Electric razor repair using inexpensive batteries. Electric razor repair tips How to disassemble a Brown 5 series electric razor

Even though thick, well-groomed beards are now in fashion, a clean-shaven man has always attracted women. What helps you be so clean-shaven? — Electric razor. They are wonderful in every way, except that they break, and it is quite possible to repair a Brown electric razor with your own hands, if only you have the desire. And it should arise, because it is not at all a fact that instead of a device that is ideal in all respects, you will receive a new one, but not so convenient. We will tell you exactly how to repair an electric razor in this article.

Cleaning the shaver head

As you know, all modern electric shavers are divided into 2 main classes:

• Mesh;
• Rotary.

Rotary knives are so named because the knives rotate like a rotor. Before we consider repairing an electric razor ourselves, we will describe the cleaning process. Perhaps you won’t have to repair anything, you just need timely care of the device parts.

In most cases, when the device stops fighting the beard, this means that the head is clogged. Quite often, the electric razor comes with a brush and a special aerosol. It's time to find out why these items are needed.

Cleaning a rotary electric razor

Roughly speaking, the head of an electric razor lasts no more than one year. After this period, it is considered time to change it. And of course, once every 3 weeks it is recommended to remove dirt from this block. If we are talking about a rotary electric shaver, start with the outer foils:

1. Carefully but gently pass the brush around each of the meshes, sweeping out any hair clippings.
2. After this, unfasten the blade block from the body of your electric razor. Typically, this module is disassembled into its component parts.
3. Remove the holder with knives and nets from the plastic frame.

Pairs of cutting surfaces are also divided into two parts. After disassembly, you should have on your table:

• plastic frame;
• holder;
• rotary knife.

Each knife has a flange bushing shape. This is a piece of thick-walled pipe, at the end of which there is a washer three times larger in diameter. On the appeared platform with a hole in a circle in the middle, there are beveled protrusions along with cutting surfaces.

Important! Be extremely careful, even when dull, electric razor knives can cause harm to human health. By the way, the same applies to grid models. That is why you should handle knives with extreme care.

Everyone saw the net. They are round parts with small holes in a circle that slide during shaving:

1. Use a brush to sweep each part of the shaver head. If the razor comes with an aerosol, then spray the foils and knives with the aerosol and clean again.
2. Now put all the elements together and install them back.
3. A slight click means that the electric razor is completely ready for shaving.
4. Be sure to check the mechanism after assembly. It may well happen that the parts are assembled incorrectly, or the knife block is crooked.
5. In this case, disassemble the electric razor following the above recommendations.

If this doesn't help, then it's time for you to buy a new head.

Cleaning your foil electric shaver

Do not rush to take up the brush, as in the previous case. You can't do this. Even gentle touches can damage the original shape of the mesh. In this case, not only will the electric razor work worse, it is quite possible that the knives will be blocked.

Instead of trying to clean the razor:

• Find a disinfectant spray and spray the blades with it before washing. Of course, this tool must be intended for these purposes.
• Also try to keep the knives under ultraviolet rays (lamp) in order to block the growth of bacteria.

Rotary electric shavers

To find out which part of the electric razor needs repair, we proceed step by step.

Engine

The internal mechanism of a rotary electric razor is quite simple:

• Inside there is a motor that, using an output shaft and an eccentric gear, transmits torque to two or three knives. Everything on the outside is protected by a plastic casing.
• In order to filter the instability of the supply voltage, there are several chokes and capacitors inside.
• Electric shavers that are designed for use with a variety of voltages must have a special switch. To implement the technical capabilities of operating from various networks, the stator coil has four windings. As a rule, their wires have their own fixed color.

Knives

Before you disassemble the electric razor yourself, try to turn it on without the blades. In the event that there is no automatic blocking when the head is absent, the drive must rotate. If this happens, then the problem is in the head. Remove it, disassemble it and inspect it.

Important! In this case, it is possible that the electric razor assembly hums, but the knives themselves do not rotate.

Nutrition

The next step is to check the electrical voltage. If everything is in order with the network, disconnect the wire together with the block from the case and measure the voltage on it by connecting it to the socket.

Important! Be extremely careful to avoid electric shock.

You can check the cord by testing it with a multimeter. If the signal is quite erratic, you may be dealing with a floating cliff. In this case, try to supply power to the electric razor through a different wire. If everything is in order, then the problem itself was directly in the wire.

