The three floating heads of the HQ5 with rotating blades and a compact electric motor (EM) create a fairly low noise level and guarantee a virtually silent shave without generating vibrations. The shaver operates from a standard household network or from a rechargeable battery located in the shaver body. Use only environmentally friendly, medium-capacity nickel-metal hydride batteries.

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

Power selection is carried out automatically. In addition, PHILIPS HQ 5890 has special features that increase the comfort of the shaver: indication of the remaining shaving time; electronic signal about the need for cleaning; sound signal for warning about battery discharge; indication of complete discharge and charging of the storage battery; the presence of a wall holder for hanging the razor. The circular razor blades provide optimal shaving in any direction. The slits in the fixed knives are safe and securely guide even long hair into the cutter block.

Self-sharpening razor blades stay sharp even after many years of use. And, finally, one more important convenience - shaved hair remains inside the shaving device. The "Reflex Action" shaving system, which is based on a unique rotary blade system, creates maximum comfort. So, for a more thorough and comfortable shave, the shaving heads follow the contours of your face.

The PHILIPS "Lift & Cut" system lifts hair before cutting. For sensitive skin, there are 9 convenient settings for the height of the moving knives to the fixed ones.

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

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

Well, if this did not help, it is likely that the winding is broken and the razor will still have to be carried to the workshop. At home, such a malfunction cannot be eliminated. Shaver interruptions can also occur because the brushes get stuck in the brush holders. This is not difficult to verify. Turn on the shaver and use an insulated screwdriver to gently press down on the brushes. If the shaver works, the cause of the defect may be that the brushes have gotten grease or they are not being pressed sufficiently by the springs.

Take out the brushes and heat them one by one with a soldering iron, while the oil will burn out, then grind with a fine sandpaper or a file so that they easily fit 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 collector surface with a cloth dampened with alcohol or cologne. The next reason for dissatisfaction with the electric shaver is poor shaving quality. It is clear that fixed knives with worn surfaces only need to be replaced. But it happens that movable knives do not adhere well to fixed ones. Then you should put one or two washers under the gear wheel, the leash of which presses the knife. Shaver owners should be aware that every six months it is necessary to clean the motor armature manifold and fill the oil seals with new grease. To do this, unscrew the fastening screws and remove the electric motor from the shaver body. Remove the gear wheels. Sand the collector plates with fine emery cloth, and carefully clean the grooves between the plates with the tip of a knife. Then blow off the coal dust.

First, insert 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.

Be careful when picking up a cleaned and oiled razor. Install rubber and metal washers correctly. If the carbon brushes are worn out, they should be replaced. Before installing the brushes in their places, grind grooves in them so that the brush holder spring cannot jump off its intended place. The carbon brush should enter the brush holder completely freely, without effort. If the brush is large, it should be filed with a personal file or emery cloth.

The electric shaver (Fig. 1) features three floating HQS shaving heads with rotating blades and a micromotor for minimal noise and a virtually silent shave without vibration.

The electric shaver is powered by an alternating current (mains voltage is automatically selected) and from a battery built into the shaver body. Environmentally friendly nickel-metal-hydride elements with high energy consumption are used. Charging the battery for one hour allows you to shave for three weeks without being connected to the mains.

Optical indication of charging is applied. This model has special features that make the shaver more comfortable:

  • indication of the remaining time of autonomous shaving;
  • electronic signal of notification of the need for cleaning;
  • sound signal for warning about battery discharge;
  • indication of complete discharge and battery charging;
  • wall holder for hanging the razor.

The round knives shave well in any direction. The slits in the fixed knives guide even long hair safely and reliably into the cutting unit.

Do-it-yourself electric shaver repair is within the power of a master.Soberly assess the existing skills, if you do not see the difference between an inductor and a capacitor, you are afraid to measure the voltage of 230 volts without threatening people's lives, it is better to discard the venture. Everyone can clean the mechanism when the electric razor does not cut. But you boast to your acquaintances: now you know how to repair Mikma electric shavers.

Modern electric shavers form two broad classes:

The first are named for the knives that rotate the rotors of electric motors. Before considering how to repair an electric shaver yourself, we will describe the cleaning process. In most cases, when the device refuses to shape beards, it means that the working head is dirty. The electric shaver set is supplemented with a brush and a special spray. Let's find out the purpose of things.

The shaver head will last no longer than 1 year. After it is considered: it's time to replace. It is recommended to clean the unit every three weeks. In the case of a rotary shaver, start with the outer screens. Gently brush each one around, sweeping out the hair clippings.

