• Attach the battery pack by sliding until
EN
the yellow and red labels are no longer
visible, and check that it does not fall out
of place.
- Failure to do so may result in scalding.
• The usage temperature range for lithium
ion battery packs is 0 to 40 degrees.
- Use of battery packs cooled to below
zero, such as in colder northern areas,
may result in abnormal operation of the
device. In such cases, leave the battery
pack in a location of 10 degrees or
more for one hour or more before use,
and only use the device after the
battery pack has warmed up.
[Battery Charger]
Charging
CAUTION:
1) If the temperature of the battery pack
falls approximately below −10°C
(14°F), charging will automatically
stop to prevent degradation of the
battery.
2) 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.
3) Use the charger at temperatures
between 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
between the temperatures of the
battery and the charging location.)
4) 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.
5) Cool down the charger when charging
more than two battery packs consecu-
tively.
6) Do not insert your fingers into contact
hole, when holding charger or any
other occasions.
7) Unplug the charger when not in use.
8) Store the charger between 0 and 40
degrees, and charge the battery pack
at a temperature close to the storage
temperature.
• If the battery pack is charged while at
a temperature below 0 degrees, a full
charge will give only around 50% of a
normal charge. Commence charging
after 1 hour or more at the prescribed
temperature.
9) Do not charge in a poorly ventilated
place.
10) Do not cover the battery pack or
charger with a cloth or the like while
charging is in progress.
NOTE:
Your battery pack is not fully charged at
the time of purchase. Be sure to charge
the battery before use.
How to charge
1. Plug the charger into the AC outlet.
NOTE:
Sparks may be produced when the plug
is inserted into the AC power supply,
but this is not a problem in terms of
safety.
2. Connect the battery pack firmly into the
charger.
(1) Line up the alignment marks and
place the battery onto the dock on
the charger.
NOTE:
Not all battery packs display the
alignment mark (Q) (on page 2).
(2) Slide forward in the direction of the
arrow. [Fig.10
3. During charging, the charging lamp will
be lit. When charging is completed, an
internal electronic switch will automati-
cally be triggered to prevent overcharg-
ing.
• Charging will not start if the battery
pack is hot (for example, immediately
after heavy-duty operation).
The orange standby lamp will be
flashing until the battery cools down.
Charging will then begin automatically.
