charger and battery pack to an authorized service center

NOTE: Refer to label near charging light(s) on charger for
NOTE: To remove the battery pack, some chargers
require the battery pack release button to bepressed.
Hot/Cold Pack Delay
When the charger detects a battery pack that is too hot
or too cold, it automatically starts a Hot/Cold Pack Delay,
suspending charging until the battery pack has reached an
appropriate temperature. The charger then automatically
switches to the pack charging mode. This feature ensures
maximum battery packlife.
A cold battery pack may charge at a slower rate than a warm
The hot/cold pack delay will be indicated by the green
light(s) continuing to blink but with the red light
continuously ON. Once the battery pack has reached an
appropriate temperature, the red light will turn OFF and the
charger will resume the chargingprocedure.
Electronic Protection System
Li-Ion tools are designed with an Electronic Protection
System that will protect the battery pack against overloading,
overheating or deep discharge. The tool will automatically
turn off and the battery pack will need to berecharged.
Important Charging Notes
1. Longest life and best performance can be obtained if
the battery pack is charged when the air temperature
is between 65°F – 75°F (18° C– 24°C). DO NOT charge
when the battery pack is below +40°F (+4.5°C), or
above +104°F (+40°C). This is important and will
prevent serious damage to the batterypack.
2. The charger and battery pack may become warm to the
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 operation of 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
c. If charging problems persist, take the tool, battery
pack and charger to your local servicecenter.
4. You may charge a partially used pack whenever you
desire with no adverse effect on the batterypack.
Charger Cleaning Instructions
WARNING:Shock hazard. Disconnectthe charger
from the AC outlet before cleaning. Dirt and grease
may be removed from the exterior of the charger using
a cloth or soft non‑metallic brush. Do not use water or
any cleaningsolutions.
An extension cord must have adequate wire size
(AWG or American Wire Gauge) for safety. The smaller
the gauge number of the wire, the heavier the cord and
thus the greater its capacity. An undersized cord will
cause a drop in line voltage resulting in loss of power and
overheating. The following table shows the correct size
to use depending on total length of all extension cords
plugged together, and nameplate ampere rating. If in
doubt, use the next heaviergauge.
Minimum Gauge for Cord Sets

Do not place any object on top of the charger or place
the charger on a soft surface that might block the
ventilation slots and result in excessive internal heat.
Place the charger in a position away from any heat source.
The charger is ventilated through slots in the top and the
bottom of thehousing.
Do not operate the charger with a damaged cord
orplug. Have them replacedimmediately.
Do not operate the charger if it has received a sharp
blow, been dropped or otherwise damaged in any
way. Take it to an authorized servicecenter.
Do not disassemble the charger; take it to an
authorized service center when service or repair
is required. Incorrect reassembly may result in a risk of
electric shock, electrocution orfire.
The charger is designed to operate on standard
120V household electrical power. Do not attempt to
use it on any other voltage. This does not apply to the
Foreign materials of a conductive nature, such as, but
not limited to, grinding dust, metal chips, steel wool,
aluminum foil or any buildup of metallic particles
should be kept away from the charger cavities and
ventilation slots.
Always unplug the charger from the power supply
when there is no battery pack in thecavity.
Charging a Battery (Fig.C, D)
1. Plug the charger into an appropriate outlet.
2. Insert and fully seat battery pack
. Green charging
light(s) will continuously blink whilecharging.
3. Charging is complete when the green charging light(s)
remain(s) continuously ON. Battery pack can be left in
charger or removed.
WARNING: Only charge batteries in air temperature
over 40° F (4.5° C) and below 104° F (+40°C).
4. Charger will not charge a faulty battery pack, which may
be indicated by the charging light(s) staying OFF. Take
