- Power Indicator: Regularly check the 4 LED indicator lights on the battery to monitor the remaining charge during use. This helps in planning work and avoiding unexpected power loss.
- Overload Protection: The battery features built-in overload protection. If the tool stops unexpectedly, it may be due to an overload. Release the trigger, allow the tool and battery to cool, and then resume operation.
- Temperature Protection: If the battery becomes too hot during prolonged use, the internal overheating protection may activate, temporarily shutting down the battery. Allow it to cool down before continuing.
