Trickle charge (Maintenance charge)
If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the charger will
switch into its "trickle charge (maintenance charge)" mode and keep the battery cartridge fresh and fully charged.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely discharged.
Always stop tool operation and charge the battery cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room temperature at 10°C – 40°C (50°F – 104°F).
Let a hot battery cartridge cool down by inserting it into the charger.
4. Charge the Nickel Metal Hydride battery cartridge when you do not use it for more than six months.
NOTE:
• The battery charger is for charging Makita-battery cartridge. Never use it for other purposes or for other manufac-
turer's batteries.
• When you charge a new battery cartridge or a battery cartridge which has not been used for a long period of time, it
may not accept a full charge. This is a normal condition and does not indicate a problem. You can recharge the bat-
tery cartridge fully after discharging it completely and recharging a couple of times.
• If you charge a battery cartridge from a just-operated tool or battery cartridge which has been left in a location
exposed to direct sunlight for a long time, the charging light may flash in red color. If this occurs, wait for a while.
Charging will begin after the battery cartridge is cooled by the cooling fan installed in the charger. When the temper-
ature on battery is more than approx. 70°C, two charging lights may flash in red color, and when approx. 50°C –
70°C, one charging light in red color.
• 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.
• Any of the following conditions indicates damage to the charger and/or battery cartridge. Ask your Makita Authorized
or Factory Service Center to check them.
1) The charging light does not flash (green) when the battery charger is plugged into a power source.
2) The charging light does not light up or flash (red) when the battery is inserted in the charger port.
3) Charging is not completed at even more than two hours after red light comes ON at start of charging.
Refresh charging
• Refreshing adapter (optional accessory) can refresh an inactive battery cartridge.
• Refresh charging should be done once a week.
• When you charge a new battery cartridge or a battery cartridge that has not been used for a long time, it may not
accept a full charge. In this case, refresh charging must be done. The battery cartridge may decrease the tool perfor-
mance, because the chemical substance of the battery cartridge is inactive.
Checking the remaining battery capacity (Fig. 3)
When charging
When the charging begins, the first (far left) indicator lamp begins to flicker. Then, as charging proceeds, the other
lamps light, one after the other, to indicate the battery capacity.
When using
When the tool is switched on, the lamps will light to indicate the remaining battery capacity. When the tool is switched
off, the light goes out automatically.
If the battery has not been used for a long time, or is needed refresh charging, the (C) lamp begins to flicker. Use Mak-
ita refreshing adapter to refresh the battery.
Installing or removing bit
Important:
Always be sure that the tool is switched off and the battery cartridge is removed before installing or removing the bit.
Use only the driver bit or socket bit shown in the figure below.
Do not use any other driver bit or socket bit.
To install the bit, pull the sleeve in the direction of the arrow and insert the bit into the sleeve as far as it will go. Then
release the sleeve to secure the bit. (Fig. 4)
To remove the bit, pull the sleeve in the direction of the arrow and pull the bit out firmly.
