Fabhui Posted December 29, 2014 Report Share Posted December 29, 2014 2 days ago I filled (pumped) my Hatsan AT44-10 with air to 200 bar and put it away. I've taken it out to use today and all of the air has gone and the pressure is back down to 0. Do these have to be stored with the hammer cocked or something to prevent the air from leaking out? One other thing I've noticed is that I have the wood stock variant and it has sling swivels fitted to it, is this normal as all the ones I have seen online for sale don't seem to have them? I must point out that I've bought this brand new from a shop who as far as I'm led to believe is a reputable dealer. Quote Link to comment Share on other sites More sharing options...
turbo33 Posted December 29, 2014 Report Share Posted December 29, 2014 Nope, no secret, air should stay in. You have a faulty valve. Back to the shop unfortunately Quote Link to comment Share on other sites More sharing options...
bruno22rf Posted December 29, 2014 Report Share Posted December 29, 2014 If its leaking then its leaking-take it back and get a replacement-not a repair after you appear to have only owned it such a short time. Quote Link to comment Share on other sites More sharing options...
Fabhui Posted December 29, 2014 Author Report Share Posted December 29, 2014 It's going back tomorrow and once they verify there's a problem I can either have a refund or a replacement so I'm going to have a replacement. Quote Link to comment Share on other sites More sharing options...
fog horn Posted December 29, 2014 Report Share Posted December 29, 2014 Not really what you want from a brand new gun Fabhui buddy! I have heared about many with poor finishing issues thats what has kind of stopped me buying one.. Do they have the Walther Rotex in the shop? Might be worth a look before swapping like for like! Law of averages is the next hatsan will be ok but just a thought buddy.. Regards Foggy.. Quote Link to comment Share on other sites More sharing options...

They do have the Walther Rotex in stock but its £100 more expensive than the Hatsan and also don't you have to fill the air cylinder to 232 bar??...Not sure how much more difficult that extra 32 bar would be to pump with a stirrup pump.

subsonicnat Posted December 29, 2014 Report Share Posted December 29, 2014 (edited) Because in your Previous Thread you removed the Air Tank.. Possibly you have LOST the sealing ring where it contacts the action, There are spares in the plastic packet in which was the adapter for filling the gun. if it is not tight against the face, it will leak air.. There was no need to remove the air cylinder in the first place.. you did this I understand to charge the cylinder back up as it had air in it at all.. The Reason it Filled after you removed the air cylinder, was because the firing pin, (Air Release Pin) was not shutting the valve OFF, So you could not FILL it.. I know you are new to pcp`s but you should be careful as there is a lot of air in that cylinder... If You take it back and he see`s that you have lost the silicone seal, he will know you taken it apart.. Anyway best of luck, Funny it wasn`t charged up though when you picked it up. ? . Best of Luck. PS: When you screwed the barrel back into the action, was it cocked, if so you may have Bent the pin out of alingment with the valve, as said , Best of Luck.

I've just been to double check and the sealing ring is still on the air cylinder along with another o ring. The only reason I removed the air cylinder to try filling it was because I was having no luck with filling it with it on the rifle and I knew that it could be removed. The air cylinder was also tight up against the face, I didn't remove the barrel from the action. The only time I've cocked the rifle has been when I was firing it. Hopefully they will be able to sort things for me right at the shop. Quote Link to comment Share on other sites More sharing options...
onatangent Posted December 29, 2014 Report Share Posted December 29, 2014 Stick with it, there is always a percentage that fail be it a daystate, fx or a gamo.....or hatsan. Taken my aircylinder out plenty of times for servicing or tinkering and is fine still. Quote Link to comment Share on other sites More sharing options...

Heres Hoping everyone noticed that deliberate mistake... Just trying to pin down how the pin that pushes the pellet in has become out of line..

kriss Posted December 30, 2014 Report Share Posted December 30, 2014 I have 2 of these guns both with wood walnut stocks but no sling swivels fitted. the air on these guns is pumped in from the complete opposite end from where it comes out when fired. i once stripped one of these cylinders to replace seals and when i filled back up it leaked quite bad until i fired the gun about ten to twenty times then it sealed and never leaked again. as this is a new gun it might just want using i.e put quite a few shots through it and it will seal. in the 3 years ive had my 2 and my mate owns one to the only place they will leak from is the cylinder. unscrewing the cylinder wont void your warrenty. if cyclinder is completely empty draw cocking leaver back then fill then use if it still leaks then take back to shop. good luck.

