In detail: philips hq 9160 razor do-it-yourself repair from a real master for the site my.housecope.com.
The three floating heads of the HQ5 razor with rotating blades and a compact electric motor (EM) generate low noise levels for a virtually silent, vibration-free shave. The shaver works from a standard household network or from a rechargeable battery placed in the body of the electric shaver. 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 automatic. In addition, PHILIPS HQ 5890 has special features that increase the comfort of the razor: indication of the remaining time of offline shaving; electronic signal about the need for cleaning; a sound signal of the notification about the discharge of the accumulator; indication of complete discharge and charging of the battery; the presence of a wall holder for hanging the razor. The round blades of the razor provide an optimal shave in any direction. The slots in the fixed knives are safe and securely guide even long hair into the cutting unit.
Self-sharpening razor blades stay sharp even after years of use. And finally, another important convenience - shaved hair remains inside the razor. The “Reflex Action” shaving system, which is based on a unique rotary blade system, creates maximum convenience. So, for a closer and more comfortable shave, the shaving heads follow the contours of the face.
The "Lift & Cut" system used in Philips shavers lifts the hair before cutting it. For sensitive skin, there are 9 convenient settings for the height of the fit of the movable knives to the fixed ones.

After removing the shaving block 4, it is necessary to unscrew the three screws at the bottom of the plastic housing 11 and remove it. Then you will need to remove the shearing unit 8 and separate the base of the plastic case 5 from the frame 3 by unscrewing the two screws that hold them together. Next, remove the three gears 6 and the link 7. Unscrew two more screws securing the ED 10, disconnect the block of the voltage switch 1 and the switch 2. And, finally, remove the ninth lever.
So, what kind of malfunctions can the owner expect? The most obvious is that when plugged into the network, 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 by testing its contacts with the device. A slightly more complicated procedure is ahead if the razor buzzes when turned on, but the engine anchor does not budge. Then you need to check how easily the anchor rotates. Remove the tendrils of the brush holder springs, releasing their pressure on the brushes, and with a sharp movement unwind the anchor through the drive gear. If the armature turns hard, loosen the two screws holding the brush 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 carried to the workshop. At home, such a malfunction cannot be eliminated. Interruptions in the work of the razor can also occur because the brushes get stuck in the brush holders. It is not difficult to check this. Turn on the razor and use an insulated screwdriver to gently press on the brushes. If the razor works, the cause of the defect may be that grease has got on the brushes or the springs are not pressing enough.
Take out the brushes and burn them one by one with a soldering iron, the oil will burn out, then sand with a fine sandpaper or needle 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 surface of the collector with a cloth moistened with alcohol or cologne. The next reason for dissatisfaction with an electric shaver is poor shaving quality. It is clear that stationary knives with a worn surface should simply be replaced. But it happens that the movable knives do not fit well to the fixed ones. Then one or two washers should be placed under the gear wheel, the leash of which presses the knife. Owners of electric shavers should be aware that every six months it is necessary to clean the collector of the armature of the electric motor and fill the oil seals with new grease. To do this, unscrew the fixing screws and remove the electric motor from the razor body. Remove gears. Clean the collector plates with fine sandpaper, and gently clean the grooves between the plates with the tip of a knife. Then blow off the coal dust.
First, add two or three drops of MVP or MP-704 oil into the upper stuffing box, and then into the lower one (Fig. 2). Lubricate carefully, being careful not to get oil on the carbon brushes.
When assembling a cleaned and oiled razor, be careful. Install rubber and metal washers correctly. If the carbon brushes are worn out, they must be replaced. Before installing the brushes in their places, make grooves in them so that the brush holder spring cannot come off from its intended place. The carbon brush should enter the brush holder completely freely, without effort. If the brush is large, it should be sharpened with a personal file or emery cloth.
The electric shaver (Fig. 1) has three floating HQS shaving heads with rotating blades and a micromotor for a quiet, vibration-free shave.
The electric shaver is powered by an alternating current mains (mains voltage is selected automatically) and from a battery built into the body of the razor. Environmentally friendly nickel-metal hydride cells with high energy intensity are used. Charging the battery for an hour allows you to shave for three weeks without connecting to the mains.
Optical indication of recharging is used. This model has special features that increase the comfort of the razor:
indication of the remaining time of autonomous shaving;
electronic signal of notification about the need for cleaning;
a sound signal of the notification about the discharge of the accumulator;
indication of complete discharge and charging of the battery;
wall holder for hanging the razor.
Round blades provide a quality shave in any direction. Slots in the fixed blades guide even long hair safely and reliably into the cutting unit.
Self-sharpening razor blades stay sharp even after years of use. And finally, another important convenience - shaved hair remains inside the razor.
The Reflex Action shaving system, which is based on a rotary blade system, creates maximum convenience. So, for a closer and more comfortable shave, the shaving heads follow the contours of the face.
The Lift&Cut system used in the razor lifts the hair before cutting it. For sensitive skin, there are nine convenient settings for the height of the fit of the movable knives to the fixed ones.

