Why does the hair clipper tear?
The problem occurs with both new models and old ones. If the device starts to twitch, causing discomfort to the customer, the source of the problem is in the blades. Blades of the appliance are tightly touching and moving, cutting the hair.
If hair is not cut for some reason, it begins to pull along with the course of the blades. Options for answering the question of why your hair clipper bites:
- Insufficient power. The more revolutions per minute the tool has, the better the cuts. The good models have an impressive weight because they have a high-speed motor;
- Insufficient sharpening of the device. If the tool has been working fine for a while, but then it starts to twitch after 2 to 3 months, you just need to sharpen the cutting edges. After that, the problem usually disappears.
If the machine has been used for less than a month after purchase, and the question of why the machine pulls hair is relevant, you need to find out the manufacturer.
Note: Hurricane Florence weakened into a tropical storm, killing at least 13 people.
If it is a Chinese fake, edge sharpening will not help.
Hair clipper device
We hope to teach those wishing to know how to repair a hair clipper machine. The question is non-trivial, as it will seem at first glance deceived by the apparent simplicity of design. Surprisingly, the only book describing hair clipper repair is by Lepayev, dating back to 1970. Drop in interest, simple design? Professionals are few and far between, no time to write manuscripts, pressing issues. Regardless of the principle of the hair clipper machine inside there are:
- Transformer, the primary winding of which is often designed to work with voltages of 127, 220 V.
- Stator coils. Two according to the number of supply voltages.
- Steel core.
- Rocker, pendulums, other similar mechanism that starts to vibrate when an alternating field appears.
- Knife block formed by movable and fixed parts.
- Pulsed power supplies have gradually replaced bulky transformers with molded cores. The small size of digital technology attracted the designers of hair clippers.
Is there a pendulum inside the hair clipper (Moser), the rocker, both held by two return edge springs. Stator does not touch the rotor, otherwise, when running, producing a grinding sound. A special screw mechanism serves as a regulating device. The pendulum is often mounted on a bearing. Falls out. there will be a noise. The moving part is made as light as possible, the blade can sit on a plastic part (the specific gravity of polymer is many times less than steel). The pendulum may crack in the bearing area. Used to have to put a clamp, change the part, today’s adhesives will hold firm. Try Titanium.
Hair clippers are happy with the coils. Regular chokes, a high school kid can wind. Learn the brand of wire, buy a section of the right length at the market, covered with lacquer insulation, make a device for rewinding, start the repair of the hair clipper with your own hands. The old coil is wired. Helps to make sure: the fault is hidden here, not the mechanical part. A burned transformer (not a pulse transformer), rewinding is not difficult. The second step is to start laying the turns. Use a device made up of two pairs of racks located opposite each other on different edges of a long board. The axes of one supports the old coil, the other accepts the wire. If you notice a break in the beginning or end, don’t buy new wire at the market, wind back the existing wire, subtracting the torn part. It is important to maintain the correct number of turns, the location of the leads.
New coils are wound with the described device. Lay the coils tightly, the glue is excessive, the wire is held by hand. The tension helps to lay the coil with the wire in even layers. The coils are wound with the shuttle method, from one end to the other. After completing the procedure, you need to ring the coil, make sure the integrity of the wire. If one voltage is used at home, the wire is longer from one unnecessary choke is used to restore the burned out. Enough length. the market will wait.
Hair clipper device is unsophisticated. Motor, torque transmission circuit. The hair clipper anchor rarely breaks, except in the cracked case discussed above. Prepare to lubricate, clean the device regularly. Use VNIIMP. 260, soft brush. The stroke of the armature is sometimes adjusted with a screw, make sure that in all positions the teeth of the moving part do not protrude beyond the bed.
Many copies have a trimmer for grass, which takes power from the same motor through a transmission mechanism.
Why the hair clipper won’t cut your hair
To pay tribute to the past, in some hair salons, masters still use manual hair clippers. They were long ago replaced by electric hair clippers, which are very popular among consumers. They are used both in hairdressing salons and at home (adjustment of hair clippers is simple, which makes it easy to use for the average person).
