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

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

If the tool is overloaded by entangled weeds or other 
debris, 

 and the middle indicators start blinking and 

the tool automatically 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 for tool or 

battery

There are two types of overheating; tool overheating 

and battery overheating. When the tool over heating 

occurs, all speed indicators blink. When the battery over 

heating occurs, 

 indicator blinks.

If the overheating occurs, the tool stops automatically. 

Let the tool and/or battery cool down before turning the 

tool on again.

Overdischarge protection

When the battery capacity becomes low, the tool stops 

automatically and 

 indicator blinks.

If the tool does not operate even when the switches are 

operated, remove the batteries from the tool and charge 

the batteries.
