For more details on the warranty conditions, please refer to the warranty card that comes with each stitching machine. Also, for each stitching machine, you will be given an operating manual in Russian.

The main malfunctions of Renz binders:

A typical problem is, as practice has shown, mechanical breakage of the plastic strap of the bookbinder, which is responsible for the release of the springs. This breakdown can be eliminated only in the conditions of a service center, since an appropriate tool and qualifications of an engineer are required.

In addition, Renz bookbinding machines are distinguished by a heavier bed, which is a big plus for bookbinding. But at the same time, because of this, the repair becomes more complicated, because to replace the strap, it is necessary to completely dismantle the machine and further adjust the spring release mechanism directly. But in our conditions, these works are carried out in the shortest possible time thanks to the accumulated experience and the availability of spare parts.

And the third defect encountered is poor perforation of some holes. This is already a factor of machine wear associated with blunting of punches. This malfunction is eliminated by replacing the corresponding punches, which, by the way, have different lengths for uniform force on the handle when punching holes.

We have listed malfunctions that are related to the time and rules of operation of bookbinding machines. And in no way detract from all the advantages of Renz office equipment.

Our authorized service center also provides post-warranty repair of bookbinding machines, brochures, binders, as well as repair and maintenance of office equipment, shredders, cutters, copiers, printers.

In a modern office or even at home, it is more and more common to find a bookbinding machine or brochure. This device is also often referred to as a booklet maker.It is extremely useful if you need to connect several sheets and give them a presentable look. The brochure is often used by students who need to prepare and execute an essay, term paper or thesis, as well as office workers so that their reports, presentations or reports are securely fastened and the text is easy to read.

• We install the device on a solid, stable surface. We prepare in advance the material that we will sew, evenly laying the sheets in a pile. Don't forget to purchase or prepare a cover - most often it is made of thin cardboard or clear plastic wrap.
• This item is not mandatory, but it is best not to skip it. Take one or two unwanted sheets and pre-punch to make sure the settings are correct. If the brochure is capable of working with sheets of different formats, then this item becomes mandatory.

• We insert a maximum of 25-28 sheets for perforation. Some models recommend 15 sheets or less. If the volume of the document is larger, then it is necessary to divide it into parts.

• Carefully place the stack in a special niche until it stops. We make sure that the sheets are located evenly, and their edges do not protrude to the side. Don't forget to fix the side holders.
• Press down on the perforation lever. Then you can remove the sheets from the niche. Re-punching the document is not a good idea. Typically, the new holes will already be offset to the side.
• Perforate the cover separately.
• Now it's the turn of the spring, which will hold the sheets together. It can be metal and plastic. We place the spring on a special comb and use the side lever to open it. It remains only to insert the document correctly: first the cover, then the main document and again the cover. The main thing is not to forget anything - otherwise it will be problematic to unclench the spring, and the document itself will lose its aesthetic appearance.
• We turn the lever to its original position and close the spring. The document is ready. Open the brochure tray and remove the waste paper from the perforations.

For a large office and printing house, an electric bookbinder is the optimal solution. In such a device, perforation is carried out not due to mechanical action, but by pressing a key or pedal, which starts an electric drive for punching holes.

Modern models of electro-perforated brochure machines are distinguished by a wide range of options: switchable knives, vertical paper loading, spring compartment, adjustable perforation indent and many others. etc. Using this technique is easier and more convenient. The principle of operation with electric type booklet makers is similar to mechanical models. The main thing is to carefully read the instructions, since each manufacturer can endow its binder with its own design features that affect the perforation and stitching process.

1. Comb
2. Opening hooks
3. Housing
4. Depth adjuster
5. Indent adjuster
6. Niche for perforation
7. Bed
8. Pallet for waste perforation
9. Lever perforation

1. Insert the sheets to be stapled (max. 12 sheets 80 g / m2) straight into the perforation slot (6) using the adjuster (5). Then punch the booklet with the lever (9). This will punch 21 rectangular holes.

2. For the correct coil size, refer to the table on page 12. Place the plastic coil open side up, behind the comb (1).
Retract the lever (9) until the spiral is open enough to insert the perforated sheets into it.

3. Load the sheets to be stapled vertically into the spiral and lower the lever (9) to its original position.

Our service center repairs both mechanical and electronic brochures.

Brochures are complex mechanical devices in which there are many interconnected parts and assemblies. The successful operation of the brochure depends on the precise and well-organized operation of these units.