Even razor enthusiasts can use an electric razor on a business trip or vacation. The ability to instantly shave in almost any conditions makes electric razors truly convenient and very practical. Modern electric shavers work extremely reliably if you clean them regularly and replace the blades at the first sign of the need for such replacement.

How does it work

Electric shavers are either mains powered (in which case they have a coiled cord with a two-prong plug) or powered by dry cell batteries or rechargeable batteries.

Mains-powered electric shavers are plugged into special sockets for electric shavers approved for installation in bathrooms, as they contain a transformer that isolates the consumer part of the device from mains voltage and reduces the risk of electric shock. This type of electric shavers usually has a voltage switch: 210-230 volts for Europe and 110-130 volts for the US. Some models are made with automatic adjustment to the mains voltage.

Foil type electric shavers

Foil shavers (the most common type) have a standard cutter head consisting of a flexible metal mesh that covers a blade, or knife, block on a clip or simply a knife that makes a rapid back-and-forth motion. This oscillatory motion is created using an electric vibrator consisting of two solenoid coils, which together with two springs move the holder with the knife block from side to side.

In some foil electric shavers, the oscillatory motion is provided by a conventional rotary electric motor connected to the blade block using a crank mechanism.

Rotary electric shavers

A rotary electric shaver has multiple cutter heads, each of which consists of a rapidly rotating rotary blade located under a mesh disc. Since knives cannot be sharpened, they have to be replaced when they become dull. Such razors are usually driven by rotary electric motors connected to the knives through a gearbox and drive shafts.

Doesn't shave well

The cutter head is clogged

If cutter heads are not cleaned regularly, their performance will quickly deteriorate. Some electric shavers can be washed under running water, but since most models cannot be wetted, you should check the instructions.

1. After each shave, turn off the razor and unplug it from the socket, then press the appropriate buttons to remove the cutter head.
2. Tap the back of the head on a flat surface to dislodge the cut hairs. The mesh is so thin that brushing can damage it - check the instructions.
3. Use the soft brush included with the razor to clean the blade unit.

1. Some manufacturers provide the razor with an aerosol cleaner, which is applied to the cutter head once a month before brushing.
2. If you have very dry skin, apply special shaving oil to your skin. As an alternative, you can lubricate the foil with a drop of the same product for a softer shave.

To clean your rotary shaver, unplug it and lightly brush the cutter heads to remove any bits of hair. Then remove the entire cutter head assembly and clean the inside.

Every week, open the pressure pad, remove the mesh discs and rotary blades and clean them separately. For best results, do not bunch the mesh discs and knives together.

Dull knives

All razors should give a good shave for about a year, and then you need to change the knives - however, if you previously felt that the knives were dull, then you should change them.

The blade block of a foil electric razor can be removed entirely. In some models it simply rises up, in others it must first be rotated 90°. Look in the instructions. Be careful - even when dull, knives can cut.

Rice. 12 Replace a dull blade block

If the rotary cutter heads are dull, replace them all at once.

Damaged mesh

Visually, you can notice torn or cracked areas on the shaving foil. The damage could also dull the blades of the knife block, so you will probably have to replace it at the same time. When replacing, be careful not to damage the mesh.

Noisy operation

The head is clogged

Remove the cutter head and brush with a brush, moving it across the cutter block to clean the spaces between them. Replace the head and lubricate the foil with proprietary shaving oil.

The mesh is damaged

Do not move the blades over a damaged mesh or mesh disk; replace both parts.

Rice. 13 Check the mesh for damage

WORKS SLOWLY

If the razor does not shave well after replacing the blade block or cutter head, check that the parts are installed correctly.

THE RAZOR IS HEATING

Cord contacts

If the contacts inside the cord tip show signs of being burned, purchase and replace the cord before the razor fails completely.

Rice. 14 Check the cord contacts

Faulty motor or battery

Check your electric razor at a service center.

NOT WORKING AT ALL

Incorrect voltage

Check that the power supply voltage on the shaver is set correctly.

Knives jammed

Remove the cutter head and check whether the motor operates normally. If so, the cutter head may have become stuck. Check the condition of the inner surface of the screen or screen disk and if damaged, replace the entire head.

Faulty cord or plug

Check the condition of the cord with a tester (Fig. 15) by touching the contact pin of the plug with one probe and the contacts at the other end of the cord with the other. By touching one at a time, you will determine the presence of a break.