All the best, write
Do-it-yourself repair of electric shavers is within the power of the master.Soberly assess the skills you have, if you do not see the difference between a choke and a capacitor, you are afraid to measure the voltage of 230 volts without endangering people's lives, it is better to discard the idea. To clean the mechanism when the electric razor does not cut, everyone will master. But brag to your friends: 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 on the rotors of electric motors. Before considering an independent repair of an electric shaver, we will describe the cleaning process. In most cases, when the device refuses to form beards, it means that the working head is dirty. The electric razor set is supplemented with a brush and a special aerosol. We learn the purpose of things.
The head of the electric shaver lasts no longer than 1 year. After it is considered: it's time to replace. Once every three weeks it is recommended to clean the unit. In the case of a rotary electric shaver, start with the outer foils. Gently go around each brush with a brush, sweeping out the hair trimmings.
After the block of knives is unfastened from the body of the electric shaver. The node is disassembled into its component parts. A 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:
plastic frame;
holder;
two or three pairs of cutting surfaces, consisting of:
rotary knife;
grids.
Each blade is shaped like a flange bushing. A segment of a thick-walled tube, at one end there is a washer two to three times the diameter. On the resulting platform with a hole in the middle, there are bevelled protrusions provided with cutting surfaces around. Be careful, even in a blunt state, electric razor blades can cause harm to health. By the way, it concerns grid models. Handle knives carefully. Everyone has seen the net. Round parts with slits in a circle that slide along the skin when shaving.
We sweep with a brush each element of the head of the electric razor, if an aerosol is supplied in the kit, we process knives and nets, and we re-clean. It remains to assemble the nodes together by setting them back.
A slight 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 electric shaver does not work, still does not cut - the operation was performed incorrectly.
Disassemble the shaver following the above instructions and reassemble. Didn't help, time to buy a new head.
Time to take a brush. You can't do it. Even soft touches of the bristles can damage the mesh's proper shape. The electric shaver does not work well, the blades may be blocked. It is difficult to straighten the mesh at home without harming it. Electric razor repair shops will become useless assistants.
First. If the razor is washable, cleaning is carried out after each use. Learn one thing. An electric razor is good after buying the first 3-5 procedures. Then the bacteria begin to multiply rapidly in the head, each use brings irritation to the skin, which is powerless to remove with special means for personal hygiene. Try instead to find a disinfectant spray, treat the blades before washing. Naturally, the means must be intended for these ends. Try holding your knives under a UV lamp to block bacteria from growing.
With regards to other types of electric foil razors, they are cleaned every few procedures, without the use of water. To this end, the mesh is carefully removed. Cleanse the remnants of hair by blowing as it should. Try, removing the head, knock the end of the table gently. Partially rids the shaver foil of dirt. The block of knives is fanned with a brush. If there is an aerosol in the kit, use it for additional cleaning of the device.
Similarly to the previous case, try out the electric shaver after assembly. The effect is unsatisfactory - it's time to buy a new head.
The internal structure of a rotary type electric shaver is simple.An engine is mounted inside, which transmits torque to two or three knives by means of an output shaft and an eccentric gear. Outside, 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 working from different networks, the stator coil has four windings. Copper wires clad with cambric have a fixed color.
Before disassembling an electric shaver, try turning it on without knives. There is no automatic lock in the absence of a head - the drive must rotate. It turns out - it's in the head. Take it off, take it apart, take a look. A variant is possible when the electric razor assembly buzzes, the knives refuse to rotate.
The next step is to check the mains voltage. In order - disconnect the wire with the block from the case, measure the voltage by plugging it into a power outlet. Attention, be extremely careful to avoid electric shock. Check the cord by ringing with a multimeter (tester). The signal passes uncertainly - it's a floating cliff. Try powering the shaver with a different cord. OK - the problem is limited to the wire.
It is the turn of chokes, harmonic filter capacitors. Depending on the specific design of the electric shaver, testing is carried out in different ways. In a difficult case, the elements are soldered (removed) in turn, the integrity is examined:
chokes are ringing;
capacitors are not swollen.
There are special devices - it will be useful to measure the values \u200b\u200bof the elements. The capacitances of swollen capacitors are less than the number flaunting on the case. It is simply impossible not to notice.
You can go the other way. Disconnect the stators, measure the voltage of the terminals in both positions of the switch. Be careful not to get electrocuted. The multimeter probes are connected to the switched off device.
If no fault is found, go to the stator windings. Call each if you know the location of the pins. Winding resistance is units of Ohm. It is impossible to repair a razor with a faulty stator at home.
The terminals ring in pairs - not enough, there is no guarantee of full 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 value of 230 volts, measurements in this position will be enough. If there is no current, the problem is limited to the stator.
Stator coils are wound 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. Check the voltage value of the motor brushes. The voltage is present, the razor does not work - the point 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, armatures with a multimeter. Each is removed from the electric razor, called. You can also measure resistance.
