    • Some roasters have split bowl legs, allowing better access to the motor by removal of the bowl. However, the motor and mount will fit through the hole in the center of the bowl if your roaster does not have split legs.

    • If your bowl is NOT the split leg design, do not attempt to remove the bowl.
