SAFETY INSTRUCTIONS

SAFETY INSTRUCTIONS cont.

WARNING: BE SURE to read and understand all instructions in this manual

before using this circular saw. Failure to follow all instructions may result in hazardous radiation exposure, electric shock, fire and/or serious personal injury.

WORK AREA SAFETY

1. Keep your work area clean and well lit. Cluttered workbenches 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. Keep bystanders, children and visitors away while operating a power tool. Distractions can cause you to lose control.

4. Make your workshop childproof with padlocks and master switches. Lock tools away when not in use.

5. MAKE SURE the work area has ample lighting so you can see the work and that there are no obstructions that will interfere with safe operation BEFORE using your saw.

PERSONAL SAFETY

1. KNOW your power tool. Read the operator's manual carefully. Learn the saw's applications and limitations, as well as the specific potential hazards related to this tool.

2. STAY ALERT, watch what you are doing and use common sense when operating a power tool.

3. 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.

4. DRESS properly. DO NOT wear loose clothing or jewelry. Pull back long hair. Keep your hair, clothing, and gloves away from moving parts. Air vents often cover moving parts and should also be avoided. Loose clothing, jewelry or long hair can be caught in moving parts.

5. AVOID accidental starting. Be sure switch is in “OFF” position before plugging in. DO NOT carry tools with your finger on the switch. Carrying tools with your finger on the switch or plugging in tools that have the switch in the “ON” position invites accidents.

6. REMOVE adjusting keys or wrenches before turning the tool “ON”. A wrench that is left attached to a rotating part of the tool may result in personal injury.

PERSONAL SAFETY cont.

7. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.

8. ALWAYS SECURE YOUR WORK. Use clamps or a vise to hold work when practical. It is safer than using your hand and frees both hands to operate tool.

9. USE SAFETY EQUIPMENT. Always wear eye protection. Dust mask, non-skid shoes, hard hat, or hearing protection must be used for appropriate conditions.

10. 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 SAFETY

WARNING: BE SURE to read and understand all instructions before

operating this saw. Failure to follow all instructions listed below may result in electric shock, fire and/or serious personal injury.

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 the 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 the 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. 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. NEVER leave the tool running. ALWAYS turn it off. DO NOT leave the tool until it comes to a complete stop.

6. STORE idle tools out of the reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.

7. 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.

8. 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.

9. 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.

SAFETY INSTRUCTIONS cont.

ELECTRICAL SAFETY

WARNING: Do not permit fingers to touch the terminals of plug when

installing or removing the plug from the outlet.

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. This circular saw is

a double insulated tool.

WARNING: Double insulation DOES NOT take the place of normal safety

precautions when operating this tool.

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. 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. DO NOT expose power tools to rain or wet conditions or use power tools in wet or damp locations. Water entering a power tool will increase the risk of electric shock.

6. INSPECT tool cords for damage. Have damaged tool cords repaired at a Sears Service Center. BE SURE to stay constantly aware of the cord location and keep it well away from the moving blade.

7. DO NOT abuse the cord. NEVER use the cord to carry the tool by 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.

Cover of Grounded Outlet Box

EXTENSION CORDS Use a proper extension cord. ONLY use cords listed by Underwriters Laboratories (UL).

Other extension cords can cause a drop in line voltage, resulting in a loss of power and overheating of tool. For this tool an AWG (American Wire Gauge) size of at least 14-gauge is recommended for an extension cord of 25-ft. or less in length. Use 12-gauge for an extension cord of 50-ft. Extension cords 100-ft. or longer are not recommended. Remember, a smaller wire gauge size has greater capacity than a larger number (14-gauge wire has more capacity than 16-gauge wire; 12-gauge wire has more capacity than 14-gauge). When in doubt use the smaller number. When operating a power tool outdoors, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric shock.

CAUTION: 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.

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.

SAFETY INSTRUCTIONS cont.

SAFETY RULES FOR CIRCULAR SAWS

DANGER:

Keep hands away from cutting area and blade. Keep your

second hand on the auxiliary handle or motor housing. If both hands are holding the saw, the blade cannot cut them.

CAUTION: Blades coast after saw is switched off.

1. KEEP your body positioned to either side of the saw blade and not in direct 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 18 and 19).

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

DANGER:

When sawing through a workpiece, the lower blade guard DOES

NOT cover the blade on the underside of the workpiece (Pg. 17 Fig. 4). ALWAYS keep your hands and fingers away from the cutting area.

3. 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 lever. The guard is operating properly when it moves freely, does not touch the blade or any other part in all angles and depths of cut, and readily returns to the closed position.

4. 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. DO NOT operate your saw until the damage has been repaired or replaced.

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 its lever. 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 workpiece properly in order to minimize body exposure, blade binding, or loss of control.

8. HOLD TOOL by insulated gripping surfaces (handles) 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. ALWAYS clamp the workpiece securely so it will not move when making the cut.

10. 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.

11. 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 cause loss of control.

SAFETY RULES FOR CIRCULAR SAWS cont.

11. 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 cause loss of control.

12. NEVER use damaged or incorrect blade washers or bolts. The blade washers and bolts were specially designed for your saw, for optimum performance and safety of operation.

13. NEVER cut more than one piece at a time. DO NOT STACK more than one

workpiece on the worktable at a time.

14. AVOID awkward operations and hand positions where a sudden slip could cause your hand to move into the blade.

15. NEVER reach into the cutting path of the blade.

WARNING:

WARNING: Some dust created by using power tools contains chemicals known to the State of California to cause cancer and 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.

• Arsenic and chromium, from chemically treated lumber.

Your risk from these exposures varies, depending upon how often you do this type of work. To reduce your exposure to these chemicals:

• Work in a well-ventilated area.

• Work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmful chemicals.

WARNING: Use of this tool can generate and/or disburse dust, which may

cause serious and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection appropriate for the dust exposure. Direct particles away from face and body.

ADDITIONAL RULES FOR SAFE OPERATION

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.

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.

3. PROTECT your lungs. Wear a face mask or dust mask if the operation is dusty.
