What are the main safety precautions I need to know before using the Big Blue 500?

Key safety precautions include: only qualified persons should install, operate, and maintain the unit; disconnect input power or stop the engine before servicing; never touch live electrical parts and wear dry, hole-free insulating gloves; keep everybody away from the equipment during operation; use proper grounding and inspect cords frequently for damage; and allow proper cooling periods before working on hot equipment. Additional precautions are needed in damp locations, confined spaces, or cramped positions.
