Repair Hitachi Electric Screwdriver DB 3DL2 Recovery Function 

Hitachi 3.6V folding screwdriver
The switch has poor contact and the hand guard glue has fallen off.
It was completely disassembled and the interior was relatively new and clean. I simply cleaned it and used lambskin instead of hand gel.
The switch can be restored to function after disassembly and cleaning.
Reprint and paste worn label paper.
