To avoid electric shock and electrical fires,
never use an extension cord that is damaged or does not
meet the following requirements:
• The cord has pins on line plug that are similar in size
and shape to those of the plug on the charger.
• The cord is rated as “W” or “W-A” if being used out-
doors.
• The cord has sufficient wire thickness (16 AWG below
50′/14 AWG 50′-100′). If the wire thickness is too small,
the cord may overheat, melting the cord’s insulation or
causing nearby objects to ignite.
Do not attempt to use a step-up trans-
former, an engine generator or DC power receptacle.
4. Insert the battery cartridge so that the plus and minus
terminals on the battery cartridge are on the same
sides as their respective markings on the battery
charger. Insert the cartridge fully into the port so that
it rests on the charger port floor.
5. When the battery cartridge is inserted, the charging
light color will change from green to red and charging
will begin. The charging light will remain lit steadily dur-
ing charging. When charging is completed, the
charging light color will change from red to green.
NOTE! Charging time will be approximately one hour.
Charge only Makita type batteries. Other
types of batteries may burst causing personal injury.
6. After charging, unplug the charger from the power
source. Always cover the battery terminals with the
battery cover when the batter cartridge is not used.
Important Charging Notes
1. 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.
2. If you charge a battery cartridge from a just-oper-
ated tool or a battery cartridge which has been left in
a location exposed to direct sunlight or heat 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 cools. The battery cartridge will
cool faster if you remove the battery cartridge from the
battery charger.
3. If the charging light flashes alternately in green and red
color, a problem exists and 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.
4. If you wish to charge two battery cartridges, allow
15 minutes between chargings on the battery charger.