How a hair clipper is designed
On the market, there are only a few types of machines prevail:
- Cordless (these are the lightest and least noisy, on average working condition about an hour, more suitable for home use);
- rotary (thanks to the powerful motor can work uninterruptedly for a long time, has a considerable weight, so that the motor does not overheat, built-in fan, powered by electricity);
- the vibrating ones (lighter than rotary ones, they overheat quickly, so the continuous work time is limited to 20 minutes, they vibrate, are powered from the network).
The machine can cut not only the head but also the armpits
But the construction of the machines is the same in all types, with a few differences. The main elements of the complete set of the device:
- body (made of plastic or plastic);
- a small motor (mini-motor) or coil (for the vibrating model);
- the head of the machine;
- interchangeable blades;
- In the tail part is the connection of the cord (power) to the body.
Professional machines Philips, Moser, Babyliss, Remington, Scarlett, Vitek and others
The rotary machine can be operated by DC and AC current, which drives a motor. On the shaft of the motor there is an eccentric (an intermediary between the motor and the blades), which ensures the movement of the blades.
The principle of operation of the vibrating device is similar, only the current passes through a coil to the vibrating head, which sets in motion the knives.
On the body of the device (most often on the head) there is a switch button. The auxiliary inscriptions on/off help to understand what state the device is in.
On the body is also the manufacturer information, the number and year of manufacture of the product, as well as its voltage and power. On the head of the device there are a pair of pins with slots, on which the blades are attached.
It is good if the charging jack is made waterproof
When you plug the cord into the socket, the hair clipper gets access to electric current, and is therefore ready to work.
How to sharpen hair clipper blades: how to set up and adjust your hair clipper machine
The question arises: “How to adjust the hair clipper machine?” Let’s get this straight.
Preparing and adjusting the hair clipper is the first thing to do before using it. To avoid corrosion, in the manufacture of the device is lubricated with a special agent. To wash off the grease, the blades must be thoroughly washed with gasoline, wiped dry with a rag and all parts (except the teeth of the blades) lubricated with special oil.
A good craftsman is not only able to cut, but also to make drawings
Before you plug in the machine, you must check whether the voltage in the network corresponds to the voltage that is specified on the device.
Do not be surprised if the machine housing gets a little warm during operation. this is normal. It is not recommended to use the device for half an hour or more, it can overheat and break. The setting of the hair clipper blades (setting or changing blades) is done by yourself. It is necessary to adjust the position of the blades, that is, adjust the desired gap. This is done with a screwdriver, adjusting the screw.
Wet or dirty hair can cause knife corrosion, so it’s better to cut hair when it’s clean and dry. To use the device for a long time, it is recommended to avoid getting water or other liquids on the housing and the motor.
Is it possible to repair the blades and nozzles of the actual machine at home?
Parts of an electric typewriter and its blades have a certain service life, exceeding the specified one leads to malfunctioning of the machine and the blades get blunt quickly. As a consequence not all hair is cut (the device misses wisps of hair) or the device pinches the hair, and that is unpleasant for the person being cut.
The master will easily do the desired hairstyle
Where to buy parts
In this case, you need to fix the device (adjust the blade in the hair clipper so that the machine works properly): disassemble the blades, rinse them thoroughly with gasoline, wipe them dry, lubricate with machine oil and reassemble. If you use the power tool frequently and for a long time, it is advisable to have the blades of the power tool sharpened in a special workshop. Many modern machines have self-sharpening blades.
So they only need to lubricate. Adjust the hair clipper (clean and lubricate the main parts) every 3-4 months. That is provided it is used intensively and every day.
The cutting blades of the machine require lubrication and timely sharpening
If the malfunction of the tool is due to dirt or the need to clean and lubricate the parts, it can be done by yourself. But often the failures are of a different nature, and only a master can eliminate them.
