How to adjust the air pressure of tunnel battery car
1. Know the correct air pressure range: First, you need to consult the user manual of the tunnel battery car or the sign on the vehicle to find the correct air pressure range. This range is usually in psi (pounds per square inch) or kPa (kilopascals).
2. Prepare an air compressor: You need an air compressor to inflate. You can do this at a gas station, an auto repair shop or by buying a household pump.
3. Remove the valve cap: connect the barometer to the valve on the vehicle with an adapter. Before connecting, make sure to remove the dust and dirt around the valve.
4. Measure the initial air pressure: measure the current air pressure with a barometer. Insert the connector of the barometer into the valve, wait for a few seconds until the pressure is stable, and read the pressure value on the indicator.
5. Inflate or deflate: If the current air pressure is lower than the recommended range, use the adapter of the inflator to connect to the valve and slowly add air. If the air pressure is too high, gently press the valve stem with a suitable tool to release some air until the required air pressure is reached.
6. Measure the air pressure again: After the inflation or deflation is completed, measure the air pressure with the barometer again to ensure that it is within the recommended range. If fine adjustment is needed, the above steps can be repeated until the required air pressure is reached.
7. Install the bonnet: After adjustment, reinstall the bonnet on the valve to ensure that the valve is in a clean and safe state.
Please note that when adjusting the air pressure, please make sure to use the correct tools and follow the safety operation instructions. If you are not sure or familiar with this process, you'd better consult a professional technician or ask the vehicle manufacturer for advice. The correct air pressure is very important for the safety and performance of the vehicle, so be sure to operate it carefully.
