DeWalt DCS7485 Instruction Manual page 7

Do not operate the charger with a damaged cord or plug.
•
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.
• Disconnect the charger from the outlet before attempting any cleaning. This will reduce
the risk of electric shock. Removing the battery pack will not reduce this risk.
• NEVER attempt to connect 2 chargers together.
• 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.

WARNING: Shock hazard. Do not allow any liquid to get inside the charger. Electric shock
may result.

WARNING: Burn hazard. Do not submerge the battery pack in any liquid or allow any liquid
to enter the battery pack. 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.

CAUTION: Burn hazard. To reduce the risk of injury, charge only D
battery packs. Other types of batteries may overheat and burst resulting in personal injury
and property damage.

CAUTION: When battery pack in not in use, keep it away from other metal objects
like paper clips, coins, keys, nails, screws, or other small metal objects that can
make a connection to one terminal to another. Shorting the battery terminals together
may cause burns or fire.
NOTICE: Under certain conditions, with the charger plugged into the power supply, the
charger can be shorted by foreign material. 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. Always unplug the charger
from the power supply when there is no battery pack in the cavity. Unplug the charger before
attempting to clean.
Charging a Battery (Fig. C)
1. Plug the charger into an appropriate outlet before inserting battery pack.

2. Insert the battery pack 12 into the charger, making sure the battery pack is fully seated in the
charger. The red (charging) light will blink continuously indicating that the charging process
has started.
3. The completion of charge will be indicated by the red light remaining ON continuously. The
battery pack is fully charged and may be used at this time or left in the charger. To remove
the battery pack from the charger, push the battery release button
NOTE: To ensure maximum performance and life of lithium-ion battery packs, charge the battery
pack fully before first use.
Charger Operation
Refer to the indicators below for the charge status of the battery pack.

Hot/Cold Pack Delay*
* DCB107, DCB112, DCB113, DCB115, DCB118: The red light will continue to blink, but a
yellow indicator light will be illuminated during this operation. Once the battery pack has
reached an appropriate temperature, the yellow light will turn off and the charger will resume
the charging procedure.
The compatible charger(s) will not charge a faulty battery pack. The charger will indicate faulty
battery pack by refusing to light or by displaying a problem pack or charger blink pattern.
NOTE: This could also mean a problem with a charger.
If the charger indicates a problem, take the charger and battery pack to be tested at 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 will charge at a slower rate than a warm battery pack. The battery pack will
charge at that slower rate throughout the entire charging cycle and will not return to maximum
charge rate even if the battery pack warms.
The DCB118 charger is 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 if the Electronic Protection System engages. If this occurs,
WALT rechargeable
place the lithium-ion battery pack on the charger until it is fully charged.

Wall Mounting
DCB107, DCB112, DCB113, DCB115, DCB118
These chargers are designed to be wall mountable or to sit upright on a table or work surface. If
wall mounting, locate the charger within reach of an electrical outlet, and away from a corner or
other obstructions which may impede air flow. Use the back of the charger as a template for the
location of the mounting screws on the wall. Mount the charger securely using drywall screws
(purchased separately) at least 1" (25.4 mm) long, with a screw head diameter of 0.28–0.35"
(7–9 mm), screwed into wood to an optimal depth leaving approximately 7/32" (5.5 mm) of
the screw exposed. Align the slots on the back of the charger with the exposed screws and fully
engage them in the slots.
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.
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 and 75 °F (18 ° – 24 °C). DO NOT charge the battery pack in an
air temperature 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;
13 on the battery pack.
b. Check to see if receptacle is connected to a light switch which turns power off when you
turn out the lights;
c. Move the charger and battery pack to a location where the surrounding air temperature is
approximately 65 °F – 75 °F (18 ° – 24 °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 effect on the battery pack.
5. 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
charger cavities. Always unplug the charger from the power supply when there is no battery
pack in the cavity. Unplug the charger before attempting to clean.
6. Do not freeze or immerse the charger in water or any other liquid.
Storage Recommendations
1. The best storage place is one that is cool and dry, away from direct sunlight and excess heat
or cold.
2. For long storage, it is recommended to store a fully charged battery pack in a cool dry place
out of the charger for optimal results.
NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will
need to be recharged before use.
