Carefully remove the plastic cover from the blade as it is very sharp! Always hold it by the upper plastic part and handle it carefully. To connect the chopper bowl and the hand blender, place the blade on the center pin of the chopper bowl, press it down and give it a turn so that it locks into place. Fill the chopper with food and put on the lid. Align the chopper with the motor part and push them together until they click.
When chopping is complete, unplug and press the release buttons to detach the motor part. Lift the lid up and carefully take out the blade before pouring out the contents of the bowl. To remove the blade, slightly turn it then pull it off.
