ENGLISH

CAUTION:

 

Only use genuine Makita batteries.

 

Use of non-genuine Makita batteries, or batteries that 
have been altered, may result in the battery bursting 

causing fires, personal injury and damage. It will also 

void the Makita warranty for the Makita tool and charger.

Tips for maintaining maximum 
battery life

1. 

Charge the battery cartridge before completely 
discharged. Always stop tool operation and 
charge the battery cartridge when you notice 
less tool power.

2. 

Never recharge a fully charged battery cartridge. 
Overcharging shortens the battery service life.

3. 

Charge the battery cartridge with room tempera-
ture at 10 °C - 40 °C (50 °F - 104 °F). Let a hot 
battery cartridge cool down before charging it.

4. 

When not using the battery cartridge, remove 
it from the tool or the charger.

5. 

Charge the battery cartridge if you do not use 
it for a long period (more than six months).
