Setup and First Use
- Unpacking: Remove all packaging materials and labels from the tumbler.
- Initial Cleaning: Before first use, wash all parts with warm, soapy water. Rinse thoroughly and allow to air dry. Refer to the 'Care and Maintenance' section for detailed cleaning instructions.
Operating Instructions
Your Stainless King SK1005 tumbler features THERMOS vacuum insulation technology to maintain beverage temperature.
- Filling: Fill the tumbler with your desired hot or cold beverage. For best results with hot beverages, pre-heat the interior with hot water for 5-10 minutes before filling. For cold beverages, pre-chill with cold water.
- Securing the Lid: Place the lid onto the tumbler and twist clockwise until it is securely tightened.
- Using the Drink Lid: The lid features a slide lock mechanism.
- To open for drinking, slide the lever to the 'OPEN' position.
- To close and prevent spills, slide the lever to the 'CLOSE' position. Ensure the lever is fully engaged in the 'CLOSE' position for leak-proof performance.
- Temperature Retention: The tumbler keeps liquids hot for up to 5 hours and cold for up to 18 hours.
Care and Maintenance
Proper care ensures the longevity and performance of your tumbler.
- Daily Cleaning: After each use, rinse the tumbler and lid with warm water.
- Hand Wash Only: The tumbler is not dishwasher safe. Hand wash all parts with warm, soapy water.
- Lid Disassembly for Deep Cleaning: The lid can be disassembled for thorough cleaning.
- Unscrew the lid from the tumbler.
- Carefully remove the silicone gaskets and the internal mechanism by twisting or pulling gently.
- Wash all disassembled parts with warm, soapy water. A small brush or a denture cleaning tablet (as described below) can be used for hard-to-reach areas.
- Rinse all parts thoroughly and allow them to air dry completely before reassembling. Ensure all gaskets are correctly seated to maintain the leak-proof seal.
- Denture Tablet Cleaning (Optional): For stubborn stains or odors, fill the tumbler with water, drop in a denture cleaning tablet, and let it sit for 30 minutes with the lid in the 'OPEN' position (if cleaning the lid simultaneously). Rinse thoroughly multiple times after cleaning.
Troubleshooting
Issue: Tumbler is leaking.
- Solution: Ensure the lid is screwed on tightly and the drink lever is fully in the 'CLOSE' position. Check that all silicone gaskets within the lid are properly seated and free from damage or debris.
Issue: Beverages are not staying hot/cold for the expected duration.
- Solution: Ensure the lid is securely closed. Pre-heating or pre-chilling the tumbler before filling can significantly improve temperature retention. Avoid frequently opening the lid, as this allows temperature to escape.
