Precautions for heavy truck maintenance

1. Before starting the truck, check whether the water tank is full. In order to avoid high engine water temperature, it is better to use antifreeze, which can also remove scale.
2. Drive the truck to a flat place, and check whether the oil is at the upper limit of the dipstick scale after stopping steadily. At the same time, pay attention not to leak oil at the bottom of the engine.
3. Check whether the oil level of the brake oil is at the middle high position of the oil tank. The oil color should be very clear. If it turns black, replace it as soon as possible.
4. Remember to fill up the glass cleaner. In case of rain on the road, it is very important to clean the glass.
5. Start the engine and listen to the horn for normal sound. Open the wiper and check whether the gear speed is normal.
6. Check the lights, including the headlights, side lights, fog lights, brake lights, license plate lights and reversing lights.
7. Adjust the tire and spare tire pressure.
