POWER TOOL SAFETY
GENERAL SAFETY INSTRUCTIONS BEFORE USING THIS POWER TOOL
Safety is a combination of common sense, staying alert and knowing how to use your power tool.
CAUTION
To avoid mistakes that could cause serious injury, do not plug the tool in until you have read and understood the following.
1. READ and become familiar with the entire Operator’s
Manual. LEARN the tool’s application, limitations and possible hazards.
2.KEEP GUARDS IN PLACE and in working order.
3.REMOVE ADJUSTING KEYS AND WRENCHES. Form the habit of checking to see that keys and adjusting wrenches are removed from the tool before turning ON.
4.KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
5.DO NOT USE IN DANGEROUS ENVIRONMENTS. Do not use power tools in damp locations, or expose them to rain or snow. Keep work area well lit.
6.KEEP CHILDREN AWAY. All visitors and bystanders should be kept a safe distance from work area.
7.MAKE WORKSHOP CHILD PROOF with padlocks, master switches or by removing starter keys.
8.DO NOT FORCE THE TOOL. It will do the job better and safer at the rate for which it was designed.
9.USE THE RIGHT TOOL. Do not force the tool or an attachment to do a job for which it was not designed.
10.USE PROPER EXTENSION CORDS. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will result in
a drop in line voltage and in loss of power which will cause the tool to overheat. The table on page 10 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
11.WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets or other jewelry which may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair covering to contain long hair.
12.ALWAYS WEAR EYE
PROTECTION. Any power tool can throw foreign objects into the eyes and
could cause permanent eye damage. ALWAYS wear Safety Goggles (not glasses) that comply with ANSI Safety standard Z87.1. Everyday eyeglasses have only impact–resistant lenses. They ARE NOT safety glasses. Safety Goggles are available at sears.
5 
NOTE: Glasses or goggles not in compliance with ANSI Z87.1 could seriously injure you when they break.
13.WEAR A FACE MASK OR DUST MASK. Sawing operation produces dust.
14.SECURE WORK. Use clamps or a vise to hold work
when practical. It is safer 
than using your hand and it frees both hands to operate the tool.
15.DISCONNECT TOOLS FROM POWER SOURCE before servicing, and when changing accessories such as blades, bits and cutters.
16.REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in the OFF position before plugging the tool in.
17.USE RECOMMENDED ACCESSORIES. Consult this Operator’s Manual for
recommended accessories. The use of improper accessories may cause risk of injury to yourself or others.
18.NEVER STAND ON THE TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted.
19.CHECK FOR 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 operate 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 operation. A guard or other part that is damaged should be properly repaired or replaced.
20.NEVER LEAVE THE TOOL RUNNING UNATTENDED. TURN THE POWER “OFF”. Do not walk away from a running tool until the blade comes to a complete stop and the tool is unplugged from the power source.
21.DO NOT OVERREACH. Keep proper footing and balance at all times.
22.MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.
23.WARNING: Dust generated from certain materials can be hazardous to your health. Always operate saw in well-ventilated area and provide for proper dust removal.

COMPOUND MITER SAW SAFETY
SPECIFIC SAFETY INSTRUCTIONS FOR THIS COMPOUND MITER SAW
1.DO NOT operate the miter saw until it is completely assembled and installed according to these instructions.
2.IF YOU ARE NOT thoroughly familiar with the operation of miter saws, seek guidance from your supervisor, instructor or other qualified person.
3.ALWAYS hold the work firmly against the fence and table. DO NOT perform any operation free hand (use clamp wherever possible).
4.KEEP HANDS out of the path of the saw blade. If the workpiece you are cutting would cause your hands to be within 6-3/4 in. of the saw blade, the workpiece should be clamped in place before making the cut.
5.BE SURE the blade is sharp, runs freely and is free of vibration.
6.ALLOW the motor to come up to full speed before starting a cut.
7.KEEP THE MOTOR AIR SLOTS CLEAN and free of chips or dust.
8.ALWAYS MAKE SURE all handles are tight before cutting, even if the table is positioned in one of the positive stops.
9.BE SURE both the blade and the collar are clean and the arbor bolt is tightened securely.
10.USE only blade collars specified for your saw.
11.NEVER use blades larger in diameter than 7-1/4 inches.
12.NEVER apply lubricants to the blade when it is running.
13.ALWAYS check the blade for cracks or damage before operation. Replace a cracked or damaged blade immediately.
14.NEVER use blades recommended for operation at less than 5000 RPM.
15.ALWAYS keep the blade guards in place and use at all times.
