GENERAL SAFETY RULESGENERAL SAFETY RULES
WARNING:
Read and understand 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 atmospheres,
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 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
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 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.
eliminates the need for the three-
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
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 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.
Keep the tool and its handle dry, clean and free from
oil and grease. Always use a clean cloth when clean-
ing. 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.

GENERAL SAFETY RULES
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.
WARNING:
To reduce the risk of injury, user must read
instruction manual.
SPECIFIC SAFETY RULES
Hold power tools 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 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 eye protection with side shields marked
to comply with ANSI Z87.1. 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 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
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
shock or injury.
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.
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 product
will draw. A wire gauge size (A.W.G.) of at least 16 is
recommended for an extension cord 50 feet or less
in length. A cord exceeding 100 feet is not recommended. 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 voltage 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.
If the power supply cord is damaged, it must be replaced
only by the manufacturer or by an authorized service
center to avoid risk.
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.

ELECTRICAL
DOUBLE INSULATION
Double insulation is a concept in safety in electric power
tools, which eliminates the need for the usual three-wire
grounded power cord. All exposed metal parts are isolated
from the internal metal motor components with protecting
insulation. Double insulated tools do not need to be
grounded.
WARNING:
The double insulated system is intended to protect
the user from shock resulting from a break in the
tool’s internal wiring. Observe all normal safety
precautions to avoid electrical shock.
NOTE: Servicing of a tool with double insulation requires
extreme care and knowledge of the system and should
be performed only by a qualified service technician. For
service, we suggest you return the tool to your nearest
authorized service center for repair. Always use original
factory replacement parts when servicing.
ELECTRICAL CONNECTION
This tool has a precision-built electric motor. It should
be connected to a power supply that is 120 V, AC only
(normal household current), 60 Hz. Do not operate this tool
on direct current (DC). A substantial voltage drop will cause
a loss of power and the motor will overheat. If the tool does
not operate when plugged into an outlet, double-check the
power supply.
EXTENSION CORDS
When using a power tool at a considerable distance from
a power source, be sure to use an extension cord that has
the capacity to handle the current the product will draw. An
undersized cord will cause a drop in line voltage, resulting in
overheating and loss of power. Use the chart to determine
the minimum wire size required in an extension cord. Only
round jacketed cords listed by Underwriter’s Laboratories
(UL) should be used.
When working outdoors with a product , use an extension
cord that is designed for outside use. This type of cord is
designated with “W-A” or “W” on the cord’s jacket.
Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.

WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on
lumber, tools or other obstructions while you are
working with a power tool. Failure to do so can
result in serious personal injury.
WARNING:
Check extension cords before each use. If
damaged replace immediately. Never use tool with
a damaged cord since touching the damaged area
could cause electrical shock resulting in serious
injury.
