- Extreme caution must be used when moving an appliance containing hot oil or other hot liquids.
- Do not use appliance for other than intended use.
- Always attach plug to appliance first, then plug cord into the wall outlet. To disconnect, turn any control to “off,” then remove plug from wall outlet.

Setup and First Use
Unpacking
Carefully remove the toaster oven and all accessories from the packaging. Ensure all packing materials, including any protective films or inserts, are removed from the appliance before use. Verify that all components listed in the 'Included Components' section are present.
Placement
Place the toaster oven on a flat, stable, heat-resistant surface. Ensure there is adequate ventilation around the appliance, with at least 4-6 inches of clearance on all sides and above to prevent overheating. Do not place it directly against a wall or under cabinets.
Initial Cleaning
Before first use, wipe down the interior and exterior of the toaster oven with a damp cloth. Wash the baking pan and wire rack in warm, soapy water, then rinse and dry thoroughly. Ensure the removable crumb tray is properly inserted.

First Use (Burn-Off)
It is normal for a new toaster oven to emit a slight odor or smoke during its first use. This is due to the burning off of manufacturing residues. To minimize this, operate the oven empty on the 'Bake' function at 450°F (230°C) for approximately 15 minutes. Ensure the area is well-ventilated during this process.
Operating Instructions
The Oster TSSTTVVGS1 features user-friendly control dials for various cooking functions.

Control Dials
- Temperature Control Dial: Located at the top, this dial allows you to select the desired cooking temperature from 150°F to 450°F.
- Function Selector Dial: The middle dial selects the cooking mode: Broil, Bake, or Toast.
- Timer Dial: The bottom dial sets the cooking time up to 30 minutes. For continuous operation, select 'Stay On'. For toasting, turn past 10 and then back to the desired toast shade (light to dark).
Cooking Functions
- Toast: Ideal for bread, bagels, and frozen waffles. Place items directly on the wire rack. Select 'Toast' function, set the temperature to 450°F, and adjust the timer for desired browning. The oven has a 4-slice capacity.
- Bake: Use for casseroles, cookies, and reheating. Place food in the baking pan on the wire rack. Select 'Bake' function, set the desired temperature, and set the timer.
- Broil: Perfect for melting cheese, browning toppings, or cooking thin cuts of meat. Place food on the baking pan. Select 'Broil' function, set the temperature to 450°F, and set the timer. Monitor food closely as broiling is a fast cooking method.

Care and Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your toaster oven.
Cleaning the Interior
Always unplug the appliance and allow it to cool completely before cleaning. Remove the wire rack and baking pan. The interior walls can be wiped with a damp cloth and mild liquid soap. For stubborn stains, use a non-abrasive cleaner. Do not use metal scouring pads or harsh chemicals.
Cleaning the Removable Crumb Tray
The removable crumb tray slides out from the bottom front of the oven. Pull it out, discard crumbs, and wash it in warm, soapy water. Rinse and dry thoroughly before reinserting. This feature simplifies cleanup and helps prevent grease buildup.

Cleaning the Exterior
Wipe the exterior surfaces with a damp cloth and dry thoroughly. Do not use abrasive cleaners or polishes that may scratch the stainless steel finish.
Troubleshooting
- Appliance does not turn on: Ensure the power cord is securely plugged into a working electrical outlet. Check your household circuit breaker.
- Uneven toasting/cooking: Ensure food is placed centrally on the rack. Preheat the oven for a few minutes before adding food for more consistent results. Adjust cooking time and temperature as needed.
- Smoke or odor during operation: A slight odor is normal during first use. If excessive smoke occurs, unplug the oven immediately. Check for food spills or debris on heating elements or crumb tray. Ensure the crumb tray is clean.
- Timer not working: Ensure the timer dial is turned past the '10' mark and then back to the desired setting for toasting, or directly to the desired time for baking/broiling. For continuous operation, select 'Stay On'.
