Ignoring these precautions before each ignition can lead to major troubles. The engine of a mobile stage vehicle is akin to the human heart; any issues with the engine can make the vehicle struggle even on flat roads, and in severe cases, it may become nearly impossible to move. Listen to what the engine repair expert has to remind all drivers.

1. Before operating the mobile stage vehicle, it is essential to inspect the ground beneath the engine for any oil or water stains. If there are oil or water spots on the ground, it is definitely a sign of a leak in the engine, which must be repaired promptly.

2. Check the oil level with the dipstick; this is a daily requirement for stage vehicle drivers.

Check the liquid level of the small water tank's coolant in the mobile stage vehicle. If the engine is severely lacking water, it can lead to overheating at best and "coking" at worst, with serious consequences. Moreover, repairing the vehicle is麻烦, expensive, and time-consuming.

4. Keep an eye on the engine sound during operation for any abnormalities. If you hear any unusual noises, pull over immediately to inspect and identify the cause of the issue.

When the engine dashboard's red light is on, it indicates a fault in the component or system. The stage vehicle must stop and inspect immediately.
