5. Safety Information
To ensure safe operation and prevent damage to the inverter or connected devices, please observe the following safety guidelines:
- Do not exceed the maximum output power of 220W. Overloading the inverter can cause damage and pose a fire hazard.
- Ensure proper ventilation. The built-in cooling fan requires unobstructed airflow to prevent overheating.
- This inverter is equipped with multiple protection functions: short circuit protection, over-current protection, low voltage protection, overheat protection, over-discharge protection, and overload protection.
- Do not expose the inverter to water, rain, or excessive moisture.
- Keep out of reach of children.
- Use only with compatible Milwaukee 18V batteries.
- If the inverter indicates a fault (e.g., flashing red or yellow lights), disconnect the battery and connected devices immediately. Refer to the troubleshooting section.

6. Maintenance
To ensure the longevity and optimal performance of your Hisecren Power Inverter, follow these maintenance guidelines:
- Cleaning: Regularly wipe the exterior of the inverter with a dry, soft cloth. Do not use harsh chemicals or abrasive cleaners. Ensure the cooling fan vents are free from dust and debris.
- Storage: When not in use for extended periods, store the inverter in a cool, dry place away from direct sunlight and extreme temperatures. Remove the battery before storage.
- Battery Care: Always use fully charged batteries for optimal performance. Avoid completely draining batteries, as this can reduce their lifespan.
7. Troubleshooting
If you encounter issues with your power inverter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
