JCB 212SU air filter buzzer problems

Just new to the forum. I have JCB 212SU I just bought this year for snow. Machine has been great, changed all filters, fluids etc when purchased. One outing the warning buzzer started coming on and off periodically mainly at higher RPM, checked filtered a little dirty nothing crazy so replaced both in and outer filter. Didn't seem to change much though I did notice the filter gauge thingy that you push in to reset seem a little loose and tightened it. Now it seems to happen very randomly at high rpm, just idling, sometimes when roading it from lot to lot it comes and goes.



Just curious if anyone has any suggestions in what the issue could be.



Thanks in advance
