• Do not use an extension cord unless it is absolutely
necessary. Use of improper extension cord could result in
risk of fire, electric shock or electrocution.
• When operating a charger outdoors, always provide
a dry location and use an extension cord suitable
for outdoor use. Use of a cord suitable for outdoor use
reduces the risk of electric shock.
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.

• 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
vehicular charger.
• 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)
nOTE: To ensure maximum performance and life of Li‑Ion
battery packs, charge the battery pack fully before first use.
nOTE: Refer to the label near indicator light(s) on charger for
on/off and blink patterns. Older chargers may have additional

information and/or may not have a yellow indicator light,
being equipped with only a single red indicator light.
1. Plug the charger into an appropriate outlet before
inserting battery pack.
2. Insert and fully seat battery pack. The left indicator light
will continuously blink red to indicate that the charging
process has started. For two‑stage chargers, this is
indicative of stage 1 charging during which the battery
pack is charged to a majority of its capacity.
3. Charging is complete for a single‑stage charger when the
left indicator light remains continuously red and the right
indicator light stays unlit. For a two‑stage charger, the
left indicator light remains continuously red and the right
indicator light continuously blinks red to indicate stage
2 charging during which the battery pack is topped off to
its full capacity. Stage 2 charging is complete when both
indicator lights remain continuously red. When charging
is complete, the battery pack may be removed and used,
or left in the charger.
The charger will not charge a faulty battery pack. The charger
refusing to light could indicate a problem with the charger
or a faulty battery pack. Discontinue use and take both to an
authorized service center.

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
battery pack.
The hot/cold pack delay will be indicated by the red light(s)
continuing to blink but with the yellow light continuously
ON. Once the battery pack has reached an appropriate
temperature, the yellow light will turn OFF and the charger
will resume the charging procedure.
Fan Cooled Chargers
Some chargers are equipped with an internal fan designed
to cool the battery pack. The fan will turn on automatically
when the battery pack needs to be cooled.
Never operate the charger if the fan does not operate
properly or if ventilation slots are blocked. Do not permit
foreign objects to enter the interior of the charger.
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
