Makita 1051D Instruction Manual page 10

CAUTION:
*The high capacity battery charger Model DC1411 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 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 high capacity battery charger.
*If the charging light flashes alternately in green and red color, a problem exists and charg-
ing is not possible. The terminals on the charger or battery cartridge are clogged with
dust or the battery cartridge is worn out or damaged.
*If you wish to charge two battery cartridge, allow 15 minutes between charging on the
high capacity battery charger.
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.
