14.4V Brushless Impact Driver Restoration | Hitachi WH14DBL

Brushless Impact Driver Restoration Video
I found this tool from Japan recycle shop only 15$. It is 14 4V Brushless Impact Driver - Hitachi WH14DBL. The battery charger don't work, I think it was plugged in 220v outlet. There are 2 batteries come with, there are only one can be reuse. About the driver is need to clean, change the bearing and add new grease to gearbox. At the end of video you will see how it works.

I hope you find something useful & enjoy this video!
I am happy to receive your feedback, advice, suggestions to improve myself.
