4. Operation

Once connected, the adapter will begin charging your Shark vacuum's battery. The charging time will depend on the battery's current charge level and capacity. Always refer to your vacuum's user manual for specific charging instructions and battery care.

Charging: Allow the vacuum to charge fully before its first use or after extended periods of non-use.
Unplugging: When charging is complete, unplug the adapter from the wall outlet first, then disconnect it from the vacuum.
Storage: Store the adapter in a cool, dry place when not in use.

5. Maintenance

Cleaning: Disconnect the adapter from the power source and the vacuum before cleaning. Wipe the adapter with a dry, soft cloth. Do not use liquid cleaners or solvents.
Cord Care: Avoid bending, twisting, or crimping the power cord excessively. Do not place heavy objects on the cord.
Inspection: Periodically inspect the adapter, cord, and connectors for any signs of damage, such as cuts, fraying, or loose connections. If damage is found, discontinue use and replace the adapter.

6. Troubleshooting

If you encounter issues with your adapter, please review the following common problems and solutions:

Problem	Possible Cause / Solution
Adapter not charging the vacuum.	Ensure the adapter is fully plugged into both the wall outlet and the vacuum. Check if the wall outlet is functional by plugging in another device. Verify that your vacuum model is listed as compatible. Battery Issue: Rechargeable batteries have a limited lifespan (typically 1 to 3 years). If the vacuum's battery is old or dead, it may not accept a charge. This is a battery issue, not an adapter issue. You may need to test the battery or consult your vacuum's manufacturer for battery replacement. Adapter Fault: If the above steps do not resolve the issue, the adapter may be faulty.
Adapter feels hot during use.	It is normal for adapters to become warm during operation. Ensure the adapter is in a well-ventilated area and not covered. If it becomes excessively hot to touch, disconnect it immediately and contact support.
LED light on adapter is off.	Check power connections to the wall outlet and the adapter. Test the wall outlet with another device. The LED indicates power to the adapter. If it's off, the adapter may not be receiving power or could be faulty.

If you are unsure whether the battery or charger is at fault, a voltmeter can be used to test the charger's output voltage. If issues persist, please contact customer support.
