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.

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.

Motor

Your D

WALT tool is powered by a D

E

WALT-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

E

WALT 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.
