Got a dive tank, iv put it back together temporary and just filled it , but it's at around 220 bar , but it's output is very poor , I can watch the pellet leave the gun and hit its target ,looks like a slow motion film ;( any ideas ?

 

Think you're overfilling at 220.

Try filling to 180ish and see.

Higher fill pressure can cause lower power till it gets down a bit

:good: max fill pressure 190bar power drops off above this. As suggested 180 is good. Also don't let pressure drop to less than around 90bar or you risk the valve opening and dumping what's left.

as said above keep it to 190 ish or 180. if the seal want re-seated because of low presure, stick it on a dive bottle and give it a quick blast but dont over fill. it always worked for me. also as said it will lose power when over filled so find its sweet spot and stick to it and you should be fine.

New seals is a good move. Ive just given my s410 another service with all new seals - i replaced all the seals about 3 years back and was really surprised at how worn out they looked yesterday. As others have said, when refilling, try cocking first. Also, dont fill over 190 as it will not improve performance.

 

I put mine all back together yesterday, filled to 190 and my first 10 shots were about 6 ft / lb!!! After about 20 more shots, this slowly crept up to nearly 13ft lb. So i immediately backed the power down to about 11.5ft lb on the adjuster - did a few more shots to check. Thats why I always recommend people should get a chrono as you never know what sort of power you`ll get after a service.

 

When I get some spare time hopefully at the weekend I plan to do a full shot count on mine and plot the ft lb to see how it performs.