If the search brought you to this page, then the above does not apply to your brochure and this brochure needs to be repaired.

We repair every Bindstream brochure, from the basic M08 + to the heavyweight Bindstream M28 +. Over time, the mechanisms of any brochure, regardless of its power, become unusable - some parts are erased, some are stretched, some simply break and fail.

Repair of brochures is most often a mechanical bulkhead of the apparatus with bringing all its components in order. Some elements can be simply adjusted, while some need to be changed to branded parts or even produced on the machine on their own.

In case of failure of the electronic part of the brochure, we also carry out work on the restoration and replacement of the main boards of the device, we change the failed spare parts. parts, and in case of high cost of replacement, if possible, we will repair them.

All these works are done by the specialists of our company. We have extensive experience in repairing Bindstream brochures. Our engineers have given a second life to more than a dozen of these devices.

The repair time and the cost of the work depend on the severity of the breakdown of the device, as well as on how it was followed and whether it was monitored at all during operation. To determine the exact time and cost of repairing the brochure, we suggest you diagnose the brochure in our SC.

Our catalog contains some spare parts for brochuresthat often fail - springs and gears. Perhaps this catalog will be of interest to other service centers and those who repair the brochure on their own.

We also manufacture many mechanical parts on our own.

If you are unable to bring your brochure for repair yourself, you can leave a request and we will pick it up on our own.

You can get additional information from the specialists of our service center.

Respectfully yours, specialists of St. Petersburg-90 LLC

We repair Bindstream, Bulros, Comix, DSB, Fellowes, GBC, Ginny, Hopu, OMA, Renz and other brands of binding machines (brochures) and pickers, including the most recent ones on the market.

You do not have to bring your device to our workshop, our master will be able to travel to any area of ​​Moscow and diagnose the device and make repairs. It is extremely rare, but there are times when it is very difficult to carry out repairs on site. In this case, the repair of the booklet maker is carried out in a stationary workshop.

Prevention includes cleaning all cutting units of the device.Also, preventive maintenance includes cleaning and lubricating the movable mechanisms of the booklet maker.

We would like to draw your attention to the frequent refusals to repair brochurers due to the inexpediency of repairing individual (cheap) models, mainly with a manual drive. Failure to follow the user's instructions for such brochurers, as a rule, entails the replacement of parts that either simply cannot be obtained, or the cost of repairs will exceed 70-80% of the cost of the brochurer itself.

The cost of diagnostics is 300 rubles.

The average cost of repairing a brochure is from 1,500 rubles

Mosservice LLC specializes in the repair of office equipment in Moscow. It's hard to believe, but in 2000, when our company was founded, the staff consisted of only 3 people.

Today "Mosservice" is a modern technical center that provides professional services for the repair of office and household appliances, which is confirmed by the relevant certificates.

Plastic spring binding machines are designed to give documents a presentable look. You can quickly get a beautifully designed catalog, brochure, instruction, abstract or any other document. The technology of binding on a plastic spring allows you to remove or add sheets to finished products.

Let's take a closer look at how the process of binding on a plastic spring looks like. Place the bookbinder on a flat surface. Prepare the document you want to bind (the document itself + front transparent and cardboard back covers).

First you need to perforate the sheets - make holes for the binding.

The front and back covers must also be perforated.

Since you roughly know the number of sheets that are going to bind, you can choose a plastic spring of the required diameter using this table.

Then slide the spring onto the metal comb

and you need to open (unclench) it.

Next, sequentially put the springs on the teeth at the beginning of the cover, then all the sheets, then the second cover, and close the spring.

There are two types of bookbinding machines: with one handle, with its help and pierce and open (close) the spring and with two separate handles for perforation and for opening (closing) the spring. And so, if your typewriter has one handle. Take the recommended number of perforated sheets from the prepared document. Align the edges of the document. Adjust the perforation depth adjuster (the more sheets there are in the document, the greater the margin from the edge). To make sure the setting is correct, make a test punch. Next, place the sheets in the perforation slot, lower the perforation handle and return to its original position. Take out the sheets. And so you perforate the entire document. Next, take a plastic spring. Put on a metal comb. Open the spring and put the perforated sheets on it. When the entire document is on the spring, close it by returning the perforation / spring release knob to its original position. Remove the finished bound document. If you have two separate handles for perforating and opening (closing) the spring on your bookbinder, do everything the same way, only you can open the spring initially and, as the sheets are perforated, immediately put them on the spring (two handles are more convenient).

