This instruction manual includes the following:

• General Safety Rules

• Specific Safety Rules and Symbols

• Functional Description

• Assembly

• Operation

• Maintenance

• Accessories

!

ALWAYS WEAR EYE PROTECTION THAT CONFORMS WITH CSA
REQUIREMENTS or ANSI SAFETY STANDARD Z87.1

FLYING DEBRIS can cause permanent eye damage. Prescription
eyeglasses ARE NOT a replacement for proper eye protection.

WARNING: Non-compliant eyewear can cause serious injury if

broken during operation of a power tool.

SAVE THESE INSTRUCTIONS FOR REFERENCE

periods of operation of the tool or if the operation is noisy.

!

GENERAL SAFETY WARNINGS

4

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.

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.
