ABOUT REMAINING BATTERY INDICATOR
You can check the battery’s remaining capacity by
pressing the remaining battery indicator switch to light the
indicator lamp. (Fig. 29, Table 6)
The indicator will shut off approximately 3 seconds after
the remaining battery indicator switch is pressed.
It is best to use the remaining battery indicator as a
guide since there are slight diff erences such as ambient
temperature and the condition of the battery.
Also, the remaining battery indicator may vary from those
equipped to a tool or charger.

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.