Rice. 15 Checking the condition of the cord with a tester

To ensure that there is no intermittent damage, hold the tester's probes on the cord contacts and have someone gently bend and unbend the cord at various points along its length. If you suspect a break, replace the cord.

Faulty switch

Have the switch checked by a service workshop.

The charger does not work

If you can get the same charger somewhere, you can check if your razor holds a charge. Or have it checked at a service center.

Motor failure

For both types of razors, the electric motor can only be repaired by a qualified specialist.

THE MAIN THING IS SAFETY

1. Be sure to unplug the shaver before cleaning or changing cutter heads.
2. Do not wet your electric razor unless it is designed to be rinsed under running water; check the instructions.
3. Do not open the body of a waterproof electric razor.
4. Do not throw away rechargeable batteries with normal waste and never throw them into fire. Take failed batteries to an electric razor service center or throw them away in a specially designated place (municipal authorities should tell you where the nearest one is located).

Good luck with the renovation!

All men are divided into two groups: those who shave with disposable razors, and those who use electric shavers. The first ones don’t have any problems with the tool: if it gets dull, throw it away. But a good electric razor costs a lot of money, so if it breaks, it makes sense to carry out repairs yourself.

Electric shavers come with mains power from an outlet and with a built-in battery. Moreover, most often we come across models of the second type. Inside they contain a power button, a charger, a battery and a motor (electromagnet) with shaving blades.

Since knives cannot be sharpened, they have to be replaced when they become dull. Such razors are usually driven by electric motors connected to the knives through a gearbox.

To replace the blades in the shaving head, you need to remove the protective cap from the blade unit of the electric razor. Remove the blade unit of the electric razor from the base. Replace the knives in the knife block.

Shaver electronics repair

Let's look at the repair of electronic components, using the example of the little-known Chinese Toshiko razor. If the razor fails to operate, first check the integrity of the power cord. It may be broken internally, for example near the power plug.

The next weak link is the power button. To check it, simply close the contacts with a screwdriver and see if the electric motor starts working.

In this case, the problem seemed to be in the 220V voltage converter that charges the battery. As you can see in the photo, the transistor burned out and cracked.

After the replacement, a new problem was discovered - the battery almost did not hold a charge.

There is a 1.2 volt 600mA nickel-cadmium battery installed here, so finding a similar one is not a problem - we just buy a new one in the store.

An electric razor is a device of small household appliances for shaving, which consists of a special cutting mechanism with mesh knives connected to an electric drive powered by a household electrical network or battery, as well as a plastic case. The knife of an electric razor consists of two parts - movable and fixed.

Schematic of the PHILIPS HQ 5890 razor

Three floating heads of the HQ5 razor with rotating blades and a compact electric motor (EM) create a fairly low noise level and guarantee an almost silent shave without vibration. The razor operates from a standard household network or from a rechargeable battery located in the body of the electric razor. Only environmentally friendly nickel-metal hydride batteries of medium capacity are used.

Charging the battery for an hour allows you to shave for about three weeks without connecting to the mains.

Power selection is carried out automatically. In addition, PHILIPS HQ 5890 has special characteristics that increase the comfort of the razor: indication of the remaining shaving time; electronic signal about the need for cleaning; sound warning signal about low battery; indication of complete discharge and charging of the battery; the presence of a wall holder for hanging the razor. The round razor blades provide an optimal shave in any direction. The slots in the fixed blades are safe and reliably guide even long hair into the cutting unit.

Self-sharpening razor knives remain sharp even after many years of use. And finally, another important convenience - the shaved hair remains inside the razor. The "Reflex Action" shaving system, which is based on a unique system of rotary action knives, creates maximum convenience. Thus, for a more thorough and comfortable shave, the razor heads follow the contours of the face.

The "Lift & Cut" system used in PHILIPS razors lifts the hair before cutting it. For sensitive skin, there are 9 convenient settings for the height of contact between the movable knives and the fixed ones.

After removing the shaving unit 4, you need to unscrew the three screws in the lower part of the plastic housing 11 and remove it. Then you will need to remove the cutting block 8 and separate the base of the plastic case 5 from the frame 3, removing the two screws holding them together. Next, remove the three gear wheels 6 and the link 7. Unscrew two more screws securing the ED 10, disconnect the voltage switch block 1 and switch 2. And finally, remove the ninth lever.

