General Safety Rules - For All Battery
Operated Tools

A WARNtNG t.Read and understand all instructions. Failure

to foflow aft instructions listed below may result in electric
shock, tire and/or serious persona! injudz

SAVE THESE #NSTRUCT#OHS

WORK AREA

* Keep your work area clean and well lit. Cluttered benches and

dark areas invite accident&

* Do not operate power tools in explosive atmospheres, such

as in the presence of flammable liquids, gases, or dust. Power
tools create sparks which may ignite t,_edust or fumes.

* Keep bystanders, ch#dren, and visitors away while operating

a power tool Distractions can cause you to lose control.

ELECTRICAL SAFETY

* Do not abuse the cord. Never use the cord to carry the tool.

Keep cord away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged cords may cre-

ate a tire.

* A battery operated tool with integral batteries or a separate

battery pack must be recharged only with the specified charg-
er for the battery. A cha_ger that may be suitable for one type of
battery may create a risk of tire when used with anot,_er battery:

* Use battery operated tool only with the specifically designated

battery pack. Use of any ot,_er batteries may create a risk of tire.

PERSONAL SAFETY

* Stay alert, watch what you are doing and use common sense

when operating a power tooL Do not use tool while tired or
under the influence of drugs, alcohol, or medication. A

moment of ,,hattention while operating power tools may result in
serious personal injury:

* Dress properly. Do not wearloose clothing or jewelry. Contain

long hair. Keep your hair, clothing, and gloves away from
moving parts. Loose clot,%_g,jewe/_ or tong hair can be caught
in moving parts. Air vents often cover moving parts and should also
be avoided.

* Avoidaccidentaistarting. Besureswitchisinthelockedoroff

position before inserting battery pack. Carrying tools wit,_your

finger on t,#eswitch or inserting the battery pack into a too! with the
sw,_'chor7invites accidents.

* Remove adjusting keys or wrenches before turning the tool

on. A wrench or a key t,_at is left attached to a rotating part of the

tool may result in personal injury:

* Do not overreach. Keep proper footing and balance at all

times. Proper footing and balance enables better control of the tool
in unexpected situations.

* Use safety equipment. Always wear eye protection. Dust mask,

non-skid safety shoes, hard ha_; or hearing protection must be

used for appropriate conditions.

TOOL USE AND CARE

* Use clamps or other practical way to secure and support the

workpiece to a stable platform. Holding t,_e work by hand or
against your body is unstable and may lead to a loss of control

* Do not force tool. Use the correct tool for your application. The

correct tool wfl/ do the job better and safer at the rate for which it is

designed.

* Do not use tool if switch does not turn it on or off. A tool that

cannot be controlled with t,_e swqtch is dangerous and must be

repaired.

* Disconnect battery pack from tool or place the switch in the

locked or off position before making any adjustments, chang-

ing accessories, or storing the tooL Such preventative safety
measures reduce the risk of starting the tool accidentally

* Storeidle tools out of reach of chiMren and other untrained

persons. Tools are dangerous in the hands of untrained users,

* Whenbatterypaekisnotinuse, keepitawayfromothermetal

objects like: paper clips, coins, keys, nails, screws, or other
small metal objects that can make a connection from one ter-
minal to another Shorting t,_e battery terminals together may
cause sparks, bums, or a fire,

* Maintain tools with care. Keep cutting tools sharp and clean.

Properly maintained tools, with sharp cutting edges are less tikely
to bind and are easier to control

* Check for misalignment or binding of moving parts, breakage

of parts, and any other condition that may affect the tool's
operation. If damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained tools.

* Use only accessories that are recommended by the manufac-

turer for your model Accessories that may be suitable for one
tool may create a risk of injury when used on anot,_er tool

SERWCE

* Tool service must be performed only by qualified repair per-

sonnel. Service or maim'enance performed by unquafified person-
ne/ may result in a risk of Zojurj4

* When servicing a tool, use only identical replacement parts.

Follow instructions in the Maintenance section of this manu-
aL Use of unauthorized pails or failure to follow Maintenance

Instructions may create a risk of shock or inju_

Additional Specific Safety Rules

* Hold tool by insulated gripping surfaces when performing an

operation where the tool may contact hidden wiring. Contact
with a "live" wire will also make exposed metal parts of t,_e tool
"live" and shock the operator.

A WARNING: Some dust created by power sanding, sawing, grind-
ing, drN/ing, and other construction activities contains chemicals
known to cause cancer, birth defects or other reproductive harm.
Some examples of t,_ese chemicals are:

* lead from lead-based paints,
* crystalline silica from bricks and cement and other masonry

products, and

* arsenic and chromium from chemically-treated lumbe_

Your risk from these exposures varies, depending on how often you
do t,_b type of work, To reduce your exposure to these chemicals:
work in a weft ventilated area, and work with approved safety equip-

ment, such as those dust masks that are specially designed to filter

out microscopic particles,
* A void prolonged contact with dust from power sanding, saw-

ing, grinding, drilling, and other construction activities. Wear

protective clothing and wash exposed areas with soap and

water Allowing dust to get into your mouth, eyes, or lay on t,_eskin

may promote absorption of harmful chemicals,
_WARNING: L,tse of this toot can generate and/or disburse dust,

#mportant Safety #.s*ruc*ions
for Batterv Packs

Your toot uses either a 12, 14.4 or 18 Volt DE'WALT battery pack_
When ordering replacement battery packs, be sure to include catalog

number and voltage: Extended Run-Time battery packs deliver 25%
more run-time than standard battery packs.

