the secrets of how to distinguish genuine Bosch tools from good knockoffs
The German brand Bosch is loved by many users for its high quality products, durability, ergonomics and durability. Naturally, in every country there are enterprising businessmen who want to profit from other people’s labor. We mean the companies involved in counterfeiting of well-known brands. So, today no one is surprised that bought an angle grinder in Kharkov Bosch will not be Bosch, and a strange piece of plastic flimsy construction with a disgusting smell. Therefore, having decided to buy an electric screwdriver or other Bosch tool, you should verify its authenticity yourself, especially not trusting the sellers.
A WORLDWIDE INVASION OF “PIRATES”. MANUFACTURERS OF ELECTRO- AND GASOLINE POWER TOOLS SOUND THE ALARM !
Manufacturers of pirate (counterfeit) products threaten not only the well-known companies with loss of income and reputational damage. Fakes are also dangerous for customers, because they are not only extremely unreliable in their work, but often dangerous to health.
SIMPLE TRUTH. What is the risk of encountering a counterfeit?? Well, the fact that in quality it may not be inferior or superior to the original, is rejected at once. Because then the idea itself dies: no one will work at a loss, and it makes no sense to overprice, because it is cheaper to buy the original in a store. The threat first of all in such things as lack of reliability and safety guarantees. the manufacturer, when they put the ELECTRONIC TOOL in your hands, is responsible for any malfunction not caused by you. Even if the malfunction hangs on the owner himself, it can be fixed in the SERVICE CENTER. Who’s responsible for the counterfeit you’ve sold?? Savings on materials and homemade assembly can lead to premature failures, malfunctioning of the ELECTRONIC INSTRUMENT.
But this is insignificant against the backdrop of a more global thing. electrical safety. There is no need to go into detail about the importance of the issue, it’s all obvious. By the way, there are examples when unsuspecting people were sold a fake with a motor whose armature was without double insulation, which could lead to electrocution if the motor was damaged. Fakes are not profitable for the manufacturers, either. After all, there are questions of reputation and perhaps financial gain involved. Poor quality plastics, labels glued on loosely, brushes that need to be replaced twice as often, backlashes. all this leads to the conclusion that you are not holding a PROFESSIONAL ELECTRONIC TOOL, but a cheap toy. It begs the question: what is the money for??! By the way, it is not worth judging the brand by the products that this manufacturer did not produce. To be fair it should be noted that there were cases when the counterfeit completely satisfied the owner, and about the counterfeit he found out only in the SERVICE CENTER. But this. Pretty quality fakes.
IS AN EXCEPTION THAT PROVES THE RULE. However, there are examples with quality not worse than the original. Actually it is the original TOOLS we are talking about. With one “but”: they are imported illegally. It is probably not necessary to be afraid of them, but it is better not to mess with them. Where do they come from?? The thing is that the same ELECTRONIC TOOL model is supplied to several regions at once (Russia, Asia, etc.), but it is not the only one.д.), so it is adapted for them. For example, the mains voltage is not the same in all countries. As a result the buyer receives a good quality product, just not certified for Russia. No PCT mark. It is possible to work with it, but to repair it in a SERVICE CENTER under warranty will not work. Can refuse even in paid repair.
WHO? WHERE? WHY? To avoid falling into the hands of fraudsters, you need to know the signs of counterfeiting. However, you can reduce the risk even before the inspection of goods by giving preference to the trusted sales outlets. But first of all it is necessary to understand where ELECTRONIC TOOLS are sold in general.
Tents at the construction market and small stores.
A fertile ground for the sale of fakes. Such outlets work by the method of re-buying: take in one place for one price, sold in their place for another. the mechanism is very clear and worked out for years. But is there any guarantee that the product was made, for example, in Makita factory in England and not somewhere in Ukraine? After all, it’s just a reseller, not an official dealer. It is logical that selling fakes in such places is very profitable. People often go to the market, not very sophisticated in toolmaking. That is why even the obvious signs of counterfeiting will certainly not arouse everyone’s suspicions.
There is a perception that, “by definition,” low-grade merchandise is sold here. Nevertheless, if the hypermarket is officially cooperating with a particular company, there is no reason not to trust it. Still, rumors abound. There have been cases where someone tried to sell counterfeit goods in the parking lot of the hypermarket. Well, the advertising slogan “There is IKEA. there is an idea” is one hundred percent justified, except that this time it was embodied in an undesirable way.
