NOTE:
• The battery charger is for charging Makita-battery cartridge.
Never use it for other purposes or for other manufacturer’s
batteries.
• When you charge a battery cartridge which is new or has not
been used for a long period of time, it may not accept a full
charge until after discharging it completely and recharging a
couple of times. (Ni-MH battery only)
• If charging light may flash in red color, battery condition is as
below and charging may not start.
– Battery cartridge from just-operated tool or battery cartridge
that has been left in a location exposed to direct sunlight for
a long time.
Changing melody sound of completed charging
1. Insert the battery cartridge into the charging port that you
want to change the melody sound of completed charging. It
brings out the 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 green light remains lit with the red
light going out 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.

– Battery cartridge that has been left for a long time in a location
exposed to cold air.
When the battery cartridge is too hot, charging will begin after the
cooling fan installed in the charger cools the battery cartridge.
Charging will begin after the battery cartridge temperature
reaches the degree at which charging is possible.
• If the charging light flashes alternately in green and 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.
Cooling system
• This charger is equipped with cooling fan for heated battery in
order to enable the battery to prove its own performance. Sound
of cooling air comes out during cooling, which means no trouble
on the charger.
• Yellow light will flash for warning in the following cases.
– Trouble on cooling fan
– Incomplete cool down of battery, such as, being clogged with
dust
The battery can be charged in spite of the yellow warning light.
But the charging time will be longer than usual in this case.
Check the sound of cooling fan, vent on the charger and battery,
which can be sometime clogged with dust.
• The cooling system is in order although no sound of cooling fan
comes out, if the yellow warning light will not flash.
• Always keep clean the vent on charger and battery for cooling.
• The products should be sent to repair or maintenance, if the
yellow warning light will frequently flash.
Conditioning charge
Conditioning charge can extend the life of battery by automatically
searching the optimum charging condition for the batteries in every
situation.
The battery employed in the following conditions repeatedly re-
quires “conditioning charge” to prevent fast wear out. In that case,
yellow light lights up.
1. Recharge of battery with its high temperature
2. Recharge of battery with its low temperature
3. Recharge of full charged battery
4. Over-discharge of battery (continue to discharge battery in
spite of down of power.)
The charging time of such battery is longer than usual.
