•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.

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,
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.