As in the previous case, everything is simple. If such a retail outlet is recommended by the representative office, then you can give it preference. The list of such stores and addresses can be found on the Russian-language website of the brand. As for representative offices, they often don’t sell ELECTRONIC INSTRUMENTS and can only send them to the nearest official store.
The most democratic way. You don’t have to go anywhere. delivery is often free. But you can’t hold in your hands what you are paying for and you can’t assess the quality of workmanship of a specific item. And this is the key criterion by which a fake is recognized. Conclusion: If you have already decided to take advantage of the World Wide Web, look for happiness in reputable stores, and not chase the low price. It’s easy to sell counterfeits over the Internet.
precisely. from strangers for cheap. Such ELECTRONIC TOOLS are popularly referred to as TSYGANTULS. as they are often offered by gypsies or persons of Caucasian nationality. By and large, there’s not even a question of whether it’s a real Bosch or a Makita. It all comes down to whether there is at least a percentage chance that you are not offered a counterfeit or criminal of another kind. They find the buyer themselves. Sometimes they offer an individual model, sometimes. whole set. The locations of these acts of mercy are chosen wisely. the same hypermarket parking lots, construction markets. But not just. Sometimes standing by the side of a railway crossing. Often we see this picture along the highways. In general, the purchase of such a product is better to refuse at once. The possibility of running into a stolen second-hand product is too high. By the way, they steal PROFESSIONAL ELEKTROINSTRUMENT willingly. It is no coincidence that some manufacturers even put on models similar to immobilizers (for example, the Code system at Metabo ).
In short, popular products from well-known manufacturers. It is another matter who is considered famous. Without detracting from the popularity of brands like FESTOOL. Metabo or MILWAUKEE (and other famous brands), most often imitated Bosch and Makita. This is the ELECTRIC POWER PLAYER HR2450. angle grinder (angle grinder) 9069. CIRCULAR SAW 5704R. from Makita ; the GBH 2-26 Series ELECTRIC POWER PLAYERS. GBH 11 DE and HAMMERDRILL-32 machines from Bosch (although Bosch does not have such a model in its official line). There are some knockoffs of HILTI machines: TE 76-ATS ELECTRIC POWER PLAYERS. TE 56-ATS and angle grinder (angle grinder) DS 230-S. Recently the most “popular” became PETROL PULLS from Swedish concern Husqvarna and German STIHL. There are plenty of “real” BENZOPILs: 365XP. 5200. 373XP, etc. д. As you can see, bushmen have a priority. ELECTRIC TEAMS. As for brands DeWALT or KRESS. The representatives of these brands don’t complain about fakes. Of the budget products, the attention of underground craftsmen was attracted, in particular, by ELECTRIC DRILL “Interskol” D-350ER and ELECTROBUSIC “FIOLENT” MP4-700E. This applies to ELECTRONIC TOOLS. But there are also counterfeit accessories! For example, counterfeited “Luzhskie” abrasive wheels for angle grinder (BOLGARO) and saw blades for Bosch. It’s easy to guess why you should not mess with such products, because low-quality Saw blades can be broken off in no time.
One question remains unanswered: how to recognize a counterfeit? Depending on the quality of its manufacture, the way it is made may be different. Let’s deal in order.
2) Как отличить подделку от оригинала Bosch GBH 2 26 DFR, GBH 2 26 DRE / Немного про смазки
The nameplate. Nameplate. is a plate on the TOOL body, which contains technical data of the TOOL, place of its assembly and other information. If it is glued upside down, loose, or made underhand (for example, printed on a printer). These are sure signs of a fake. However, if the place and year of manufacture of the ELECTROINSTRUMENT are not indicated on the nameplate, you should not jump to conclusions. Most DeWALT models in particular do not have this information. The only geographical indication is IDSTEN, GERMANY. But it has nothing to do with the place of assembly.
Product code (on the nameplate). If it does not exist or the ELECTRONIC TOOL with this code is not in the range of the manufacturer, it means that most likely you are holding a counterfeit. The presence of hieroglyphs should also be alert.
