After some time, after about 3 hours of pure yo-yoing time, it is good to replace the string. The old string no longer has such a strong color as the new one, it is greasy, dirty, inflexible and overall looks a lot used. You can tell easily, with a used string you are no longer feeling well. Try to untangle the knots as soon as they form. If this is not possible, replace the string.
Once you have determined that the string needs to be replaced, here’s how to do it. You grab the yoyo in your left hand and start untangling the string near the yoyo with your right hand. After a while, the eyelet around the bearing should be visible as it gradually enlarges. When the eyelet is wide enough, you can take it off the yoyo. So you don’t have to unscrew the Yoyo at all and it will last you much longer. Perform the same procedure with a new string. You grab it by the right end (not the one with the loop) and start twisting it slowly until a small eyelet appears at the end, which you then drag over the yoyo. You then roll the string back on the yoyo.
Sometimes it’s a good idea to shorten the string, especially to smaller yoyers, so that they don’t hit the ground so much and can yoy at all. The recommended length of the string is from the navel to the ground, for smaller yoyers, on the other hand, we recommend having the string a little longer. When the yoyo with the string is lying on the ground, grab the string by the navel and fold it. At this end, you make a classic knot so that the loop that is created there is neither too long nor too short, about 2 cm. Tighten the knot tightly and cut off the excess end. This created a new loop for you to pass through the rest of the string, and now you have a tightening loop that you attach to your finger.
