1. do not open and close smoothly, if the head of the chain pulling force, will have teeth engaging element failure. This time with paraffin or lubricant spray [zip with (FASTENERMATE)] is applied to the tooth surface and the inside, and then move the slider after the slide several times loose.
2. Zipper bag stuff loaded on too long, if combined with a zipper closure, zip force too big, the teeth out of band member. This zipper malfunction, be serious. The left and right tooth member closer, so close together easily head fastener chain after the adoption.
3. when opening and closing the fastener, the first bite and sometimes chain segment or leaving the cloth slider pull them in this case, if you want to pull a strong pull, the more will bite deeper, it should on the one hand to pull the head backwards, State and untied the cloth. Fully bite into it, do not force pulling big slider, slider backwards slowly please. Likewise when sewing zippers, do not have to stay hidden.
4. dressed a long time zipper does not work well, because the zipper slider becomes loose lead, and this time you can use pliers (no teeth pliers can also be used) pinch the slider, so that the slider becomes tight, zipper will be easy to use.
