Hatsan Blitz full-auto failure fix

[@Boba-Fett-GS1150Ez]

THANK YOU! My B25 is only a week old and unmodified. It was very unreliable but only if it was low on air (

[@Atomsplitter69]

My first problem was Fillon it up. The Ada later that came with was faulty. I got an rma from Hatsan but decided to order another Hatsan and the fill adapater that came with works perfect on both.

[@sxt9169]

One more trick: the hole you pointed at 14:51 is actually for the power adjustment setscrew. After de-cocking the hammer you can loosen the setscrew through that hole. Then remove the hammer spring center cap on the back side and now you can use a long allen key to adjust the power setting from the back of hammer without taking things apart. I think it's the gas pin that pushes the hammer back. Because the gas port only direct the air to the barrel and between gas port and hammer it is blocked and sealed by oring.

[@highervoltage5430]

I agree that it is the gas that pushes the hammer back. Not sure why they made it this way, though.

[@makerofmanythings8447]

Do you happen to know the factory settings on the hammer screw settings? Thanks for your time and help.

[@reedsilvesan2197]

I'm going to suggest RED LINE oil. It is by far the best oil money can buy, and the price reflects it. I just finished cleaning and oiling one of my air rifles with it, (i use it to clean the entire rifle, including the bore) and even after washing my hands with Dawn, there is still a fair amount left on them. It's not a thick oil, but it stays on a surface like nothing else. It's a polyol Ester based oil, and is the only type of oil that has no oil in it. It is truly a synthetic, the same base stock as air conditioning oil, and also jet engine oil. All other 'synthetic oils' are petroleum based, cheaper ones from oil, more expensive ones are actually formulated from natural gas. A very thin coat will give superior lubrication and will 'adhere ' seemingly forever. And thank you for a superb video, as my new .22 Blitz will arrive tomorrow, and the first thing I'm going to do is disassemble it as per your videos, lubricate it with RED LINE, and reassemble it properly tightening the fasteners.

[@robgee7788]

I find this gun to be a fantastic piece of mechanical engineering, however, Hatsan has dropped the ball on tuning and Quality Control before the gun is shipped to its new owner. I followed your videos and opened mine up to find it packed with grease. Like, bearing grease. I used solvent, Qtips and a rag to get rid of all the grease, cleaned the parts and put a few drops of oil. It is evident Hatsan doesn't care if these work properly or not, or, they are selling me someone else's problem as new. I suspect both to be true.

[@dxbrc]

thank you for a great video , one note instead of using oil on the thread why not use blue locktight ? the oil will make lose after few heat cycles , second i discovered some of the jamming is happening because the magazine cannot cycle well i think the spring is a bit weak . although i have the .22 but still jamms after inspecting the magazine its showing wear of the parts in between of rounds . currently working on to find a way to increase the spring tension a bit . great work

[@danielww9022]

I never lubed my 30 cal, but I did overfill it once. Then I noticed it started jamming in full auto. I don't know if the overfill is what caused the jamming, but I definitely need to take it apart & inspect everything. I've never had it apart.

[@DrSaminstine]

I agree about the harmony it’s too touchy and needs reworking. But if you get the tuning it’s a amazing air gun. I think there will be some great things to come in he future from this platform.

[@highervoltage5430]

It is an amazing gun. I really enjoy mine. I just wish they were a little more refined so the action wasn't so delicate.

[@TangerineNguyen]

Hello there I just bought the new hatsan blitz like your and the first fill doesn’t hold the air , all the air from PcP air compressor come back at the filler nozzle ,tried to many way but still can’t fill the tank for first time first shot , are there any way to fix before I return it ? Thanks you

[@terminadorairgunsandoutdoors]

Does your silencer have a large 14mm hole or the Normal 1/2-20unf style with 30 cal hole?

[@jactilm8687]

I am finding out pellets will also cause a jam i tried Exact jumbo monster 25 grain .22 cal jams because the skirt is a little bigger its hard for the bolt to push these in, they even hard to push in my bolt action m rod.Other pellets no jams.

[@stephangronau1082]

Hatsan Should pay you, great educational video

[@DrSaminstine]

I have one as well great video. Did you notice the small Hex screw at the base of the door for the clip. Look at the door and notice the step. Push the door down to fully open. They should line up. The screw is fairly long and can be used as a stop if adjusted right. Not sure if that’s what it’s for but it makes sense considering the step on the back of the door is a perfect match. No tape needed on mine. Just adjusted until the play was gone in the clip. Might need lock tight to maintain position through time.

[@highervoltage5430]

Thanks for the suggestion. I didn't know that at all!