CE and PCT marks on the nameplate. Should be a must. Their absence means at least that the INSTRUMENT is not certified for use in Russia. At most. You guessed it yourself.
Non-existent name. It happens that they sell imitations of non-existent TOOLS. For example by opening the catalog of Bosch. It is not difficult to find the Bosch HAMMER DRILL ELECTRIC POWER LEADER models. There are no 32 in nature. Artisans have their own assortment.
The way the name of the driver is printed. Thus, the word Bosch on the original TOOL of the company is made in the form of raised raised letters, on a fake or its case. a simple sticker. Other external signs. It can be a low-quality plastic with burrs (those who have held a genuine model in their hands, by such a sign will quickly identify a fake) or suspicious color of the case of the ELECTROINSTRUMENT. In general, if you have any doubts and not at all about the apartment of Comrade Shpak, it makes sense to re-insure. The same counterfeit Bosch is found in both blue and black shades. Unusual design and shape of the case. “Fantastic” models like the ELECTRIC PEOPLE in the form of a rectangular block with a handle. not a hallucination at all, but just an amusing imitation. However, when it comes to names like SKIL. unusual appearance should not be misleading. Unoriginal case. Each case is worth looking at individually. For example, the HILTI case has raised ribs and the manufacturer’s name engraved in large letters. But you have to know beforehand, otherwise you won’t be able to tell a fake from the wrong size, font or missing ribs. RUSSIAN LANGUAGE INSTRUCTIONS or original warranty card. They should be obligatory! Sets. In particular, a set in the form of an angle grinder (angle grinder). You can reject the Bosch electric drill and electric drill bit right away. The official Bosch does not sell such kits.
Suspicious place of assembly. Makita models, for example. assembled in Russia. Nothing to think about. fakes! precisely, the TOOLS themselves may have been assembled in Russia, but they have nothing to do with the official Makita line. Bosch in Russia assembles only Electric Impact Drill GSB 13 RE and Electric Scissor GST 75 BE.
Suspicious Components. In particular, one of the fake variations of Makita HR2450 ELECTRIC POWER PLAYER has an incomprehensible attachment on the plug, and the rubber cover on the housing is not a cover at all, but only painted plastic. Exception. Sometimes even the original can stand out with a non-standard coloring. For example, a recent series of Interskol ELECTRIC DRILLS in gold shade. Or the Bosch GSH 27 BETONOLOM with the yellow housing.
The above is a list of external signs. But on the inside, believe me, there are just as many differences and they play a much more important role. But to recognize them you have to: a) disassemble the ELECTRIC TOOL. b) know how everything should look on the original machine. Some things will only be seen by a SERVICE CENTER, but there are more obvious signs. This includes:
Rough and uneven balancing on the motor armature. You can see it for yourself. Fakes are also calculated by the irregular location of the balancing kerfs. But here a footnote should be made to point “b” of the previous paragraph.
The color of the wire insulation. For example, one of the fake Makita HR2450 ELECTRIC PERATORs has the same color (white) wires running from the switch assembly to the stator and rotor. They are colored on the original. This can also include a non-standard switch.
CONCLUSIONS AND RECOMMENDATIONS: Counterfeit as well as cheap ELECTRONIC TOOLS, as a rule, of well-known brands. most often “copied” are ELECTRIC POWER SWITCHES. The SERVICE CENTER may refuse to repair a counterfeit even at a cost, since no one will give you a guarantee of electrical safety. It is possible to recognize a fake! If you do not want to get mixed up with a counterfeit, it is better to drive to the nearest recommended store or hypermarket. You should not buy an ELECTRONIC TOOL from a suspicious person. Feel cheated? We would like to discuss the quality of counterfeit power tools with their sellers? Please go to! But it doesn’t hurt to have proof. Contact an AUTHORIZED SERVICE CENTER. Where they will write you a report that the product is counterfeit.
Bosch screwdrivers: Malfunctions as a result of prolonged use
The popularity of automating the process of installing and dismantling structures has given rise to mass production of devices with an electric motor. The manufacture of screwdrivers is engaged in a large number of companies from different countries around the world. The German power tool manufacturers Bosch has got the first place.
the screwdrivers of this company are distinguished by high-grade components, quality construction and long life. It is as a result of prolonged and intensive use that one or another problem may appear. It is connected with the exhaustion of a part or assembly of the motor life.
