To open the coffee maker, lift the spout part up and hold the other (C). Pull out the filter group (A+B), unscrew the filter (A) and fill the shirt (B) with coffee powder. Screw the assembly back in. Fill the chamber (c) to approx. 1/2 cm from the hole opening with water and reinsert the filter unit so that the notch is aligned on the opening. Insert the spout (like a lid). Place the coffee machine on the fire (chamber C must be on the flame). Once boiling is reached, steam (and a few drops of water) will leak out of the hole. Remove the coffee maker from the heat (1) and turn it (2), holding it firmly on both handles. Wait 3 minutes: the water from the chamber seeps onto the ground bottom and allows the extraction of the coffee. Serve by repositioning the lid
