The appliance is powered down and the power cords are disconnected before
•
you open the air baffle cover.
The air baffle assembly is always installed in the appliance except when you

cover.
When the air baffle assembly is installed in the appliance, the air baffle cover

working inside the appliance.

Do not drop any metallic objects, such as paper clips, hairpins, or screws, into
•
the appliance.
Be aware that there are hazardous moving parts exposed inside the appliance
