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
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 33).
• 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.

• 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 polarized plug (one
prong is wider than the other), which fits
into a polarized outlet only one way. If the
plug does not fit, reverse the plug. If it still
does not fit, do not use the plug in that
outlet. Do not alter 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).

Shake Reminder How to Shake
What to Shake
SHAKING FOOD
• The Shake Reminder is designed to
remind you to check on your food,
usually to shake it. Press SHAKE to turn
on the Shake Reminder.
• You can use the Shake Reminder with
any cooking function except Preheat and
Toast. We especially recommend using
the Shake Reminder with the Air Fry
function (see page 16).
• The Shake Reminder will appear halfway
through cooking time.
• If SHAKE is pressed during cooking, it will
appear halfway through the remaining
cooking time.
• The Shake Reminder will alert you with
several beeps, and “(Shake)” will blink on
the display.
• The Shake Reminder will go away once
you open the oven door to take out the
basket.
• Add the Shake Reminder to your cooking
function by pressing SHAKE.
• We recommend using the fry basket if
you are shaking food. You can optionally
use the rack or tray instead.
• When the Shake Reminder appears, take
the fry basket out of the oven and shake,
mix, or flip the food.
• To shake food, hold the basket just
above a heat-resistant surface for safety
purposes. Then, shake the basket.
• If the basket is too heavy to shake, place
the basket on a heat-resistant holder or
surface. Then, shake the basket. Do not
use this method if there is a risk of hot
liquids splashing.
• If the basket is too heavy to shake and
there are hot liquids present, place the
basket on a heat-resistant holder or
surface. Use tongs to mix or flip the food.
• When you open the oven door to take out
the basket, the oven will pause cooking
automatically. When you close the door,
cooking will automatically resume.
• Avoid shaking longer than 30 seconds, as
the oven may start to cool down.
• Small foods that are stacked, such as fries
or nuggets, will usually need shaking.
• Without shaking, food may not be crispy
or evenly cooked.
• You can flip other food, such as steak, to
ensure even browning.

Dark smoke is coming out of
the oven.
Immediately press and unplug your oven. Food is burning.
Wait for smoke to clear before opening the oven door.
A thermometer shows that the
