To rebuild residual, the machine needs to be run, preferable near full load, for a few hours.  Good maintenance would include doing so a couple tims a year.  I try to do that will all of my bigger rental units (20 kva and up) although the large ones are difficult to load near full.  That rebuilds residual.  Brushless generators do sometimes need to be flashed. Dropping generator or striking a field pole will destroy the magnetism in the steel core of any genset.  Magnetism is, afterall the alignmentof the charges in the steel, and a sudden impact will "scramble" that alignment.  I'm glad I've been able to take part in this discussion.  In the future I won't believe nearly all that I read.
