If you think it's gonna help you, just pay attention
There was a breakdown in household electricity, a failure of electric cars and a failure of spare parts, and many first responded by looking directly for a repair shop. The door-to-door fees, testing fees and spare parts costs are set up, and prices are often prohibitively high. Sometimes a small failure takes hundreds of large repairs to open. Many of them were simply minor problems because they did not understand the internal structure and had to accept the offer passively。
Most do not know that there is an open web site dedicated to sharing maintenance information on the internet. It includes not only household electricity, digital, vehicle maintenance steps, but also industrial machinery, engineering equipment, even maintenance manuals for civil aviation aircraft, and a course for dismantling。
It is, of course, important to make it clear here that ordinary people cannot repair aircraft themselves. Aircraft maintenance is a strictly licensed professional industry and private private self-maintenance aircraft is an offence. What we can think of is the idea of open sharing of technical information behind it。
Today, this article is written in plain language to clarify what the free maintenance website is, what it can find, how it can be used rationally by ordinary people, what it can do on its own, what it can never touch, and the traps it contains in self-study maintenance. After that, the next time the household items are broken, it is possible to check the data to determine the failure and avoid being asked for prices。
I. Why the purpose in the maintenance sector
In the impression of many, maintenance is a bad information business。
A washing machine is not activated, and the reasons for the failure are many, and it is possible that only the power lines are loosed and the switches are poorly exposed and that a few dollars can be fixed. It may also be that the main plate was burned, and several hundred pieces were needed to replace it. Consumers who do not understand internal principles simply cannot distinguish between the magnitude of the failure. The maintenance master said that ordinary people can only pay passively。
For a long time, the maintenance drawings, dismantling steps and failure codes of a large number of equipment have only been in the hands of brands and authorized repair sites. It is very difficult for ordinary consumers to obtain a manual for the maintenance of the plant。
Many brands create maintenance barriers when products are designed. The casings were specially screwd, which could not be opened with ordinary tools; the main plate did not indicate the parameters of the parts and, if damaged, only official accessories could be purchased。
The advantage of doing so is that manufacturers can firmly control markets after sale, and the downside is that the cost of self-maintenance by consumers is high。
In recent years, the global “maintenance rights” movement has emerged. An increasing number of countries have introduced provisions requiring manufacturers to make basic maintenance information publicly available and to allow general users and third-party maintenance masters to obtain equipment drawings and failure statements。
A large number of pro bono, free and non-profit information-sharing sites have emerged. They are maintained by engineers, maintenance masters and technology lovers worldwide. Small to earphones, remote controls, large to truck, excavators, aviation equipment, and heavy maintenance files are all open free of charge。
That is, the technical database known on the internet as “can be found even in the building of a flight course”。
Ii. What exactly does this free maintenance site have
The first reaction was a bit exaggerated when many heard that the aircraft maintenance course was available, and we objectively divided the information from the website。
Most of the so-called aircraft maintenance materials on the website are civil aviation public versions of maintenance manuals, spare parts structure charts, regular maintenance processes, and failure clearance lists。
These materials are in themselves internal training materials for the aviation industry, many of which are publicly available in the industry and are not classified as direct driving, private adaptation aircraft。
The physical maintenance of aircraft must be carried out by professionally trained and qualified crews using specialized tools in compliance sites. Even with the complete maintenance manual, ordinary people are not entitled to repair the vehicle。
In addition to aviation information, the content of the website, which is truly accessible to ordinary people, is divided into six main categories。
Category i. Information on maintenance of household appliances。
Refrigerators, air conditioners, washing machines, water heaters, microwave stoves, electromagnetic furnaces, smoke machines. It includes a complete decomposition step, how the shell is to be removed, a circuit board map, various sensor parameters, and a common failure code explanation。
The e1 and e2 malfunction codes, which ejected on many air conditioners screens, were clearly stated in the maintenance manual and the corresponding damage to the spare parts was apparent。
The second category, digital electronics, dismantles the curriculum。
Cell phones, laptops, tablets, bluetooth headphones, monitors. Detailed graphics, video dismantling steps, screw position, line card position, battery replacement method。
When the information is removed, those with the ability to do so can replace their own cell phone batteries, screens and save a high maintenance fee。
Category iii, transportation maintenance documentation。
Two-wheeled electric cars, motorcycles, domestic cars, vans. Engine structure chart, oil-routing method, maintenance cycle, spare parts model。
A number of simple maintenance projects on domestic cars can be completed by replacing air- and air-conditioning cores。
Category iv, industrial equipment and hardware machinery。
Generators, welders, air presses, pumps, cutters, agricultural machinery. Equipment assembly drawings, common failure screening process。
This information is very useful for users of processing plants and agricultural machinery。
