1. Plug the charger into an appropriate
outlet before inserting the battery pack.
2. Insert the battery pack into the charger.
3. The green LED will flash
indicating that the battery is being
charged.
4. The completion of charge
is indicated by the green LED
remaining on continuously. The
pack is fully charged and may
be used at this time or left on the
charger.
Recharge discharged batteries as soon
as possible after use or battery life may
be greatly diminished.
CHARGER DIAGNOSTICS
This charger is designed to detect certain
problems that can arise with the battery packs
or the power source. Problems are indicated
by one LED flashing in different patterns.
BAD BATTERY
The charger can detect a weak
or damaged battery. The red LED
flashes in the pattern indicated on the
label. If you see this bad battery blink
pattern, do not continue to charge the
battery. Return it to a service center
or a collection site for recycling.
HOT/COLD PACK DELAY
When the charger detects a battery
that is excessively hot or excessively
cold, it automatically starts a Hot/Cold
Pack Delay, suspending charging
until the battery has normalized.
After this happens, the charger
automatically switches to the Pack
Charging mode. This feature ensures
maximum battery life. The red LED
flashes in the pattern indicated on
the label when the hot / cold pack
delay is detected.
IMPORTANT CHARGING NOTES
1. Longest life and best performance can
be obtained if the battery pack is charged
when the air temperature is between 60°F
and 80°F (16°- 27°C). DO NOT charge
the battery pack in an air temperature
below +40°F (+4.5°C), or above +105°F
(+40.5°C). This is important and will prevent
serious damage to the battery pack.
2. The charger and battery pack may
become warm to touch while charging.
This is a normal condition, and does
not indicate a problem. To facilitate the
cooling of the battery pack after use, avoid
placing the charger or battery pack in
a warm environment such as in a metal
shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check current at receptacle by
plugging in a lamp or other appliance
b. Check to see if receptacle is connected
to a light switch which turns power off
when you turn out the lights.
c. Move charger and battery pack
to a location where the surrounding
air temperature is approximately 60°F
- 80°F (16° - 27°C).
d. If charging problems persist, take the
tool, battery pack and charger to your
local service center.
4. The battery pack should be recharged
when it fails to produce sufficient power
on jobs which were easily done previously.
DO NOT CONTINUE to use under these
conditions. Follow the charging procedure.
You may also charge a partially used pack
whenever you desire with no adverse
affect on the battery pack.
5. Foreign materials of a conductive nature
such as, but not limited to, steel wool,
aluminum 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
pack in the cavity. Unplug charger before
attempting to clean.
6. Do not freeze or immerse charger in
water or any other liquid.
WARNING:
SHOCK HAZARD
.
Do not allow any liquid to get inside
charger.
NEVER ATTEMPT TO OPEN THE
BATTERY PACK FOR ANY REASON. IF
THE PLASTIC HOUSING OF THE BATTERY
PACK BREAKS OR CRACKS, RETURN TO
A SERVICE CENTER FOR RECYCLING.

STATE OF CHARGE
INDICATOR- FIGURE A
The side of the battery is equipped with a state
of charge indicator. This can be used to display
the current level of charge in the battery during
use and during charging. It does not indicate
tool functionality and is subject to variation
based on product components, temperature
and end-user application.
CHECKING STATE OF CHARGE DURING USE:
• Press the state of charge indicator
button (
A1
).
• The three LED’s (
A2
) will illuminate
indicating the percent of charge in the
battery. See chart in
figure A
.
• If LED light does not lluminate, charge
battery.
NOTE:
This battery is designed to not
operate when a charge below 20% of
its capacity is reached. After the battery
charge is depleted, the tool will not operate
until after the battery has been recharged.
