This tool has many features for making its use more pleasant and enjoyable. Safety, performance, and dependability have been given top priority in the design of this product making it easy to maintain and operate.

_h 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 the work area clean and well lit. Cluttered benches and dark areas invite accidents.

• Do not operate power tools in explosive atmo-

spheres, such as in the presence of flammable liq-

uids, 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 polar- ized 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 the body is ground- ed.

• 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 com- mon 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 the 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 the 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 the body is unstable and

may lead to loss of control.

• Do not force tool. Use the correct tool for the appli-

cation. 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 cut- ting 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 the 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 cleaning. Never use brake fluids, gasoline, petroleum-

based products, or any strong solvents to clean the

tool. Following this rule will reduce the risk of loss of control and deterioration of the enclosure plastic.

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.

• When servicing a tool, use only identical replace- ment 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.

• 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 cut- ting tool "live" and shock the operator.

• Know the 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.

• 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 the lungs. Wear a face or dust mask if the operation is dusty. Following this rule will reduce the

risk of serious personal injury.

• Protect the 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 the nearest Authorized Service

Center. Constantly stay aware of cord location. Fol-

lowing 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 op-

erate 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 opera- tion. 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 the extension cord is in good condition.

When using an extension cord, be sure to use one

heavy enough to carry the current the 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 recom-

mended. 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 volt- age 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.

• 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 instruc- tions 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. The risk from these exposures varies, depending on how often you do this type of work. To reduce the 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.
