Used babyplast commissioning

I have recently purchased an used babyplast machine that I couldn't see work because it was too far away from where I live. Have little knowledge on injection molding process and zero experience on using it but I'm not new to machines in general but I work with machines from a totally different businnes.

I have read about purging and the machine seems to still have plastic in it. The manual is in spanish but I can translate it.

Is there something to clean/refill before I even think to turn it on?
