ing condition, because it does not have to be
plugged into an electrical outlet.

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 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 battery 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 temperature 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.

Installing or removing battery cartridge
(Fig. 1)
• Always switch off the tool before insertion or
removal of the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while sliding the button on the cartridge.
• To insert the battery cartridge, align the tongue on
the battery cartridge with the groove in the housing
and slip it into place. Always insert it all the way until
it locks in place with a little click. If you can see the

cannot be seen. If not, it may accidentally fall out of
the tool, causing injury to you or someone around
you.
• Do not use force when inserting the battery car-
tridge. If the cartridge does not slide in easily, it is
