Feeding a 200-page manual into any tool produces a vague course. Splitting well is the most important step.
Split by job, not by chapter
Group content by the tasks people do. A manual's chapters often follow the system's structure; training should follow the learner's day.
One source per course
Make each course from one focused source section. Coursecast handles up to 40 PDF pages or about 60,000 characters per draft, which is a good natural limit.
Connect the pieces
Give each short course the same objective style and a one-line "where this fits" intro, so learners see the path.
Keep the source map
Write down which section each course came from. When the manual changes, you'll know which course to redraft.
