CHARGING THE LI-ION BATTERY
Li-ion Battery Pack
NOTE: Your battery pack is not fully
charged at time of purchase. Be sure
to charge the battery before first use.
Remove the battery pack when
the tool is idle for a long time.
Recharge the battery pack once
every 6 months even if the battery
is not in use.
Batteries should be charged in
ambient temperatures between
0°C (32°F) and 40°C (104°F).
Charging outside this range will
result in either less than full
charge or damage to battery pack.
Allow the charger to cool when
charging more than two battery
packs consecutively.
Do not insert your fingers/body
parts into contact area of charger.
Charging the Battery
1. Place charger in a relatively cool
and well-ventilated area.
2. Plug charger into the AC outlet.
CAUTION:
Ensure that the power
source to be utilized conforms to
the power requirement specified
on the product nameplate.
3. Turn the battery upside down and
slide it into the charger while keep-
ing the alignment marks aligned.
Slide forward in the direction of the
arrow. Do not force battery: It
should slide easily into place with
nominal force. Any difficulty doing
so indicates incorrect alignment.
4. If the power lamp (red) does not
light immediately or goes out
soon after the charger is plugged
in, consult a Signature Series au-
thorized dealer.
5. During charging, the charging lamp
(green) will flash. When charging is
complete, an internal electronic
switch will automatically be trig-
gered to prevent overcharging.
– Charging will not start if the
battery pack is warm; for exam-
ple, immediately after heavy-
duty operation. The yellow
standby lamp will flash until the
battery cools down.
6. If the temperature of the battery
pack is 0
o
C (32°F) or less, charg-
ing will take longer to fully charge
the battery pack than standard
charging time. At this low temper-
ature, even when the battery is
fully charged, it will have approxi-
mately 50% of the power of a fully
charged battery at normal opera-
tion temperature.
7. Once battery is fully charged, the
green lamp will light to indicate
the charge has entered into a
trickle charge mode
