Reasons for intermittent working of electric wrench failure

There may be many reasons why an electric wrench may work intermittently. Here are some common reasons and their solutions:

1.Battery problem

Reason: Insufficient battery power, aging battery or poor battery contact will cause the electric wrench to work unstable.

Solution: Check the battery level to make sure it is fully charged. Try replacing the battery, cleaning the battery contacts to ensure good contact.

2. Switch failure

Reason: The switch of the electric wrench is damaged or has poor contact, which may cause intermittent work.

Solution: Check and replace the switch to ensure that the switch connection is normal.

3. Motor problem

Reason: Worn or damaged internal parts of the motor (such as brushes or bearings) may cause the electric wrench to work intermittently.

Solution: Check the status of the motor brushes and bearings, and replace or repair them if necessary.

4.Circuit problems

Reason: The internal circuit board or connecting wire is loose or damaged, which will affect the normal operation of the electric wrench.

Solution: Check the internal circuit board and connecting wires to ensure they are securely connected, and repair or replace them if necessary.

5. Overheating protection

Reason: The electric wrench overheats after being used for a long time, triggering the internal overheat protection mechanism, resulting in intermittent operation.

Solution: Let the electric wrench rest for a period of time and avoid continuous use for a long time. Check whether the cooling system is working properly.

6. Vibration causes looseness

Reason: During long-term use, vibration may cause internal components to loosen or wear.

Solution: Regularly check and tighten internal components to ensure that all parts are firmly connected.

7. Control module failure

Reason: The control module inside the electric wrench has failed, which may lead to unstable performance.

Solution: Check and replace the control module, and contact professional maintenance personnel for inspection and repair if necessary.

8. External environmental factors

Reason: Dust, moisture and other factors in the use environment may affect the work of the electric wrench.

Solution: Keep your electric wrench clean, avoid use in extreme environments, and store it dry.

Summarize

Reasons for an electric wrench to work intermittently may include battery issues, switch failure, motor issues, circuit issues, overheating protection, looseness due to vibration, control module failure, and external environmental factors.

Inspection and maintenance based on specific problems can effectively solve the problems of intermittent operation. Regular maintenance and correct use of electric wrenches will help extend their service life and ensure their working stability.
