NOTICE:
The battery charger is for charging Makita-battery cartridge. Never use it for other purposes or
for other manufacturer's batteries.
NOTE: If the charging light flashes slowly in blue color, charging may not start due to the condition of the battery
cartridge as below:
— Battery cartridge from just-operated tool or battery cartridge that has been left in a location exposed to direct
sunlight for a long time.
— Battery cartridge that has been left for a long time in a location exposed to cold air.
NOTE: When the battery cartridge is too hot, charging does not begin until the battery cartridge temperature
reaches the degree at which charging is possible.
NOTE: If the charging light changes to red color, charging is not possible. The terminals on the charger or battery
cartridge are clogged with dust or the battery cartridge is worn out or damaged.
Changing melody upon completion of charging
1. Inserting the battery cartridge into charger brings out last preset brief melody sound of completed charging.
2. Removing and re-inserting it within five seconds after this action makes the melody sound change.
3. Every time removing and re-inserting it within another five seconds after this, the melody sound changes in
order.
4. When the desired melody sound comes out, leave the battery cartridge being inserted and the charge will
begin. When a "short beep" mode is selected, no completed charging signals comes out. (Silent Mode)
5. With finish of charge, the charging light will light up in green and the melody sound preset at the insertion of
battery cartridge or buzzer sound (a long beep) comes out to notify completion of charge. (In selected silent
mode, no sounds come out.)
6. Preset melody sound remains stored even when the charger is unplugged.
