GX-E-CS4I clacking

Hello everyone,

unfortunately I don't speak English, so I use a translator for my messages, so please excuse me if some sentences seem incomprehensible.
I have a Vevor compressor which works well, but is very noisy !!!
I recently bought a GX-E-CS4 I compressor and since the beginning when it reaches +/- 100 bar, there is a little “clacking” however it continues to inflate without problem and rises to 300 bar (with the hose plugged in 32 seconds.
But I'm still worried about the clicking sound.
Do you have any idea what the problem might be?
I'll attach a short video sequence if I can!

Thanks to this great community.

Daniel.
