• 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.
• 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.

Charge Indicators
This charger is designed to detect certain problems that can arise. Problems are indicated by
the red light flashing at a fast rate. If this occurs, re-insert the battery pack into the charger. If the
problem persists, try a different battery pack to determine if the charger is working properly. If
the new pack charges correctly, then the original pack is defective and should be returned to a
service center or other collection site for recycling. If the new battery pack elicits the same trouble
indication as the original, have the charger and the battery pack tested at an authorized service
center.
HOT/COLD DELAY
DCB101
This charger has a hot/cold delay feature: when the charger detects a battery that is hot, it
automatically starts a delay, suspending charging until the battery has cooled. After the battery
has cooled, the charger automatically switches to the pack charging mode. This feature ensures
maximum battery life. The red light flashes long, then short while in the hot/cold delay mode.
DCB107, DCB112
The DCB107 and DCB112 chargers have a hot/cold delay feature. When the charger detects
a battery that is hot, it automatically delays charging until the battery has cooled. When the
charger detects a battery that is cold, it automatically delays charging until the battery has
warmed.
The red light will continue to blink, but a yellow indicator light will be illuminated during this
operation. Once the battery has cooled, the yellow light will turn off and the charger will resume
the charging procedure.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the charge indicator showing Pack
Charged.
WEAK BATTERY PACKS: Weak batteries will continue to function but should not be expected
to perform as much work.
FAULTY BATTERY PACKS: This charger will not charge a faulty battery pack. The charger will
indicate faulty battery pack by refusing to light or by displaying problem pack or charger.
NOTE: This could also mean a problem with a charger.
PROBLEM POWER LINE
Some chargers have a Problem Power Line indicator. When the charger is used with some
portable power sources such as generators or sources that convert DC to AC, the charger may
temporarily suspend operation, flashing the red light with two fast blinks followed by a pause. This
indicates the power source is out of limits.
Wall Mounting
DCB107, DCB112
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. Mount the charger
securely using drywall screws at least 1" (25.4 mm) long, screwed into wood to an optimal depth
leaving approximately 7/32" (5.5 mm) of the screw exposed.
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 +105 °F (+40.5 °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. A cold battery pack will charge at about half the rate of 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.
4. 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 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.
5. 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.
6. 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.
7. Do not freeze or immerse the charger in water or any other liquid.
WARNING: Shock hazard. Don't 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.
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.
