DEVON 5403 lightweight electric hammer, purchased for $8.
The outer shell was badly burned by fire. Fortunately, the main control circuit is basically intact and can be restored to function after simple repairs.
The mechanical parts are fully functional and show little to no wear.
The rotor cooling fan blades were burned, and the main shaft was accidentally damaged during replacement, so the rotor was replaced with a new one.
Finally perfectly restored.
Thanks to the official dealer for helping find accessories.
