REACTIVE FORCE CONTROL
This product is equipped with a Reactive Force Control
(RFC) feature that reduces jerking of the tool body.
If the tool bit is suddenly overburdened, any jerking of the
tool body is reduced by activation of the slip clutch or by
stopping of the motor by the sensor built into the tool body.
If the motor is stopped because of overburdening detection
by the controller, the RFC indicator lamp will blink while the
switch is pulled.
