Here are filling instructions for "Piston Fill" fountain pens, including Pelikan and many others: Turn barrel end cap to the right (clockwise) as far as it will go. Place entire nib and half the section into the ink. Turn knob to the left (counterclockwise) while the nib is still in the ink. Remove nib from the ink and turn knob to the right - just far enough to bleed out a couple of drops of ink. Tighten knob back down. Remove from the ink and wipe nib after filling. Always place cap onto the pen with the nib pointing up, do not put the pen into the cap with the nib pointing down - this will prevent ink from getting into the cap.
