Sioux 2x & 3x rivet gun problem?

[Vincenzo]

Hi everyone!
i have a question about my sioux rivet gun:

every time he is connected to air plant,
the gun releases a small amount of air from the exhaust (i dont touch the trigger). is normal?

a video to explain better:

Thank you

Sounds like the trigger is leaking air. Did you buy it new? If so has it always done that? For the money you paid, I'd send it back to Sioux to have it fixed. Sioux has great tools.

I bought new by Brown tool two month ago, I wrote to them to have an opinion, until now no answer ...

The exhaust is leaking air.
