Inspection/setup
1. Read and fully understand this manual, the safety intructions in particular, and the motor manufacturer's manual supplied with the saw.
2.Select the correct blade for each application. If abrasive blades are used, MAKE CERTAIN they are designed for use on a concrete floor saw.They must be reinforced and have a hole for the driving pin. When wet cutting with an abrasive blade, MAKE CERTAIN the blade is intended for wet cutting. Water will destroy a dry cut abrasive blade. Some diamond blades require water cooling and failure to do so will destroy them almost immediately. Other diamond blades can be used with or without water. Refer to the Blades and Blade Placement sections in this manual for further information.
3.Handle all blades with care and NEVER use a damaged blade. NEVER use an abrasive blade that has been dropped.
Electric Motor
1.The motor should be connected to a power source in compliance with all local electrical codes. This must be performed by a qualified electrician. After this connection is made, it will be necessary to check the rotation of the motor shaft. The shaft rotation MUST be
2.MAKE CERTAIN the rated line voltage is at the motor when cutting. Motors can burn out when the voltage falls 10% below the voltage rating of the motor. Also use the correct heavy duty circuit breakers or fuses in the circuit.
3.MAKE CERTAIN the correct size extension cord is used. Undersize wires will burn out motors. Use the following chart to determine the extension cord size.

WARNING
ALWAYS use a grounded extension cord and make certain the motor is connected to a properly grounded electrical circuit to protect the operator from possible electric shock.
DANGER
ALWAYS use a grounded
NEVER touch the power cord with wet hands or while standing in water when it is connected to a power source. The possibly exists of electrical shock (electrocution) or even death. NEVER spray water directly on the electric motor.
Guards And Covers
WARNING
NEVER operate the saw without blade guards and covers in place. DO NOT operate with the front of the blade guard raised. The blade exposure cannot exceed 180 degrees during operation. Adhere to the safety guidelines of the American National Standards
Institute (ANSI) B7.1 and B7.5.
