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 automat-
ically 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 opera-
tion. 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 (DCB101)
Some chargers have a Problem Powerline 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
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 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;
b. Check to see if receptacle is connected to a light switch which turns power off when you
turn out the lights;
c. Move 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 affect 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 charger before attempting to clean.
6. Do not freeze or immerse charger in water or any other liquid.
WARNING: Shock hazard. Don't allow any liquid to get inside charger. Electric shock may
result.
CAUTION: 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.

Cat # Ft.-Lbs.
DCF899, DCF899H 700
CAUTION: Ensure fastener and/or system will withstand the level of torque generated by the
tool. Excessive torque may cause breakage and possible personal injury.
1. Place the accessory on the fastener head. Keep the tool pointed straight at the fastener.
2. Press switch to start operation. Release switch to stop operation. Always check torque with a
torque wrench, as the fastening torque is affected by many factors including the following:
• Voltage: Low voltage, due to a nearly discharged battery, will reduce fastening torque.
• Accessory size: Failure to use the correct accessory size will cause a reduction in
fastening torque.
• Bolt size: Larger bolt diameters generally require higher fastening torque. Fastening torque
will also vary according to length, grade, and torque coefficient.
• Bolt: Ensure that all threads are free of rust and other debris to allow proper fastening
torque.
• Material: The type of material and surface finish of the material will affect fastening torque.
• Fastening time: Longer fasten ing time results in increased fastening torque. Using a
longer fastening time than recom mended could cause the fasteners to be overstressed,
stripped or damaged.
