CAUTION:

1. SAVE THESE INSTRUCTIONS – This manual contains important safety and operating instructions for the battery chargers.
2. Before using the battery charger read all instructions and cautionary markings on (1) battery charger, (2) battery, and (3) product using the battery.
3. CAUTION – To reduce the risk of injury, charge only Makita-type rechargeable batteries. Other types of batteries may burst to cause personal injury and damage.
4. Non-rechargeable batteries cannot be charged with this battery charger.
5. Use a power source with the voltage specified on the nameplate of the charger.
6. Do not charge the battery cartridge in presence of flammable liquids or gases.
7. Do not expose the charger to rain or snow.
8. Never carry a charger by a cord or yank it to disconnect from the receptacle.
9. After charging or before attempting any maintenance or cleaning, unplug the charger from the power source. Pull by plug rather than cord whenever disconnecting charger.
10. Make sure the cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress.
11. Do not operate the charger with a damaged cord or plug. If the cord or plug is damaged, ask Makita’s authorized service center to replace it in order to avoid a hazard.
12. Do not operate or disassemble the charger if it has received a sharp blow, been dropped, or otherwise damaged in any way; take it to a qualified serviceman. Incorrect use or reassembly may result in a risk of electric shock or fire.
13. Do not charge the battery cartridge when the room temperature is BELOW 10°C (50°F) or ABOVE 40°C (104°F). When the battery temperature is under 0°C (32°F), charging may not start.
14. Do not attempt to use a step-up transformer, an engine generator, or a DC power receptacle.
15. Do not allow anything to cover or clog the charger vents.

Charging

1. Plug the battery charger into the proper AC voltage source.
   The charging light will flash in green color repeatedly.
2. Insert the battery cartridge into the charger until it stops adjusting to the guide of the charger. The terminal cover of the charger can be opened by inserting and closed by pulling out the battery cartridge.
3. When the battery cartridge is inserted, the red charging light will light up and charging will begin with a preset brief melody sound coming out for assurance as to which sound will come out to notify the completion of charging.
4. With the finish of the charge, the charging light will change from a red one to a green one and the melody sound or buzzer sound (a long beep) comes out to notify completion of the charge.
5. Charging time varies by temperature (10°C (50°F) – 40°C (104°F)) that the battery cartridge is charged at and the conditions of the battery cartridge, such as a battery cartridge that is new or has not been used for a long period of time.
6. After charging, remove the battery cartridge from the charger and unplug the charger.

Changing melody of completed charging

1. Inserting the battery cartridge into the charger 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 inserted and the charge will begin. When a “short beep” mode is selected, no completed charging signals come out. (Silent Mode)
5. With the 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.

 

NOTE:

• The battery charger is for charging the Makita battery cartridge.
  Never use it for other purposes or for other manufacturers’ batteries.
• When you charge a battery cartridge that 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 the charging light may flash in red color, the battery condition is as below, and charging may not start.
  – Battery cartridge from a 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.
  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 a cooling fan for a heated battery in order to enable the battery to prove its own performance. The sound of cooling air comes out during cooling, which means no trouble on the charger.
• The yellow light will flash as a warning in the following cases.
  – Trouble with the 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 the cooling fan, vent on the charger, and battery, which can be sometimes clogged with dust.

•  The cooling system is in order although no sound of the cooling fan comes out if the yellow warning light will not flash.
• Always keep clean the vent on the 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 the battery by automatically searching for the optimum charging condition for the batteries in every situation.
The battery employed in the following conditions repeatedly requires a “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 the battery in spite of down of power.)

The charging time of such a battery is longer than usual.
