• 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 household electrical power (120
Volts). Do not attempt to use it on any other voltage. This does not apply to the vehicu-
lar 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. Whenever 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 Tune-Up™ Mode.
4. Once the Automatic Tune-Up™ Mode is complete the charger will transition to a mainte-
nance charge; the indicator light shuts off when the Automatic Tune-Up™ Mode is complete.
SAVE THESE INSTRUCTIONS FOR FUTURE USE
Chargers
Your tool uses a 7.2, 9.6, 12.0, 14.4, or 18.0 Volt D
in D
WALT 1 Hour Chargers, 15 Minute Chargers or Vehicular 12 Volt Charger. Be sure to read
E
all safety instructions before using your charger. Consult the chart at the end of this manual for
compatibility of chargers and battery packs.
Charging Procedure
DANGER: Electrocution hazard. 120 volts are present at charging terminals. Do not probe with
conductive objects.
1. Plug the charger into an appropriate outlet before inserting battery pack.
2. Insert the battery pack into the charger, as shown in Figure 3, making sure the pack is fully
seated. 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. Such batteries are still
usable but should not be expected to perform as much work. In such cases, about 10 seconds
after battery insertion, the charger will beep rapidly 8 times to indicate a weak battery condition.
The charger will then go on to charge the battery to the highest capacity possible.
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, 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. Do not allow any liquid to get inside charger.
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.

OPERATION
Installing and Removing the Battery Pack
NOTE: Make sure your battery pack is fully charged.
CAUTION: Lock trigger switch before removing or installing battery.
To install the battery pack into the tool handle, align the base of the tool with the notch inside
the tool's handle (Fig. 4) and slide the battery pack firmly into the handle until you hear the lock
snap into place (Fig. 5).
To remove the battery pack from the tool, press the release buttons (A) and firmly pull the bat-
tery pack out of the tool handle. Insert it into the charger as described in the charger manual.
Trigger Switch (Fig. 1)
To start the jig saw, squeeze the trigger switch (C).
To slow and stop the jig saw, release the trigger switch.
VARIABLE SPEED
As the trigger switch is pressed in, the strokes-per-minute continue to increase, but not to
exceed the maximum setting on the speed control dial. As the trigger is released, the blade
strokes-per-minute reduce.
The lock button (D) should be depressed whenever the tool is not in use to eliminate the chance
of accidental starting (Fig. 6)
Blade Installation and Removal
CAUTION: Turn off tool and remove battery before making any adjustments or remov-
ing/installing attachments or accessories.
