pull the plug from an outlet. Keep cord away from heat, oil,
sharp edges or moving parts. Replace damaged 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. When using an
extension cord, be sure to use one heavy enough to carry the
current your product will draw. An undersized cord will cause a drop
in line voltage resulting in loss of power and overheating. The
following table shows the correct size to use depending on cord
length and nameplate ampere rating. If in doubt, use the next
heavier gage. The smaller the gage number, the heavier the cord.

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 inattention while operating power tools may result in serious
personal injury,

• Dress properly. Do not wear loose clothing or jewelry. Contain

long hair. Keep your hair, clothing, and gloves away from
moving parts. Loose clothing, jewelry, or long hair can be caught

in moving parts.

• 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.

General Safety Rules for All Tools

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 accidents.

• 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

• Grounded tools must be plugged into an outlet properly

installed and grounded in accordance with all codes and
ordinances. Never remove the grounding prong or modify the
plug in any way. Do not use any adapter plugs. Check with a
qualified electrician if you are in doubt as to whether the outlet
is properly grounded. If the tools should electrically malfunction or

break down, grounding provides a low resistance path to carry
electricity away from the user.

• 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

384957/Drill 5/2/02 1:05 PM Page 4

• Remove adjusting keys or switches before turning the tool on.

A wrench or key that 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 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.

• Disconnect the plug from the power source before making any

adjustments, changing accessories, or storing the tool. Such
preventative safety measures reduce the risk of starting the tool
accidentally.

• Store idle tools out of reach of children and other untrained

persons. T ools are dangerous in the hands of untrained users.

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

Properly maintained tools, with sharp cutting edges are less likely 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 tools
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

manufacturer for your model. Accessories that may be suitable
for one tool, may become hazardous when used on another tool.

SERVICE

• Tool service must be performed only by qualified repair
personnel. Service or maintenance performed by unqualified

personnel could result in a risk of injury.

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

Follow instructions in the Maintenance section of this manual.

Use of unauthorized parts or failure to follow Maintenance
Instructions may create a risk of electric shock or injury.

Motor Brushes

TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.
Be sure your power supply agrees with nameplate marking. 120 V

AC/DC means the tool may be operated with alternating or direct
current within at a voltage of 120 V.

220/240V AC/DC means the tool may be operated with alternating or
direct current within a voltage range of 220 to 240 volts.

Voltage decrease of more than 10% will cause loss of power and
overheating. All tools are factory tested; if this tool does not operate,
check the power supply.

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. If
drilling thin material, 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 biting, but do not push hard enough to stall
the motor or deflect the bit.

384957/Drill 5/2/02 1:05 PM Page 1

Motor

Be sure that your power supply agrees with the voltage marked on
the nameplate of your power unit. 120 volts AC/DC means that the
tool may be operated with alternating current or direct current with a
voltage of 120 volts. 220/240 volts AC/DC means that the tool may
be operated with alternating or direct current within a voltage range
of 220 to 240 volts. A voltage decrease of more that 10% will cause
a loss of power, overheating, and potential tool damage. The tool
have been factory tested: if the tool does not operate check your
power supply.

Motor Brushes

Carbon brushes should be regularly inspected for wear.
Keep brushes clean and sliding freely in their guides. Carbon

brushes have varying symbols stamped into them, and if the brush
is worn down to the line closest to the spring, they must be replaced.
New brush assemblies are available at authorized service centers;
see TOOLS, ELECTRIC in the yellow pages.

If your drill does not have exterior inspection caps, brush inspection
should only be attempted by authorized service personnel. The
inspection should be made every two to six months, depending upon
usage.

Maintenance

Use only mild soap and damp cloth to clean the tool. Never let any
liquid get inside the tool; never immerse any part of the tool into a
liquid.

Bearings

DeWalt tools use both “closed” and “open” bearings.

CLOSED TYPE BEARINGS

The closed bearing is permanently lubricated at the factory to last the
life of the tool. Lubricant is retained in the bearing by two shields
(no-contacting metal plates), two seals (contacting felt or synthetic
rubber), or a combination of one shield and one seal.

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

6. 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 OFF AND ON IN AN ATTEMPT TO START A STALLED
DRILL — THIS CAN DAMAGE THE DRILL.

7. To minimize stalling or breaking through the material, reduce
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 prevent jamming.

Changing Speeds

These units are designed to operate with two speeds. The changing
of speeds is accomplished by using the Speed Shift Lever built into
the Gear Case of the unit. To obtain the desired speed, low or high,
follow the steps listed below:

LOW R.P.M.

1. Loosen the shift lever locking knob (1/4 turn counterclockwise).

2. Move shift lever toward motor until clutch teeth are fully engaged.

3. Retighten locking knob.

HIGH R.P.M.

1. Follow the above procedure with the exception that the Shift Lever
should be moved toward the spindle.

NOTE: Use wrench or pliers to tighten locking nut if it vibrates loose.
In normal operation, hand tightening will be sufficient.

*Shifting may accomplished more easily when the drill is running.
When not running, it may be necessary to turn the spindle by hand
to allow the clutch teeth to engage.

NOTE: Assemble locking knob, cup washer and flat washer to the
unit in the following sequence.

1. Flat washer

2. Cup washer (“Cup” of the washer toward the unit)

3. Locking knob - Place through washers and screw into shift lever.

OPEN TYPE BEARINGS

The open type bearings are open on one or both sides. Grease is
applied to these bearings at the factory, and further lubrication is
received from the grease in the gear case (if bearings are located in
this area). Roller, needle, and sleeve bearings all fall into the open
type classification.

Lubrication

DEWalt tools are properly lubricated at the factory and are ready for
use. Tools should be relubricated regularly every sixty to 120 days
depending on usage. Tools used constantly on production or heavy
duty jobs and tools exposed to heat may require more frequent lubri­cation.This should only be attempted by trained power tool repair
professionals such as those at your local authorized D

EWalt Service

Center.
Some DeWalt power tools are equipped with an oil hole located in the

rear of the tool. Periodically, place a few drops of SAE #10W or 20W
motor oil in this hole.

Accessories

Recommended accessories for use with your tool are available at
extra cost from your distributor or local service center.

ACCESSORY MUST BE RATED FOR USE AT SPEED EQUAL TO
OR HIGHER THAN NAMEPLATE R.P.M. OF TOOL WITH WHICH IT
IS BEING USED.
