Anonymous users2024-02-14ElectricWrenchSometimes it turns, sometimes it doesn't. The switch is on, and the light of the switch is on. The wrench head in front of the electric wrench clicks.
In this case, it should be that the switch is broken, or his motherboard is broken。We can use a screwdriver.
Open his case to see if the power cord is broken, and if not, you can change the switch.
If the switch doesn't work after changing, then it should be replaced with a motherboard. Electric wrench this reactance.
There is no burn-out, because it is brushless, so there is no burn-out, only his motherboard is broken, or its switch is broken.

Anonymous users2024-02-13There are only 2 situations in this case: the first wire is broken and the power cord is replaced (test method: one hand press the switch and the other hand to shake the line on the tail of the electric wrench to see if the electric wrench will be de-energized, in the line on the tail of the plug), the second carbon brush contact is not good to change the carbon brush.
As for saying that the rotor is broken, it is purely to fool your money, if the electric trigger does not turn, you can turn it with your hand and turn your head, then the rotor is broken.

Anonymous users2024-02-08Summary. Answer: If this kind of electric wrench, this kind of problem may be a short circuit in the circuit or insufficient battery power, or it may be a problem with its internal structure, you should disassemble it and check it.
Answer: If this kind of electric wrench occurs, the problem may be that there is a short circuit in the circuit or the battery is insufficient, and there may be dust damage, which may be a problem with his internal structure, and you should disassemble it for inspection.
Answer: The possible reasons are: 1. The carbon brush is worn and cannot be contacted. 2. The power cord is broken and lacks lead. 3. The switch is broken. 4. The rotor commutator burns out. 5. The stator coil burns out. 6. The bearing is worn, and the balance is seriously swept.

Anonymous users2024-02-07Dear, hello, I'm glad to answer for you, the reason why Dongcheng electric wrench is boring is as follows: the electric wrench is boring, see if the power is insufficient, if so, use it after it is fully charged. If it is still boring after charging, it is necessary to consider whether the battery is aging and cannot be charged.
If that's the case, then just change the battery. The relative lithium battery will have much better power than the battery next to the nickel-chromium segment. Two:
If the electric wrench is fully charged, it still feels weak to use. Then you can use the universal embroidery removal notice to rotate the bearing part of the electric wrench, spray for 20 seconds, and you can watch while spraying, and let the motor rotate. This lubricates the rust and damping areas inside.

The electric wrench will turn for a while and will not turn for a while, it should be that the switch is broken, or its motherboard is broken; You can use a screwdriver to open his case to see if the power cord is broken, and if not, you can change the switch; If the switch doesn't work after changing, then you have to change the motherboard. The reactance of the electric wrench is not burned out, because it is brushless, so there is no burnout, only his motherboard is broken, or its switch is broken.
Hello! I am Life Tea Renqing, your question has been received, sorted out, and I will reply to you within five minutes.
The electric wrench will turn for a while, and the car will not turn for a while, the switch should be broken, or its motherboard is broken; You can use a screwdriver to open his case to see if the power cord is broken, and if not, you can change the switch; If the switch doesn't work after changing, then you have to change the motherboard. The reactance of the electric wrench is not burned out, because it is brushless, so there is no Lu Zhao burned out, only his motherboard is broken, or its switch is broken.
Hope mine is helpful to you, thanks!
Satisfied to give a thumbs up, and finally wish you a happy life!

Anonymous users2024-02-05Dear, the electric wrench Sun hand will not turn when it turns, which may be caused by a variety of factors. The following are some reasons that may cause the electric wrench to stop turning once and the corresponding solutions:1
Electric wrench power supply problem: The electric wrench may not work properly, if the power supply is not connected properly or the battery is not sufficient, the electric sail chain wrench will not rotate. Check that the power supply** is working properly and that the battery needs to be charged or replaced.
2.Incorrect torque adjustment: If the torque adjustment is not normal, it may cause the electric wrench to stop turning once it is turned.
The torque needs to be adjusted according to the actual needs in order to achieve the required torque. 3.Motor Failure:
If the motor fails, it may cause the electric wrench to turn once and not spin. It is necessary to check whether the motor is working properly or replace the damaged motor. 4.
Damage to mechanical parts: If the mechanical parts are damaged or worn, it can also cause the electric wrench to stop turning once it turns. It is necessary to inspect the mechanical parts for damage and replace or repair the damaged parts.
It should be noted that since electric wrench equipment involves personal safety, it is recommended to seek professional help for inspection and repair.

Hello, this kind of electric wrench, and the difference out of the lead brother is now this kind of problem may be a short circuit in the circuit or insufficient battery power, or it may be that there is a problem with his internal structure, you should take it apart to check the excitation skin.
The possible reasons are: 1. The carbon brush scrambling pin cannot be touched by wear. 2. The power cord is broken. 3. The switch is broken. 4. The burning bucket section of the rotor commutator is broken. 5. The stator coil burns out. 6. The bearing is worn, and the chamber is seriously swept.
Cash domestic production of electric torque wrench, only a single current to control the torque, because the torque output of the electric wrench and voltage, speed, reverberation electromotive force are related, so that the torque output accuracy can not be guaranteed, the error is more than 30%, the control part and the wrench can not be connected into a whole, the overall volume is large, the weight is heavy, so the operation is inconvenient, especially for high-altitude work is not suitable. Although the imported fixed torque electric wrench adopts an integrated design, it relies on manual adjustment of the gear, and the operation needs to be adjusted against the calibration torque value table, setting the torque, the operation is inconvenient, and it is easy to make operation errors. Stehr's digital multi-indicator chip control, digital stepless setting torque compact structure of single-speed constant torque electric wrench completely overcomes the common problems of imported and domestic electric wrenches.