The most common types of failure: cord breakage; switch stops working; crack in the body; wear of the eccentric, breakage of the coil or pendulum; wear of return springs; appearance of unusual noise (causes may be different parts); problems with the battery or its charger; problems with blades.
Buying a machine for home will not only save a man or child time going to the barber, but also money. It will justify itself in the ease of use with proper care.
The hair clipper does not cut hair. what are the reasons?
Possible malfunctions in rotary hair clippers:
NOT CUTTING? Taking apart Hair clipper cleaning repair testing the motor
Problems with the wire (torn, burned out);
Malfunctions of battery powered models:
The problems are common for all models:
Not cutting hair clipper barber-what’s the matter?
In the past I wrote about typical malfunctions and other problems with hair clippers, but today I want to get back to this topic, because various kinds of complaints from users and sharpeners do not decrease.
In the market of professional shearers the niche is occupied by machines from Moser, Oster, Jaguar, Philips. Among hairdressers, Moser machines are the most popular. As usually it happens, what is in great demand, is often counterfeited. In my practice I often come across fakes Moser. Usually hairdressers shift any sins to the master sharpener. And master sharpeners also often do not understand after sharpening, why the machine does not cut as it should. Therefore, bad suspicions are shifted to the low-quality sharpening equipment.
Here is a case in point. A sharpener I know with a little experience complains that after sharpening the knives on the machine, sometimes they cut normally, and sometimes not. One day he came to me with another problem after sharpening. A man brought a Moser machine that he used to cut dogs. The friend sharpened the blades and tested it does not cut. Tries to resharpen, adjust, but nothing works. Hair cuts fine, but wool is not taken. I checked the knives, they are normally sharpened. I check the settings, I am interested in the construction of the machine and of the knife block, and suddenly I find the reason. And it is in the design of the machine (in the picture). Cutting animals (hair) is more problematic. hair. This is primarily due to the thickness. It is important to remember: The thinner the structure of the sheared skin, the higher the requirements for the quality of the blade pair. For shearing animals need a good quality machine. What does it mean? The upper blade should go over the big one. For this purpose in a design of the machine except for a pressing spring, there should be a guide groove on a small knife (on fig.) that it does not dangle and went accurately in a straight line back and forth on a surface of the big knife. Of course it is necessary to check the necessary and sufficient tension of the spring, providing free running of the small knife without vibration on the surface of the big one. Only under this condition, properly sharpened blades will cut not only the hair, but the wool as well.
In our machine this groove was not (in the picture above). And while working, the small knife not only did not go straight, but also bounced on the big one and worked poorly, so such a machine can go (with a strain)!) for hair cutting, but for wool will not suit at all. Such a design (a small knife without a guide) brand-name machines do not happen, so we can conclude that my acquaintance sharpener was dealing with a fake. Inexperienced sharpeners often find it difficult to find the cause of the machine malfunctions, which is not only in the improper sharpening of the knives, but also in the adjustment and construction of the machine itself. My sharpening training course discusses such problems in detail.
Universal grinding machine ShM-36 Supermaster
For high-quality sharpening knives clipper in domestic conditions master enough to equip the theoretical knowledge of the design and functional operation of the machine, but you must have a professional horizontal grinding machine type Sh-36 or ShM-36, which provide the highest quality sharpening knives clippers, knives meat grinders, coffee grinders and other tools in the home environment. On such a machine, the knives are sharpened with a special serrated tapered aluminum faceplate, which ensures proper contact of the knife pair.
How to fix clippers that don’t cut
Below in the video look quality machine on which you can properly sharpen the blades of not only hair clippers. but also grooming knives.
Seniors Wahl Clippers Not Cutting And Clippers pulling hair?? Service For Best Performance Ever
The sharpening problems are explained in more detail in the course on sharpening A. Sharp with new technology.
Why does the machine tear the hair??
The blades of the hair grinder move. and they’re supposed to be cutting the hair. Problems begin when the blades fail to cut for some reason. In that case, the knife grabs the hair and pulls it with it. Hair is already cut or torn while stretched. But the customer can already feel the suffering.
