1. Air pressure within the cartridge is regulated by an aerator ( aperture C ) which must be sealed to prevent leakage during refilling. Use adhesive tape to seal this aperture.
2. The cartridge is sealed by a plastic or stainless steel ball in aperture B in the top. ( New versions of this cartridge do not have this opening therefore a 3 mm (approx. 1/8") hole must be carefully made in the same position shown ).

Important: If you are making your own hole it must be perfectly round after you make it.

This must be removed by pushing it into the cartridge using a pointed instrument ( e.g. a ball point pen tip ).

Important: The aperture in the centre of the top ( aperture A, see diagram above ) must NOT be pierced.

3. Assemble the syringe and filling needle and fill with ink.
4. The cartridge should now be rested in an upright position on a pad of absorbent tissue ( wad of kitchen roll ) and filled with up to 40 ml. of ink through
aperture B which must then be resealed using the plug supplied. Ink will now drip from the nozzles. Blot the nozzles with the tissue until ink stops dripping.
5. Remove the tape over aperture C, and blot with tissue if necessary.
6. Clean the syringe with water and dry for future use.

Note: Empty cartridges should be refilled immediately.