16.NEVER reach around the saw blade.
17.MAKE SURE the blade is not contacting the workpiece before the switch is turned ON.
18.IMPORTANT: After completing the cut, release the trigger and wait for the blade to stop before returning the saw to the raised position.
19.MAKE SURE the blade has come to a complete stop before removing or securing the workpiece, changing the workpiece angle or changing the angle of the blade.
20.NEVER cut metals or masonry products with this tool. This miter saw is designed for use on wood and wood-like products.
7 
21.NEVER cut small pieces. If the workpiece being cut would cause your hand or fingers to be within 6-3/4 in. of the saw blade the workpiece is too small.
22.PROVIDE adequate support to the sides of the saw table for long work pieces.
23.NEVER use the miter saw in an area with flammable liquids or gases.
24.NEVER use solvents to clean plastic parts. Solvents could possibly dissolve or otherwise damage the material.
25.SHUT OFF the power before servicing or adjusting the tool.
26.DISCONNECT the saw from the power source and clean the machine when finished using.
27.MAKE SURE the work area is clean before leaving the machine.
28.SHOULD any part of your miter saw be missing, damaged, or fail in any way, or any electrical component fail to perform properly, lock the switch and remove the plug from the power supply outlet. Replace missing, damaged, or failed parts before resuming operation.

ELECTRICAL REQUIREMENTS AND SAFETY
POWER SUPPLY AND MOTOR SPECIFICATIONS
The AC motor used in this saw is a universal, nonreversible type. See “MOTOR” in the “PRODUCT
SPECIFICATIONS” section on page 3.
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 the proper outlet. Do not change the plug in any way.
! WARNING
To avoid electrical hazards, fire hazards, or damage to the tool, use proper circuit protection. Your saw is wired at the factory for 120 V operation. Connect to a 120 V, 9A circuit and use a 9 A time delay fuse or circuit breaker. To avoid shock or fire, if power cord is worn or cut, or damaged in any way, have it replaced immediately.
DOUBLE INSULATED 
The power tool is double insulated to provide a double thickness of insulation between you and tool’s electrical system. All exposed metal parts are isolated from the internal metal motor components with protecting insulation.
Replacement parts – When servicing, use only identical replacement parts.
Polarized plugs – This saw has a plug that looks like the one shown below:
To reduce the risk of electrical shock, this saw has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one
! WARNING
Double insulation does not take the place of normal safety precautions when operating this tool.
To avoid electrocution:
1.Use only identical replacement parts when servicing a tool with double insulation. Servicing should be performed by a qualified technician.
2.Do not use power tools in wet or damp locations or expose them to rain or snow.
MOTOR SAFETY PROTECTION IMPORTANT
To avoid motor damage, the motor should be blown out or vacuumed frequently to keep sawdust from interfering with the motor ventilation.
1.Connect this saw to a 120 V circuit. This circuit must not be less than a #18 wire with a 9 A time lag fuse.
NOTE: When using an extension cord on a circuit with a #18 wire, the extension cord must not exceed 25 feet in length.
2.If the motor will not start, release the trigger switch immediately.
UNPLUG THE SAW. Check the saw blade to make sure it turns freely. If the blade is free, try to start the saw again. If the motor still does not start, refer to the TROUBLESHOOTING GUIDE.
3.If the tool suddenly stalls while cutting wood, release the trigger switch, unplug the tool and free the blade from the wood. The saw may
9 
now be started and the cut finished.
4.FUSES may “blow” or circuit breakers may trip frequently if:
a.MOTOR is overloaded – overloading can occur if you feed too rapidly or make too many start/stops in a short time.
b.LINE VOLTAGE is more than 10% above or below the nameplate voltage rating. For
heavy loads, the voltage at motor terminals must equal the voltage specified on the nameplate.
c.IMPROPER or dull saw blades are used.
5.Most motor troubles may be traced to loose or incorrect connections, overload, low voltage or inadequate power supply wiring. Always check the connections, the load and supply circuit if the motor doesn’t run well. Check minimum gauge for the length of cord you are using on the chart below.
GUIDELINES FOR EXTENSION CORDS
Use a proper extension cord. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage, resulting in
loss of power and overheating. The table below shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.
Be sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it. Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #18 wire with a 9 A time lag fuse. NOTE: When using an extension cord on a circuit with a #18 wire, the extension cord must not exceed 25 feet in length. Before connecting the tool to the power line, make sure the switch is in the OFF position and the electric current is rated the same as the current stamped on the motor nameplate, running at a lower voltage will damage the motor.
