SAVETHESE INSTRUCTIONS! READ ALL INSTRUCTIONS!

Failure to follow all instructions listed below may result in electric

WARNING: BE SURE to read and understand all instructions. J

WORK AREA SAFETY

1. ALWAYS keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.

2. 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.

3. ALWAYS keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

1. 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.

2. Double insulation [] eliminates the need for the three-wire grounded power

cord and grounded power supply system. Applicable only to Class II

(double insulated) tools.

3. Before plugging in the tool, RE SURE that the outlet voltage supplied is

within the voltage marked on the tool's data plate. DO NOT use "AC only"

rated tools with a DC power supply.

4. ALWAYS 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.

5. If operating the power tool in damp locations is unavoidable, ALWAYS use a Ground Fault Circuit Interrupter to supply power to your tool.

ALWAYS wear electrician's rubber gloves and footwear in

damp conditions,

6. DO NOT expose power tools to rain or wet conditions. Water entering

a power tool will increase the risk of electric shock.

7. DO NOT abuse the cord. NEVER use the cord to carry the tools or pull

the plu.g from the outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately.

Damaged cords increase the risk of electric shock.

Ishock, fire and/or serious personal injury.

ELECTRICAL SAFETY cont.

8. When operating a power tool outside, ALWAYS use an outdoor extension cord marked "W-A" or "W". These cords are rated for outdoor use and

reduce the risk of electric shock.

NOTE: The extension cord must have adequate wire size AWG (American Wire Gauge) for safe, efficient use. Smaller gauge wires, have greater capacity (1 6 gauge wire has more capacity than 18 gauge wire).

PERSONAL SAFETY

1. ALWAYS 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.

2. ALWAYS dress properly. DO NOT wear loose clothing or jewelry. Pull

back long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.

3. ALWAYS 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 in the "On" position invites accidents.

4. ALWAYS 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.

5. DO NOT overreach. ALWAYS keep proper footing and balance at all

times. Proper footing and balance enables better control of the tool in

unexpected situations.

6. ALWAYS use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hardhat, or hearing protection must be used for appropriate conditions.

TOOL USE AND CARE SAFETY

1. ALWAYS use clamps or other practical ways 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.

2. DO NOT force tool. Use the correct tool and blade for your application. The correct tool and blade will do the job better and safer at the rate for which

it is designed.

3. 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.

4. ALWAYS disconnect the plug from the power source before making any adjustments, changing accessories,or storing the tool. Such preventive

safety measures reduce the risk of starting the tool accidentally.

5. ALWAYS store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.

6. ALWAYS 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.

7. ALWAYS 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.

RECOMMENDED FOR USE WITH THIS TOOL MAY CREATE

I WARNING: USE OF ACCESSORIES THAT ARE NOT

A HAZARDOUS CONDITION.

8. ALWAYS use only accessories that are recommended for this tool. Accessories that may be suitable for one tool may become hazardous

when used on another tool.

SERVICE SAFETY

1.Tool service MUST BE performed only by Sears or other qualified repair

personnel. Service or maintenance performed by unqualified personnel could

result in a risk of injury.

2. When servicing a tool, ALWAYS 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.

SAFETY RULES FOR CIRCULAR SAWS

Z_ DANGER! Keep hands away from cutting area and blade. I Keep your second hand on the auxiliary handle or motor housing.

If both hands are holding the saw, they cannot be cut by the blade.

1. ALWAYS keep your body positioned to either side of the saw blade, but not in line with the saw blade. Kickback could cause the saw to jump

backwards. (See Kickback...What Causes It and Ways to Prevent It on pages 7-8).

2. DO NOT reach underneath the work. The guard cannot protect you from the blade beneath the work.

3. ALWAYS check lower guard for proper closing BEFORE each use.

DO NOT operate the saw if the lower guard does not move freely and

close instantly. Never clamp or tie the lower guard in the open position.

If the saw is accidentally dropped, the lower guard may be bent. Raise the lower guard with the retracting handle. Make sure that it moves freely and

does not touch the blade or any other part in all angles and depths of cut.

4. ALWAYS check the operation and condition of the lower guard spring.

If the guard and the spring are not operating properly, they MUST be serviced before use. The lower guard may operate sluggishly, due to

damaged parts, gummy deposits, or a buildup of debris.

5.The lower guard should be retracted manually ONLY for making special cuts, such as pocket or compound cuts. ALWAYS raise the lower guard

by retracting the handle. As soon as the blade enters the material, the lower guard MUST be released. For all other sawing, the lower guard

should operate automatically.

6. ALWAYS make sure that the lower guard is covering the blade BEFORE placing the saw down on a work bench or floor. An unprotected moving

blade will cause the saw to walk backwards, cutting whatever is in its path.

Make note of the time it takes for the blade to stop spinning after the

switch is released.

7. NEVER hold the piece being cut in your hands or across your legs.

It is important to support the work properly in order to minimize body

exposure, blade binding, or loss of control.

8. ALWAYS 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 the exposed metal parts of

the tool "live" and shock the operator.

9.When ripping, ALWAYS use a rip fence or straight edge guide. This improves the accuracy of the cut and reduces the chance of the blade binding.

10. ALWAYS use blades that have the correct size and shape (diamond vs. round) arbor holes. Blades that do not match the mounting hardware

of the saw will run erratically and will cause loss of control.

SAFETY RULES FOR CIRCULAR SAWS cont.

11. ALWAYS BE SURE that all adjusting screws and the blade holder are fastened tightly BEFORE making a cut. Loose adjusting screws and holders can cause the tool or blade to slip and loss of control may result.

