Charging procedure
Make sure power circuit voltage is the same
as that shown on the charger specification
plate.
1 Plug the charger into an appropriate
outlet before inserting battery pack.
2 Insert the battery pack into the charger.
The green (charging) light will blink con-
tinuously indicating that the charging
process has started.
3 The completion of charge will be indicated
by the green light remaining on continu-
ously. The pack is fully charged and may
be used at this time.
4 Disconnect charger from power source
when not in use.
C a u t i o n
Do not probe with conductive objects.
120/230 V AC present at charging ter-
minals. Failure to comply may result in
death or personal injury.
Indicator light operation
The charge is complete (solid green).
Battery is charging (flashing green).
Red, at a fast rate. Replace battery.
Charger detected a weak or damaged
battery. Stop charging battery.
Hot/cold pack delay.
Charger detected a battery that is
excessively hot or cold. It
automatically starts a hot/cold pack
delay, suspending charging until
temperature of battery has
normalized. After this, charger
automatically switches to battery
charging mode.
!
Notice
Battery temperature will increase
during and shortly after use. Batteries
may not accept a full charge if they are
charged immediately after use. Allow the
battery pack to cool to room tempera-
ture before charging for best results.
!
Notice
Vent slots in top and bottom of
charger must not be obstructed.
Do not charge battery when tempera-
ture is below 5 °C (40 °F) or above 40 °C
(104 °F).
Important charging
Notices
Longest life and best performance can be
obtained if the battery is charged when the
air temperature is between 18 and 24 °C
(65 and 75 °F). Do not charge the battery in
an air temperature below 5 °C (40 °F) or
above 41 °C (105 °F). This is important and
will prevent serious damage to the battery.
1 The charger and battery may become
warm to the touch while charging. This is
a normal condition, and does not indicate
a problem.
2 If the battery does not charge properly:
2.1 Check current at receptacle by plug-
ging in a lamp or other appliance.
2.2 Check to see if the receptacle is con-
nected to a light switch which turns
power off when you turn out the
lights.
2.3 Move charger and battery to a loca-
tion where the surrounding air tem-
perature is between approximately
18 to 24 °C (65 to 75° F).
2.4 If charging problems persist, take the
tool, battery and charger to your local
service center.
3 The battery should be recharged when it
fails to produce sufficient power on jobs.
Do not continue to use under these con-
ditions. Follow the charging procedure.
You may also charge a partially used pack
whenever you desire with no adverse af-
fect on the battery.

4 Under certain conditions, with the charger
plugged into the power supply, the ex-
posed charging contacts of the charger
can be shorted by foreign material. For-
eign materials of a conductive nature
such as, but not limited to, steel wool, al-
uminium foil, or any buildup of metallic
particles should be kept away from
charger cavities. Always unplug the
charger from the power supply when
there is no battery in the cavity. Unplug
charger before attempting to clean.
5 Do not freeze or immerse charger in
water or any other liquid.
W a r n i n g
Do not allow any liquid to get inside
charger. Electric shock may result.
To facilitate cooling of battery pack af-
ter use, avoid placing charger or battery
pack in a warm environment such as a
metal shed or an un-insulated trailer.
Failure to comply may result in seri-
ous injury or death.
