Switch lever Electronic function Active Feedback sensing Technology CAUTION: Hold the tool firmly until the rotation stops. The tool electronically detects situations where the wheel or accessory may be at risk to be bound. In such situation, the tool automatically shuts off the power to prevent further rotation of the spindle (this does not prevent kickback). At this time, the indication lamp blinks in red and shows the Active Feedback sensing Technology is working. To restart the tool, switch off the tool first, remove the cause of sudden drop in the rotation speed, and then turn the tool on.
