Important Safety Instructions For All Battery Chargers - DeWalt DCS7485 Manual De Instrucciones

NEVER force the battery pack into the charger. DO NOT modify the battery pack in any
•
way to fit into a non-compatible charger as battery pack may rupture causing serious
personal injury. Consult the chart at the end of this manual for compatibility of batteries
and chargers.
• Charge the battery packs only in designated D
• DO NOT splash or immerse in water or other liquids.
• Do not store or use the tool and battery pack in locations where the temperature may
reach or exceed 104 °F (40 °C) (such as outside sheds or metal buildings in summer). For
best life store battery packs in a cool, dry location.
NOTE: Do not store the battery packs in a tool with the trigger switch locked on. Never
tape the trigger switch in the ON position.
• Do not incinerate the battery pack even if it is severely damaged or is completely worn
out. The battery pack can explode in a fire. Toxic fumes and materials are created when lithium
ion battery packs are burned.
• 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.

WARNING: Burn hazard. Battery liquid may be flammable if exposed to spark or flame.

WARNING: Fire hazard. 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.
Transportation

WARNING: Fire hazard. Do not store or carry 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, etc.
Transporting batteries can possibly cause fires if the battery terminals inadvertently
come in contact with conductive materials such as keys, coins, hand tools and the
like. The US Department of Transportation Hazardous Material Regulations (HMR) actually
prohibit transporting batteries in commerce or on airplanes in carry-on baggage UNLESS
they are properly protected from short circuits. So 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.
Shipping the D WALT FLEXVOLT™ Battery
e
The D WALT FLEXVOLT™ battery has two modes: Use and Shipping.
e
Use Mode: When the FLEXVOLT™ battery stands alone or is in a D
will operate as a 20V Max* battery. When the FLEXVOLT™ battery is in a 60V Max* or a 120V Max*
(two 60V Max* batteries) product, it will operate as a 60V Max* battery.
Shipping Mode: When the cap is attached to the FLEXVOLT™
battery, the battery is in Shipping Mode. Strings of cells are
electrically disconnected within the pack resulting in three
batteries with a lower watt hour (Wh) rating as compared to one
battery with a higher Watt hour rating. This increased quantity
of three batteries with the lower watt hour rating can exempt the pack from certain shipping
regulations that are imposed upon the higher Watt hour batteries.
The battery label indicates two Watt Hour Ratings (see example). Depending on how the battery
is shipped, the appropriate Whr rating must be used to determine the applicable shipping
requirements. If utilizing the shipping cap, the pack will be considered 3 batteries at the Whr
indicated for "Shipping". If shipping without the cap or in a tool, the pack will be considered one
battery at the Watt hour rating indicated next to "Use".
example of Use and Shipping label marking
USE: 120 Wh Shipping: 3 x 40 Wh
Transport Wh rating indicates 3 x 40 Wh, meaning 3 batteries of 40 Watt hours each. The Use Wh
rating indicates 120 Watt hour (1 battery implied).
Fuel Gauge Battery Packs (Fig. B)
Some D WALT battery packs include a fuel gauge which consists of three green LED lights that
e
indicate the level of charge remaining in the battery pack.
The fuel gauge is an indication of approximate levels of charge remaining in the battery pack
according to the following indicators:

To actuate the fuel gauge, press and hold the fuel gauge button (26). A combination of the three
green LED lights will illuminate designating the level of charge left. When the level of charge in
the battery is below the usable limit, the fuel gauge will not illuminate and the battery will need
to be recharged.

NOTE: The fuel gauge is only an indication of the charge left on the battery pack. It does not
indicate tool functionality and is subject to variation based on product components, temperature
and end-user application.

The RBRC® Seal
The RBRC® (Rechargeable Battery Recycling Corporation) Seal on the nickel
cadmium, nickel metal hydride or lithium-ionbatteries (or battery packs)
indicates that the costs to recycle these batteries (or battery packs) at the end
of their useful life have already been paid by D
to place spent nickel cadmium, nickel metal hydride or lithium-ion batteries
in the trash or municipal solid waste stream and the Call 2 Recycle® program provides an
environmentally conscious alternative.
Call 2 Recycle, Inc., in cooperation with D WALT and other battery users, has established the
e
program in the United States and Canada to facilitate the collection of spent nickel cadmium,
nickel metal hydride or lithium-ion batteries. Help protect our environment and conserve natural
resources by returning the spent nickel cadmium, nickel metal hydride or lithium-ion batteries to
an authorized D WALT service center or to your local retailer for recycling. You may also contact
e
your local recycling center for information on where to drop off the spent battery. RBRC® is a

Important Safety Instructions for All Battery Chargers


WARNING: Read all safety warnings and all instructions for the battery pack,
charger and power tool. 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 the ones in
this manual. The charger and battery pack are specifically designed to work together.
• These chargers are not intended for any uses other than charging D
rechargeable batteries. Any other uses may result in risk of fire, electric shock or electrocution.
• Do not expose the charger to rain or snow.
• 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 (AWG or American Wire Gauge) 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 table shows the correct size to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The lower the gauge number, the heavier the cord.

• 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.
