2. Setup
2.1 Unpacking and Component Check
Carefully remove all components from the packaging. Ensure you have the following:
- Trash Can Base
- Trash Can Ring Liner
- Trash Can Lid (with motion sensor)
2.2 Battery Installation
The lid requires batteries for operation. Locate the battery compartment on the underside of the lid. Insert the required batteries (not included) according to the polarity indicators. Ensure the battery compartment cover is securely closed after installation.
2.3 Installing the Trash Bag
- Place a standard 13-gallon trash bag into the trash can base.
- Fit the removable ring liner over the top edge of the trash bag, securing the bag in place. This ring helps to keep the bag hidden from view for a neat appearance.
- Carefully place the lid assembly onto the trash can base, ensuring it is properly aligned and seated.

3. Operating Instructions
3.1 Powering On/Off
Locate the power switch, typically on the back or underside of the lid. Flip the switch to the 'ON' position to activate the motion sensor. Flip to 'OFF' to deactivate.
3.2 Automatic Motion Sensor Operation
When the trash can is powered on, the infrared motion sensor will detect movement within a 10-inch range and a 130-degree angle. The lid will automatically open. It will remain open as long as motion is detected within the sensor's range. Approximately three seconds after motion ceases, the lid will close automatically.

3.3 Manual Open/Close
For extended periods of use or specific situations, you can manually control the lid:
- Press the OPEN button on the lid to keep it open indefinitely.
- Press the CLOSE button to close the lid when it is in the manual open state.
4. Maintenance
4.1 Cleaning
To maintain the appearance and functionality of your Ninestars trash can:
- Wipe the stainless steel body with a soft, damp cloth and a mild cleaner. The fingerprint-resistant surface helps keep it smudge-free.
- Regularly wipe the infrared sensor with a dry cloth to ensure optimal performance.
- Clean the interior of the trash can base as needed.
4.2 Battery Replacement
When the lid mechanism becomes sluggish or stops responding, it is likely time to replace the batteries. Power off the unit, replace all batteries with new ones of the correct type and size, and then power it back on. Battery life typically lasts at least 6 months with normal daily usage.
5. Troubleshooting
Lid Does Not Open
- Ensure the power switch is in the 'ON' position.
- Check if the batteries are placed correctly and are not depleted. Replace if necessary.
- Wipe the motion sensor with a dry cloth to remove any obstructions or dirt.
