FCC caution

Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

Charging

1. Plug the battery charger into the proper AC voltage source. Charging lights will flash slowly 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 charging light color will change from green to blue, and charging will begin. The fast blue flashing light indicates charged condition in 0–80 % and the blue charging light will keep lighting up steadily indicating 80–100 %. The 80 % indication mentioned above is an approximate value. The indication may differ according to battery temperature or battery condition.
4. With the finish of the charge, the charging light will change from a blue one to a green one and the melody sound or buzzer sound (a long beep) comes out to notify completion of charge.
5. After charging, remove the battery cartridge from the charger and unplug the charger.

NOTE: Charging time varies by temperature (10°C (50°F)–40°C (104°F)) that battery cartridge is charged at and conditions of the battery cartridge, such as a battery cartridge which is new or has not been used for a long period of time.

NOTICE: The battery charger is for charging the Makita-battery cartridge. Never use it for other purposes or for other manufacturers’ 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 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 being 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 the charge, the charging light will light up in green and the melody sound preset at the insertion of the 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.

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.
Blue and the red lights will flash alternately for warning in the following cases.

• Trouble on the cooling fan
• Incomplete cooldown of battery, such as being clogged with dust

The battery can be charged in spite of the alternate blue and red 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.
Always keep clean the vent on the charger and battery for cooling.

► 1. Exhaust vent 2. Intake vent
NOTE: The cooling system is in order although no sound of the cooling fan comes out if the blue and red light will not flash.
NOTE: The products should be sent to repair or maintenance if the blue and red lights flash alternately so often.

Wall mounting
