What safety switch should always be in the off position when a hand crank is placed on the crank shaft?

Main idea: cut power before you engage a hand crank so nothing can start or move unexpectedly. Setting the safety switch to off removes electrical power from the drive, ensuring the motor cannot start and the crank cannot be driven. This is the safest state when you’re placing a hand crank on the shaft because it prevents accidental motion that could injure you. Being in a neutral position doesn’t guarantee de-energization in all systems, and turning it on would energize the drive. Locked isn’t a standard safe position for this step. So, keeping the switch off creates a completely safe, inert condition for manual work.