[@locksmithsilva1163]

Did you replace the spring when you put the moderator?

[@meanunclebob1819]

After looking at the exploded diagram, watching a few videos on tuning/maintenance and reading about *why* pressure above recommended settings I can't help but remember the guy I knew years back that kept trying to 'soup up' his car one piece at at time.

[@FredZadeh]

Another cause of jam prob. In hatsan blitz. which i faced was breaking tip of sliding rod in small sliding piece which stops it from movement....it will totally make the gun useless....

[@FredZadeh]

Let us know if overfilling the tank will harm this gun or not....؟ thanks

[@MC-iw6nv]

Need help please. Our blitz seal is not unsealed, therefore the air escaped out when trying to fill with air compressor. Do you know anything about that?

[@emorycaudill]

Thanks for the videos, I just ordered the 30cal, now the waiting game. Ive always used pfe resins in my gun oils but may be to slick to offset the harmony.

[@highervoltage5430]

Teflon based lubricants should work well. I have never used them, though. The harmony is very delicate on this air gun. I wish Hatsan had a little more room for error in the system.

[@eze008]

Thank you! Good video I search every day for new Hatsan videos for fixing the Blitz. Been through all your steps several times with my gun and still learned good shit. I love the gun but I am very disappointed with Hatsan information support on it. This basic maintainance video is the exact kind of video Hatsan should have done for their cutomers of this 1000 dollar item. We should have access to replacement parts also. I can't even easily find some basic info of the gun like barrel twist rate. They should be paying you. Thanks again!

[@highervoltage5430]

Completely agree with you on parts and support. The lack of availability of parts is a big problem for me as well. It would be great if a company made some lighter aftermarket parts for this gun to make it more reliable. Additionally, I am a bit disappointed that the harmony is so delicate on this where many people are having issues.

[@TheLovedr79]

@@highervoltage5430 yes indeed, they need to have parts available. Your videos have been the best! In your other video where you use gear oil you have on a commonwealth games shirt. Where are you located? I'm in harrisonburg, va

[@highervoltage5430]

@@TheLovedr79 - I am in Amherst, Va. I used gear oil on the bolt mechanism and it worked well, but I found later that thicker oil can cause binding of the mechanism by way of the bolt and hammer contacting each other if the bolt doesn't move fast enough. Thus, I use motor oil now which provides less resistance since the balance is very delicate. I think Hatsan should consider redesigning this mechanism with a dedicated hammer catch which does not rely on the bolt to have moved since the movement of such bolt is a secondary action to the firing of the rifle. In effect, the ideal mechanism would catch the hammer and would be released by the action of the bolt coming all the way back. From there, the current stop will holt it just fine until the bolt fully closes.

[@drwily]

Your a life saver, mine was working fine but after looking inside it certainly needed a clean and i know understand the gun a lot better, thanks! Cheers from the Netherlands! (We have a HUGE airgun community here lol)

[@tmc5443]

Great video - Thanks for taking the time. I love your comment "It never gets old", great way to describe this rifle. I bought the 22 caliber and I now am having problems. The rifle had started firing on Auto even though set on Semi some times. Now I have the same symptoms as Eric e had 2 months ago -- pull trigger nothing, except I have noticed that when you cock the bolt back and then release it to seat the pellet, the hammer spring is also releasing 4/5 of the way, then when you pull the trigger, it has a very weak 1/5 travel forward. If I remove the piece shown at 11:45 ( its purpose appears to be to lock the bolt in place so the trigger can not release the air with the hammer back ) then the hammer will stay back and release with impact by using the trigger. I did not try shooting any pellets with that piece removed. The trigger mechanism on top shows a small amount of wear, and it is really flimsy. Any ideas? We have a blast with the rifle when it works. Everyone loves shooting it. I have started working on making a 3D printed loader to shorten the time to fill the clips - couldn't find anything already available.

[@highervoltage5430]

That is a binding mechanism. What is happening is the drag of the transfer piece is causing the mechanism to cycle slowly. Open up the left hand side and expose the gear mechanism. See how that is all worn out and has a lot of slop in it? Weld those 2 parts (linear gear and transition piece) so the transition piece cannot jam sideways. That will fix the issue. If you want, you can send the part to me and I will do a video on that modification since I already modified mine and it shoots so much smoother now.

Hi. My doesn't even shoot on full auto, only single shot works, do you know how to fix full auto

[@michaelcombs2045]

Where do you buy suppressor & adapter?

[@sxt9169]

Thanks for the video. I think the key is to keep the pull rod/bolt moving fast enough and everything will work fine. I smoothed out the machining marks on the gear and used purple compressor oil and it cycles pretty well now. I also reduce the hammer spring tension that seems fixed the full auto issue when the air pressure is below 150bar.

