Operation:

1. Before a concrete saw is operated, its operation manual should be read and understood, for serious safety issues may happen if the concrete saw is used improperly.

2. The operator the should inspect the saw machine to see if it is in good condition, and do some cleaning work.

3. The operator should check the diamond saw blade.

    1) Drive pin hole. There should be no distortion of the pin hole.

    2) Gullets. Check the steel core of the blade for cracks that may have propagated from the gullets. Cracks indicate extreme fatigue failure and if sawing continues, catastrophic failure will occur.

    3) Edge of the steel core. Check the diameter edge for discoloration (blue oxidation) indicating an overheating condition caused by insufficient cooling water/air. Overheating of blades may lead to loss of core tension and/or increase the possibility for blade failure. Check to make sure the steel core's width is uniform about the rim of the blade, and not succumbing to an "under cutting" condition brought about by highly abrasive material or improper under cutting core protection.

    4) Directional arrow. Check to ensure that the blade is oriented properly. Reference the directional arrow on the blade and place it so the direction of rotation "downcuts" with the turn of the shaft.

    5) Diamond segments or rim. Ensure there are no cracks, dings, or missing portions of the diamond segments or rim. DO NOT use a blade that is missing a segment or a portion of the rim. Damaged and/or missing segments/rims may cause damage to the saw, and injury to the operator or others in the operating area.

    6) Features and specifications. Ensure that the blade' features and specifications properly match the sawing operation. Wet blades must have water to act as a coolant. Utilizing a diamond blade not matched properly to the task may result in poor performance and/or blade damage.

    7) Arbor hole. It is essential that the diameter of arbor hole matches the blade, and that it is free from distortions. Correct blade flanges (collars) must be used. The inside face of the flanges must be clean and free of debris. An out of round arbor condition will cause damage to the blade and the saw.

    8) Maximal RPM. This RPM reference is the maximum safe operating speed for the blade selected. Exceeding the max RPM of the diamond blade is dangerous, and may cause poor performance and may damage the blade.
