Your saber comes almost completely assembled. The only step required is attaching and securing the blade to the hilt. The process of doing it is similar for all saber models. The number of screws and their location can vary between models.
Please make sure not to cross thread the screws as it will damage the threads in the emitter.
Torque the screws gradually instead of fully torquing each screw right away.
Important: You only need to use the short screws to secure the Polycarbonate blade in the hilt. The other screws are spares that you might need if you remove the core from the hilt.
To charge the saber unscrew the handle from the hilt to expose the USB-C charging port. Use the provided charging cable and use a low power USB outlet to ensure the saber does not overheat.
