The company does pay for the new cartridge and blade, we currently have three in stock and hope we never need one due to an injury. We assume that the employee (associate is the company term) is trying to work safe.

We keep the spares because wet wood can trip the sensor. Also any conductive material such as lexan laminated with aluminum.

It can be run inactive depending on the startup from power off. I am going from memory of the demo we had but there is a main disconnect and an on/off switch. Possibly the alternate mode is when you have non seasoned lumber and do not want to chance tripping the blade.