We examined binding machines (brochures) - mechanical. There are also electric cars. On them, the principle of operation is the same, only electric perforation - by pressing a button or a foot pedal. Very convenient, no effort required.

Our company offers a wide selection of flying machines, as well as everything necessary for binding: plastic springs and covers in color, size, thickness and diameter. We will select for every taste. Plastic springs are resilient and hold the sheets tightly. Documents with such binding are easy to read and convenient to store.

There was a time when specialized organizations were involved in stitching. And there weren't many of them.And the equipment itself was bulky and expensive. But time does not stand still, and now almost any office has its own stitching machine, and any ordinary employee can easily bind an album with documents, drawings, price lists or instructions.

It just so happened that a little more than two years ago, due to industrial necessity, not a typical resident of the house settled in my apartment, namely, a booklet maker. I will not go into details, why and why, but just talk about the advantages of this device.

The booklet maker came to me in an attractive cardboard box, which was packed with foam.

Just do not think that I keep all the boxes from any equipment at home to this day :) It's just that the box is very durable and convenient, so now banks in the garage live in it :)

The stitching machine, despite such a loud name, looks very small and pretty.

The booklet maker is intended for binding documents and other printed materials of A4 and lower format on a plastic spring. The binding on a plastic spring is convenient because in the finished album, if necessary, you can change, remove or add sheets.

Despite its relatively small size, the booklet maker has an average productivity. Punches up to 12 sheets at a time and binds up to 400 sheets at a time. What information can be seen on the case.

Apparently, especially for those users who read the instructions only in the event of a breakdown of equipment :)

Rubber feet and heavy metal base make it stable when working.

The lever with a comfortable handle performs two functions: by moving it in one direction, it pierces the sheets, and when moving to the other side, it opens and closes the spring.

By the way, the lever can be easily removed with a special nut and placed in a horizontal position to save space when the booklet maker is not in use. For example, so that the lever does not interfere with placing the booklet maker on a low shelf.

The schematic representation of the holes on the base allows you to correctly position the sheets in relation to future punctures and in relation to the format.

By the way, the perforation depth can also be adjusted. For this there is a special lever on the side of the booklet maker.

Also, the booklet maker is equipped with a removable bar to support the bound sheets.

and has a drawer for waste.

About pleasant surprises. If you pull out the waste drawer, you can see a cheat sheet for choosing a spring, based on the calculation of the number and volume of sheets

A kind of hint for those who are too lazy to read this and other useful information in the operation manual

In general, to be honest, using this booklet maker, you don't even need to open the instruction manual. All the main points are indicated on the case and are understandable even to a completely inexperienced user.

Summarizing all of the above, I want to briefly note the following pros and cons:

+ Ergonomic removable arm

+ Informational cheat sheets on the case

+ Swing-out metal stand for supporting sheets to be bound

Cons - yes, he has no minuses! An excellent and reliable device for non-industrial binding.

Of course, I think it hardly makes sense to buy it for the binding of term papers or a selection of culinary recipes ... But for creative people who create their projects, portfolios, sketchbooks, this brochure maker can be a good helper. Quickly create an album, replace some sheets if necessary ... What else do you need?

In conclusion, I would like to say that the booklet maker is quite ergonomic, very simple and intuitive to use, and does not take up much space. Modern and discreet design allows it to be harmoniously combined with any office equipment. Perfect for small offices and small binding volumes.

I recommend for purchase to everyone who needs this device.

Bookletters, like other equipment, are prone to various breakdowns that occur both during the production process (use of low-quality materials) and through the fault of the user (careless handling). Whatever the reason repair of booklet makers must be produced only in specialized centers.

The opinion that it does not matter at all where the booklet maker is repaired, in a specialized center or in a “market” workshop, is erroneous, because the entire further operation of the device depends on the quality of the repair.

The main reasons why it is necessary to produce bookbinder repair only in professional centers:

• Qualified specialists;
• Extensive work experience;
• Modern technical base;
• Use of quality spare parts;
• Guarantee for all types of work.

When the equipment involved in production starts to junk or simply breaks down, this affects the entire activity of the organization and slows down the process of creating a particular product. Therefore, if at first glance, even insignificant signals appear that the booklet maker may soon fail, you should contact the Master Plus Repair Center for help.

We make diagnostics and repair of binders (booklet makers), copiers, laminators and many other devices, regardless of the model. Qualified specialists of our center will quickly restore the functionality of any electronics and small household appliances.

