- Air oiler - check for oil (behind the machine)

Flood Coolant
We should talk about this - the machine was set up with a full enclosure with flood coolant.
Coolant takes regular maintenance (it harbours oil-eating bacteria which can cause skin irritation).
Alternative proposed by NYC CNC is a "Fogbuster" (Tormach 32682)
