cartridge 
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. 
Tool / battery protection system 
The tool is equipped with
a tool/batteryprotection system. This system 
automatically cuts off power to the motor to extend tool 
and battery life. The tool will automatically 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 
automatically stops without any indication. 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
automatically. In this situation, let the 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. 
NOTE: Overload protection will work only with 
batteries with star marking.

Indicating the remaining battery 
capacity 
►Fig.3: 1. Battery indicator 
When you pull the switch
trigger, the LED display shows
the remaining battery capacity. The remaining battery 
capacity is shown as the following table. 
 
NOTE: When the LED display
 goes off, the tool
 is turned off to save the battery 
power. To check the remaining battery capacity, 
slightly pull the switch trigger. 
NOTE: The LED display goes
 off approximately one
 minute after releasing the switch trigger. 
NOTE: When the LED display
 lights up and the
 tool stops even with a recharged 
battery cartridge, cool down the tool fully. If the status 
will not change, stop using and have the tool repaired 
by a Makita local service center. 
NOTE: When the tool is
 overheated, the light
 blinks for one minute as shown in the 
table below, and then the LED display
 goes off. In this
 case, cool down the
 tool before operating again.