[@highervoltage5430]

Sounds like that is it! I actually welded the lower gear rack to the small rectangular part which is pressed by the long rod from the front. That kept it from twisting which made it work even better.

[@sxt9169]

@@highervoltage5430 I'll definitely do that too. My donnyfl suppressor is coming in soon. I'll see if it can cycle full auto without modifying any spring later. Mine is a .22

[@my2004ford]

Mine (without a suppressor) in .22 gets 5 and a half mags before it won’t cycle on full auto. I also have to make sure the magazine is pushed up and as deep as it will go or or may fail to cycle.

[@highervoltage5430]

Mine gets 6 full mags whether the suppressor is on or not. I figured out why the suppressor is a problem and it turns out there are two parts inside that wear out. Simply welding them together made mine shoot incredibly smooth.

[@my2004ford]

You going to share those parts that you welded in another video?

[@highervoltage5430]

@@my2004ford - Yes. I intend to do that mod to my .30 gun eventhough it has been problem free. The parts I welded are the lower gear rack and the small rectangular key. I shot mine so much the notch in the key had worn out and it was starting to jam up the gun by twisting sideways. They really should weld it at the factory. The only reason they are separate is to make the parts cheaper to manufacture.

[@my2004ford]

Good, looking forward to the video. I plan to shoot my .22 a lot, so I may be wearing it out too. Still trying to decide which to order, the .25 or the .30. I’m just north of you in Winchester, and I have family in waynesboro and Charlottesville.

[@highervoltage5430]

If you have the .22, get a different air gun for your next purchase. My .30 hardly gets fired due to the cost of pellets being 8X higher. I HIGHLY recommend the Huben K1. Another recommendation is the LCS Air Arms SK-19. Those are the most incredible airguns you will ever shoot. Feel free to stop by my place and give mine a try and you will see what I mean.

[@robertpsenica4818]

Did you have to make any mods when you added the DonnyFL? I was told that it wouldn’t cycle with a suppressor added?

[@highervoltage5430]

Nope. Nothing done to the Donny FL. Just had to weld the transition piece to the linear gear rack under the left hand side cover and all worked well. The transition piece twists sideways causing a lot of friction which slows down the action. By welding it, there is ample pressure even with the Donny FL suppressor.

[@raysmith6829]

You should always use silicone on any and all air guns

[@eze008]

Over the weekend my gun just stopped firing. The trigger pulls...the hammer smacks but no air blast. Have you ever had that happen?

[@highervoltage5430]

Broken transition socket most likely. Remove the 6 screws on the left side of the gun. Inside you will see a rod on top which connects to a rectangular socket and a linear gear below. That socket is under a lot of strain and can break. If you are handy with a welder, TIG weld the linear gear to that transition socket part. If you are not handy with a welder, send it to me and I will weld it for you and send it back. I need to make a video on this anyway. I welded mine up a few weeks ago and it has never fired better. If that isn't the problem, then it is in the air transition system. This could be as simple as a broken hammer spring. I have a few spares that I could send you if that is the case. I forget the Grainger part number, but I replaced mine at one point.

I'm going to test in the morning. If it is not the set screw I will proceed on opening the gun. By the way I noticed something different I think could be VERY cool if I am correct. The big round screw in back of the receiver that holds the hammer spring is different. It now has a flat head screw in the middle of that big round screw. I am hoping that this is a new design aimed to power the rifle easier without opening the cover and digging inside. I can share a pic if you like. Let me know. I will update you tomorrow.

[@Tom-xn7zc]

Get a very fine grit (400+) sandpaper or emery cloth and remove the burrs from the edges of the metal parts inside the trigger mechanism, especially the U shaped metal piece has some fitment issues. Clean everything very thoroughly and check for any binding before using a drop of light oil (e.g. Interflon FIN super or Ballistol). I also replaced one of the springs for a slightly weaker one to help with the heavy triggerpull. I think it was the one going straight up above the actual trigger but there are 6 springs inside the trigger mechanisme if I remember correctly so don't just replace the first one you see. The catch for the hammer should be pretty smooth already but check for burrs anyway. If that doesn't help it's best to disassemble the hammer including the bolt and every sliding part, clean everything, remove all of the burrs, polish the hammer faces and reassemble with a bit of lube.

It’s not a problem with the gun it’s the ammo people are using. The mags are not designed to cycle heavy ammo as fast as needed for the function of the bolt. The hatsan blitz is designed to shoot lighter grain pellets not heavy ones especially with the 25-30 cal models
