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, DCB102, DCB103
These chargers have a hot/cold delay feature. When the charger detects a battery that is too hot or
too cold, it automatically starts a delay, suspending charging. The red light flashes long, then short
while in the hot/cold delay mode.
Once the battery has reached an optimum temperature, the charger will automatically resume the
charging procedure. This feature ensures maximum battery life.
DCB107, DCB112, DCB113, DCB115
These chargers have a hot/cold delay feature. When the charger detects a battery that is too hot
or too cold, it automatically starts a delay, suspending charging. The red light will continue to blink,
but a yellow indicator light will be illuminated during this suspension.
Once the battery has reached an optimum temperature, the yellow light will turn off and the charger
will automatically resume the charging procedure. This feature ensures maximum battery life.
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
DCB101, DCB102, DCB103
These chargers 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.
DCB107, DCB112, DCB113, DCB115
These chargers will not charge a faulty battery pack. The charger will indicate faulty battery pack by
refusing to light.
NOTE: This could also mean a problem with a charger.
Wall Mounting
DCB107, DCB112, DCB113, DCB115
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 +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. 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.

Cutting Action – Orbital or Straight (Fig. 8)
This jig saw is equipped with four cutting actions, three orbital and one straight. Orbital action has
a more aggressive blade motion and is designed for cutting in soft materials like wood or plastic.
Orbital action provides a faster cut, but with a less smooth cut across the material. In orbital action,
the blade moves forward during the cutting stroke in addition to the up and down motion.
NOTE: Metal or hardwoods should never be cut in orbital action.
To adjust the cutting action, move the orbital action lever (H) between the four cutting positions:
0, 1, 2, and 3. Position 0 is straight cutting. Positions 1, 2, and 3 are orbital cutting. The
aggressiveness of the cut increase as the lever is adjusted from one to three, with three being the
most aggressive cut.
Dust Blower (Fig. 9)
The dust blower helps clear the cutting area of debris created from the blade.
NOTE: When cutting metal, turn the dust blower off so cutting fluids are not blown away from the
blade.
To turn the dust blower on, slide the dust blower control (I) all the way to the top.
To turn the dust blower off, slide the dust blower control all the way to the bottom.
Removeable No-Mar Shoe Cover (Fig. 10)
The no-mar shoe cover (J) should be used when cutting surfaces that scratch easily, such as
laminate, veneer or paint.
To attach no-mar shoe cover, place the front of the aluminum shoe (G) into the front of the no-mar
shoe cover (J) and lower the jig saw. The no-mar shoe will click securely onto the rear of aluminum
shoe.
