Kickback Brake™
When a pinch, stall, or bind‑up event is sensed, the electronic
brake engages with maximum force to quickly stop the wheel,
reduce the movement of the grinder, and shut the grinder
off. The switch will need to be released then depressed to
restart tool.
Power‑OFF™ Overload Protection
The power supply to the motor will be reduced in case of
motor overload. With continued motor overload, the tool will
shut off. The switch will need to be released then depressed

If continued overload shutdowns occur, apply less force/
weight on the tool until the tool will function without the
overload engaging.
