ENglIsh
• Do not expose a battery pack or appliance to fire or
excessive temperature. Exposure to fire or temperature
above 265 °F (130 °C) may cause explosion.
• If battery contents come into contact with the skin,
immediately wash area with mild soap and water. If
battery liquid gets into the eye, rinse water over the open
eye for 15 minutes or until irritation ceases. If medical
attention is needed, the battery electrolyte is composed of a
mixture of liquid organic carbonates and lithium salts.
• Contents of opened battery cells may cause
respiratory irritation. Provide fresh air. If symptoms
persist, seek medical attention.
• Battery liquid may be flammable if exposed to spark
or flame.
• Never attempt to open the battery pack for any
reason. If the battery pack case is cracked or
damaged, do not insert into the charger. Do not crush,
drop or damage the battery pack. Do not use a battery pack
or charger that has received a sharp blow, been dropped,
run over or damaged in any way (e.g., pierced with a nail,
hit with a hammer, stepped on). Damaged battery packs
should be returned to the service center for recycling.
Storage Recommendations
The best storage place is one that is cool and dry, away
from direct sunlight and excess heat or cold. Store the fully
charged battery pack out of the charger.
Battery Pack Cleaning Instructions
Dirt and grease may be removed from the exterior of the
battery pack using a cloth or soft non‑metallic brush. Do not
use water or any cleaning solutions.
Fuel Gauge Battery Packs (Fig. B)
Some battery packs include a fuel gauge. When the fuel
gauge button is pressed and held, the LED lights will
indicate the approximate level of charge remaining. This
does not indicate tool functionality and is subject to
variation based on product components, temperature, and
end‑user application.
Transportation

WARNING: Fire hazard. Do not store, carry, or
transport the battery pack so that metal objects
can contact exposed battery terminals. For
example, do not place the battery pack in aprons,
pockets, tool boxes, product kit boxes, drawers, etc.,
with loose nails, screws, keys, coins, hand tools, etc.
When transporting individual battery packs, make
sure that the battery terminals are protected and well
insulated from materials that could contact them and
cause a short circuit. NOTE: Li-ion battery packs should
not be put in checked baggage on airplanes and must
be properly protected from short circuits if they are in
carry-on baggage.
shipping the D WALT FlEXVolT™ Battery pack
e
The D WALT FLEXVOLT™ battery pack has a battery cap that
e
should be used when shipping the battery pack.
24
Attach the cap to the battery pack to ready it for shipping.
This converts the battery pack to three separate 20V
batteries. The three batteries have the Watt hour rating
labeled "Shipping" on the battery pack. If shipping without
the cap or in a tool, the pack is one battery at the Watt hour
rating labeled "Use".
Example battery pack label:
USE: 120 Wh SHIPPING: 3 x 40 Wh
In this example, the battery pack is three batteries with
40 Watt hours each when using the cap. Otherwise, the
battery pack is one battery with 120 Watt hours.
Important Safety Instructions for All
Battery Chargers

WARNING: Read all safety warnings, instructions,
and cautionary markings for the battery pack,
charger and product. Failure to follow the
warnings and instructions may result in electric
shock, fire and/or serious injury.
• DO NOT attempt to charge the battery pack with
any chargers other than a D
chargers and battery packs are specifically designed to
work together.
• These chargers are not intended for any uses other
than charging D WALT rechargeable battery packs.
e
Charging other types of battery packs may cause them to
overheat and burst, resulting in personal injury, property
damage, fire, electric shock or electrocution.
• Do not expose the charger to rain or snow.
Do not allow water or any liquid to enter charger.
•
• Pull by the plug rather than the cord when
disconnecting the charger. This will reduce the risk of
damage to the electric plug and cord.
Make sure that the cord is located so that it will not
•
be stepped on, tripped over or otherwise subjected to
damage or stress.
• 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 for
•
safety. The smaller the gauge number of the wire, the
greater the capacity of the cable, that is, 16 gauge has
more capacity than 18 gauge. An undersized cord will
cause a drop in line voltage resulting in loss of power and
overheating. When using more than one extension to
make up the total length, be sure each individual extension
contains at least the minimum wire size. The following
