Hohner Pirola iii. Issues with air button

[AccordionPlayer23]

Hi everyone.
I have piano accordion hohner pirola 3. I noticed that air button doesn't close valve completely. How can I fix it?

Hiya,
I think the Pirola is the same construction as the Lucia (but more notes etc).
If youre happy doing DIY you need to take the bass shell off and see what the problem is.

I absolutely love this type of bass mechanism that is so easy to repair!
In Italian mechanisms you need to disassemble everything bit by bit to work on it, and even disassemble a large part of it just to get access to the air button...

Yep, I like the bass machine removable too.

Something I spotted a while back: Scandalli started using removable bass machines in the 60s.

That page has issues, I found opening it twice it worked 2nd time.

Heres another site I found from George Whitfield that says Scandalli had a removable bass in the 40s.

That air button always get stuck against the borders, it also happens with lucia and atlantic models. All you have to do, is to bend the button in a way it doesn't get stuck again, or sand the hole with the dremel tool to make it bigger

Re Scandalli....some older Scandalli bass mechanisms have little rubber loops pushed over the end of the pistons, to keep them in place. When these perish (and they do) they are a real pain in the neck to deal with. Not a very sensible design.