After that, the knife block is unfastened from the shaver body. The unit is disassembled into its component parts. The holder with knives and nets is removed from the plastic frame. Each pair of cutting surfaces is divided into two parts. Now the table is littered with:

  1. plastic frame;
  2. holder;
  3. two to three pairs of cutting surfaces, consisting of:
  • rotary knife;
  • mesh.

Each knife is shaped like a flange sleeve. A section of a thick-walled tube, at one end there is a washer two to three times larger in diameter. On the formed platform with a hole in the middle, beveled projections provided with cutting surfaces are located in a circle. Be careful, even when dull, the blades of an electric shaver can be harmful to your health. By the way, it concerns mesh models. Handle knives with care. Everyone saw the grid. Round parts with slits in a circle that glide over the skin as you shave.

We sweep each element of the shaver head with a brush, if an aerosol is supplied in the kit, we process the knives and nets, and we clean again. It remains to put together the nodes by setting back.

A light click means the shaver is ready to use. Check the product after assembly. It may happen that the parts are assembled incorrectly, the knife block is crooked. The shaver does not work, still does not cut - the operation was performed incorrectly.

Disassemble the shaver following the instructions above and reassemble. It didn't help, it's time to buy a new head.

Wait a moment to take the brush. You can't do it. Even a gentle touch of the bristles can damage the correct shape of the mesh. The shaver does not work well and the blades may become blocked. Straightening the mesh at home without harming it is difficult. Electric shaver repair shops will be useless helpers.

First. If the shaver is washable, clean it after each use. Consider one thing. The electric shaver is good after the purchase for the first 3-5 procedures. Then the bacteria begin to multiply in shock in the head, each use brings irritation to the skin, which is powerless to remove with special personal hygiene products. Try to find a disinfectant spray instead, treat the blades before washing. Naturally, the remedy must be for these purposes. Try holding the knives under an ultraviolet light to block the growth of bacteria.

Regarding other types of electric shavers, they are cleaned every few procedures, without the use of water. For this purpose, the mesh is carefully removed. Cleanse from hair residues by blowing properly. Try, after removing the head, knock the end of the table gently. Partially removes dirt from the shaver mesh. The knife block is fanned with a brush. If there is an aerosol in the kit, use for additional cleaning of the device.

Try the recessed foil shaver after assembly in the same way as in the previous case. The effect is unsatisfactory - it's time to buy a new head.

The internal structure of a rotary electric shaver is simple.An engine is mounted inside, by means of an output shaft and an eccentric gear that transmits torque to two or three knives. The outside of the mechanism is protected by a plastic case.

To filter the instability of the supply voltage, there are several chokes and capacitors inside. Electric shavers designed for use with different voltages have a special switch. For the technical implementation of the possibility of operation from different networks, the stator coil has four windings. Copper wires clad with cambric have a fixed color.

Before disassembling your electric shaver, try turning on the one devoid of knives. There is no automatic blocking in the absence of a head - the drive must rotate. It turns out - it's the head. Remove, disassemble, look. It is possible that the complete electric shaver buzzes and the knives refuse to rotate.

The next step is to check the mains voltage. OK - we disconnect the wire with the block from the case, measure the voltage by plugging it into the socket. Attention, be extremely careful to avoid electric shock. Check the cord by ringing a multimeter (tester). The signal passes uncertainly - it's a floating cliff. Try using a different cord to power your shaver. OK - problem limited to wire.

It is the turn of the chokes, harmonic filter capacitors. Testing is done differently depending on the specific design of the shaver. In a difficult case, the elements are soldered (removed) in turn, the integrity is examined:

  • chokes are ringing;
  • the capacitors are not swollen.

There are special devices - it will be useful to measure the denominations of the elements. The capacitance of the swollen capacitors is less than the number on the case. It is simply impossible not to notice.

You can go the other way. Disconnect the stators, measure the terminal voltage in both switch positions. Be careful to avoid electric shock. The multimeter probes are connected to the switched off device.

If no malfunction is identified, go to the stator windings. Call each one if you know the pin locations. The resistance of the windings is Ohm units. It is impossible to fix a shaver with a faulty stator at home.

The terminals ring in pairs - a little, there is no guarantee of complete serviceability. Carefully measure the output current of the voltage switch in both positions. Let's make a reservation right away, the Russians in the country use a nominal 230 volts, measurements in this position will be enough. If there is no current, the problem is limited to the stator.

You can wind the stator coils at home if you have the appropriate skills. You can buy suitable ones.

The next thing to do when repairing electric shavers is to examine the armature winding. Let's check the voltage value of the motor brushes. The voltage is present, the razor does not work - the matter is in the anchor winding. Rewind at home if you know the parameters of the wire, the number of turns, and other characteristics.

Check the stator windings and armatures with a multimeter. Each is removed from the electric razor and rings. You can also measure resistance.