So, what problems can the owner expect? The most obvious one is that when plugged in, the razor simply does not work. Of course, first of all you should check the power cord - with an ohmmeter or a probe, and then make sure that the switch is working properly by testing its contacts with a device. A slightly more complicated procedure awaits if the razor hums when turned on, but the engine armature does not budge. Then you need to check how easily the armature rotates. Remove the tendrils of the brush holder springs, releasing their pressure on the brushes, and with a sharp movement, unwind the armature through the drive gear. If the armature is difficult to rotate, you need to loosen the two screws holding the brush assembly block to the board and lubricate both armature bearings.

Well, if this does not help, it is likely that the winding is broken and the razor will still have to be taken to the workshop. This problem cannot be fixed at home. Interruptions in the operation of the razor can also occur because the brushes get stuck in the brush holders. This is not difficult to check. Turn on the razor and use an insulated screwdriver to gently press down on the brushes. If the razor starts working, the cause of the defect may be that grease has gotten on the brushes or the springs do not press them enough.

Take out the brushes and heat them one by one with a soldering iron, the oil will burn off, then sand them with fine sandpaper or a file so that they fit easily into the brush holders. At the same time, check the length of the brushes and if they are worn out by more than half, replace the brushes.

Wipe the surface of the collector with a cloth moistened with alcohol or cologne. The next reason for dissatisfaction with an electric razor is poor shaving quality. It is clear that fixed knives with worn surfaces simply need to be replaced. But it happens that the moving knives do not fit well with the stationary ones. Then you should place one or two washers under the gear wheel, the driver of which presses the knife. Owners of electric shavers should know that once every six months it is necessary to clean the motor armature commutator and fill the oil seals with new lubricant. To do this, unscrew the mounting screws and remove the electric motor from the razor body. Remove the gears. Use fine sandpaper to clean the collector plates, and use the tip of a knife to carefully clean the grooves between the plates. Then blow off the coal dust.

First, introduce two or three drops of MVP or MP-704 oil into the upper oil seal, and then into the lower one (Fig. 2). Lubricate carefully, making sure that no oil gets on the carbon brushes.

When collecting a cleaned and lubricated razor, be careful. Install rubber and metal washers correctly. If the carbon brushes become worn, they should be replaced. Before installing the brushes in their places, make grooves in them so that the brush holder spring cannot jump out of its intended place. The carbon brush should fit into the brush holder completely freely, without effort. If the brush is large, it should be sharpened with a personal file or emery cloth.

To carry out minor preventative repairs on an electric razor, it must be disassembled. Disassembly can be either partial or complete. The procedure for dismantling razor parts may vary significantly depending on the manufacturer and the specific model of the device. In any case, it is not recommended to completely disassemble the device if the warranty period for the electric razor has not expired.

You will need

• - screwdriver;
• - knife.

Instructions

To dismantle a razor with a commutator motor, remove the protective cap and blade block. Remove the cover (hair catcher). Press out the blade block holders and remove the razor blades.

Unscrew the fastening screws and remove one of the housing halves. Slide the shaver body along the cord towards the plug. Now unscrew the screws securing the connecting cord strip. If repairs are necessary, unsolder the cord. If the purpose of disassembly is to repair the electric motor, disconnect it by unscrewing the fasteners, remove the washers and rubber gaskets.

To replace the body of the electric razor, disassemble the device, unscrew the screw securing the body halves and move the bracket. Disconnect the screen from the stator, move the screen and varnish cloth to the side. Remove the cord. After repair, thread the cord into the hole in the new case and solder it, following the wiring diagram.

Sometimes disassembly is carried out to replace the leash. In this case, in addition to general disassembly, unscrew the two set screws securing the driver and remove the lock nuts. Place a new leash on the eccentric, then push the mechanism all the way down.

When replacing brushes after standard disassembly, unscrew the screws securing the brush holder and remove them. Disconnect the spring and brush from the brush holder.

When dismantling a shaver with a built-in electromagnetic vibrator, first remove the protective cap. Press the holder and remove the blade unit. Unscrew the screws and remove the device housing cover. Remove the contact block, mains switch and voltage switch from the housing grooves. Remove the cap, washers, bridge and vibrator armature springs. Disconnect the stator with field coils.

As a rule, disassembling an electric razor is performed for preventive maintenance or replacement of faulty parts. Strive to ensure that unless absolutely necessary, do not dismantle parts that do not require maintenance or repair. After dismantling the device, reassemble it in the reverse order. Pay special attention to the reliability of fastening the parts.
