OPERATIONAL CAUTIONS

Resting the unit after continuous work
(1) The power tool is equipped with a temperature protection circuit to protect the motor.
Continuous work may cause the temperature of the unit to rise, activating the temperature
protection circuit and automatically stopping operation.
If this happens, allow the power tool to cool before resuming use.
(2) After use for continuous works, rest the unit for 15 minutes or so when replacing the battery.
The temperature of the motor, switch, etc., will rise if the work is started again immediately
after battery replacement, eventually resulting in burnout.

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, this is indicated by blinking of the remaining
battery lamp while the switch is pulled. (Fig. 28)
Because the RFC feature may not activate or its performance
may be insuffi cient depending on the working environment
and conditions, be careful not to suddenly overburden the
tool bit while operating.
