Sooner or later, even the best quality equipment requires maintenance. If your hair clipper started to cope worse with your hair, jammed, or simply stopped turning on, don’t rush to throw it away. Often the problem lies in simple contamination of the mechanism or dried out lubricant. Correct disassembly The device allows for deep cleaning, replacing worn parts and extending the service life of the device for years.
Before proceeding with dismantling, it is important to understand that the design of the devices Philips may vary significantly depending on the series. These may be popular models of the series HC, professional HC7 or compact beard trimmers series BT. In this article, we will look at universal principles and nuances that will help you carefully disassemble the device without damaging the delicate plastic latches and electronics.
First, prepare your workspace. You'll need a clean, well-lit surface to avoid losing small screws and springs. Also stock up on a set screwdrivers (Phillips PH0 or PH1 are often required), a plastic card or a pick to open the case, and possibly tweezers. Ignoring preparation can result in small parts flying around the room and taking hours to find one lost gear.
Preparation of tools and safety precautions
Safety is the number one priority when working with electrical appliances. Although clippers are powered by low-voltage batteries, there is a risk of short circuiting or damaging the battery if not handled carefully. Before starting any work, make sure that the device off and disconnected from the charger. If the model has a removable battery, it is better to remove it immediately after opening the first compartment.
The set of tools must be selected carefully. Using unsuitable objects, such as a knife or awl, may damage the plastic fasteners found on the devices. Philips often designed as hidden latches. The ideal solution would be to use plastic spatulas for opening the case, which do not leave scratches and do not split the plastic.
⚠️ Warning: Never attempt to disassemble the device while it is plugged in or charging. This may result in electric shock or damage to the power controller.
Organize your space so that all screws and small parts go into separate containers. A magnetic mat or just a few bottle caps will help keep things organized. The loss of even one small screw can make assembly impossible or lead to vibration and noise during further operation.
☑️ Preparation for disassembly
It's also important to consider the type of battery inside. Most modern models use Li-Ion batteries that are sensitive to punctures and shocks. Damage to the battery casing may cause it to catch fire. Therefore, all manipulations inside the body require extreme caution and smooth movements.
Removing the blade block and external elements
The first step in any disassembly is to remove the external removable parts. In cars Philips the blade block is usually attached either to latches or to screws hidden under decorative trims. To remove knives, it is often enough to press the special latches on the sides of the head or gently pull the block up if it is supported on guides.
If the blades are removable, remove them by unscrewing the mounting screws. These often hide additional screws that hold the main body in place. Pay attention to the presence of rubber seals or gaskets that provide waterproof (if declared model Wet & Dry). Their integrity is critical to protecting electronics from moisture.
- 🔧 Carefully pry the knife with a plastic spatula if it cannot be removed by hand, so as not to damage the plastic teeth.
- 💧 Check the condition of the rubber seals - if there are cracks, it is better to replace them or carefully lubricate them with silicone.
- 🧹 Clean the space under the knives from hair and dust before further disassembling the inside.
After removing the blade block, access to the drive mechanism will open. A rod is often visible here, which transmits vibrations from the motor to the knives. It is in this zone that the bulk of pollution and old grease. Thorough cleaning of this assembly will often solve the problem of reduced cutting power without the need for complete disassembly of the housing.
Take a photo of the location of the knives and gears before removing - this will help reassemble them in the correct position and avoid jamming the mechanism.
Dismantling the case and accessing the internals
The most difficult stage is opening the main body. In modern trimmers Philips Manufacturers often abandon visible screws in favor of hidden fasteners and latches to improve ergonomics and moisture resistance. The screws may be hidden under decorative stickers, in the battery compartment, or under rubber grips on the handle.
Use a thin piece of plastic card or a special opening tool to go around the perimeter of the seam between the case halves. Move smoothly, hearing the characteristic clicks of opening latches. Do not use excessive force; if the housing does not come apart, you have missed a hidden screw or retainer. Forced separation will cause the plastic ears to break.
| Mounting type | Location | Tool | Risk of damage |
|---|---|---|---|
| Screws PH0/PH1 | Under the sticker/in a niche | Phillips screwdriver | Thread failure |
| Plastic latches | Along the perimeter of the seam | Plastic spatula | Broken ears |
| Rubber plugs | On the handle/bottom | Tweezers/Needle | Rubber rupture |
After successfully separating the body halves, the internal layout will open before you. Here are located electric motor, control board, battery and swing mechanism. Be careful: some models have cables or wires connecting parts of the case (for example, if the power button is on one half and the board is on the other). A sharp jerk can break the contacts.
Dismantling the engine compartment and mechanism
Inside the housing, the main interest is the “motor-eccentric-gear” combination. In cars Philips An eccentric mechanism is often used to convert the rotation of the motor shaft into reciprocating movements of the knives. This is where it is most often required lubricant or replacing worn parts.
