Tool / battery protection system
The tool is equipped with a tool/battery protection sys- tem. This system automatically cuts off 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 protection
When the battery is operated in a manner that causes it to draw an abnormally high current, the tool
automati- cally stops. In this situation, turn the tool off and stop the application that caused the tool to
become overloaded. Then turn the tool on to restart.
Overheat protection
When the battery is overheated, the tool stops automat- ically. In this case, let the tool and 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.
If the battery cannot be charged, check the following:
• contact voltage
• makes good contact with the charger contacts
To make sure that the lithium-ion rechargeable battery will last longer, you must recharge it in time.
You must recharge the battery when you notice that the power of the cordless tool is decreasing.
