Setup
- Unpacking: Carefully remove the toaster and all packaging materials. Ensure all accessories are present and the toaster is free from damage.
- Placement: Place the toaster on a stable, flat, heat-resistant surface, away from flammable materials such as curtains or walls. Ensure adequate ventilation around the appliance.
- Initial Cleaning: Wipe the exterior of the toaster with a damp cloth. Do not use abrasive cleaners. Remove and clean the crumb trays (see Maintenance section).
- First Use (Burn-off Cycle): Before first use, operate the toaster without bread on the highest setting (Level 6) for a few minutes. This will burn off any manufacturing residues and may produce a slight odor or smoke, which is normal. Ensure the area is well-ventilated.
Operating Instructions
The Keenstone 4-slice toaster features two independent control panels, allowing you to toast different items simultaneously or use only two slots at a time.

Maintenance and Cleaning
Regular cleaning ensures optimal performance and extends the life of your toaster.
- Always unplug the toaster from the power outlet and allow it to cool completely before cleaning.
- Crumb Trays: The toaster is equipped with two removable crumb trays. Pull out the trays from the bottom rear of the toaster. Discard crumbs and wipe the trays clean with a damp cloth. Dry thoroughly before reinserting.
- Exterior: Wipe the exterior surfaces with a soft, damp cloth. For stubborn stains, a mild non-abrasive cleaner can be used. Do not use metal scouring pads or abrasive cleaners, as they may scratch the stainless steel finish.
- Interior: Never insert any objects into the toaster slots to clean. If food becomes lodged, unplug the toaster and carefully remove the item once the toaster is cool.
- Do not immerse the toaster in water or any other liquid.
