SAVETHESE INSTRUCTIONS!

READ ALL INSTRUCTIONS!

/_, WARNING: BE SURE to 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 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 tne 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, BE 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 plug from the outlet. Keep cord away from heat, od, sharp edges

or moving parts. Replace damaged cords immediately.

Damaged cords increase the risk of electric shock.

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 (16 gauge w re has more capacity than !8 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 fin_er 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 protechon must be used for appropriate conditions.

TOOLUSEANDCARESAFETY

1.ALWAYSuseclamps or other practical ways to secure and support the workplece to a stable platform. Holdingtheworkbyhandor againstyour

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

itis 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

/iN WARNING: USE OF ACCESSORIES THAT ARE NOT I

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.

SAFETYRULESFORCIRCULARSAWS

Keep your second hand on the auxihary handle or motor housing.

I Z_ DANGER! Keep hands away from cutting area and blade. I

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.

_fthe saw is accidentally dropped, the _ower 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

_lacing the saw down on a work bench or floor. An unprotected moving

Lade 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 performin,g

an operation where the cutt!ng 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 a.diustingscrews and the blade holderare 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 oraccessory. 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 saw to lift up and out of the workpiece and towards the operator.

2. When the blade is pinched or bound tightly by the kerf 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 diginto the top surface of the wood. This causes the

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

4. Kickback is a result of tool misuse and/or incorrect operating procedures or

conditions. It can be avoided by taking the proper precautions, as listed below.

Ways to Prevent Kickback

1. ALWAYS maintain a firm grip with both hands on the saw and position

_OcUrbody and arms to allow you to resist KICKBACK forces.

KBACK 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 kerr and check to be sure that the saw teeth are not engaged into the material. It 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.

Waysto Prevent Kickback cont.

5.DONOTuse adull or damaged blade.Unsharpenedor improperlyset

blades produce narrow kerf which causes excessive friction, blade bindingand KICKBACK.

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