It is necessary to assess the situation. If the backpack is intact and can still serve, it will not be difficult to repair it. It all depends on the severity of the breakdown, which is easy to fix yourself, would be improvised materials.
We’ll show you how to fix a zipper on a backpack.
Possible lightning malfunctions
First you need to find out what happened to the castle. There may be several reasons for the breakdown. The main types of malfunctions include:
- destruction of the lower limiter;
- runner breakdown;
- the exit of the teeth from its position.
REFERENCE. The main reason for the breakdown of the castle is the wear of its internal elements and components.
This happens due to mechanical damage, when the fastening occurs abruptly, with the use of physical force.
The condition of the fastener can also be affected by sudden changes in temperature, affecting the structure of the material from which the links or lock are made .
Erasing surfaces, increasing the distance between components, and microcracks are also frequent. As well as dirt and dust, worsening the work of the dog, and the break of its suspension, because of which it is impossible to exert due force on the links of the chain.
Ways to repair lightning
First you need to understand the type of fasteners, as they are different, depending on the type and style of the product.
HELP . Snake-zippers are divided into three groups: metal, spiral, tractor.
Repair tools
To fix the malfunction you will need:
- interchangeable lock with suspension;
- measuring device in the form of a ruler or economic centimeter;
- screwdriver;
- clamping tools;
- hammer;
- scissors.
Repair
Highlights for troubleshooting include the following:
- Zoom in and pinch the increased distance between the links with pliers, which will also help in the repair of the lower limiter.
- Hammers tighten the gaps.
Replacing the slider.
Using a small hammer, gently hit the edges of the castle, trying not to fall into its center. For the best effect, clamping occurs on both sides with a solid stop. This method is designed for metal zippers . The same principle of a firm stop occurs with pliers.
ATTENTION! Actions are performed as accurately and accurately as possible so as not to break the part.
If the problem occurred due to the fault of the castle, it changes. To begin with, the slider’s characteristic and its number are determined, or a ruler measures it to buy the same in the store.
Algorithm for installing a new lock
- The zipper is unfastened.
- The limiter is removed.
- The new slider is inserted correctly.
- Pliers compresses the removed limiter.
- Refueling tape.
The technology of its removal and replacement depends on the type of snake . For metal zippers, replacement cannot occur without a screwdriver or scissors to cut a thick tape. With other species, the principle of replacing a dog is similar. The only difference between the spiral clasp is that to improve the glide, lubricate the tape with paraffin, soft lead or even fat. But the latter methods are only suitable for leather or dermatine backpacks.
Breakdown prevention
To prevent the fastener from failing, the following rules must be observed.
- Carefully fasten and unzip the slider.
- If the metal snake has just begun to diverge, repair is done using a vise or other clamp.
- The backpack must be zipped for washing.
- Use wax or pencil for preventive purposes.
- Monitor the cleanliness and operation of the mechanism.
Performing proper care of the snake and properly conducting repairs, you can carry your favorite comfortable backpack for a long time.
