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.

OPERATING INSTRUCTIONS
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 side of 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 red part on the upper

until the red part 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 cartridge. If the
cartridge does not slide in easily, it is not being inserted
correctly.
