SAVETHESEINSTRUCTIONS
Work Area
• Keep your work area clean and well lit. Clut-
tered 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
create sparkswhich may ignitethe dust or fumes.
• Keep bystanders, children, and visitors away
while operating a power tool. Distractionscan
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 refrigera-
tors. There is an increased risk of electric shock if
your body is grounded.
• Don't expose power tools to rain or wet condi-
tions. 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 immedi-
ately. Damaged cords increase the riskof electric
shock.
When operating a power tool outside, use an
outdoor extension cord marked "W-A" or "W."
These cords are rated for outdooruse and reduce
the risk of electricshock.
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 influ-
ence 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 longhaircan be caught
in moving parts.
Avoid accidental starting. Be sure switch is off
before plugging in. Carrying toolswith your
finger on the switch or plugging in toolsthat have
the switch on invitesaccidents.
• 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 toolmay result in
personal injury.
• Do not overreach. Keep proper footing and
balance at all times. Proper footing and balance
enables better control of the toolin unexpected
situations.
• Use safety equipment. Always wear eye protec-
tion. Dust mask, nonskid safety shoes, hard hat,
or hearing protection must be used for appropriate
conditions.
Tool Use and Care •
• Use clamps or other practical way to secure
and support the workpiece to a stable plat-
form. 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 Service
• 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 injury.
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 condi-
tion that may affect the tool's operation. If
damaged, have the tool serviced before using.
Many accidentsare caused by poorly maintained
tools.
Use only accessories that ere recommended
by the manufacturer for your model. Accesso-
des that may be suitable for one tool may become
hazardous when used on another tool.
Tool service must be performed only by quali-
fied 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
unauthorizedparts or failure to follow Maintenance
Instructions may create a risk of electric shock or

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 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 eye-
glasses 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 s 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 dam-
aged, 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 pads,
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.
Don't 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
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 end 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, orserious 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.
