General Safety Rules
WARNING! Read and understand all instructions. Failure to follow all
instructions listed below may result in electric shock, fire and/or serious per-
sonal 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. Applicable only to Class I (grounded) tools.
• 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. If 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. Applicable
only to Class II (double insulated) tools.
• 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 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. 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 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. Tools 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.
Additional Specific Safety Instructions
• Hold tool by insulated gripping surfaces when performing an operation where the cut-
ting tools may contact hidden wiring or its own cord. Contact with a “live” wire will make
exposed metal parts of the tool “live” and shock the operator.
• Accessories must be rated for at least the speed recommended on the tool warning
label. Wheels and other accessories running over rated speed can fly apart and cause
injury. Accessory ratings must be above listed minimum wheel speed as shown on tool
nameplate.
• Wear safety goggles or other eye protection. Hammering and drilling operations cause
chips to fly. Flying particles can cause permanent eye damage.
• Keep handles dry, clean, and free from oil and grease. This will enable better control of
the tool.
• Always use the side handle supplied with the tool. Keep a firm grip on the tool at all
times. Do not attempt to operate this tool without holding it with both hands. Operating this
tool with one hand will result in loss of control. Breaking through or encountering hard mate-
rials such as re-bar may be be hazardous as well.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con-
struction activities contains chemicals known to cause cancer, birth defects or other reproduc-
tive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber (CCA).
Your risk from these exposures varies, depending on how often you do this type of work. To
reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to filter out
microscopic particles.
• Avoid prolonged contact with dust from power sanding, sawing, 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 the skin may promote
absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust, which may cause serious and
permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protec-
tion appropriate for the dust exposure. Direct particles away from face and body.
CAUTION: Wear appropriate hearing protection during use. Under some conditions and
duration of use, noise from this product may contribute to hearing loss.
• The label on your tool may include the following symbols. The symbols and their definitions
are as follows:
V ..............volts A................amperes
Hz ............hertz W ..............watts
min............minutes ............alternating current
..........direct current
n
o..............no load speed
..............Class II Construction ..............earthing terminal

SAVE THESE INSTRUCTIONS
Motor
Your DEWALT tool is powered by a DEWALT-built motor. Be sure your power supply agrees with the
nameplate marking. Volts 50/60 Hz or “AC only” means your tool must be operated on alternating
current and never with direct current. Voltage decrease of more than 10% will cause loss of power
and overheating. D
EWALT tools are factory tested; if this tool does not operate, check power supply.
Torque
CAUTION: Always use the side handle and switch handle. This is a high-torque drill. Always
hold it firmly with both hands when operating.
Torque is the twisting action which the drill imparts to the bit. As the drill bit meets resistance in
the material being drilled, the motor responds by adjusting the output torque to meet the
requirement up to the maximum capacity of the motor and gear system.
At any value of drilling torque, there is a reaction force on the drill which the operator restrains.
On the DW124, the operator is grasping the switch handle near the point of cord entry and the
side handle which is screwed into the gear case. The gripping surfaces of these two handles are
at significant distances from the drill bit thereby giving the operator ample control over the tool.
In addition to the optimized handle design, the DW124 contains a slip clutch in the low speed
range which softens the mechanical shock imparted to the operator when the large diameter
cutters bite into the work.
Assembling Side Handle
Two threaded bosses as shown in Figure 2 are for installation of the side handle. Install side
handle as shown on desired side and tighten securely by hand. The side handle should always
be used and is especially important when drilling in the low speed setting.
Assembling Bail Handle
A bail handle is provided for carrying the tool and for use as a hand hold when drilling where
space limitations prevent the use of the side handle. Assemble the bail handle in either of the
positions shown in Figure 3. When changing the location of the bail handle from one position to
the other, it is necessary to remove completely the two bolts securing it. These bolts can be
loosened or tightened with a quarter or other suitable coin as shown in Figure 4. Turn the handle
around (1/2 turn) and reinstall as desired. Always operate this tool with the bail handle installed.
Shifting to the Desired Speed
To select high speed (1200 RPM) pull up on the speed selector and slide it to the position shown
in Figure 5. Make sure that when you release the selector, it snaps down into the detent in the
housing.
To select low speed (300 RPM) pull up on the speed selector and slide it to the position shown
in Figure 6. Make sure that when you release the selector, it snaps down into the detent in the
housing.
NOTE: It may be necessary to rotate the chuck slightly by hand when shifting speeds. Never
change speeds when the drill is running or coasting.
Switches
Depressing the trigger switch turns the tool “ON,” releasing the trigger switch turns the tool
“OFF.” There is a slide switch built into the handle directly behind the trigger switch for operating
in reverse. For drilling, this switch is put in the “F” position and for reversing operations, it is
pushed to the “R” position.
NOTE: The switch provided is a common part for use on several other tools. Ignore the “HI/LO”
markings for this drill. A built in mechanical interlock prevents operation of the slide switch
unless the trigger is released. Avoid reversing the drill’s direction while it is still coasting to a
stop.
Operation
CAUTION: Always unplug the tool when attaching or changing bits or accessories.
1. Open the chuck jaws by turning collar with fingers and insert bit fully into the chuck. Tighten
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 bit, turn chuck key
counter clockwise in just one hole, then loosen chuck by hand.
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.
5. Hold drill firmly to control the twisting action of the drill. Use side handle.
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.
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 STARTA STALLED
DRILL — THIS CAN DAMAGE THE DRILL.
7. To minimize stalling on 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.
9. A ratcheting sound heard while using the tool in low speed indicates that the clutch is
disengaging due to a high load. Continuous use of the tool with the clutch ratcheting is not
recommended.
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 sulphurized cutting oil or lard oil;
bacon grease will also serve the purpose.
Drilling in Wood
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 Power Drill
Wood Bits. Work that is apt to splinter should be backed up with a block of wood. When using
Self Feed bits, no pressure is required as these bits will pull themselves into the wood.
NOTE: If the clutch slips while using a self feed bit, rock the drill slightly by pushing the switch
handle toward the material being drilled and then pulling it back toward you several times.
Drilling in Masonry
Use carbide tipped masonry bits at low speeds. Keep even force on the drill but not so much
that you crack the brittle materials. A smooth, even flow of dust indicates the proper drilling rate.
Chuck Key Holder
1. Push double-hole end of holder through the slot in other end of holder (Fig. 7).
2. Slip loop over electric plug and draw loop tight around cord (Fig. 8).
3. Push ends of chuck key handle through two holes in end of holder (Fig. 9).
Cleaning
With the tool motor running, blow dirt and dust out of all air vents with dry air at least once a
week.
Lubrication
Your tool was properly lubricated before leaving the factory. In from two to six months,
depending upon use, take or send your tool to a D
EWALT Service Center or other qualified
service organization for a complete cleaning, inspection and relubrication.
Tools used constantly on production or heavy duty jobs or exposed to heat may require more
frequent lubrication. Tools “out of service” for long periods should be relubricated before being
put back into service.
Motor Brushes
This DEWALT tool uses an advanced brush system which automatically stops the drill when the
brushes wear out. This prevents serious damage to the motor.
Accessories
Recommended accessories for use with your tool are available at extra cost from your
distributor or local service center.
CAUTION: The use of any non-recommended accessory may be hazardous.
