Hi LD. I recently bought a used white rotary unit made by you. I really like the quality, and performance is very good. However, the vibrations and noise from the compressor is pretty high, I guess that's the trade off you get when aiming for performance Is there anything I can do to make it less noisy? What's the optimal tension in the compressor mount screws? it seems rather loose now. p.s. your inbox is full.
