DeWalt D21007 Instruction Manual

• 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.
•m 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 dan-
gerous 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.
4.a=... 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 anoth- er tool.
SERVICE
_1_ Tool service must be performed only by qualified repair personnel. Service or mainte-
nance 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.
,e= ADDITIONAL SPECIFIC SAFETY INSTRUCTIONS FOR
DRILLS
"_ • Hold tool by insulated gripping surfaces when performing an operation where the
_ cutting 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.
• Wear safety goggles or other eye protection. Hammering and drilfing 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
E
tool.

r_ *- P" walls, floors or areas where live electrical wires may be encountered. Hold the tool only by insulat-
ed grasping surfaces to prevent electric shock if you drill or drive into a live wire.

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.

• 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.
safety equipment, such as those dust masks that are specially designed to filter out microscop-
ic 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.

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.
