ELECTRICAL SAFETY
WARNING: To avoid electrical hazards, fire hazards or damage to the
tool, use proper circuit protection.
This tool is wired at the factory for 110–120 V operation. It must be
connected to a 110–120 V 15 A time delayed fuse or circuit breaker. To
avoid shock or fire, replace power cord immediately if it is worn, cut or
damaged in any way.
ALWAYS WEAR A DUST MASK DESIGNED FOR USE WHEN
OPERATING A POWER TOOL IN A DUSTY ENVIRONMENT.
WARNING: Some dust created by power sanding, sawing, grinding,
drilling and other construction activities contains chemicals known to cause
cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks, cement and other masonry products
• Arsenic and chromium from chemically-treated lumber
Your level of 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 dust
masks that are specially designed to filter out microscopic particles.
!
GENERAL SAFETY WARNINGS

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 personal
injury.
WORK AREA
Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
Do not operate power tools in potentially
explosive environments, such as in the
presence of flammable liquids, gas or dust.
Power tools create sparks which may
ignite the dust or fumes.
Keep bystanders, children and visitors
away while operating the 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 plug
only one way.
If the plug does not fit fully into the outlet,
reverse the plug. If it still does not fit,
contact a qualified electrician to install a
polarized outlet. Do not alter the plug in
any way. Double insulation eliminates the
need for the three-prong grounded power
cord and grounded power supply system.
Avoid body contact with grounded surfaces
such as pipes, radiators, ranges and
refrigerators. There is increased risk of
electric shock if your body is grounded.
Do not expose power tools to rain or wet
conditions. Water entering the power tool
will increase the risk of electric shock.
Do not abuse the cord. Never use the cord
to carry the tool 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 outdoors, 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 the 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.
!
POWER TOOL SAFETY

PERSONAL SAFETY – cont’d
Avoid accidental starting. Be sure the
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 another 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 the tool. Use the correct tool
for your application. The correct tool will do
the job better and safer at the rate for
which it was designed.
Do not use the tool if the power 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
preventive 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
cutting 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 tool’s
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 personnel. Service or
maintenance performed by unqualified
personnel could result in 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.
POWER TOOL SAFETY

WARNING: Know your impact
drill. Read the Owner’s Manual
carefully. Learn the tool’s applications
and limitations, as well as the specific
potential hazards related to this tool.
Following this rule will reduce the risk of
electric shock, fire or serious injury.
WARNING: Never use the drill in
“impact” mode unless a proper
masonry bit is installed and you are
drilling in concrete.
WARNING: Always use safety
shield, hearing protection and dust
mask when operating the drill in
“impact” mode.
Wear eye protection. Use face or dust
mask along with safety goggles if operation
is dusty. Use hearing protection,
particularly during extended periods of
operation.
Do not wear gloves, neckties or loose
clothing.
Do not drill material too small to be
securely held.
Always keep hands out of the path of the
drill bit. Avoid awkward hand positions
where a sudden slip could cause your
hand to move into the path of the drill bit.
Secure workpiece. Use clamps or a vice to
hold the work when practical. It is safer
than using your hand and it frees both
hands to operate the tool.
Make sure there are no nails or foreign
objects in the part of the workpiece to be
drilled.
To avoid injury from accidental starting,
always remove the plug from the power
source before installing or removing a drill
bit, accessory or attachment.
Do not install or use any drill bit that
exceeds 7” (175 mm) in length or extends
more than 6” (150 mm) beyond the chuck
jaws. They can suddenly bend or break.
Before starting the operation, jog the drill
switch to make sure the drill bit does not
wobble or vibrate.
Do not use fly cutters or multiple-part hole
cutters, as they can come apart or become
unbalanced in use.
Make sure the spindle has come to a
complete stop before touching the chuck or
attempting to change the drill bit.
Always make sure the chuck is tight and
the drill bit firmly tightened in the chuck
before starting drill.

WARNING: Keep the extension
cord clear of the working area. Position
the cord so it will not get caught on the
workpiece, tools or any other obstructions
while you are working with the power tool.
Make sure any extension cord used with
this tool is in good condition. When using
an extension cord, be sure to use one of
heavy enough gauge to carry the current
the tool will draw. An undersized cord will
cause a drop in line voltage resulting in
loss of power and overheating.
The table at right shows the correct size to
use according to cord length and
nameplate ampere rating. If in doubt, use
the next heavier gauge. The smaller the
gauge number the heavier the cord.
Be sure your extension cord is properly
wired and in good condition. Always
replace a damaged extension cord or have
it repaired by a qualified electrician before
using it. Protect your extension cord from
sharp objects, excessive heat and damp or
wet areas.
Use a separate electrical circuit for your
power tools. This circuit must not be less
than 14 gauge wire and should be
protected with either a 15 A time delayed
fuse or circuit breaker. Before connecting
the power tool to the power source, make
sure the switch is in the OFF position and
the power source is the same as indicated
on the nameplate. Running at lower
voltage will damage the motor.

DRILLING
When drilling in smooth hard surfaces such
as metal, use a center punch to mark the
desired hole location. This will prevent the
drill bit from slipping off center as the hole
is started.
NOTES:
a) Use slower drilling speeds when drilling
larger holes.
b) Use masonry bit with drill in impact
mode ONLY when drilling in concrete.
The workpiece to be drilled should be
secured in a vise or with clamps to keep it
from turning as the drill bit rotates (Fig. 9).
1. Check drill bit to make sure it is firmly
locked into the drill chuck and the
forward / reverse switch is in the
forward position.
2. Hold the drill firmly with both hands
whenever possible. Use one hand to
grasp the handle and switch and the
other to grasp the body of the drill.
NOTE: Make sure the hand placed on
the body of the drill does not cover the
air vents. Covering these air vents will
reduce the motor cooling and possibly
lead to overheating the motor.
3. While holding the drill firmly, place the
point of the drill bit at the point to be
drilled. Depress the switch trigger to
start the drill.
4. Move the drill bit into the workpiece
applying only enough pressure to
keep the bit cutting. Do not force the
drill bit or apply sideways pressure to
elongate the hole.
ASSEMBLY AND OPERATION
Fig. 9

18
DRILLING – cont’d
WARNING: Be prepared for
binding and bit breakthrough. When
these situations occur, the drill bit has
the tendency to grab the workpiece.
This action will kick the drill opposite to
the direction of drill bit rotation and
could cause loss of control when
breaking through material as you
complete drilling the hole. If you are not
prepared, this loss of control can result
in possible serious injury.
When drilling metals, use a light oil on the
drill bit to keep it from overheating. The oil
will prolong the life of the drill bit and
improve the drill cutting action. If the bit
jams in the workpiece or if the drill stalls,
release the trigger switch immediately.
Remove the bit from the workpiece and
determine the reason for jamming.
DRILLING IN CONCRETE
WARNING: Always use a face
shield when drilling in concrete.
Always use the impact mode and slower
drill speeds for faster drilling in concrete.
Always use carbide tipped masonry bits.
CHUCK REMOVAL
The drill chuck must be removed in order
to use some accessories. To remove the
chuck:
1. Unplug the drill from the power
source.
