FORESIGHT IS BETTER
GLASSES
THAN NO SIGHT
Look for this symbol to point out important safety
precautions. It means attention!!! Your safety is involved.
The operation of any power tool can result in foreign objects being thrown into your eyes,
which can result in severe eye damage. Before beginning tool operation, always wear safety
goggles or safety glasses with side shields and a full face shield when needed. We
recommend Wide Vision Safety Mask for use over eyeglasses or standard safety glasses
with side shields. Always wear eye protection which is marked to comply with ANSI Z87.1.

GENERAL SAFETY RULES
SAVE THESE INSTRUCTIONS
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 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 insu-
lation 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 moment of inat-
tention 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 or drawn into air vents.
■ 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 at-
tached 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 en-
ables better control of the tool in unexpected situations. Do not use on a ladder or unstable support.
■ 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 other practical way to secure and
support the workpiece to a stable platform. Hold-
ing 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 mea-
sures 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. Accessories 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 per-
formed 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 tool may contact
wiring or its cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.
ADDITIONAL SAFETY RULES
■ 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 re-
duce the risk of serious personal injury.
■ Protect your lungs. Wear a face or dust mask if
the operation is dusty. Following this rule will re-
duce 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. Follow-
ing 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 elec-
tric 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 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 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.
