Filling with a cartridge
Unscrew the barrel from the nib section. Push the cartridge firmly into the back of the nib section until it clicks or snaps. Screw the barrel back on. Nib down, wait 30 seconds for ink to reach the nib. Write a few circles on scrap paper until the ink flows.
Filling with a converter and bottled ink
Attach the converter to the nib section as you would a cartridge. Dip the entire nib and the nib section (not the whole pen) into the ink. Turn the converter piston slowly to fill - you will see ink rise. Pull the pen from the ink, wipe the nib with a cloth or paper towel, and cap. You are ready.
Cleaning a fountain pen
When changing ink or putting the pen away for more than a month: unscrew the barrel, remove the converter, hold the nib section under a slow stream of cold water until the water runs clear. No soap, no hot water. Run the converter through a rinse cycle the same way. Let everything air dry before reloading.
Reviving a dry nib
If the pen has been sitting dry: fill the converter with water, fit it to the pen and write on scrap paper until the nib flows. If it still skips, soak the nib section in a glass of cold water for an hour. Dried ink dissolves in water; no special solvents are needed.
