All YOOKERS pens can accommodate either a cartridge or an ink converter except model #751 than takes only cartridges due to its extra slim design Use and maintenance of your Yookers Felt-Tip
Just Four Parts for a simple use!

Your Yookers has a felt-tip section (or roller ball section) , a body ( barrel) a cap, and the cartridge or converter for bottle ink.

Using Your felt-tip pen

The Yookers Felt-Tip should glide across your paper effortlessly. Never apply any pressure on the tip, as it will prematurely wear out the tip. When not writing with your pen, keep it stored vertically with the tip pointing up to prevent ink from settling in and clogging the feed. If you do not intend to use your Felt-Tip Yookers for more than 3-4 days, flush and store it clean. If travelling by plane we recommend a completely empty converter. If a cartridge is already in and you do not want to lose it, keep the tip pointed up. Just like a fountain pen, always keep your pen capped when not in use.

Filling Your Yookers with Ink the first time.

Remove the cap and set aside. Unscrew the barrel by turning it clockwise. There is an upside down cartridge located inside the barrel, remove it and turn it around to fit it the tip hole. The cartridge has one end with a little ball. Place this end into the tip section and press down on a flat surface the flat bottom of the cartridge until you feel a click. The cartridge is now allowing ink to flow to your felt-tip (this might take a few seconds), do not press the tip to accelerate the process, this would be useless and would cause damage to the felt-tip. If you want to use bottle ink, place the converter into the ink and twist to draw ink up into the converter. Remove your converter from the bottle, blot the end a bit and then insert firmly into your tip section. Ink will begin to flow into your Felt-Tip. Again, do not press the tip to accelerate the process, this would be useless and would cause damage to the felt-tip.

Maintaining Your Felt-Tip Pen

Simply remove the front section by unscrewing it from the barrel section. Rinse the front section under a steady stream of water. This will cause residual pigment to leave the tip. Flush until it runs clear. If you haven’t flushed for several cartridges, let the section soak 5 minutes in a cup of HOT water, then rinse under a running tap, redo the whole process a couple more times or as needed. After flushing or soaking, touch the tip to a paper towel and draw the residual water out. When you change ink colors, a quick flush will get you ready for your next color. A quick monthly flush will keep your tip in top condition.

Ink Supply Bottled ink:

Quality ink is the key. Any older ink (more than two years) may cause your flow to slow. Your Yookers prefers thinner inks like Yookers, Kaweco, Monteverde, Waterman, Sheaffer and quite a few others. Black ink contains elements which may cause your tip to dry out. If you prefer to use black ink, stay with a thinner ink like those listed. If your tip does dry out, simply flush and refill

Cartridges:

Any short international standard ink cartridge will work. Flush every two cartridges and your Yookers will flow perfectly.

Storing Your Felt-Tip Yookers

If you don’t plan to use your pen for a prolonged period of time, like a month, empty it out and wash the tip before storing.

How To Maintain your felt-tip pen

Cleaning your fel-tip pen
1.Unscrew the barrel from the tip section.
2.Rinse the tip by filling and emptying it with water (repeat this until the water is clear). Caution: Ink residue will flow out.a.place the tip section into a beaker or other container of clean water and let it soak overnightb.The water level should completely cover the tip.c.Be sure to use room temperature or lukewarm water. Distilled water will work best (tap water sometimes contains particles which may clog the feed). Never use alcohol, as this will damage the feed or other parts of the pen.d.Let the tip soak for 10 to 15 minutes, then blot dry with a paper towel. Soak the tip overnight if necessary.
3.Wash your pen every few weeks or whenever changing ink colors.

Using your felt-tip pen
1.Do not press hard when writing, as this can damage the tip. A good felt-tip pen should glide effortlessly across paper.
2.Use fresh ink. Do not use bottled ink that is more than a year or two old. If you do use older ink, you should first examine it for any mold that may be growing on the surface. Then stir the old ink to make sure that there are no lumps or sediment on the bottom (a sign that the ink is solidifying). Thinner inks, like Waterman, Sheaffer or Pelikan, are less likely to solidify than thicker inks. And if the ink has not been used for several weeks, shake the bottle before filling the converter, as the ink particles may have settled a bit
3.Black ink contains gum arabic. If you allow black ink to dry inside of the tip, it may cause per-manent damage. If you do not plan to use your felt-tip pen for more than a couple of days, clean your felt-tip pen before the ink has dried.
4.Store your ink bottles away from direct sunlight to avoid fading.
5.Avoid using chemically treated paper, which usually has a slick feel, because it does not absorb ink well. Ink will collect in the tip and ultimately clog the feed. If your pen skips after using treated paper, wipe the tip with a lint-free cloth. If this does not work, wash the pen out with water.
6.When traveling by plane, we recommend that you either fill your converter completely or leave it empty to reduce the risk of leakage. Always keep the tip upright during takeoff. When opening your felt-tip pen in flight, you should hold the pen upright and remove the cap slowly. Always keep your pen capped when not in use.
7.If your pen doesn’t “start” right away (i.e., after not being used for a couple of weeks), ink has probably dried and clogged the tip and/or the feed. To start the ink flowing again, resist the urge to press down hard on the pen. Instead, wet the point of the tip with water or ink of the same color. If that doesn’t work, wash the pen out.

Storing your felt-tip pen
1.If you do not plan on using your pen for a prolonged period of time, wash and empty it out before storing it away.
2.When not using the pen, keep it stored vertically (i.e., in a cup) with the tip pointing up to pre-vent ink from settling in and clogging the feed.
