6. Operating Instructions
Once connected, the adapter will begin to supply power to your Gevi cordless vacuum cleaner and charge its internal battery. The charging indicator on your vacuum cleaner (if present) will show the charging status.
- Charging Time: Refer to your Gevi vacuum cleaner's manual for typical charging times.
- Battery Condition: Please note that rechargeable batteries have a finite lifespan, typically 1 to 3 years. If your vacuum cleaner's battery is old or degraded, it may not accept a charge, which is a battery issue, not an adapter malfunction.
- Disconnecting: To disconnect, first unplug the adapter from the wall outlet, then remove the barrel connector from your vacuum cleaner.
7. Maintenance
- Cleaning: Disconnect the adapter from all power sources before cleaning. Use a soft, dry cloth to wipe the adapter. Do not use liquid cleaners or solvents.
- Storage: When not in use, store the adapter in a cool, dry place, away from direct sunlight and moisture. Avoid tightly coiling the cable to prevent damage.
- Cable Care: Do not bend, twist, or pull the cable excessively, especially near the connectors, as this can cause internal damage.
8. Troubleshooting
- Device Not Charging:
- Ensure the adapter is securely plugged into both the wall outlet and the vacuum cleaner.
- Test the wall outlet with another device to confirm it is functional.
- Verify that the adapter's specifications match your vacuum cleaner's requirements.
- As mentioned, an old or faulty battery in the vacuum cleaner may prevent charging. This is not an adapter defect.
- Adapter Overheating: If the adapter feels excessively hot, disconnect it immediately. Ensure it is not covered and has adequate ventilation. If overheating persists, discontinue use and contact support.
