Yes, you can upload your 50-page, in fact, 100-page manual PDF to Claude, and the platform will not see it as a large task. Claude has been designed for this type of long document review task. Just upload your PDF manual and ask for a summary, and Claude will create a quality summary. Just a suggestion, do not simply ask Claude to summarise everything at once, instead provide Claude with specific questions to help him focus his analysis. For example, highlight important points, summarise by section and recommendations from the summary.
