GENERAL SAFETY RULES
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
atmospheres, 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
polarized 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
common sense when operating a power tool.
Do not use tool while tired or under the influence of drugs, alcohol, or medication. A mo-
ment 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.
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 the power source
before making any adjustments, changing
accessories, or storing the tool. Such preven-
tive 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 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. Accesso-
ries that may be suitable for one tool may become
hazardous when used on another tool.

GENERAL SAFETY RULES
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
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.
SPECIFIC SAFETY RULES
Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may
■
contact hidden wiring or its cord. Contact with a "live" wire will make exposed metal parts of the tool "live"
and shock the operator.
Additional Rules for Safe Operation
■ Know your power tool. Read owner'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. Follow-
ing this rule will reduce the risk of serious personal injury.
■ Inspect tool cords periodically and, if damaged, have repaired at your nearest Authorized 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
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 electric
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 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 sanding. 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 chemicallytreated 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.
