- Lubricate moving parts if recommended by the manufacturer and ensure all components are properly aligned.

Ensure contacts, switches, and wiring are clean and free from dirt or corrosion. Use a soft brush or compressed air for cleaning. Reconnect loose wires securely, and inspect the circuit board if accessible.
Test and Finalize
- Reassemble all parts, insert a fully charged battery, and test the tool in a controlled environment.
