• If it is started with too little battery
power remaining, the tool may stop
operating without the battery low
warning lamp flashing first. This
indicates that there is too little battery
power remaining to use the tool, and
the battery pack should be charged
before further use.
• If the tool is subject to a sudden load
during use that causes the motor to
lock up, the overdischarge prevention
sensor may be triggered, and the
battery low warning lamp may flash.
The lamp will stop flashing once you
address the cause of the motor’s
locking up and cycle the trigger.

For Appropriate Use of
Battery pack
Li-ion Battery pack
• For optimum battery life, store the Li-
ion battery pack following use without
charging it.
• When charging the battery pack,
confirm that the terminals on the
battery charger are free of foreign
substances such as dust and water
etc. Clean the terminals before
charging the battery pack if any
foreign substances are found on the
terminals.
The life of the battery pack
terminals may be affected by foreign
substances such as dust and water
etc. during operation.
• When battery pack is not in use,
keep it away from other metal objects
like: paper clips, coins, keys, nails,
screws, or other small metal objects
that can make a connection from one
terminal to another.
Shorting the battery terminals
together may cause sparks, burns or
a fire.
• When operating the battery pack,
make sure the work place is well
ventilated.
• When the battery pack is removed
from the main body of the tool,
replace the battery pack cover
immediately in order to prevent dust
or dirt from contaminating the battery
terminals and causing a short circuit.

[Battery Charger]
Charging
Cautions
• If the temperature of the battery pack
falls approximately below −10°C
(14°F), charging will automatically
stop to prevent degradation of the
battery.
•
The ambient temperature range
is between 0°C (32°F) and 40°C
(104°F).
If the battery pack is used when the
battery temperature is below 0°C
(32°F), the tool may fail to function
properly.
• When charging a cool battery pack
(below 0°C (32°F)) in a warm place,
leave the battery pack at the place
and wait for more than one hour to
warm up the battery to the level of the
ambient temperature.