12. When removing the blade from the tool, ALWAYS avoid contact with skin and ALWAYS wear protective gloves when grasping the blade or accessory.

Accessories may be hot after prolonged use.

KICKBACK...WHAT CAUSES IT AND WAYS TO PREVENT IT

The Causes of Kickback

1. Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, which causes the uncontrolled sawto lift up and out of the workpiece and

towards the operator.

2. When the blade is pinched or bound tightly by the kerr closing down, the

blade stalls and the motor reaction drives the unit rapidly back towards

the operator.

3. If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood. This causes the

blade to climb out of the kerf and jump back towards the operator.

4. Kickback is a result of toot misuse and/or incorrect operating procedures or conditions. It can be avoided by taking the proper precautions, as listed betow.

Ways to Prevent Kickback

1. ALWAYS maintain a firm grip with both hands on the saw and position your body and arms to allow you to resist KICKBACK forces.

KICKBACK forces can be controlled by the operator, if the proper precautions are taken.

2. If the blade is binding, or when you are interrupting a cut for any reason, ALWAYS release the trigger and hold the saw motionless in

the material until the blade comes to a complete stop. NEVER attempt to remove the saw from the work or pull the saw backward while the

blade is in motion or KICKBACK may occur. ALWAYS check and be ready to take corrective action to eliminate the cause of blade binding.

3. When restarting the saw in the workpiece, ALWAYS center the blade

in the kerf and check to be sure that the saw teeth are not engaged into the material. If the saw blade is binding, it may walk up or KICKBACK

from the workpiece when the saw is restarted.

4. ALWAYS support large panels to minimize the risk of blade pinching

and KICKBACK. Large panels tend to sag under their own weight. Supports MUST be placed under the panel on both sides, near the line

of cut and near the edge of the panel.

Ways to Prevent Kickback cont.

5. DO NOT use a dull or damaged blade. Unsharpened or improperly set blades produce narrow kerr which causes excessive friction, blade binding and KICKBACK.

6. ALWAYS be sure that the blade depth and adjusting locking levers are tight and secure BEFORE making a cut. Ifblade adjustment shiftswhile

cutting, it may cause binding and KICKBACK.

7. ALWAYS use extra caution when making a "Pocket Cut" into existing walls or other blind areas. The protruding blade may cut objects that

can cause KICKBACK.

8. ALWAYS have saw blade at full speed before contacting workpiece.

ALWAYS 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 the exposed metal parts of the tool

"live" and shock the operator.

ADDITIONAL RULES FOR SAFE OPERATION

Failure to follow all instructions listed below may result in electric shock,

WARNING: BE SURE to read and understand all instructions. I

fire and/or serious personal injury.

1. Know your power tool. Read operator's manual carefully. Learn the

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.

2. ALWAYS wear safety glasses or eye shields when using this saw. Everyday eyeglasses have only impact-resistant lenses; they are

NOT safety glasses. Following this rule will reduce the risk of serious personal injury.

3. ALWAYS protect your lungs.Wear a face mask or dust mask if the operation is dusty. Following this rule will reduce-the risk of serious

personal injury.

4. ALWAYS protect your hearing. Wear hearing protection during

extended periods of operation. Following this rule will reduce the risk

of serious personal injury.

5. ALWAYS inspect the tool cords periodically and if damaged have them repaired at your nearest Sears Service Center or other Authorized

Service Facility. ALWAYS be aware of the cord location. Following this rule will reduce the risk of electric shock or fire.

ADDITIONAL RULES FOR SAFE OPERATION cont.

6. ALWAYS check for damaged parts. Before further use of the tool, a

guard or other part that is damaged should be carefully checked to determine if it will operate properly and perform its intended function.

Check for misalignment or binding of moving parts, breakage of parts

and any other condition that mayaffect the tool s operation. A guard or other part that is damaged, should be properly repaired or replaced at

a Sears Service Center. Following.this rule will reduce the risk of

electric shock, fire or serious injury.

7. DO NOT abuse the cord. NEVER use the cord to carry the tool or pull the plug from the outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock. Following this rule will reduce the risk of

electric shock or fire.

8. ALWAYS make sure that your extension cord is in good condition.

When using an extension cord be sure to use one that is heavy

enough to carry the current that your tool will draw. A wire gauge size (A.W.G.) of at least 16 is recommended for an extension 100 feet

or less in length. Using an extension cord that is over 100 feet in length is not recommended. If in doubt, use the next heavier gauge.

Smaller gauge wires, have greater capacity (16 gauge wire has more capacity than 18 gauge wire). An undersized cord wiLl cause a drop in

line voltage, resulting in loss of power and overheating.

9. ALWAYS inspect and remove all nails from lumber before sawing. Following this rule will reduce the risk of serious personal injury.

10. DO NOT use the tool while tired or under the influence of drugs, alcohol or any medication. Following this rule will reduce the risk of

electric shock, fire or serious personal injury.

11. SAVE THESE INSTRUCTIONS. Refer to them frequently and use them to instruct others who may use this tool. If someone borrows this tool, make sure they have these instructions also.

/iX WARNING: The operation of any circular

saw can result in foreign objects being thrown into your eyes, which can result in severe eye damage. Before beginning power toot operation, ALWAYS wear safety goggles or safety glasses with side shield and a full

face shield when needed. We recommend AWide Vision Safety Mask for use over eyeglasses or

standard safety glasses with side shield, available at Sears Retail Stores.
