• 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 two chargers together.
• The charger is designed to operate on standard 120 volt 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.

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 are present at charging terminals. Do not probe with
conductive objects. Electric shock or electrocution may result.
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 in 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 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. 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 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.
WARNING: Burn hazard. 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.

Torque Adjustment Collar (Fig. 1)
Your tool has an adjustable torque screwdriver mechanism for driving and removing a wide array
of fastener shapes and sizes and in some models, a hammer mechanism for drilling into masonry.
Circling the collar (C) are numbers, a drill bit symbol, and in some models, a hammer symbol. These
numbers are used to set the clutch to deliver a torque range. The higher the number on the collar,
the higher the torque and the larger the fastener which can be driven. To select any of the numbers,
rotate until the desired number aligns with the arrow.
Dual Range Gearing (Fig. 1)
The dual range feature of your driver/drill allows you to shift gears for greater versatility.
To select the low speed, high torque setting, turn the tool off and permit to stop. Slide the gear
selector (D) forward (towards the chuck) as shown in Figure 1.
To select the high speed, low torque setting, turn the tool off and permit to stop. Slide the gear
selector back (away from chuck).
NOTE: Do not change gears when the tool is running. If you are having trouble changing gears,
make sure that the dual range gear selector is either completely pushed forward or completely
pushed back.
Worklight (Fig. 1)
There is a worklight (E) located just above the trigger switch (A). The worklight will be activated when
the trigger switch is squeezed.
NOTE: The worklight is for lighting the immediate work surface and is not intended to be used as
a flashlight.
Keyless Single Sleeve Chuck (Fig. 1)
Your tool features a keyless chuck (F) with one rotating sleeve for one-handed operation of the
chuck. To insert a drill bit or other accessory, follow these steps.
1. Lock the trigger in the OFF position as previously described.
2. Grasp the black sleeve of the chuck with one hand and use the other hand to secure the
tool. Rotate the sleeve counterclockwise far enough to accept the desired accessory.
3. Insert the accessory about 3/4" (19 mm) into the chuck and tighten securely by rotating
the chuck sleeve clockwise with one hand while holding the tool with the other. Your tool is
equipped with an automatic spindle lock mechanism. This allows you to open and close the
chuck with one hand.
To release the accessory, repeat step 2 above.
WARNING: Do not attempt to tighten drill bits (or any other accessory) by gripping the front part
of the chuck and turning the tool on. Damage to the chuck and personal injury may result. Always
lock off trigger switch when changing acces sories.
Be sure to tighten chuck with one hand on the chuck sleeve and one hand holding the tool for
maximum tightness.
Drill Operation (Fig. 4)
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool from
power source before making any adjustments or removing/installing attachments or accessories.
WARNING: To reduce the risk of personal injury, ALWAYS ensure workpiece is anchored
or clamped firmly. If drilling thin material, use a wood "back-up" block to prevent damage to the
material.
1. Use sharp drill bits only. For WOOD, use the low speed setting and twist drill bits, spade bits,
power auger bits, or hole saws. For METAL, use the low speed setting and steel twist drill bits
or hole saws. For MASONRY, such as brick, cement, cinder block, etc., use carbide-tipped bits
rated for percussion drilling. Use low speed for bits greater than 3/8" (10 mm).
2. Always apply pressure in a straight line with the bit. Use enough pressure to keep drill biting,
but do not push hard enough to stall the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting action of the drill. If model is not equipped
with side handle, grip drill with one hand on the handle and one hand on the battery pack.
CAUTION: Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip the
drill firmly to control the twisting action and avoid injury.
4. IF DRILL STALLS, it is usually because it is being overloaded or improperly used. RELEASE
TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO
NOT CLICK TRIGGER ON AND OFF IN AN ATTEMPT TO START A STALLED DRILL —
THIS CAN DAMAGE THE DRILL.
5. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit
through the last fractional part of the hole.
6. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
7. With variable speed drills there is no need to center punch the point to be drilled. Use a slow
speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep
enough to drill without the bit skipping out.
Hammerdrill Operation (Fig. 5)
1. Turn the collar (C) to the hammerdrill symbol.
2. Select the high speed setting by sliding the selector back (away from the chuck).
IMPORTANT: Use carbide-tipped or masonry bits only.
3. Drill with just enough force on the hammer to keep it from bouncing excessively or "rising" off
the bit. Too much force will cause slower drilling speeds, overheating and lower drilling rate.
4. Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit
when drillling as this will cause clogging of the bit flutes and a slower drilling speed.
5. When drilling deep holes, if the hammer speed starts to drop off, pull the bit partially out of the
hole with tool stil running to help clear debris from the hole.
NOTE: A smooth, even flow of dust from the hole indicates proper drilling rate.

Screwdriver Operation (Fig. 6)
1. Select the desired speed/torque range using the dual range gear selector to match the speed
and torque of the planned operation.
2. Turn the torque adjustment collar to the desired position. Lower numbers indicate lower torque
settings; higher numbers indicate higher torque settings.
3. Insert the desired fastener accessory into the chuck as you would any drill bit.
4. Make some practice runs in scrap or on unseen areas to determine the proper position of the
clutch collar.
5. Always start with lower torque settings, then advance to higher torque settings to avoid
dfamage to the workpiece or fastener.
MAINTENANCE
WARNING: To reduce the risk of serious personal injury, turn tool off and remove the
battery pack before making any adjustments or removing/installing attachments or
accessories. An accidental start-up can cause injury..
Cleaning
WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week. To
minimize the risk of eye injury, always wear ANSI Z87.1 approved eye protection when performing
this.
