To assemble the instrument, place the case in a safe place where it cannot fall (table, counter). Avoid placing the case on your lap to assemble the flute.
Take the flute body out of the box, holding it with your right hand and the headjoint with your left hand, and fit them together. Avoid holding the body by the mechanism as it is a fragile part, hold the body by the upper part where the flute mark is engraved. Next step is to remove the foot of the flute and fit it in the body of the flute. Hold the Flute Foot in its lower part where it has no mechanism.
With the flute assembled, it is necessary to align the headjoint hole towards the first key of the flute body and the foot axis to the middle of the last key of the flute body. Check the photo below where the line indicates the correct alignment.
