Air Arms S510 TDR

Mon Sep 14, 2020 12:36 pm

Hi guys I just bought an Air Arms S510 TDR from my local dealer very pleased with it previously I had an S410 both in .177.
On looking in the manual that came with it it says fill to 250 bar, now my 410 I filled to 190 bar
it seems a little high as I don't want to blow the seals so I'm filling to the same as my 410 ie 190 bar.
What do you think?

Thanks

I think your right 👍
I think they made a reg'd TDR that uses higher pressure
But it would say S510r the r being reg'd
Just as an aside, I never fill my TDRs to 190bar, more like 165/170bar, where my sweet spot starts

Just realised mine is the regulated version so 250Bar is right oops.

Yes it is not helped by the manual for the TDR R stating:

"The filling pressure of the S􏰑􏰐􏰓510 R TDR high power is 2􏰑50 bar (3􏰔626psi)"

Mine is a sub-12ft.lb. model not the XS and on first reading I thought that the 250 bar was for the 'high power' - i.e. XS version.

It would appear all regulated versions are therefore fillable to 250 bar.

What is important is to USE THE FILL GAUGE ON THE BOTTLE not the gun:

"The on board gauge should not be used during the filling process as the needle reaction speed has been slowed to prevent damage whilst filling."
