Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts o power to the 
motor to extend tool and battery life. The tool will auto-
matically stop during operation if the tool or battery is 
placed under one of the following conditions:
Overload alert function
The overload alert function may work if the current rises 
sharply due to the operation such as applying too much 
pressure onto a workpiece.
The overload alert function decline the speed of the oscil-
lation and then increases the amplitude of vibration.
In this case, once isolate the application tool from the 
workpiece, then the speed of the oscillation goes back. 
Continue operation with an appropriate load.
Overload protection
When the tool/battery is operated in a manner that 
causes it to draw an abnormally high current, the tool 
stops automatically. In this situation, turn the tool o 
and stop the application that caused the tool to become 
overloaded. Then turn the tool on to restart.
Overheat protection
When the tool/battery is overheated, the tool stops 
automatically. In this situation, let the tool/battery cool 
before turning the tool on again.
Overdischarge protection
When the battery capacity is not enough, the tool stops 
automatically. In this case, remove the battery from the 
tool and charge the battery.
Protection lock function
When the protection system works repeatedly, the tool is locked.
In this situation, the tool does not start even if turning 
the tool o and on. To release the protection lock, 
remove the battery, set it to the battery charger and wait 
until the charging nishes.
Switch action
CAUTION: Before installing the battery car-
tridge into the tool, always check to see that the 
tool is switched o.