There are more and more various electronic assistants in our kitchen, and more and more they fail, especially if you save money and buy the cheapest ones. Of course, expensive blender models are not immune to burnout, but according to statistics, this happens less often. So, blender. It can be submersible manual or tabletop. The essence of this does not change much - in both cases we have a rotating attachment (knives, whisk), which is driven by an electric motor located in a molded plastic or metal body of the blender. Control ranges from simple on / off to multiple electronically controlled speeds. To visualize all this - take a look at the blender diagram:

1. Container jug
2. Latch
3. Cutter
4. Spindle
5. Drive shaft
6. Electric motor
7. Locking mechanism
8. Switch
9. Cord

The immersion blender is not too different, and as for possible problems, they are almost the same and boil down to a broken cord, burning contacts, burning an electronic speed controller or an electric motor.

Practice shows that it is the motor that is the weakest link. Typical case: blender Orion ORB-012 stopped spinning after they stubbornly tried to grind frozen berries, despite slipping and jamming. In very many models, the engine can fail if it runs for more than a certain period.

Disassembling this device is difficult for a layman, not everyone will guess that it is necessary to start with the speed regulator cap.

We pry it with a screwdriver and remove it from the rod, and under it are 4 screws that secure the top cover, which in turn closes the board with the details.

Next, you need to pull out the plastic sleeve near the attachment of the nozzle, which covers the electric motor. Only by pulling out the motor can you pull out the speed controller board after it.

A burnt out motor can be immediately understood by the strong smell of burning. Here, medicine is already powerless, there is no point in rewinding the windings, because it will cost more than buying a new blender.

If the motor is still alive, we look at the regulator. It is assembled according to the circuit of a triac phase regulator, which has approximately the following circuit:

As you can see from the diagram and from the photographs, there are two buttons on the body. One connects the motor immediately to maximum speed, supplying a large voltage, and the other turns on the motor through the speed regulator. There is a noise filter at the input of the 220v network, so that when the blender is on, you do not have interference on the radio and TV.

Pay attention to the fuse. If you are lucky, it will be burnt out, and the independent repair of the blender will successfully end there, under the thunderous applause of the mother or wife 🙂 If not, check the correct connection of the plug, the integrity of the cord, the contact of the buttons, the details of the circuit.

Nowadays, more and more people are forced to do their work and business within the walls of their homes. Many liberal professions have appeared that do not require a constant presence in offices, people have the opportunity to choose a job that is profitable for themselves, the timing of the work and the amount of money for which they agree to do this work. This is, of course, a big plus. But the success of such activities requires considerable investment in equipping your workplace at home.

It so happened that some of my work had to be done at home, but now I work completely for myself and naturally I had to equip a normal workplace in the apartment, purchase a scanner, a powerful printer and other technical gadgets for work. One of the most useful acquisitions for me was the purchase of the Profi Office Bindstream M12 saddle stitching machine. This machine is designed for binding documents with plastic springs.

The model of this booklet maker is compact and very easy to use. It can bind up to 200 A-4 pages. It is easy to make brochures, catalogs, generate reports at home. With his purchase, all the paper chaos was sorted out from me. Probably, many are familiar with such a situation when a heap of important papers accumulates and each time it is more and more difficult to find the necessary document among this heap. So now all my notes, lectures, project materials are sorted out and formed into catalogs. Well, and the most important moment for me, I present my work to customers in a very decent way. I form explanations for projects into booklets, cover pages on a computer, select covers in accordance with the purpose of the document. All this gives solidity to documents and it is pleasant to give such work to clients.

Dimensions of the Profi Office Bindstream M12 booklet maker - 230х380х410. The box with it takes up very little space. One lever is used for punching and binding with a spring. The principle of operation of this machine: first, we make holes in the sheet with a puncher, and then we install the spring, open it with a lever, insert the prepared sheets and close the spring.

The springs for this model are plastic. The diameter is selected depending on the number of sheets. You can use very small ones up to 10 sheets and large ones up to 200 sheets. Springs are available in a variety of colors and diameters. Sold in boxes of 100.

Using colored springs and different covers, it is easy to create interesting design brochures or catalogs, the scope for creativity in this case is not limited. Of course, this booklet maker is not comparable to powerful electric bookbinding machines, but for home use, it is a great machine.

Bookbinding machines are used to make documents presentable. In fact, each of us has held a similar product at least once, but not everyone knows how to use a booklet maker.

