What are the key electrical safety precautions a technician must follow when servicing the KSM150?

All disassembly and assembly procedures must be conducted with the unit disconnected from the AC mains. The power cord should always be inspected first, and the mixer must never be run if the power cord is damaged — it must be replaced. Technicians should also wear protective eyewear at all times and avoid loose-fitting clothing or bracelets during service. (Page 2)
