Send a fax to inform them of the cylinder's serial number, production date, and whether the manufacturer retains the records. If explained clearly, a replacement certification can be issued. Application conditions: The cylinder must be used under normal ambient temperatures (-40 to 60 degrees Celsius), with a nominal working pressure greater than or equal to 0.2MPa (gauge pressure), and a pressure-volume product greater than or equal to 1.0MPa•L. It must contain gases, liquefied gases, or liquids with a standard boiling point equal to or below 60 degrees Celsius (excluding fire extinguisher cylinders, breathing apparatus cylinders, non-refillable cylinders, etc.). The cylinder must belong to a filling unit with a filling license or be an in-service cylinder approved by provincial quality and technical supervision departments. The cylinder manufacturer must hold a manufacturing license. The cylinder must not have been altered for unauthorized use conditions or undergone illegal repairs or modifications.

Why is there no response when pressing the car key to unlock the vehicle?

Reasons why the car key does not respond when pressing the unlock button: 1. The car key battery is dead and needs to be replaced. 2. It may be due to strong radio interference, preventing the vehicle from successfully receiving the key's signal. 3. Damaged components in the car key may cause it to malfunction. 4. The distance is too far for the vehicle to receive the signal. 5. The car battery may be dead. Steps to replace the car key battery are as follows: 1. First, remove the mechanical key to expose the gap in the plastic casing. 2. Use a tool to pry open the key cover once the gap is wide enough. 3. Note the orientation of the battery's positive and negative terminals and remember it before removing the old battery. The new battery must be installed in the same orientation. 4. Close the key cover, ensuring proper alignment to avoid damaging internal circuits during reassembly.

Why does the car still fail to start after replacing the spark plugs?

The reason why the car still fails to start after replacing the spark plugs could be a malfunction of the spark plugs themselves, or improper installation leading to poor contact between the spark plugs and the ignition module, resulting in no spark. Identifying the cause of the fault: For diagnosing faults such as the engine failing to start, the first step is to check the battery. It is essential to determine whether the engine's failure to start is due to insufficient battery power. Checking ignition timing: Slippage of the timing belt is the root cause of the failure to generate an electric spark and the engine's inability to start. Checking the starting system: For faults like the engine failing to start, the first task is to inspect the circuits in the engine's starting system. In its most basic form, the starting system's circuit generally includes the following fundamental components. Namely, the battery: Starting motor and the cables connecting these components. Of course, in addition to these, the ignition switch, starter relay or solenoid coil, and the vehicle's anti-theft system are also important parts of the starting system. Checking the quality of the electric spark: Once the starting system's circuits have been inspected and confirmed to be fault-free, attention should then be focused on why the engine cannot operate. The first thing to check is the engine's ignition system, which is also the simplest inspection task.

How to Retract Car Side Mirrors?

Different car models have different methods for retracting side mirrors. Generally, pressing the automatic folding button for the mirrors or rotating the button to the automatic folding position will simultaneously fold both exterior side mirrors. Introduction to side mirrors: 1. Side mirror folding is divided into two types: manual and electric. Manual folding requires the driver to reach out the window or get out of the car to fold the mirrors, which is both inconvenient and unsafe. This type of folding mirror is now rare. The other type is electric, which is more common. Its advantage is that the driver can fold the mirrors from inside the car, and the mirrors will automatically open when the vehicle is started. 2. The exterior side mirrors reflect the rear and side of the car, the lower mirrors reflect the front and lower part of the car, and the interior mirror reflects the rear of the car and the interior situation. Different purposes result in different mirror structures.

Is It Normal for the Seat Belt Date to Be Later Than the Vehicle Production Date?

It is normal for the seat belt date to be later than the vehicle production date. Specific reasons: The manufacturer that produces the vehicle does not produce seat belts. Car seats are purchased externally, and if the supplier delivers them late, the seats may be produced later than the vehicle. Sometimes, during vehicle assembly, the production dates of certain components may not match the vehicle's production date. This is because it is impossible to ensure all parts have identical production dates, and this discrepancy is unrelated to any issues with the vehicle itself. Solution: If there is a quality issue with the seat belt, the inconsistent production date can serve as valid evidence of the seat belt's quality. However, it does not prove any issues with the vehicle itself, and the vehicle warranty is based on the vehicle's sale date.
