• 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
smaller the gauge number, the heavier the cord.

• Do not place any object on top of 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 charger with damaged cord or plug.
• Do not operate 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 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.
Using Automatic Tune-Up™ Mode
The automatic Tune-Up™ Mode equalizes or balances the individual cells in the battery pack
allowing it to function at peak capacity. Battery packs should be tuned up weekly or after
10 charge/discharge cycles or whenever the pack no longer delivers the same amount of
work. To use the automatic Tune-Up™, place the battery pack in the charger and leave it for
at least 8 hours. The charger will cycle through the following modes.
1. The red light will blink continuously indicating that the 1-hour charge cycle has started.
2. When the 1-hour charge cycle is complete, the light will stay on continuously and will no
longer blink. This indicates that the pack is fully charged and can be used at this time.
3. If the pack is left in the charger after the initial 1-hour charge, the charger will begin the
Automatic Tune-Up™ mode. This mode continues up to 8 hours or until the individual cells
in the battery pack are equalized. The battery pack is ready for use and can be removed
at any time during the Automatic Tune-Up™ mode.
4. Once the Automatic Tune-Up™ mode is complete, the charger will begin a maintenance
charge; the red indicator will remain lit.
Chargers
Your tool uses a D WALT 18 volt charger. Be sure to read all safety instructions before using
E
your charger. Consult the chart at the end of this manual for compatibility of chargers and
battery packs.
Charging Procedure (Fig. 3)
DANGER: Electrocution hazard. 120 volts present at charging terminals. Do not probe with
conductive objects. Danger of electric shock or electrocution.
1. Plug the charger into an appropriate outlet before inserting battery pack.
2. Insert the battery pack into 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 pack is fully charged and may be used at this time or left in the charger.
Indicator Light Operation
Charge Indicators
Some chargers are designed to detect certain problems that can arise with battery packs.
Problems are indicated by the red light flashing at a fast rate. If this occurs, re-insert battery
pack into the charger. If the problem persists, try a different battery pack to determine if the
charger is OK. 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 tested at an authorized
service center.
HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the charger detects a battery that
is hot, it automatically starts a Hot Pack 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 Pack Delay mode.
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.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the red light glowing indefinitely. The
charger will keep the battery pack fresh and fully charged.
NOTE: A battery pack will slowly lose its charge when kept out of the charger. If the battery
pack has not been kept on maintenance charge, it may need to be recharged before use.
A battery pack may also slowly lose its charge if left in a charger that is not plugged into an
appropriate AC source.
WEAK BATTERY PACKS: Chargers can also detect a weak battery pack. Such batteries are
still usable but should not be expected to perform as much work. The charger will indicate to
replace battery pack.
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 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 current at 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. Under certain conditions, with the charger plugged into the power supply, the exposed
charging contacts inside 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 charger
cavities. Always unplug the charger from the power supply when there is no battery pack

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. Long storage will not harm the battery pack or charger. Under proper conditions, they can
be stored for 5 years or more.

Cutting Action – Orbital or Straight (Fig. 8)
This jig saw is equipped 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 cutting 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.
