Do not hold it, clamp it, touch it or use a length stop against it. The cut-off waste portion must be free to move. It could become wedged against the disc causing a hazard.



In the event of a malfunction or breakdown, grounding provides the path of least resistance for electric current and reduces the risk of electric shock. This tool is equipped with an electric cord that has an equipment grounding conductor and a grounding plug. The plug MUST be plugged into a matching receptacle that is properly installed and grounded in accordance with ALL local codes and ordinances.


• Use only manufacturer’s recommended replacement parts, or equivalent, when servicing this tool.

• Do not touch the metal blades on the power cord plug when removing or installing the plug into an electrical outlet.

• To avoid electrical hazards, fire hazards, or damage to the

Improper connection of the equipment grounding conductor can result in risk of electric shock. The conductor with the green insulation (with or without yellow stripes) is the equipment grounding conductor.

tool, use proper circuit protection. Your saw is wired at the factory for 120V operation. Connect to a 120V, 15 Amp time delayed fuse or circuit breaker. To avoid shock or fire, replace power cord immediately if it is worn, cut, or damaged in any way.

If repair or replacement of the electric cord or plug is necessary, DO NOT connect the equipment grounding conductor to a live terminal.

Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be protected with a 15 Amp time delayed fuse. Before connecting the motor 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.

Check with a qualified electrician or service personnel if you do not completely understand the grounding instructions, or if you are not sure the tool is properly grounded.

WARNING: This saw is for indoor use only. Do not expose to rain or use in damp locations. This tool must be grounded while in use to protect the operator from electrical shock.

Do not modify the power cord plug. If it does not match the electrical outlet, have the proper outlet installed by a qualified electrician. This tool is intended for use on a circuit that has a receptacle like the one illustrated: a 3-prong electrical plug (1) and a receptacle (2) that has a grounding conductor. If a properly grounded receptacle is not available, have a certified electrician check the receptacle.




SAFETY Use only 3-wire extension cords that have 3-prong plugs and 3-prong outlets that accept the tool’s plug.

Guidelines for Extension Cords Use 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 cause 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 operating 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. Repair or replace damaged or worn cord immediately.