Category v: manual for the maintenance of medical and experimental equipment。
Description of basic maintenance of blood pressurers, detectors, laboratory instruments. Note that medical professional equipment is not recommended for private maintenance by non-professionals and is suitable for basic maintenance reference。
Category vi: large engineering, transport, aviation maintenance files。
Trains, ship engine maintenance and civil aviation passenger aircraft regularly maintain manuals. This type of information is only suitable for technical enthusiasts and has no practical value。
It is important that you set your mind straight, that the web site is a resource search tool and that you are not hand-held with high-risk equipment. It's a reference. It doesn't mean you have maintenance qualifications。
Iii. Learning to use free maintenance materials and what tangible benefits ordinary people can get
A lot of people say it's too much work to do. In fact, access to maintenance information does not mean that it is necessary to dismantle the machine itself. Even if you don't do it yourself and find out in advance, you can avoid repairing many of the holes。
The first is to understand the malfunctions and reject blind consumption。
To give a very common example, air conditioning in the home is suddenly not cool. The maintenance master went to the door and said that the compressor had broken down and that it would take more than 1,000 to replace the compressor。
You checked the failure code for the air conditioner in advance and found that the error was just a sensor failure, so dozens of pieces of fittings could be repaired. If you had basic failure information, you wouldn't have been overrated and wasted。
Second, simple failure, low-cost self-repair。
There are many failures in life that are not repairable at all, but poor exposure, loose circuits and filter congestion。
The water heater hinted at the failure, except that entering the filter was blocked by the mud; the washing machine reported errors, except the drain was blocked by coins and hair。
After reading the curriculum, he cleaned himself up for five minutes without paying any fee for maintenance。
Thirdly, the purchase of spare parts is no longer overpriced。
Many of the prices for spare parts for maintenance stores are much higher than those for retail online。
If you use the maintenance manual, you find the exact type of the damaged parts. The individual parts are placed on the internet and only manual fees are charged to the maintenance master. Overall maintenance costs can be saved by more than half。
Fourth, extend the useful life of old household electricity。
Many old-age electricity has long been out of production and official sales no longer provide maintenance services. The maintenance information at the plant is difficult to find, and many of the old models were archived in the free database a decade ago. With these old materials, many old-fashioned home appliances and old tools can continue to be used to reduce the direct waste and waste of goods。
Fifthly, the technical lovers learn a trade of their own。
There are a number of ordinary people who want to study maintenance and crafts, and they do not have the money to enrol in expensive courses. These big free manuals are good self-learning material. It is also possible to develop into a side business over a long period of time to understand the structure of the circuits and the mechanics。
Four, you can fix anything. Don't touch anything
Understanding maintenance information does not mean that any equipment can be removed. The maintenance has clear, secure red lines, which, when crossed, are prone to hazards such as electrocution, fire and explosion. I divide the maintenance risk into three levels, which you can refer to。
Level one, security risks are low and ordinary people can try。
There is no danger after the power outage of such equipment, and even if the operation fails, the most equipment is not working and does not harm the safety of the person。
Clean up washing machine drains, replace remote control batteries, replace cell phone batteries, replace air filter cores, clean air-conditioning filters, strengthen table and chair furniture screws。
Ordinary people can do this on their own, as long as they operate according to the course steps and complete the power outage。
Second, there is a certain risk that those who are capable of doing things will try carefully。
220 volts of electrical circuit boards, external spare parts for gas heaters, electric brakes and light lines。
The maintenance must be preceded by a complete blackout and strictly in accordance with the curriculum. There is no electricity base and it is not recommended to touch the main circuit section。
If the internal lines are found to be very old after being dismantled, they are stopped directly and handed over to professional maintenance staff。
Level 3, high-risk equipment, which is restricted to ordinary people, is strictly prohibited from breaking and repairing themselves。
First, high-voltage power, high-power industrial power, high-voltage cabinets. In the event of an operational error, there will be direct electrocution。
Second, the gas wall hanger, gas pipeline, gas stoves, gas route component. The self-discovery of airways is prone to gas leaks and explosions. Gas repairs must be handled by certified staff of gas companies。
Thirdly, car airbags, gas routes, brake systems. Once the brakes and airbags are installed in error, major traffic accidents occur when driving。
Fourth, all types of manned aircraft, aircraft, drone power systems. The maintenance of aircraft is subject to strict legal norms, and it is against the law to modify the personal maintenance。
Fifthly, medical treatment equipment. Mismaintenance of therapeutic instruments directly affects health。
For these high-risk categories, the maintenance manual can only serve as a science learning resource and in no way as a practical guide。
V. Free maintenance of information websites, and what is used the pit
Everything that's free on the internet is shortboards and traps. The maintenance of the information website is also not perfect, and the common problems are set out here。
