Verifying the diesel generator is aligned to provide standby power to the associated shutdown boards.

b.

At least once per 31 days and after each operation of the diesel where the period of operation was greater than or equal to I hour by checking for and removing accumulated water from the engine-mounted i

fuel tanks.

c.