The logic is clear. There are two common reasons that blades don’t cut hairs the way they should.
The machine tears the hair because it does not have enough power
The power of the machine determines the number of revolutions per minute. That is, the frequency and speed of the blade. The speed at which the blade moves determines how fast it cuts. Let me draw a parallel. Imagine cutting a loaf in a very slow motion. So the knife will not cut it, but rather squeeze it.
Thus, if the motor power is low and the speed of the blade is not enough, the machine will cope with difficult hair through time. Complicated. That’s for example thick, stiff or thick hair. But when knives get blunt, low-powered machine will start to tear everything you encounter.
The machine pulls hair because the blades are dull
That’s the reason. even more common. So even a good machine can start pulling hair. Pay attention. If you have been working with this machine for a long time and there were no problems before, but now it starts to twitch. It’s most likely because the blades are blunt.
The logic is the same. a blunt knife does not cut the hair as it should be cut, but pulls it first. This is no good, the knives need to be sharpened. But please do not try to do it yourself if you are not a professional sharpener. Yes, you might be interested in trying to save money. but the savings often go sideways. It is quite possible that after an unprofessional attempt to sharpen the knives will have to throw out and buy new ones at all.
Why the hair clipper does not cut the hair
Most modern hair clippers on the type of work similar to the Soviet razors. They are indispensable equipment for professional hairdressers. Many consumers buy such devices for home use. But, as any technique, hair clippers can break down, so you need to repair them urgently. What may be the causes of malfunction of the device and whether you can fix them yourself at home?
Hair clipper device
There are 2 types of hair clippers, which differ from each other on the principle of operation.
This type of devices is the most expensive in the market hairdressing power tools and presented in two versions: devices running on the network, and cordless tool. Rotary clippers are distinguished by their reliability, high power and durability. The main driving element of this machine is the electric motor, the rotor of which is attached to the eccentric. As it rotates, the eccentric connected to the movable blade moves it in different directions. The unit also has a knife block consisting of a stationary part and a movable part.
In the stand-alone version, there is a rechargeable battery (battery pack) and a control board in the tool body.
This is a more budget-friendly version of the power tool for hairdressers than the one discussed above. This unit has a coil instead of an electric motor. In front of the coil is a pendulum containing a permanent magnet. When current flows through the coil, on its core the polarity of the magnetic field changes at a frequency of 50 Hz. Therefore, the permanent magnet in the pendulum changes its position all the time, and since the latter is connected to the moving blade, it is set in motion. Also in the apparatus, you can observe the power button.

Hair clippers please with coils. Common chokes, winded by a schoolboy. Find out the brand of wire, buy on the market a section of the right length, covered with lacquer insulation, make a device for rewinding, start repairing hair clipper with your own hands. The old coil is tested. Helps to make sure: the fault is hidden here, not the mechanical part. A burned transformer (not a pulse transformer), rewinding is not difficult. The second step is to start laying the turns. Use a fixture made up of two pairs of posts facing each other on different edges of a long plank. The axes of one supports the old coil, the other accepts the wire. If you notice a break in the beginning or end, don’t buy new wire at the market, rewind the existing wire, subtracting the broken part. It is important to maintain the correct number of turns, the position of the leads.
New coils are wound as described. The coils are laid tightly, the glue is superfluous, the wire is held by hand. The tension helps to lay the coil of wire in even layers. Coils are wound by the shuttle method, from one end to the other. After completing the procedure, you need to ring the coil, make sure the integrity of the wire. If one voltage is used at home, the wire is longer from one unnecessary choke is applied to restore the burned one. Enough length the market can wait.
The design of hair clippers is ingenuous. Motor, torque transmission chain. Hair clipper armature seldom breaks, except for the cracked case discussed. Lubricate, clean the device prepare to regularly. Apply VNIIMP. 260, soft brush. Sometimes the stroke of anchor is adjusted by screw, look that in all positions the teeth of moving part does not go beyond the bed.
Many models have a grass trimmer that draws its energy from the same motor through a transmission mechanism.