NOTE: Your tool will accept either standard or Extended Run Time
battery packs. However, be sure to select proper voitage. Batteries
slowly lose their charge when they are not on the charger, the best
place to keep your battery is on the charger at all times.

The battery pack is not fully charged out of the carton. Before using
the battery pack and charger, read the safety instructions below. Then
follow charging procedures outlined.

READ ALL INSTRUCTIONS

* Do not incinerate the battery pack even if it is severely dam-

aged or is completely worn out. The battery pack can explode in
a fire.

* A small leakage of fiquid from the battery pack cells may

occur under extreme usage or temperature conditions. ThLs
does not indicate a failure. However, if the outer seal is broken and
this leakage gets on your skin:

a. Wash quickly with soap and water.
b. Neutralize wh,#a mild acid such as lemon juice or vinega_
c. If battery liquid gets into your eyes, flush t,_em wh,_clean water

for a mit_imum of 10 minutes and seek immediate medical
attention. (Medical note: The liqdd /s 25-35% solution of potas-
sium ,_ydroxide.)

* Do not carry extra battery packs in aprons, pockets, or tool

boxes along with other metal objects. Battery pack could be
short cimuited causing damage to the battery pack and possibly
causing severe burns or fire.

* Charge the battery packs only in DEWALT chargers.

DO NOT splash or immerse in water or other liquids.

Do not store or use the tool and battery pack in locations
where the temperature may reach or exceed 105°F (40 °C)
(such as outside sheds or metal buildings in summer).

A DANGER: Never attempt to open t,_e battery pack for any reason.
If battery pack case is cracked or damaged, do not insert into charg-
er. Electric shock or electrocution may result. Damaged battery packs

should be returned to service center for recycling.

NOTE: Battery storage and carrying caps are provided

for use whenever the battery is out of the tool or charger. '_J#&_

Remove cap before placing battery in charger or tool.

A WARNtNG: Do not store or carry battery so that

metal objects can contact exposed battery terminals.

For example, do not place battery in aprons, pockets,
tool boxes, product kit boxes, drawers, etc. with loose nails,

screws, keys, etc. without battery cap. Wit,_out cap in place, battery

could short circuit causing fire or bums or damage to battery

CAUTION: Battery pack must be securely attached to tool If bat-

tory pack is detached, personal injury may result.

The _BF_C TM Seal

The RBRCTM (RechargeabIe Battery BecycI[ng Corpor-
ationt SeaI on the nickel-cadmium battery (or battery packt /_
indicates that the costs to recycle the battery (or battery __,_ ), )
pack) at the end of its useful life have already been paid by '_'

DEWALT. In some areas, it is illegai to place spent nicke!-

cadmium batteries in the trash or municipal solid waste stream and the

RBRC program provides an environmentally conscious alternative.
RBRC in cooperation with DEWALT and other battery users, has

established programs inthe United States to facilitate the collection of
spent nickel-cadmium batteries. Help protect our environment and
conserve natural resources by returning the spent nickel-cadmium
battery to an authorized DEWALT service center or to your !ocaI retail-
er for recycling. You may also contact your Ioca! recycling center for
information on where to drop off the spent battery.

* The charger is designed to operate on standard household

electrical power (t20 Volts). Do not attempt to use it on any

other voltage. This does net apply to the vehicular charge_

Using Automatic TUEJe_Up TM MOde

The Automatic Tune-UpTM Mode equalizes or balances the individual

cells in the battery pack allowing it to function at peak capacity. Battery

packs shouid 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 TM, ptace the battery pack in the charger
and Ieave it for at Ieast 8 hours. The charger w[II cycle through the fol-
lowing modes.

1. The red I[ght will blink continuously indicating that the 1-hour
charge cycle has started.

2. When the 1-hour charge cycle is complete, the light w[lI stay on
continuously and will no longer bI[nk. 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 TM 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 TM Mode.

4. Once the Automatic Tune-Up TM Mode is complete the charger w[l!
transition to a maintenance charge; the indicator light shuts off
when the Automatic Tune-Up TM Mode is complete.

LEAVING THE BATTERY PACK _NTHE CHARGER
The charger and battery pack can be left connected with the red light

glowing indefinitely. The charger wilI keep the battery pack fresh and

fully charged.

NOTE: A battery pack will stowly lose its charge when kept out of the

charger. Ifthe battery pack has not been kept on maintenance charge,

it may need to be recharged before use. A battery pack may also slow-
ly Iose its charge if left in a charger that is not plugged into an appro-
priate 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 inser-
tion, the charger wilI beep rapidly 8 times to indicate a weak battery
condition. The charger wiII then go on to charge the battery to the

highest capacity possible.

i_portant 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 tem-

perature 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 normaI condition, and does not indicate a

problem.

