[Battery Pack]
For Appropriate Use of
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 for-
eign substances are found on the
terminals.
The life of the battery pack terminals
may be affected by foreign sub-
stances 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 ven-
tilated.
• 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 con-
taminating the battery terminals and
causing a short circuit.
Battery Pack Life
The rechargeable batteries have a
limited life. If the operation time be-
comes extremely short after recharg-
ing, replace the battery pack with a
new one.
Battery Recycling
ATTENTION:
For environmental protection and
recycling of materials, be sure that
it is disposed of at an officially as-
signed location, if there is one in
your country.
[Battery Charger]
Charging
Cautions
• If the temperature of the battery
pack falls approximately below
−10°C (14°F), charging will auto-
matically stop to prevent degrada-
tion of the battery.
• The ambient temperature range is be-
tween 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.
• Use the charger at temperatures be-
tween 0°C and 40°C, and charge the
battery at a temperature similar to that
of the battery itself. (There should be
no more than a 15°C difference be-
tween the temperatures of the battery
and the charging location.)
• 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.
• Cool down the charger when
charging more than two battery
packs consecutively.
• Do not insert your fingers into contact
hole, when holding charger or any
other occasions.
Storage
Do not store the dust collection cup
in a compressed position. If kept in
a compressed position, it may be
impossible to return to the original
shape.
