Follow basic safety precautions when using your smart air fryer toaster oven.
Read all instructions.
IMPORTANT SAFEGUARDS
Key Safety Points
General Safety
• Do not touch hot surfaces. Use
handle.
• The outside of the oven, including
the door, is hot during and after use.
• Always use heat-resistant gloves,
pads, or oven mitts when handling
hot materials, and when placing
items in or removing items from
the oven, including trays, racks,
accessories, or containers.
• When the oven is not in use, and
before cleaning, press
START/CANCEL to turn it o, then
unplug from outlet. Allow to cool
completely before putting on or
taking o parts.
• Do not immerse the housing, cord,
or plug in water or liquid.
• Closely supervise children near the
oven.
• Do not use your oven if it is
damaged, not working, or if the
cord or plug is damaged. Contact
Customer Support (see page 30).
READ AND SAVE THESE
INSTRUCTIONS
• Do not use third-party replacement
parts or accessories, as this may
cause injuries.
• Do not use outdoors.
• Do not place the oven or any of its
parts on a stove, near gas or electric
burners, or inside another heated
oven.
• Be extremely cautious when
removing a tray, basket, or rack if it
contains hot oil, grease, or other hot
liquids.
• Do not clean with metal scouring
pads. Metal fragments can break o
the pad and touch electrical parts,
creating a risk of electric shock.
• Clean the crumb tray after using.
Accumulated grease and crumbs can
overheat and catch fire.
• Do not store anything on top of
your oven while it is operating.
Do not store anything inside your
oven other than recommended
accessories.
• Do not operate with a separate
remote-control system.
• Only use as directed in this manual.
• Not for commercial use. Household
use only.

5
• Do not place oversized foods or
metal utensils (except for Cosori
accessories) into your oven.
• Do not place paper, cardboard, or
non-heat-resistant plastic into your
oven, or any materials which may
catch fire or melt.
• To avoid overheating, do not use
metal foil in the oven unless directed.
Use extreme caution when using
foil, and always fit foil as securely
as possible. If the foil contacts the
oven’s heating elements, this can
cause overheating and risk of fire.
• Never put baking or parchment
paper into the oven without food on
top. Air circulation can cause paper
to move and touch heating elements.
• Always use heat-safe containers.
Be extremely cautious if using
containers that aren’t metal or glass.
• Keep your oven away from
flammable materials (curtains,
tablecloths, walls, etc.). Use on a flat,
stable, heat-resistant surface away
from heat sources or liquids.
• Immediately turn o and unplug
your oven if you see dark smoke
coming out. Food is burning. Wait for
smoke to clear before opening the
oven door.
• Your oven has a 3-prong grounding
plug, and should only be used with
120V, 60Hz electrical systems in
North America. Always plug in to a
grounded electrical outlet. Do not
modify the plug in any way.
• Do not let the power cord (or any
extension cord) hang over the edge
of a table or counter, or touch hot
surfaces.
While Cooking Plug & Cord
Electromagnetic Fields (EMF)
This oven complies with all standards
regarding electromagnetic fields (EMF).
If handled properly and according to
the instructions in this user manual,
the appliance is safe to use based on
scientific evidence available today.
Note: This oven uses a short power-supply cord
to reduce the risk of entangling or tripping. Use
extension cords with care. The marked electrical
rating of the extension cord must be as great as the
rating of the oven (see page 3).
