This tool has many features for making its use more pleasant and enjoyable. Safety, performance, and dependability
have been given top priority in the design of this product making it easy to maintain and operate.
A WARNING: Read and understand all instruc-
tions. 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 accidents.
[] Do not operate power tools in explosive atmo-
spheres, 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 polar-
ized 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.
[] 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.
PERSONAL SAFETY
[] Stay alert, watch what you are doing and use com-
mon 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 clothes,
jewelry, or long hair can be caught in moving parts.
[] 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.
[] 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, nonskid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
[] Do not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
[] Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected situations.
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 ap-
plication. 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 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 the 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 cut-
ting 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.
[] Keep the tool and its handle dry, clean and free
from oil and grease. Always use a clean cloth when
cleaning. Never use brake fluids, gasoline, petroleum-
based products, or any strong solvents to clean your
tool. Following this rule will reduce the risk of loss of
control and deterioration of the enclosure plastic.
SERVICE []
[] Tool service must be performed only by qualified
repair personnel. Service or maintenance performed
by unqualified personnel may result in a risk of injury.
When servicing a tool, use only identical replace-
merit 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 shock or injury.
[] Wear ear protectors with impact wrenches. Expo-
sure to noise can cause hearing loss.
[] Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with
a "live" wire will make exposed metal parts of the cut-
ting tool "live" and shock the operator.
[] Know your power tool. Read operator's manual
carefully. Learn its 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.
[] Always wear safety glasses. Everyday eyeglasses
have only impact-resistant lenses; they are NOT
safety glasses. Following this rule will reduce the risk
of serious personal injury.
[] Protect your lungs. Wear a face or dust mask if the
operation is dusty. Following this rule will reduce the
risk of serious personal injury.
[] Protect your hearing. Wear hearing protection dur-
ing extended periods of operation. Following this rule
will reduce the risk of serious personal injury.
[] Inspect tool cords periodically and, if damaged,
have repaired at your nearest Sears or other quali-
fied service center. Constantly stay aware of cord
location.
Following this rule will reduce the risk of electric shock
or fire.
[] Check damaged parts. Before further use of the
tool, a guard or other part that is damaged should
be carefully checked to determine that it will
operate properly and perform its intended func-
tion. Check for alignment of moving parts, binding
of moving parts, breakage of parts, mounting, and
any other conditions that may affect its operation.
A guard or other part that is damaged should be
properly repaired or replaced by an authorized ser-
vice center. Following this rule will reduce the risk of
shock, fire, or serious injury.
[] Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one
heavy enough to carry the current your product will
draw. A wire gauge size (A.W.G.) of at least 14 is
recommended for an extension cord 50 feet or less
in length. A cord exceeding 50 feet is not recom-
mended. If in doubt, use the next heavier gauge.
The smaller the gauge number, the heavier the
cord. An undersized cord will cause a drop in line volt-
age resulting in loss of power and overheating.
[] inspect for and remove all nails from lumber before
using this tool. Following this rule will reduce the risk
of serious personal injury.
[] Ifthepowersupplycord isdamaged, itmust be replaced
only by the manufacturer or by an authorized service
center to avoid risk.

you loan someone this tool, loan them these instruc-
tions also.
A
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 and cement and other masonry products, and
arsenic and chromium from chemically-treated lumber.
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.
