️Safety Notice:

Connect the positive and negative terminals correctly. The green light indicates proper connection.

Incorrect connection will trigger a red warning light and buzzer as a safety alert.

Use the air pump for no more than 6 minutes continuously to avoid overheating.

Light vapor during operation is normal due to the heating of the internal lubricating fluid.

Do not use in high-temperature, flammable, or poorly ventilated areas.

If you notice excessive heat, unusual odor, continuous alarms, or malfunction, stop use immediately and contact customer support.

Operation Tips:

- Ensure the unit is fully charged before use.

- Follow the step-by-step instructions in the manual to avoid incorrect operation.

- If the unit does not turn on, check the battery level and ensure all connections are secure.

- When using the air pump function in cold weather, visible vapor (mist) may appear. This is **not smoke** and is a normal physical phenomenon caused by the temperature difference between the unit's internal operation and the cold ambient air. Faint oil vapor during initial use is also harmless and will dissipate quickly.