evo Posted December 30, 2014 Report Share Posted December 30, 2014 my advice,, PUT THE EXTRA £100 WITH IT AND GET THE ROTEX good luck Evo Quote Link to comment Share on other sites More sharing options...
onatangent Posted December 30, 2014 Report Share Posted December 30, 2014 rubbish advice again then, why not put in even more and buy a hw100. Cock all wrong with the at44. Quote Link to comment Share on other sites More sharing options...
Fabhui Posted December 30, 2014 Author Report Share Posted December 30, 2014 Well it went back to the shop today. They inspected it and couldn't find anything obviously wrong with it. They filled the cylinder with air and couldn't hear any hissing. They've marked how much air is in the cylinder and are keeping it over night so they can verify there's a problem with it, then they're giving me a call tomorrow to let me know what's what.

kriss Posted December 30, 2014 Report Share Posted December 30, 2014 (edited) my advice,, PUT THE EXTRA £100 WITH IT AND GET THE ROTEX good luck Evo funny you should say that as I have a 1 month old rotex in 177 with spare mag and of course as new as used it once. fantastic gun but seen another gun I want.

evo Posted December 30, 2014 Report Share Posted December 30, 2014 rubbish advice again then, why not put in even more and buy a hw100. Cock all wrong with the at44. I am not slating the AT44, I just think that for an extra £100 it a better buy to get the Rotex R8, having used both the Rotex is better built and a far nicer piece of wood and the Rotex I used was certainly more accurate out to 40yrds than the AT44, but they where 2 guns I tried and as you know it might not be the same for all, I certainly wouldn't call it " rubbish advice " but it is just "my opinion " all the best Evo my advice,, PUT THE EXTRA £100 WITH IT AND GET THE ROTEX good luck Evo funny you should say that as I have 1 now im selling and only 1 month old 177 and a spare mag aswell. reason for sale ive seen something else I want let me know by pm about your rotex in .177, I might have a buyer for it Quote Link to comment Share on other sites More sharing options...
onatangent Posted December 30, 2014 Report Share Posted December 30, 2014 More accurate, interesting thought. Not had any issues with mine at those distances. I had a play with the rotex and couldn't see why I would spend more on a tool that did no more. Horses for courses as with everything.

fog horn Posted December 30, 2014 Report Share Posted December 30, 2014 I agree with you evo, I said the same thing further up in this thread.. really do think the rotex is worth looking at and I believe when the chap was looking into buying the Hatsan AT44 I mentioned the rotex in another thread! Yes its £100 more but its a better build and sure you won't regret it buddy.. like I say worth a thought and look to see how it feels to hold before you commit back to the Hatsan! keep us all posted to what you decide mate. All the best Foggy.. Quote Link to comment Share on other sites More sharing options...
secretagentmole Posted December 31, 2014 Report Share Posted December 31, 2014 The Rotex can have power problems! Oh yes. Like underpowered! Quote Link to comment Share on other sites More sharing options...
Fabhui Posted December 31, 2014 Author Report Share Posted December 31, 2014 When I first went to buy the Hatsan AT44-10 I also had a look at the Walther Rotex whilst I was there but for me personally it didn't feel as comfortable to handle as the Hatsan. Anyway, yesterday when I took it back to the shop they filled the air cylinder up but a clear sticker over the gauge and marked it in pen as to where the pressure was at so if air was leaking out it would be clearly obvious. Well I've just been to collect it and it hasn't leaked one bit!! I'm not sure if for me this is a good or a bad thing though. The only thing they did different than me was to fill it up with a cylinder whereas I filled it using a stirrup pump. Surely using a stirrup pump can't have this sort of affect on it can it?

HunterBen Posted December 31, 2014 Report Share Posted December 31, 2014 Same happened to my AT44...air cylinder needs taking off and putting back on tight. Quote Link to comment Share on other sites More sharing options...
bazzashadow Posted December 31, 2014 Report Share Posted December 31, 2014 (edited) great guns very accurate be careful not to go that little bit over 200bar done this on mine and it started to leak just fired it a couple of times and recharged but only to 190bar from then on and £100 more is a lot more money Edited December 31, 2014 by bazzashadow Quote Link to comment Share on other sites More sharing options...
Fabhui Posted January 4, 2015 Author Report Share Posted January 4, 2015 UPDATE - Ok,so I collected my AT44-10 from the shop where they had checked for the leak and couldn't find anything. They filled the cylinder to around 200 bar kept it overnight and it stayed at the same pressure. I left it for a couple of days, took it out and it was still at 200 bar. I fired off around 50 shots which ran it down to just over 100 bar. I put it away for a couple of days and took it out today to use it to find it had dropped to zero! Anyone have any idea as to what the heck is going on with it as I'm at a loss?? Quote Link to comment Share on other sites More sharing options...
