EXTENSION CORDS  
ELECTRICAL SAFETY  
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.  
!
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

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.  
SERVICE SAFETY  
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.  
1. If any part of this saw is missing or should break, bend, or fail in any way;  
or should any electrical component fail to perform properly: SHUT OFF the power  
switch and remove the saw plug from the power source and have the missing, damaged  
or failed parts replaced BEFORE resuming operation.  
2. Tool service must be performed only at a Sears Parts and Repair Center. Service or  
maintenance performed by unqualified personnel could result in a risk of injury.  
3. 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 electric shock or injury.

SAFETY RULES FOR CIRCULAR SAWS  
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.  
!
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.  
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.  
!
CAUTION: Blades coast after saw is switched off.  
13. NEVER cut more than one piece at a time. DO NOT STACK more than one  
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).  
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.  
2. DO NOT reach underneath the work. The guard cannot protect you from the blade  
15. NEVER reach into the cutting path of the blade.  
beneath the workpiece.  
!
WARNING: WARNING: Some dust created by using power tools contains  
!
DANGER:  
When sawing through a workpiece, the lower blade guard DOES  
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.  
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.  
• Crystalline silica from bricks and cement and other masonry products.  
• Arsenic and chromium, from chemically treated lumber.  
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.  
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.  
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.  
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.  
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.  
ADDITIONAL RULES FOR SAFE OPERATION  
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.  
!
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.  
9. ALWAYS clamp the workpiece securely so it will not move when making the cut.  
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.  
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.  
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.

when making  
a cut  
All saw blades need to be  
kept clean, sharp and properly  
set in order to cut efficiently.  
Using a dull blade places a  
heavy load on the saw and  
increases the danger of  
kickback. Keep extra blades on  
hand, so sharp blades are  
always available. Gum and  
wood pitch hardened on the  
blade slows the saw down.  
Use gum and pitch remover,  
hot water or kerosene to  
remove them. DO NOT use  
gasoline.
