CAUTION: 

• 

Always switch off the tool before installing or 
removing of the battery cartridge. 

• 

Hold the tool and the battery cartridge firmly 
when installing or removing battery cartridge.

 

Failure to hold the tool and the battery cartridge 
firmly may cause them to slip off your hands and 
result in damage to the tool and battery cartridge 
and a personal injury. 

To remove the battery cartridge, slide it from the tool 
while sliding the button on the front of the cartridge. 
To install the battery cartridge, align the tongue on the 
battery cartridge with the groove in the housing and slip 
it into place. Insert it all the way until it locks in place 
with a little click. If you can see the red indicator on the 
upper side of the button, it is not locked completely. 

 

CAUTION: 

• 

Always install the battery cartridge fully until the 
red indicator cannot be seen. If not, it may 
accidentally fall out of the tool, causing injury to 
you or someone around you. 

• 

Do not install the battery cartridge forcibly. If the 
cartridge does not slide in easily, it is not being 
inserted correctly. 

Battery protection system 

The tool is equipped with a battery protection system. 
This system automatically cuts off power to the motor to 
extend battery life. 
The tool will automatically stop during operation if the 
tool and/or battery are placed under one of the following 
conditions: 

 
 
 

• 

Overloaded: 

The tool is operated in a manner that causes 
it to draw an abnormally high current. 
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. 
If the tool does not start, the battery is 
overheated. In this situation, let the battery 
cool before turning the tool on again. 

• 

Low battery voltage: 

The remaining battery capacity is too low 
and the tool will not operate. In this situation, 
remove and recharge the battery. 

 

NOTE: 

The overheat protection works only with a battery 
cartridge with a star mark.
