Vintage Battery Impact Wrench Modernization | Makita 6902D

I found this impact wrench from Japan recycle shop without the battery. There is a power cord between the tool and the battery, it may not easy to use. I believe that it isn’t easy to find the original battery pack. I decide to modify the way of using battery from cord to cordless way. Furthermore, I hope you find this video useful and enjoy it! Additionally, I am happy to receive feedback, suggestions to improve myself. !!! I’m sorry for the mistake if I did in this video !!! Thank you very much for choosing to watch my video! Have a nice day Gear Show
