• Do not overreach. Keep proper footing and balance at all times. Proper footing and bal-
ance enables better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes,
hard hat, 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 the work by hand or against your body is unstable and may lead to loss
of control.
Do not force tool. Use the correct tool for your application. The correct tool will 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. Any tool that cannot be controlled
_, with the switch is dangerous and must be repaired.

GENERAL SAFETY INSTRUCTIONS FOR ALL TOOLS
z_ WARNING! Read and understand all instructions. Failure to follow all instructions listed
below may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
• Keep your work area clean and well lit Cluttered benches and dark areas invite acci-
dents.
• 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 the dust
or fumes.
• Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL SAFETY
• Double insulated tools are equipped with a polarized plug (one blade is wider than
the other.) This plug will fit in a polarized outlet only one way. ff the plug does not fit
fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician
to install a polarized outlet. Do not change the plug in any way. Double insulation []
eliminates the need for the three wire grounded power cord and grounded power supply
system.
• Avoid body contact with grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is grounded.
• Don't expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
• Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an
outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace dam-
aged cords immediately. Damaged cords increase the risk of electric shock.
• When operating a power tool outside, use an outdoor extension cord marked "W-A"
or "W." These cords are rated for outdoor use and reduce the risk of electric shock.

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 medica-
tion. A moment of inattention while operating power tools may result in serious personal
injury,
• Dress properly. Do not wear loose clothing orjewelry. Contain long hair. Keep your
hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair
can be caught in moving parts. Air vents often cover moving parts and should also be avoided.
• Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with
your finger on the switch or plugging in tools that have the switch on invites accidents.
• Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that
is left attached to a rotating part of the tool may result in personal injury.

Motor Brushes
DEWALT uses an advanced brush system which automatically stops the drill when the brush-
es wear out. This prevents serious damage to the motor.
Switches (Figure 1)
To start the drill, depress the trigger switch; to stop the drill, release the trigger.
A variable speed trigger switch (A) permits speed control--the farther the trigger is depressed,
the higher the speed of the drill.
NOTE: Use lower speeds for starting holes without a center punch, drilling in metal or plas-
tics, driving screws or drilling ceramics. Higher speeds are better for drilling wood and com-
position boards and using abrasive and polishing accessories.
The reversing lever (B) is used for withdrawing bits from tight holes and removing screws. It
is located above the trigger switch. To reverse the motor, release the trigger switch FIRST and
then push the lever to the right. After any reversing operations, return lever to forward posi-
tion.
OPERATION
Drilling
1. Always unplug the drill when attaching or changing bits or accessories.
2. 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.
3. Be sure the material to be drilled is anchored or clamped firmly. When drilling thin materi-
al, use a wood "back-up" block to prevent damage to the material.
4. Always apply pressure in a straight line with the bit. Use enough pressure to keep drill bit-
ing, but do not push hard enough to stall the motor or deflect the bit.
5. Hold tool firmly to control the twisting action of the drill.
6. Overloading and improper use may cause the drill to stall. If the drill stalls, release the trig-
ger immediately remove drill bit from work, and determine cause of stalling. Do not click
the trigger off and on in an attempt to start the drill -- this can damage the drill.
7. To minimize stalling or breaking through the material, reduce the pressure on drill and ease
the bit through the last fractional part of the hole.
8. Keep the motor running when pulling the bit back out of a drilled hole. This will help pre-
vent jamming.
9. Because of the variable speed switch, 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.
DRILLING IN METAL
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 sulfurized cutting oil or lard oil;
bacon-grease will also serve the purpose.

