Operating Instructions
Once the adapter is properly connected to both the vacuum cleaner and a power outlet, it will begin to supply power to the device or charge its battery. The charging indicator on your vacuum cleaner (if present) will typically illuminate to show charging status.
- For charging, allow sufficient time for the vacuum cleaner's battery to fully charge. Refer to your vacuum cleaner's manual for specific charging times.
- The adapter can also be used to power the vacuum cleaner directly if it supports operation while plugged in.
- Always unplug the adapter from the wall outlet when charging is complete or when the device is not in use for extended periods.
Maintenance
- Cleaning: Disconnect the adapter from all power sources before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or aerosols.
- Storage: Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures. 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.
