Important Safety Instructions for Battery Chargers

SAVE THESE INSTRUCTIONS: This manual contains important safety instructions for battery chargers.

• Before using charger, read all instructions and cautionary markings on charger, battery pack, and product using bat-

tery pack.

DANGER: 240 Volts are present at charging terminals. Do not probe with conductive objects. Electric shock or electro-

cution may result.

WARNING: Do not allow any liquid to get inside charger. Electric shock may result.

CAUTION: To reduce the risk of injury, charge only D

EWALT nickel cadmium rechargeable batteries. Other types of batter-

ies may burst causing personal injury and damage.

CAUTION: Under certain conditions, with the charger plugged in to 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.

• DO NOT attempt to charge the battery pack with any chargers other than the ones in this manual. The charger

and battery pack are specifically designed to work together.

• These chargers are not intended for any uses other than charging D

EWALT rechargeable batteries. Any other

uses may result in risk of fire, electric shock or electrocution.

• Do not expose charger to rain or snow.

• Pull by plug rather than cord when disconnecting charger. This will reduce risk of damage to electric plug and

cord.

• Make sure that cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage

or stress.

• Do not use an extension cord unless it is absolutely necessary. Use of improper extension cord could result in risk

of fire, electric shock, or electrocution.

• 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.

When using more than one extension to make up the total length, be sure each individual extension contains at least

the minimum wire size.

• Do not place any object on top of charger or place the charger on a soft surface that might block the ventila-

tion 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 — have them replaced immediately.

• 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 household electrical power (240 Volts). 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 indi-

cates 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 bat-

tery 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 maintenance 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 12.0, 14.4, or 18.0 Volt DEWALT Charger. Your

battery can be charged in D

EWALT 1 Hour Chargers, 15 Minute

Chargers or Vehicular 12 Volt charger. Be sure to read all safety

instructions before using your charger. Consult the chart on the

back cover of this manual for compatibility of chargers and bat-

tery packs.

Charging Procedure (Fig. 1)

DANGER: 240 Volts are present at charging terminals. Do not probe with conductive objects. Electric shock or electro-

cution may result.

1. Plug the charger into an appropriate outlet.

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, reinsert 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 automati-

cally 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 bat-

tery 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.

FIG. 1

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 pre-

viously. 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: 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.

OPERATION

Installing and Removing the Battery Pack (Fig. 2)

NOTE: Make sure your battery pack is fully charged.

To install the battery pack into the tool handle, align the base of the tool with the notch

inside the tool’s handle and slide the battery pack firmly into the handle until you hear

the lock snap into place.

To remove the battery pack from the tool, press the release buttons and firmly pull the

battery pack out of the tool handle. Insert it into the charger as described in the charger

manual.

Variable Speed Switch (Fig. 3)

To turn the tool on, squeeze the trigger switch (A). To turn the tool off, release the trigger switch. Your tool is equipped

with a brake. The chuck will stop as soon as the trigger switch is fully released.

The variable speed switch enables you to select the best speed for a particular application. The farther you squeeze the

trigger, the faster the tool will operate. Use lower speeds for starting holes without a centerpunch, drilling in metals or

plastics, driving screws and drilling ceramics, or in any application requiring high torque. Higher speeds are better for

drilling in wood, wood compositions and for using abrasive and polishing accessories. For maximum tool life, use vari-

able speed only for starting holes or fasteners.

NOTE: Continuous use in variable speed range is not recommended. It may damage the switch and should be avoided.

Forward/Reverse Control Button (Fig. 3)

A forward/reverse control button (B) determines the direction the tool will spin and also serves as a lock off button.

To select forward rotation, release the trigger switch and depress the forward/reverse control button on the right side of

the tool.

To select reverse, depress the forward/reverse control button on the left side of the tool.

The center position of the control button locks the tool in the off position. When changing the position of the control

button, be sure the trigger is released.

NOTE: The first time the tool is run after changing the direction of rotation, you may hear a click on start up. This is

normal and does not indicate a problem.

Torque Adjustment Collar (Fig. 4)

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, and 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.

Three Speed Gearing (Fig. 4)

The three speed feature of your tool allows you to shift gears for greater versatility. To select speed 1 (highest torque

setting), turn the tool off and permit it to stop. Slide the gear shifter (D) all the way to the left. Speed 2 (middle torque

and speed setting) is in the middle position. Speed 3 (highest speed setting) is to the right.

NOTE: Do not change gears when the tool is running. Always allow the drill to come to a complete stop before changing

gears. If you have trouble changing gears, make sure that the gear shifter is engaged in one of the three speed settings.

Keyless Single Sleeve Chuck (Fig. 5)

Your tool features a keyless chuck 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 as shown in Figure 4. Rotate the sleeve counterclockwise far

enough to accept the desired accessory.

3. Insert the accessory about 19mm (3/4") 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

accessories.

Be sure to tighten chuck with one hand on the chuck sleeve and one hand holding the tool for maximum tightness.

Side Handle (Fig. 6)

CAUTION: Always hold drill with both hands and use side handle if so equipped. Side handle

clamps to the front of the gear case as shown and can be rotated 360˚ to permit right- or

left-hand use. Be sure side handle is installed tightly. If model is not equipped with side handle,

grip drill with one hand on the handle and one hand on the battery pack.

NOTE: Side handle comes equipped on models DC987, DC988, DC989.

Operation as a Drill

Turn the collar to the drill bit symbol. Install and tighten the desired drill bit in the chuck. Select

the desired speed/torque range using the gear shifter to match the speed and torque to the

planned operation. Follow these instructions for best results when drilling.

DRILLING

1. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits, power auger bits, or hole saws. For METAL, use

high speed steel twist drill bits or hole saws. For MASONRY, such as brick, cement, cinder block, etc., use carbide-

tipped bits.

2. Be sure the material to be drilled is anchored or clamped firmly. If drilling thin material, use a “back-up” block to

prevent damage to the material.

3. Always apply pressure in a straight line with the bit. Use enough pressure to keep the drill bit biting, but do not

push hard enough to stall the motor or deflect the bit.

4. Hold tool firmly to control the twisting action of the drill.

5. IF DRILL STALLS, it is usually because it is being overloaded. RELEASE TRIGGER IMMEDIATELY, remove drill bit

from work, and determine cause of stalling. DO NOT CLICK TRIGGER OFF AND ON IN AN ATTEMPT TO START A

STALLED DRILL – THIS CAN DAMAGE THE DRILL.

6. To minimize stalling as you are breaking through the material, reduce pressure on drill and ease the bit through the

last fractional part of the hole.

7. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming.

8. 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.

Operate at full on after starting the bit.
