Volcano issue..

Hello..after years I finnaly caved in and ordered the volcano...I have owned it for 2 weeks now.. I ordered the classic solid valve.. It is very nice but I am having an issue

No matter what I do the top screen+metal rise because of the vibration from the motor

like pictured here

I have tryed even using a minimal amount and have had the same issue.. This is causing it to be far less powerful then it is capable and even causing bits to shoot out.. I cannot be the only one who has run into this problem.. I cannot find anything on google
