GENERAL 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

n Keep your work area clean and well lit. Cluttered

benches and dark areas invite accidents.

n 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.

n Keep bystanders, children, and visitors away while

operating a power tool. Distractions can cause you to

lose control.

n

Av oid accidental star ting . 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.

n 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.

n Do not overreach. Keep proper footing and balance

at all times. Proper footing and balance enables better

control of the tool in unexpected situations.

n Use safety equipment. Always wear eye protection.

Dust mask, nonskid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.

n Do not wear loose clothing or jewelry. Contain long

hair. Loose clothes, jewelry, or long hair can be drawn

into air vents.

n Do not use on a ladder or unstable support. Stable

footing on a solid surface enables better control of the
tool in unexpected situations.

ELECTRICAL SAFETY

n 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.

n 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.

n Don’t expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of electric
shock.

n 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.

n

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

n 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.

n 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.

TOOL USE AND CARE

n 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.

n Do not force tool. Use the correct tool for your appli-

cation. The correct tool will do the job better and safer

at the rate for which it is designed.

n 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.

n 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.

n Store idle tools out of the reach of children and other

untrained persons. Tools are dangerous in the hands of

untrained users.

n 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.

n 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.

n 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.

n 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

n Tool service must be performed only by qualified

repair personnel. Service or maintenance performed by

unqualified personnel may result in a risk of injury.

SPECIFIC SAFETY RULES

n Hold tool 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 cutting
tool “live” and shock the operator.

n Know your power tool. Read operator’s manual care-

fully. 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.

n 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.

n 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.

n Protect your hearing. Wear hearing protection during

extended periods of operation. Following this rule will

reduce the risk of serious personal injury.

n 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.

n 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.

n 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.

n 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 gauge size (A.W.G.) of at least 14 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.

n Inspect for and remove all nails from lumber before

using this tool. Following this rule will reduce the risk of

serious personal injury.

n 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 three­wire 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 insulation. 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 volts, 60 Hz, AC
only (normal household current). 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 your 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 tool 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 tool, use an extension cord
that is designed for outside use. This type of cord is desig­nated with “WA” 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.
