,_ WARNING: Read and follow 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 accidents.
Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases, or dust. Power tools may 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 pads.
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
common sense when operating a power tool. Do
not use tool while tired or under the influence of
drugs, alcohol, or medication. A moment of inatten-
tion 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.

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 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 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 inthe
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 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
repair personnel. Service or maintenance performed
by unqualified personnel could result in a risk of injury.
• When servicing a tool, use only identical replace-
ment 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 Rules For Safe Operation
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
during 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 Factory Service
Center or other Authorized Service Organization.
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 function.
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
service center. Following this rule will reduce the risk
of shock, fire, or serious injury.
Do not abuse cord. Never carry the tool by the cord
or yank it to disconnect it from the receptacle.
Keep cord away from heat, oil, and sharp edges.
Following this rule will reduce the risk of electric shock
or fire.
Make sure your extension cord is in good condi-
tion. When using an extension cord, be sure to use
one heavy enough to carry the current your prod-
uct will draw. Awire gage size (A.W.G.) of at least
16 is recommended for an extension cord 100 feet
or less in length. A cord exceeding 100 feet is not
recommended. If in doubt, use the next heavier
gage. The smaller the gage number, the heavier the
cord. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating.
Inspect for and remove all nails from lumber before
drilling. Following this rule will reduce the risk of
serious personal injury.
Drugs, alcohol, medication. Do not operate tool
while under the influence of drugs, alcohol, or any
medication. Following this rule will reduce the risk of
electric shock, fire, or serious personal injury.
Save these instructions. Refer to them frequently
and use them to instruct others who may use this
tool. If you loan someone this tool, loan them these
instructions also.
,_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.
