Maximathor .25 air tank removal

About 3/4 down the page he Pope-on-Dope explains how to remove, I considered one of these as my first PCP.


"Hi NevadaRocks,congratulations – yeah, it´s a sweet little gun. A far as the cylinder is concerned: Walther doesn´t recommend it, that´s right – but it can be done with ease. Just unscrew the mini screw on the underside of the barrel band (the thing with the “T” on it) with a metric allen key (its a 2 mm one, I believe). If you don´t have one, a small screwdriver should do the job but be careful – if anybody notices that the reservoir was unscrewed, it might void your warranty. Better ask your dealer how he looks at it.Then turn the reservoir counterclockwise. I had one MaximaThor in my hand where is was very easy and on the other one which is my own it was a pain in the @$$ to unscrew it – you will not lose any air so the reservoir can be filled, no problem. Be careful to return the reservoir to its original position (the screw should have left a mark on the air reservoir). I recommend you to get a new longer air hose because with the low shot count, it will soon become annoying to unscrew the dang thing every single time. Concerning the article in the Australian magazine – it is clearly not correct. See my chrony test above, the Walther MaximaThor is clearly NOT regulated, no way a regulated gun would give you an increase of speed with practically every shot. And Walther specifies that this gun is not regulated. "

I own one of these behemoths and have never had the need to remove the stock. I find it absurd that the air cylinder must be removed before separating the stock and action. I have just had the whole cylinder replaced under warranty after something in the fill valve broke or came loose. Why they replaced the whole cylinder and not just the faulty part, I can only guess that they don't keep many spares, which is another thing that worries me as the warranty here in Australia is only 12 months. I'm starting to think that PCP airguns are not worth the risk once the warranty runs out.
