First you need to return the dog to the place. Dress up her to tape the same place where she jumped. Then you need to hem the edges of the tape where the slider flies, thread to match the fabric or lightning. Thus limiter will prevent the thread from the dog jump off from.
Another common problem is when lightning begins to diverge. Most likely one or more teeth were loosened a bit and began to bulge above the belt. From this gap in the runner increased, and the dog became worse to cope with its task. In this case, change the zipper is not entirely necessary.
To fix, you must first pass along the buttoned zipper light hammer blows from the inside and the outside several times. This will align the teeth on the tape. Followed by gently compress pawl pliers to reduce the distance between the upper and lower planes. If we apply too much force, the slider will not stand and broke in half.
If after such repair lightning again begin to diverge, it is possible to replace only the slider. To do this, first remove constraints to lightning, shoot the dog, put on new and recycled back stoppers.
Sometimes a zipper fly off the teeth. This can cause a variety of problems to buckle. The dog may get stuck in places or lightning may diverge. Sometimes it is possible to fix this kind of problem.
On nylon zippers can replace the missing teeth turns thick line. You can also fix and plastic zipper. For metal fasteners missing teeth transplanted with old unused lightning, but this is not always possible to.
If lightning broke away from the tissue, it should be neatly hemmed by a machine or a conventional needle.
On new clothes lightning often seize or close unevenly and with difficulty. To fix the zipper enough to go 1-2 times with soap and water inside and outside. Zipper appears peculiar lubricant that will not damage the fabric, but will prevent friction between the slider and teeth.
