The fat is now really in the fire. The rake arms are buried in mud, and the feed will have to be cut until the thickener has been unloaded. When unloaded, the arms have to be raised until the thickener mechanism will again turn. Following this, the pump must be speeded up to help draw down the sludge load as fast as possible.