3. If the battery pack does not charge properly:
a. Check current at receptacle by pIugging 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 Iights.

c. Move charger and battery pack to a location where the

surrounding air temperature is approximately 65°F - 75°F (18°-
24°0).

d. If charging problems per_isL, Lake Lhe Loci, baLLery puck and

charger to your local service center.

4. The battery pack should be recharged when itfails to produce suf-
ficient power on jobs which were easily done previously. DO NOT
CONTINUE to use under these conditions. Follow the charging

procedure. You may aIso 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 woot, 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.

A WARNING: Don't a!low any i/quid to get inside charger. Electric

shock may resu/L Tofacilitate t,_ecooiing of the battery pack after use,

HG.2 HG.2A

avoid p/acit_g _,#echarger or battery pack in a warm environment such
as in a metal shed, or an uninsulated trailer.

A CAUTION: Never attempt to open _,_ebattery pack for any reason.

If the plastic housing of the battery pack breaks or cracks, return to a

service center for recycling.

installing and Removing the Battery Pack

NOTE: Make sure your battery pack is fully charged.

To install the battery pack into the toot handle, align the base of the
tool with the notch inside the tool's handle (Fig. 2) and slide the bat-
tery pack firmly into the handle until you hear the lock snap into place

as shown in Figure 2A.

To remove the battery pack from the tool, press the release buttons

and firmly pull the battery pack oat of the toot handle. Insert it into the

charger as described in the charger section of this manual.

Variable Speed Switch

To turn the tool on, squeeze the trigger switch. 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 fu!ly 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 too! will operate. Use lower speeds for starting holes without a cen-
terpunch, drilling in metals or plastics, driving screws and drilling

ceramics, or in any application requiring high torque. Higher speeds
are better for dri!ling in wood, wood compositions and for using abra-
sive and polishing accessories. For maximum tool life, use variable
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 (FJgo 3)

A forward/reverse control button FIG. 3
determines the direction of the Depressfor Reverse DepressforForward
tool and also serves as a lock off
button. To select forward rotation,

release the trigger switch and
depress the forward/reverse con-
trol button on the right side of the
tool. To select reverse, depress the forward/reverse control button on
the ieft side of the tool. The center position of the control button locks
the toot 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 rota-
tion, you may hear a click on start up. This is normal and does not indi-
cate a problem.

Terque Adjustment Cellar FIG.4

(Fig, 4)

The torque adjustment collar (A) is clearly
marked with numbers and a driI! bit

symbol.The collar should be rotated until the
desired setting is located at the top of the tool

(Fig. 4). Locators are provided in the collar to
eliminate the guess work when selecting fas-
tening torque. The higher the number on the
collar, the higher the torque and the larger the A
fastener which can be driven. To lock the

clutch for drilling operations, move to the drill
bit position.

Dual Range Gearing (Fig. 5)

The dual range feature of your Driver/Drift allows you
to shift gears for greater versatility.

To select the low speed, high torque setting, turn the
too! off and permit to stop. Slide the gear shifter for-
ward (towards the chuck) as shown in Figure 5. To

select the high speed, low torque setting, turn the tool

off and permit to stop. Slide the gear shifter 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 shifter is either completeJy

pushed forward or completely pushed back.

Keyless Single Sleeve Chuck

FIG.B_

z

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. Rotate the sleeve counterclock-
wise far enough to accept the desired accessory.

3. Insert the accessory about 3/4" (19 ram) into the chuck and tight-
en secureiy 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.

L¢ WARNING: Do not attempt to tighten drill bits (orany other acces-

sory) by gripping the front part of the chuck and turning the tool on.

Damage to the chuck and personal Lr,,jurymay resdL Always lock off
Lngger 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.

Operatien as a DHtl

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 dual

range gear shifter to match the speed and torque to the planned oper-

ation. Followthese 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 b!ock, etc., use carbide-tipped bits.

2. Be sure the materia! 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 the drill firmly with one hand on the grip and the other hand
on the bottom of the battery pack to control its twisting action.

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 upon 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.

Drilling in Weod

Holes in wood can be made with the same twist drills used for metal
These bits may overheat unless pulled out frequently to clear chips

from the flutes. For larger holes, use low speed wood bits. Work that

is likely to splinter should be backed up with a block of wood.

Drilling in Metals

Use a cutting lubricant when drilling metals_ The exceptions are cast
iron and brass which should be drilled dry. The cutting lubricants that

work best are sulphurized cutting oil or lard oil; bacon grease will also

serve the purpose.

Dritling Masonry

Use carbide tipped masonry bits at low speeds. Keep even force on

the dril! but not so much that you crack the brittle materials. A smooth,

even flow of dust indicates the proper drilling rate.

Operatien as a Screwdriver

Select the desired speed/torque range using the dual range gear
shifter on the top of tool to match the speed and torque to the planned
operation.
insert the desired fastener accessory into the chuck as you would any
drill bit. Make a few practice runs in scrap or unseen areas to deter-
mine the proper position of the clutch collar.
