Why does my tool stop and the battery fuel gauge flash during heavy use?

This occurs when the REDLINK™ Intelligence detects a high-draw or over-current situation. It is a protective feature that shuts down the battery to prevent permanent damage to the cells and the tool’s motor. To resolve this, release the trigger, ensure you are not over-forcing the tool, and resume operation. If the gauge continues to flash, the battery likely requires a full recharge.