The most common faults in Bosch screwdrivers are:
- Battery failure;
- Failure of the starter button;
- wear of parts of the planetary gearbox;
- Damage to the quick-release chuck;
- motor failure.
Start button repair
- The easiest and most practical way to repair a defective start button on an electric screwdriver is to replace it completely.
- After acquiring the original part, the battery is disassembled. To do this, loosen the screws on the perimeter of the housing and remove the top of the battery, gaining access to the button.
- Now it must be unsoldered from the motor and remove the connector that connects the switch to the power supply.
- After that, the wires from the electric motor are soldered in place, and the new button is installed in the housing along with the connector.
- Then the tool should be tested and the body should be reassembled.
One of the main components of the power tool is considered to be the power source. In an electric screwdriver it is the battery. It is a battery of galvanic cells connected in series, which are made in the form of cylindrical cans. The size of a single cell is 33 or 43 mm in height and 23 mm in diameter. The number of banks is determined by the battery voltage of the tool’s battery assembly:
Battery bank: troubleshooting
Detecting battery damage is not difficult. It is enough to measure its voltage after a full charge. The voltage of one battery bank is 1.3 volts. the voltage of a fully charged 12-bar battery should be 15.6 to 15.7 volts. If the voltage is insufficient, it is a signal to further check the battery:
- To do this unscrew the fixing screws on the housing and take out the cassette with the banks.
- Visually inspect the galvanic elements for oxidation and damage.
- Then measure the voltage of each bank. If there is no voltage on one or more of them, they must be replaced immediately.
Important! Banks in the battery are connected in series, so damage to one element entails the failure of the rest.
- Armed with a soldering iron, you must remove everything that can prevent the removal of the punctured bank: the plus wire and temperature sensor. To avoid a short circuit, it is better to insulate the power wire.
- Now you need to detach the plates that are welded to the battery, align them for a better contact.
- After that the contacts need to be tin plated. To reduce the time and temperature of heating, it is advisable to use flux F38m. A small amount of it is put on the contact plate and liquid solder is added. As it spreads over the surface, it will cure the contact. Do this on both sides of the top and bottom contact plates.
- After that, the battery bank itself must be prepared. Apply flux at the point of contact with the contact. The plate with the heated solder must be pressed against the can at the top end. And the same should be done with the lower contact.
- After that you need to restore the temperature sensor and the plus contact. Then proceed to reassemble the repaired battery.
Battery bank: restoration of the primary processes
If battery bank is not punctured, but lags behind by 10% according to voltmeter readings, you can try to reanimate it. As a result of prolonged use under the influence of high loads, some banks dry out. It is necessary to activate them and restore all the processes taking place in the tank.
In addition, often another option is used. A hole is drilled in the can and distilled water is added with a syringe. After that the cell is left for a day. After a specified time, the battery is repeatedly discharged and charged. The hole is caulked with silicone.
Another option to return the battery to its operational parameters is to mechanically attack each individual cell. It is easily squeezed or deformed. This method does not solve the problem, but for a while the battery is restored.
Repair of battery charger
To restore the serviceability of rechargeable batteries on the power tool the charger is used. Bosch screwdrivers are no exception. One of the screwdriver failures is considered to be a charger failure.
The symptoms are as follows. The battery is placed on charge. The device is turned on for just a few minutes, and then turns off, indicating that the charging process is complete. The battery remains discharged.
To find out the cause of the failure it is necessary:
- Disassemble the case of the charger by removing the 4 self tapping screws. It consists of two compartments. In the first one there is a transformer and in the second one. the control board of the device.
- Now you need to apply voltage to the transformer and measure the amperage. If it matches the rating, go to the next step.
- As a rule, the control chip and the rectifier in this case are good, so you need to check the power connectors at the time of operation of the device. To each contact you need to solder a thin wire. They will allow you to measure the voltage during the operation of the device.
- Turn on the charger and measure the amperage. If the readings are unstable, up to complete disappearance, then the reason is the bending of the power terminals due to prolonged use of the device.
Restoring the contact will allow you to get a full charging process.
