This is my first time with Bosch Impact driver 12V. This one is more quality that Bosch cordless drill with previous video , In this video I fixed the switch, rebuild the battery pack 12V 6400 mAh with new charger, cleaned internal parts, add new grease and clean the impact drill housing. I hope you find something useful & enjoy this video! I am happy to receive your feedback, advice, suggestions to improve myself. !!! I apologize for the mistake if I have made in this restoration !!! ***I still keep some parts, I want to save the world's environment*** ---------------Thank you so much for Likes & Comments---------------
