For many young people who like to decorate their houses by themselves, there must be a variety of electric tools in their homes. The fun they get can be imagined. But once they encounter decoration problems and the machine happens to be damaged, the maintenance of electric tools becomes a headache. Instead of looking for maintenance agencies to be slaughtered, it is better to upgrade the repair skills once.

According to the types of common electric tools, we divide the maintenance methods into the following categories:

Maintenance of Electric Tools I. Damage of Drill Pin Gear

I believe that the first reaction of many people when they see this picture is that this electric drill is completely laid off. If you want to change everything, you will have enough money to buy a brand new electric drill. Don't worry, just find the spare gear (recommended at home) and put two cushions on it before installing it. Let the gear move backward. If the original half-circle key is long at this time, remove the half-cut. Next, the screw holes of the bearing seat are removed several centimeters, so that after installation, the gear of the rotor will grow out of the centimeter just now, which also represents the shorter electric drill. Finally, remove the worn parts of the rotor gears and reinstall them so that they can continue to be used.

Maintenance of Electric Tools II. Electrical Faults of Hammers

The electrical faults of the electric hammer mostly belong to the breakage of the leather wire, which is the most common case when the handle is basically broken. It is very simple to check the bad contact of the carbon brush machine. First of all, it is observed whether the carbon brush section is well contacted and the hemp surface is badly contacted. Another way to check is to connect the universal pen to the motor appearing end and press two screwdrivers on the brush socket and rotor at the same time. If the motor is not faulty by electricity, the other way is bad contact of the carbon brush or burned out of the stator earrings.

Electric Tool Maintenance III. Carbon Brush Motor Rotation Consumption of Carbon Brush

Many people often guess that this situation is due to the matching type of carbon brushes. In fact, this situation is often caused by different wear and tear of the rotor commutator. It is more likely that the overload use of armature bending, at this time, only one rotor can be replaced, but remember not to replace a new carbon brush.

_Several common maintenance problems of electric tools are introduced here today. Next, the most important basic daily maintenance methods are discussed. For most people, electric tools are not commonly used tools, so for long-term shelved electric tools, it is necessary to measure insulation resistance before use, and secondly, when replacing parts, it is necessary to use the original parts. The qualified products with the same technical parameters, the added lubricants must be qualified products and so on.

_Conclusion: Damage to electric tools can indeed bring a lot of trouble to life. For most electric tools, daily maintenance is the key.
