Air Arms S510 TDR

[Duaney]

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 had a quick look
S510r TDR 250bar fill
S510 TDR 190bar fill
You might have the wrong handbook, stay safe. Rog

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

You did the right thing to check though, better safe than sorry Cheers Rog

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."
