Backup power fails quietly before the outage
Run hours, oil, battery, and load-test notes belong on one page because standby generators can sit for months and still need regular exercise.
The Fuel / stabilizer column is especially useful for portable units. Old gas is a common failure point when the lights are already out.
Use the footer for oil type, spark plug, and critical circuits so the person starting the generator has the same facts as the person who maintains it.
