Good morning to all. I'm Italian and I do not understand English I am using a translator. I'm new and I need help. Unfortunately I have to replace my laser diode but do not know how to disassemble the laser. Someone can help me please? My model is a 820 lm 2000 mw like it in the photos taken from this site for your own writing, I apologize if the photos I post are not mine. How do I remove the diode? Thanks: and sorry if you wreaked disorder.