To access the mechanism, you may need to remove the retaining brackets or unscrew additional screws holding the motor unit. Pay attention to the order of the gears. If there are several of them, remember or photograph their relative positions. Mixed-up gears can cause jamming or excessive noise.
⚠️ Attention: When removing the motor, be careful with the wires. They are often soldered directly to the board, and careless movement can tear the conductor off the pad, requiring soldering to repair.
Inspect the bushings or bearings in which the motor shaft rotates. If there is a black coating visible there or there is no lubrication, the mechanism will work with overload. Clean off old grease residue with solvent or alcohol before applying new grease. Use only special synthetic lubricants for power tools, as regular oils may thicken or leak.
Nuances of mechanism lubrication
Use lithium grease or special compounds for high-speed mechanisms. Do not use WD-40 as a lubricant - it is a solvent and will wash away factory lubricant residue and accelerate wear.
Working with the battery
Replacing or servicing the battery is a common reason for disassembling trimmers. Philips. Over time, capacity Ni-MH or Li-Ion cells drops and the device stops holding a charge. The battery is usually located at the bottom of the handle and is secured with plastic holders or glued.
When removing the battery, pay attention to the polarity of the connection. The positive and negative contacts must be connected strictly according to the markings on the board. An error in polarity when installing a new element can instantly damage the control board or the battery itself.
- 🔋 Check the voltage of the old battery with a multimeter - if it is below 1.2V (for Ni-MH) or 2.5V (for Li-Ion), the element is deeply discharged.
- 🔌 Make sure that the contacts on the new battery match the shape and size of the original ones.
- 🛡️ Insulate the battery contacts when working inside the case to avoid accidental short circuit with the tool.
If you change the battery, try to choose an analogue with the same capacity and dimensions. Installing an element with a larger capacity may not be physically possible, and a smaller capacity will reduce operating time. In some cases, you can re-solder the contacts using a low-heat soldering iron to avoid damaging the thermoplastic battery case.
Cleaning, lubricating and assembling the device
After all parts have been disassembled and defects have been eliminated, the maintenance stage begins. Thoroughly clean all plastic and metal parts to remove old grease and hair. For metal parts you can use a brush and alcohol, for plastic parts you can use a dry cloth or a slightly damp cloth.
The lubricant is applied in a thin layer to the rubbing surfaces: gear axes, engine bushings and blade block guides. Excess lubricant is just as harmful as its absence: it will be squeezed out during operation and mix with dust, forming an abrasive slurry that will accelerate wear.
Assembly is carried out in reverse order. Make sure that all cables and wires are laid in their channels and will not be pinched by the housing when closing. When connecting the halves of the housing, press evenly around the perimeter until all of them click. latches. If the housing does not come together easily, do not push - check that the internal components are seated correctly.
High-quality assembly depends on the cleanliness of the contacts and the correct laying of the wires - any pinched wire can cause a short circuit or intermittent operation of the motor.
Common problems and their solutions
Even after proper disassembly and assembly, nuances may arise. If the machine hums, but the blades do not move, the eccentric may have slipped off the motor shaft or the plastic gear tooth may have broken. In such cases, it is necessary to replace the damaged part with a new one.
If the device operates jerkily, the problem may be oxidized contacts of the battery or power button. Wipe the contacts with alcohol or use a special contact cleaner spray. This often returns the device to stable operation without the need for complex repairs.
If the machine stops turning on completely, check the integrity of the fuse on the board (if there is one) and the presence of voltage at the battery terminals. Sometimes the problem lies not in the mechanics, but in the failure of the electronic charge controller, which requires deeper knowledge in electronics for repair.
Is it possible to wash disassembled parts of a Philips machine under water?
You can only wash metal knives and plastic cases if they do not contain electronics. The board itself, the motor and the battery should absolutely not be wet. Even if the model is marked Wet & Dry, this refers to the assembled state, not the disassembled state.
How to lubricate the mechanism of a hair clipper?
Special oils for machines (often included) or synthetic lubricants for high-speed mechanisms are ideal. Do not use vegetable oil (it will harden) or WD-40 (it will wash away the factory lubricant).
What to do if the plastic case latch breaks?
If the latch breaks off, the case can be carefully glued together with a special glue for plastic or secured with a thin wire/tie in the place of the chip. The main thing is to ensure a tight fit so that the mechanism does not vibrate.
How often should the machine be disassembled and cleaned?
Preventative cleaning of the knife block should be carried out after every 3-4 haircuts. It is recommended to completely disassemble the mechanism and lubricate it once a year or when signs of performance deterioration appear (noise, heating, loss of power).
