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.