When buying a bookbinder from any manufacturer, the kit necessarily includes instructions for using the booklet maker. It describes in detail all the actions that are necessary to obtain the optimal result.

To bind an abstract, diploma, catalog or any other documentation, you must:

Insert the sheets required for stapling straight into the perforation niche, guided by the adjuster. Next, punch the booklet with the lever. This will punch holes.

Having decided on the size of the spiral, place the plastic or metal spiral with the open side up, behind the comb. Then it is necessary to retract the lever until the spiral is open enough to put the sheets to be sewn into it.

Insert vertically perforated sheets into the spiral and lower the lever to its original position.

Remove the stitched brochure from the comb.The brochure is ready.

At the moment, there are two types of flying machines on sale, mechanical and electrical. However, the sequence of actions does not change. Only in an electric device, perforation is carried out by pressing a foot pedal or a special button.

A blender is a multifunctional home appliance that is found in almost every kitchen. This is a convenient device that can replace several devices at once. With its help, grind, mix, beat the products. The design of blenders is simple, so they are quite reliable, but even the most reliable technique fails. Consider how to disassemble a submersible and stationary blender, find the cause of the breakdown and do it yourself repairs.

All blenders can be divided into two types - stationary (tabletop) and submersible (hand-held). They differ in design and method of operation, may have different attachments and additional functions. To repair a stationary or hand blender, you need to understand the features of its device.

The hand-held models are long-handled electrical appliances with a cutting attachment. They are dipped into a bowl with products that need to be chopped and mixed, pressed on the start button and held until the procedure is over.

The undoubted advantages of submersible models include compactness. The devices are easy to disassemble for cleaning, plus they need a minimum of space to store them. Blenders with a large number of attachments are versatile and perform a variety of food preparation operations.

There is only one drawback of submersible structures, but it is significant. During cooking, you have to hold the device in your hand while pressing the start button. If you have to do this within 1-2 minutes, the hand gets tired, numb. Such a device is not suitable for frequent use, because does not cope well with mixing large portions of food.

Making Soup with a Hand Blender

Stationary models resemble food processors in appearance and often perform many functions. They are bowls with rotating knives attached to the bottom. Such a device is installed on a table, you do not have to hold it with your hands while working. He is able to grind a large portion of food at a time, copes with mixing cocktails, liquid dough.

Desktop models also have drawbacks. The hostess has to allocate quite a lot of storage and installation space. In addition, some stationary blenders do not grind vegetables well: they either grind into crumbs or remain large chunks. The advantages of tabletop structures include the fact that they are sometimes easier to disassemble and repair with your own hands than submersible ones.

Although the principles of operation of submersible and stationary blenders are similar, there are still differences due to the different design of the devices. In all models, products are chopped with knives, but in tabletop appliances, the bowls also serve as an auxiliary function.

The knife of the stationary appliance, located at the bottom of the bowl, rotates and cuts the food. With an increase in speed, the crushed mass is mixed, rises up. The walls of the bowl expand upward, so small pieces slide along the walls, and large pieces fall into the center - to the knives. It turns out that the crosspiece pulls down the pieces of food and throws the already crushed mass to the walls of the bowl.

It is not uncommon for a blender to be considered broken if it does a poor job of chopping. But it happens that the problem is not in breakdowns, but in the low power of the electric motor. Sometimes it is enough to add a little liquid to the bowl to make the work of the knives easier.

If the model is powerful, then such deviations in operation can really indicate malfunctions, for example, a blunt knife, a broken speed switch, etc. In some cases, problems with the bowl may be the cause of poor performance.

Stationary model device

In submersible structures, collector-type electric motors and fuses are usually installed that turn off the device in case of overload.Frequent breakdown - burning of current-carrying parts, therefore, when a malfunction occurs, first of all, the contacts "ring out" by rotating the shaft by hand.

Care must be taken when using handheld devices: they are not suitable for kneading dough and other thick products. The motor may not be able to withstand the load. Repairs will be expensive. However, there is good news: often women's hands get tired of holding the equipment before the engine has time to overheat.

Many models are equipped with gear shifters. This is a very convenient feature that expands the capabilities of the hostess. But if the engine does not cope, then the working device can break out of the hands, which becomes the cause of mechanical failure.

Submersible model device

In submersible models, the power cable is often damaged. This is the flip side of the main advantage of such devices - mobility. The hand blender is often turned on and off, carried from place to place, which leads to kinks in the cord, incl. critical.

