ZS 718 manicure machine has established itself as a reliable solution for craftsmen who value stable engine operation. This model is often found in mid-level salons and home studios due to its optimal price-function ratio.
The device is equipped with a powerful motor that can withstand long-term loads without overheating. Micromotor ensures smooth operation, which is critical when working with thin areas of the nail and when removing artificial coatings. Understanding the technical nuances will allow you to extend the life of the tool and avoid common operating mistakes.
Many novice specialists confuse various modifications of control units, but it is ZS 718 distinguished by its versatility. It is compatible with a wide range of attachments, making it suitable for both hardware manicure and pedicure. In this article we will look in detail at how to properly set up the device and what to look for when purchasing.
Technical characteristics and design features
The basis of performance is the DC motor housed in an ergonomic housing. Power of this device usually varies in a range sufficient to work with carbide and ceramic cutters. It is important to note that the speed stability is maintained even with light pressure on the nail, which prevents the tool from jamming.
Cooling system in the model ZS 718 implemented through ventilation holes located strategically on the body. This allows heat to be transferred away from the internal components. It is critical to keep these holes clean, as clogging with dust can lead to overheating of the motor and reduced brush life.
The button for switching the direction of rotation (reverse) is usually located on the front panel of the unit. This makes it possible to quickly change the direction of movement of the cutter without taking your hands off the work process. For left- and right-handers, this is a significant convenience, allowing you to process the side rollers at different angles.
⚠️ Attention: Do not cover the operating device with towels or napkins. Impaired air circulation inside the ZS 718 housing will lead to thermal shock of the engine and melting of plastic elements.
The weight of the handpiece (handpiece) also matters. A tool that is too heavy tires the master’s hand, causing trembling in the hands. Construction ZS 718 Designed to balance metal strength and overall weight, reducing wrist strain during long periods of use.
Setting the speed and working with the pedal
Adjusting rotation speed is a key skill for safe operation. On the front panel there is a rotary regulator that allows you to smoothly change the number of revolutions per minute. Speed range Typically ranges from 0 to 35,000 rpm, which covers the needs of most procedures.
For beginners, it is recommended to start at low speeds, gradually increasing the speed as you gain experience. High speed is necessary to remove a thick layer of gel polish, while cuticle polishing requires minimal values. The wrong choice of mode can lead to burns of the nail bed or damage to the matrix.
Connecting a foot control pedal significantly expands functionality. The master gets the opportunity to control the start and stop of the motor without looking away from the client. This is especially convenient when working with drum cutter or when grinding feet, where constant control of the moment of contact is required.
What to do if the pedal is not included?
If your ZS 718 package does not include a pedal, but there is a connector for it on the rear panel, you can purchase a universal pedal with a 5-pin connector. This will significantly improve the ergonomics of the workplace.
When using a pedal, it is important to adjust the touch sensitivity. A move that is too tight can cause leg fatigue, while a move that is too light can cause the engine to start randomly. The optimal setting allows you to confidently feel the switching threshold under your fingers.
Compatible with attachments and hand blocks
Versatility of the device ZS 718 consists of a standard collet clamp. The most commonly used clamp 2.35 mm or 3.0 mm, allowing you to install most popular attachments on the market. However, before purchasing expensive cutters, always check the specifications of your hand block.
Different types of work require different attachments. Below is a table of correspondence between nozzles and operating modes:
| Nozzle type | Recommended speed | Purpose | Material |
|---|---|---|---|
| Ceramic cutter | 15 000 - 20 000 | Removing gel polish | Ceramics |
| Carbide | 10 000 - 15 000 | Removing acrylic/gel | Metal |
| Diamond | 5 000 - 10 000 | Cuticle treatment | Steel/Diamond |
| Polisher | 3 000 - 5 000 | Final sanding | Silicone |
The nozzle can be replaced only after the motor has completely stopped. The rotating chuck can injure your fingers. The clamping mechanism (collet) requires periodic lubrication with special oil to prevent jamming.
Do not use attachments with damaged shanks. A bent rod creates runout that destroys the motor bearings. ZS 718. Vibration is also transmitted to the master’s hand, causing occupational joint diseases.
☑️ Check before installing a new cutter
Ergonomics and safety at work
Long-term use of the device requires compliance with ergonomic rules. Vibration from the motor, transmitted through the handle, can cause numbness in the fingers. Model ZS 718 often equipped with handles with anti-slip coating, which improves grip.
The correct position of the master's hands also affects the result. The elbows should be supported, and the hand should move smoothly, without jerking. Sudden movements can cause the cutter to slip and injure the client. Always support the client's finger with your other hand, creating a fulcrum for the working cutter.
Client safety is a priority. Before starting the procedure, you must ensure that the nozzles are sterile and the work area is clean. The device must be placed on a stable surface to prevent it from falling during operation.
⚠️ Attention: It is strictly forbidden to use the device near flammable liquids. Sparking of the brush motor (typical for models like ZS 718) can cause ignition of alcohol or acetone vapors.
Regular breaks in work are necessary not only for the client, but also for the master. Let the machine cool down after 40-50 minutes of continuous operation, especially if you are working at high speeds with hard materials.
Care, cleaning and maintenance
Extending service life ZS 718 directly depends on the quality of service. The main enemy of electronics and mechanics is nail dust. It penetrates inside the case and settles on the contacts. Regular blowing with a compressor or using a special cleaning spray is mandatory.
The collet clamp must be lubricated after each work shift or sterilization. A drop of oil is applied to the cutter shank before installation, after which the motor is started at low speed for 10-15 seconds to distribute the lubricant.
The housing should be wiped with a soft cloth slightly moistened with a disinfectant solution. Aggressive chemistry may corrode the plastic or wash off the markings on the regulators. Avoid getting liquid into the vents.
Use disposable protective covers for the device handle. This will prevent dust and disinfectant from getting inside the mechanism, and will also simplify processing between clients.
If you notice the appearance of extraneous noise, hum or a burning smell, use must be stopped immediately. Such symptoms indicate worn bearings or problems with the motor winding. It is better to entrust repairs to specialists.
Troubleshooting
During operation, typical problems may arise that can be solved independently. For example, if the device ZS 718 does not turn on, check the integrity of the network cable and the fuse in the connection socket. Often the problem lies in a blown fuse.
If the motor hums but does not rotate, the collet may be stuck or the brushes may be worn out. In the first case, careful cleaning and lubrication will help. In the second, replacement of graphite brushes is required, which is a standard procedure for commutator motors.
Unstable speed may indicate problems with the control board or pedal contacts. Check that all plugs on the rear panel are securely connected. Contact oxidation is a common cause of malfunctions.
Timely replacement of brushes (every 500-800 hours of operation) prevents burnout of the engine commutator and maintains the power of the device at its original level.
If sparking appears inside the housing (visible through the ventilation holes) in a volume exceeding the norm, the commutator-brush assembly should be diagnosed. Light sparking is acceptable, but bright flashes are a sign of trouble.