The first issue, the old version of the information, was not matching the model。
For the same household electricity, the internal circuit boards of different production batches will be modified. You downloaded a maintenance manual five years ago and got a reference to the new machine, the location of the parts and the distribution of the lines. The complete maintenance of the curriculum can easily be repaired。
The maintenance information can only be used as a reference and cannot be rigid。
The second problem is that partial scans are vague and images are missing。
Many of the old manuals are manually scanned for uploading by lovers, blurry images, unclear text and missing key steps. The maintenance of the missing data makes it easy to judge errors。
Thirdly, there are mixed advertisements and fishing links on free websites。
Some of the pages that are in the name of free maintenance materials, when they click on the downloads, they pop up a lot of advertisements to induce you to download bound software. The virus is installed in computers and mobile phones。
When downloading information, the regular non-profit database is recognized and not randomly clicked on the bullet window。
Fourth, some brands are reluctant to publicly repair drawings。
Some of the new high-end household appliances and digital products have not been published at all. The corresponding model is not available on the website. This situation can only be addressed after the official sale。
Fifth error: understand drawings = have maintenance capability。
The drawings only tell you what the parts look like and where the screws are. Physical maintenance also requires specialized tools, welding techniques and circuit testing experience. Many circuit boards fail, and even if the drawings are in front of you, you can't find any damage。
Do not overestimate your ability to do it. Complex malfunctions are stopped in time for professional masters to handle。
Vi. General personnel search for maintenance information and complete operational steps
Many have never used such technology websites and do not know where to start. I'll give you a common search line。
First step, confirm the complete equipment model。
The entire product model is printed on the back of the device. It is known that washing machines and air conditioners are far from sufficient and that complete models must be entered to find a matching maintenance manual. With one letter, the internal structure is completely different。
Step two, open the maintenance information website and enter the full product model in the search box。
The search will be followed by the release of the maintenance manual, the dismantling guide, the malfunction code sheet. Priority is given to the PDF manual issued by the original plant, which has the highest level of accuracy。
The maintenance notes uploaded by third-party netizens can only be used as a reference。
Step three, give priority to the fail code description。
When equipment is faulty, an explanation of the failure code is sought. Whether it's a glitch or a glitch. There's no need to come up and take the whole thing apart。
Step four, assess maintenance difficulties and safety risks。
Once the maintenance steps have been completed, it is self-assessed that there are no corresponding tools and security risks. If high pressure, gas, oil roads are involved, self-maintenance is abandoned。
Step five, identify the type of spare parts and compare the cost of maintenance。
Upon identification of the damaged spare parts model, the price of the spare parts is checked online. The cost of spare parts, combined with the time spent on its own, would be more economical if the difference between maintenance costs and maintenance costs for teachers were not significant。
Vii. Consumer thinking behind the right to repair
In recent years, “maintenance difficulties” of products have become common to many. Many manufacturers deliberately designed the product as a one-time consumer, which was difficult to untangle, spare parts were unavailable and maintenance offers were close to buying a new machine. In the end, you can only choose to change things directly。
Frequent changes of seemingly convenient nature actually result in large amounts of electronic waste and waste of resources。
The most important point of opening up maintenance materials and lowering maintenance thresholds is to break the post-sale monopoly。
When consumers can easily identify the cause of the failure, the third-party maintenance industry can compete in good faith and the price of maintenance will naturally be reasonable。
This is not to encourage all people to become maintenance masters, but to give consumers the right to know and choose。
You can either fix it yourself or you can pay for it. But you shouldn't have passively accepted the bid without knowing it。
The disclosure of technical information is essentially about returning the right to transparency to ordinary consumers。
Viii. Final summary
The so-called free website has a curriculum for even repairing aircraft, which in itself is somewhat exaggerated. All that can be found on the website is the public maintenance and maintenance of documents for aviation equipment, not the teaching of maintenance that ordinary people can practice。
For us in general, the greatest value of such websites is not for repairing large machinery. Instead, it gives us an additional channel of reference for information when small household electricity and digital products fail。
Maintenance information is a tool and the tool itself is not good or bad. Reasonable utilization can help avoid maintenance packages and save considerable maintenance costs。
But we must keep the safety threshold in mind. High-risk equipment, such as high-voltage circuits, gas-fired equipment, car brakes, aircraft, etc., is not taught and is not repaired。
If you know the principles, know the risks, and you can do it yourself, you should pay for it. It is the most rational way to learn how to maintain one's own self-help without being blind or risking repairing high-risk equipment。
In an era of free disclosure of technical knowledge, a little more understanding of the principles of equipment reduces the likelihood of information-based harvesting。
