PSI for 10.5 in rivet set

I?ve never used a 10.5? set to drive AN 470 ( 4-5 and 4-7). rivets. Is there an approximate psi setting to drive these rivets with this long set?
Thanks

I do not have a specific PSI number for you but I typically would take the PSI up 10 -15 PSI when using longer drivers and more than that if the the long driver also has any offset. Too low pressure and you will start to work harden the rivet prior to getting the correct shop head. Pull the trigger for a few hits and check to ensure the rivet head is forming, if not raise the pressure.

Good luck
