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.

When charging 

When the charging begins, the first (far left) indicating 
lamp begins to flicker. Then, as charging proceeds, the 
other lamps light, one after the other, to indicate the 
battery capacity. 

When using 

When the tool is switched on, the lamps will light to 
indicate the remaining battery capacity. When the tool is 
switched off, the light goes out after approx. 5 seconds. 
When the orange lamp lights up (or flickers) on 
BL1430A or flickers on BL1415NA, the tool stops 
because of little remaining battery capacity (Auto-stop 
mechanism). Charge the battery cartridge at this time or 
use a charged battery cartridge at this time. 
When the tool is used with the battery that has not been 
used for a long time and is switched on, no lamps may 
light up. The tool stops because of little remaining 
battery capacity at this time. For BL1430A only, use 
Makita refreshing adapter to refresh the battery.

The tool stops automatically after the battery capacity 
reaches under 20% on BL1430A or 15% on BL1415NA 
to prevent the lack of fastening torque. Charge the 
battery or use a new fully charged one. 

Battery protection system (BL1415NA) 

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 the following 
conditions: 

 

1. Red indicator 
2. Button 
3. Battery
