Note:
• It may take twice the above charging time to the maximum because of the optional charging selected according to the temperature
(10°C (50°F) – 40°C (104°F)), conditions of battery cartridge and maintenance charge.
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.
– 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. Charg-
ing will begin after the battery cartridge temperature reaches the degree at which charging is possible.
• When charging the battery cartridge with a hot charger, the charging lamp may flash in red. After the charger is cooled, charging starts.
• If the charging light flashes alternately in green and red color, or flashes in green color when the battery cartridge is inserted, a problem
exists and charging is not possible. The terminals on the charger are clogged with dust or the Makita battery cartridge is worn out or the
battery of automobile is out of order.
• When the battery of automobile works out of order, the charge lamp does not light on even if the charger is plugged into the automobile
cigarette lighter socket.
• When the remaining automobile battery capacity gets small, stumble down acceleration pedal and charge the battery cartridge while
stumbling down. After completion of charging, be sure to unplug the charger from the automobile socket.
• When charging some battery cartridges successively, the charging time may get longer.
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, 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 sit-
uation.
The battery employed in the following conditions repeatedly requires “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.
