If you are authorized to add a master item, go to the Maint Items page by navigating to Admin | System Admin | Maint Items. This is the page in which you can add new scheduled maintenance items.
When adding an item, you need to specify when to be notified in terms of how many hobbs/tach hours before and/or how many days before. If you enter both hours before and days before, Schedule Master will send out notifications on whichever event occurs first.
If the maintenance is marked as mandatory, this item will be considered in determining the color of the hazard symbol on the schedule page. Any overdue items will cause the hazard symbol to be red.
Note: Authorized users includes sysops and those with the 'Scheduled Maintenance Admin' authorization.
