Hey Softcraw,

The continuous beep is overheating. Intermittent beeping is oil. You could actually be overheating or you could have a bad sensor. The heat sensors are mounted on the powerhead and do go bad occassionally. Any of these problems can be checked out by a good mechanic. You really want to get this checked out though, could be serious in the case of overheating or it could be just a bad sensor (best case). I had an intermittent beep on mine, got out the shop manual and studied. Finally found a small tear in my oil line from the main tank. Replaced the line, problem solved. Had a friend who chose to ignore his sensors and well let me say this, he ended up buying a new Optimax.

Later and good fishing,
