer is like brand new but i forget to put oil in the cylinder i don't know if its a worry or not for the sustainability
If you didn't clean the grease off the cylinder and bolt you're probably okay. Cleaning and relubricating is mainly important to keeping your seals better for longer
It would be cool if you drilled a hole in the side of the body and used an extension hose or something so that the refill valve is accessible without dismantling the nail gun.
That fitting didn’t work at all for me? There’s nothing in the adapter to engage pin in the Schrader valve deep in the recess. The Makita tool has that. I’m curious how you magically made the adapter work?
Hahaha 300 bucks I spent over 600 bucks with the extend mag for the damn thing the first day they came out with them an I loved the huge crest wrench u used that was epic lol
You think its crazy but if you loosen the allen wrench locking pin you can turn the cylinder refill nozzle up then drill a hole through case. NEVER HAVE TO OPEN IT TO RECHARGE IT AGAIN
The screw was by the threads for the cylinder housing and the schraeder valve was going down into handle. I turned it to face out the riggt side of gun. So i got a dewalt cordless tire inflator and it goes up to 160 psi to refill the cylinder
I had an issue like this. Bought the valve adapter and tried to add pressure, seemed like it took air but i cannot get it to fire a nail in more then half way of a 3" nail. Daum you Milwaukee!!
You might need to put in more pressure, as the video mentioned I ended up putting a lot more than I expected I would need to. You might also check your seals
@@stabila9706 You can adjust limit on compressor pressure switch temporary to increase the upper limit BUT it would also depend on compressor and I wouldn't go above 160PSI, some compressors are set up for 155PSI from the factory too.
I just got one apart, waiting on the special end to refill the tank. The tank itself says 102 PSI, just wondering if anyone else has fixed one and how much you put in. I saw another video where the guy put like 160-180
That BST Schrader valve doesn't work for the 30 degree Milwaukee nail framer. The Schrader port is too long and the BST Schrader valve is too short ..Has anyone tried the Hitachi reduction valve???Please let me know, Thanks in advance.
I was led to believe that Milwaukee pressurize their nail guns with "Nitrogen". Not just compressed air. I see it does work with air, but just be cautious with it.
So it uses nitrogen rather than normal air, so that'll be a little different. But the other issue is the way the valve system works it's pretty difficult to actually check the pressure already in the cylinder
@@ItllProbablyWork I dare to disagree. For best results, it has to be 100% Nitrogen. For many other reasons then just compressibility. Oxygen and other gases are far more reactive at high pressure and may even cause some oil and grease to self ignite. That, I guarantee, improves anyone's hair style for a while. O rings are also affected by oxygen. By the way, in another life, I worked with 400 PSI air systems. (Rock drills namely) And also, Nitrogen filled dampers. I know you do not fill with air something designed for 100% Nitrogen. It's gonna work up until it doesn't.
AEG/RIDGID is the Best. compressed air to 125 PSI. You dont have to take the gun apart to refill the air it already has a Allen Key nut to with an access panel and you hook up the air hose.. I though Milwaukee ran on Nitrogen