Bubble Level (Figure 2)
Your drill is equipped with a bubble level (C) that assists you in drilling level holes.
For horizontal drilling, tilt the drill up or down as required so that the bubble floats in the cen-
ter of the parallel lines drawn on the glass. When the bubble is centered between the lines,
the drill is level.
For vertical drilling, align the drill so that the bubble floats in the center of the bull's-eye, (D).
To assure accuracy, first place a level on your work piece and position it so that it is level.
Then, when the drill reads level, the two will be aligned. (Any bubble level can only indicate
level to the earth's surface).
NOTE: The level is filled with mineral oil that may cause minor skin irritation when contacted.
If the level breaks and this fluid gets on your skin, rinse thoroughly with water. If any liquid gets
in your eyes, rinse thoroughly with water and call a physician immediately.
Keyless Chuck (D21008, D21009)
Your tool features a keyless chuck for greater convenience. To insert a drill bit or other acces-
sory, follow the steps listed below.
1. Unplug the drill.
2. Grasp the rear half of the chuck with one hand and use your other hand to rotate the front
half counterclockwise, as shown in Figure 4. Rotate far enough so that the chuck opens
sufficiently to accept the desired accessory.
3. Insert the bit or other accessory about 3/4" into the chuck and tighten securely by holding
the rear half of the chuck and rotating the front portion in the clockwise direction. When the
chuck is nearly tightened, you will hear a clicking sound. After 4-6 clicks, the chuck is
securely tightened around the accessory.
4. To release the accessory, repeat step 2 listed above.
Z_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.
Keyless Chuck Removal (D21008, D21009)
Turn off and unplug the drill before making any adjustments. Tighten the chuck around
the shorter end of a hex key (not supplied) of 1/4" or greater size. Using a soft hammer or
piece of wood, strike the longer end in the counterclockwise direction, as shown in Figure 4.
This will loosen the chuck so that it can be unscrewed by hand.
Chuck Installation
Screw the chuck on by hand as far as it will go. Tighten the chuck around the shorter end of
a 1/4" or larger hex key (not supplied) strike the longer end in the clockwise direction with a
soft hammer, as shown in Figure 5.
Using the Keyed Chuck (D21002)
Open the chuck jaws by turning collar with by hand and insert the shank of the bit about 3/4" into
chuck. Tighten the chuck collar by hand. Place chuck key in each of the three holes, and tighten
in clockwise direction. It's important to tighten chuck with all three holes. To release the bit, turn the
chuck counterclockwise in just one hole, then loosen the chuck by hand.
Removal of Keyed Chuck
Turn off and unplug the drill before making any adjustments. Tighten the chuck around
the shorter end of a hex key (not supplied) of 1/4" or greater size. Strike the key sharply in the
counterclockwise direction when viewed from the front of the tool as shown in figure 7. This
will loosen the chuck so that it can be removed by hand.
Keyed Chuck Installation
Screw the chuck on by hand as far as it will go. Insert the shorter end of a hex key (not sup-
plied) of 1/4" or greater size and strike it in the clockwise direction with a soft hammer, as
shown in Figure 8.

REGLES DE sr:CURITr: Gr:Nr:RALES
ZLAVERTISSEMENT! Vous devez lire et comprendre toutes les instructions. Le non-
respect, mGme partiel, des instructions ci-apres entraTne un risque de choc electrique, d'in-
cendie et/ou de blessures graves.
AIRE DE TRAVAIL
• Veillez ace que I'aire de travail soit propre et bien _clair_e. Le desordre et le manque de
lumiere favorisent les accidents.
• N'utilisez pas d'outils _lectriques dans une atmosphere explosive, par exemple en
presence de liquides, de gaz ou de poussi_res inflammables. Les outils electriques
creent des etincelles qui pourraient enflammer les poussieres ou les vapeurs.
• Tenez a distance les curieux, les enfants et les visiteurs pendant que vous travaillez
avec un outil _lectrique. IIs pourraient vous distraire et vous faire faire une fausse
manoeuvre.
SI_CURITI_ I_LECTRIQUE
• Les outils a double isolation sont _quip_s d'une fiche polaris_e (une des lames est
plus large que I'autre), qui ne peut se brancher que d'une seule fa¢on dans une prise
polaris_e Ne modiflez pas la fiche de I'outil. La double isolation [] elimine le besoin d'un
cordon d'alimentation a trois ills avec mise a la terre ainsi que d'une prise de courant mise
la terre.
• Evitez tout contact corporel avec des surfaces mises a la terre (tuyauterie, radiateurs,
cuisini_res, r_frig_rateurs, etc.). Le risque de choc electrique est plus grand si votre corps
est en contact avec la terre.
• N'exposez pas les outils _lectriques a la pluie ou a I'eau. La presence d'eau dans un outil
electrique augmente le risque de choc electrique.
• Ne maltraitez pas le cordon. Ne transportez pas I'outil par son cordon etne d_branchez
pas la fiche en tirant sur le cordon. N'exposez pas le cordon a la chaleur, a des huiles,
des ar_tes vives ou a des pi_ces en mouvement. Remplacez imm_diatement un
cordon endommag& Un cordon endommage augmente le risque de choc electrique.
• Lorsqu'on utilise un outil _lectrique a I'ext_rieur, on ne dolt utiliser que des rallonges
con¢ues pour cet usage, comme celles de type W-A ou W, afin de reduire les risques de
choc electrique.
S¢:CURITE DES PERSONNES
• Restez alerte, concentrez-vous sur votre travail et faites preuve de jugement.
N'utilisez pas un outil _lectrique si vous _tes fatigu_ ou sous I'influence de drogues,
d'alcool ou de m_dicaments. Un instant d'inattention suffit pour entra;ner des blessures
graves.
