The X500AJ and X550AJ are very similar models, but not exactly the same.
They share the same basic compact crawler boom lift design and many components, but the "550" typically refers to a slightly higher working height or an updated version with minor improvements (like controls, software, or hydraulics). Manufacturers often tweak model numbers like this to reflect those small changes.
That said, this manual covers both X500AJ and X550AJ, so you’re good either way. Everything from electrical and hydraulic schematics to troubleshooting steps and maintenance procedures is included.
