Duration
Check the correct state of the motor every six months.
● Check the motor for any damage.
● Perform any necessary maintenance work.
● Check the state of the dehydrating agent and replace when necessary.
● Record the preservation work so that all preservation coating can be removed prior to the
commissioning.
