OPERATIONAL CAUTIONS
Resting the unit after continuous work
(1) The power tool is equipped with a temperature
protection circuit to protect the motor.
Continuous bolt-tightening 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 tightening wood screw 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.