Unstable operation of the power grid is also a risk factor. During power surges, motors often burn, printed circuit boards are destroyed. Often it is necessary to replace the knife, repair the attachment, the speed regulator. In table-top appliances, liquid may leak into the nozzle drive, the bowl snap mechanism may break.

Hand blender repair

Consider how to check the performance of individual structural units:

• If the blender does not turn on, the first thing to check is the presence of current in the electrical outlet. Before disassembling the device for repair, you need to make sure that there are no power problems. The outlet is checked using a tester or by connecting to it another electrical appliance, which has an accurately working cord.

• If there is current, but the blender does not turn on, check the power cable and fuse. Repair in this case comes down to replacing faulty parts with new ones.

• Overloads can burn the motor. In addition to problems with performance, such a breakdown gives off a burning smell. Sometimes the device can be repaired by replacing the brushes on your own, but more often you have to give the blender to a service center for repair or buy a new one.

• When the elements of the printed circuit board burn out, a short circuit occurs. It is necessary to disassemble the equipment, inspect the board, test and, if necessary, re-solder the faulty elements.

• If the gasket leaks, then it must be replaced with a new one. liquid can get on the electric motor and cause more serious repairs.

Diagnostics of malfunctions of the submersible model

Housewives are often faced with a situation where the blender has stopped and the knife is not spinning. It happens that the knife is spinning, the engine and the speed switch are in good order, but when loading the products, the device runs “idle” without grinding them. In many cases, repairs can be done by hand. Let's figure out how to do this.

Stationary blender device diagram

(KMU: make a screenshot of the 1st picture with the name of the parts)

Before disassembling the blender for repair, you should carefully read the technical documentation. Disassembly instructions may be supplied with Bosch, Philips, Scarlett, Polaris models. It is best to follow the manufacturer's recommendations. Otherwise, there is a high risk of permanently breaking the device.

For disassembly and repair, you will need the following tools:

• flat thin screwdriver (if such a screwdriver is not available, it can be replaced with a narrow knife);
• long screwdriver;
• pliers;
• a magnet to reach small parts if you cannot remove them with tools;
• superglue or any other reliable adhesive with which you can restore the integrity of the seams if they are damaged.

DIY blender disassembly procedure:

1. Remove all screws, remembering or noting where they are located.
2. Remove as many items as possible.

Note! Some craftsmen offer a more radical option for disassembly: a narrow screwdriver or knife is pushed between the body and the casing of the device and the weld is knocked down with an accurate hammer blow. This method is only suitable for non-collapsible models, and superglue is required to reassemble them after repair.

1. Parts that could not be removed must be carefully inspected. They can be clipped. In this case, they can be removed by pressing the latches.
2. When the case is disassembled, you can start checking the performance of parts and repairing.

The most common models of Scarlett ("Scarlet"), Vitek ("Vitek"), Polaris ("Polaris"), Philips ("Philips"), Bosch ("Bosch") are usually disassembled, so they can be repaired by hand, replaced nozzles. Let's consider in what cases self-repair is possible.

1. Replacing the knife. If the knife is dull, it can only be replaced, because it cannot be sharpened. New knives are sold in specialized and hardware stores. To replace, remove the old part by wrapping a towel around it and unscrewing it. After that, insert a new knife (it may differ in appearance from the old one), secure.

Important! Sometimes you can buy a new knife complete with an oil seal. It makes sense to replace both parts at once. In some stationary models, the knife cannot be removed from the bowl, because it is not collapsible. Then there remains only the option of a complex replacement of the bowl, knife and gland.

Old and new knives

1. Speed ​​regulator. In stationary models, it may be difficult to check the switch, because the function of blocking switching on without a bowl is often provided. By the way, the problem of stopping the operation of the device is also associated with blocking. If you suspect a malfunction of the speed switch, it must be evaporated, each position must be checked in full, and repaired.

1. Stopping work. If the device does not turn on, the first thing to do is check and, if necessary, replace the cord. If it turns on and buzzes, but does not work, then disable the lock. Inoperability when the blocking is released most often indicates a burnout of the electric motor winding. It can be replaced, but this is an expensive repair, so more often than not it is more profitable to just buy a new blender.

Note! The problem might be with the circuit boards. Capacitors and resistors are worth inspecting. If a short circuit occurs, then it is better to give the device to specialists. In many cases, damaged electronics cannot be repaired or the cost is too high.
