The lid sits crooked or wobbles

The lid overhangs to one side, or wobbles

• Wobbles, or comes off when opened: the wing nuts are loose. Tighten them clockwise by hand with the lid fully open (this guide's reading of the manual; Monolith lists no such fault).
• Overhangs to one side: re-seat the lid first, then turn the bands back in their groove. Ceramic has small tolerances, and transport can turn the bands.
