TROUBLESHOOTING

periodically with an electronic tachometer to ensure proper operational speed for the blade.

UNEVEN SEGMENT WEAR

a)If wet sawing, insufficient water flow to one side of the blade which effectively reduces the side clearance. Flush the water system. Determine that water is being adequately and equally distributed to both sides of the blade.

b)Worn machine components. Determine that machine components, including bearings, belts and the arbor shaft are not excessively worn and requiring replacement. Determine that the engine runs smoothly to prevent harmonic vibrations which can result in the blade impacting the work surface with impulse type loads.

c)Saw head is misaligned. Periodically check saw head for squareness in both vertical and horizontal planes.

SEGMENT CRACKS

a)Blade matrix composition is too hard for the material being sawed. Utilize a blade with a softer matrix composition.

SHORT BLADE SERVICE LIFE

a)Utilizing the improper blade for sawing a specific material. Avoid the use of a general purpose blade for sawing a single specific material. General purpose blades are intended to saw a wide range of materials. Since it is unlikely that the machine will saw the proper amount of both hard and soft materials proportionately at all times, this type of blade is not the most economical method of sawing. Use a blade with the matrix composition designed specifically for the material and aggregate being sawed.

b)While wet sawing, improper water flow is being delivered to both sides of the blade. Determine that all water hoses are clean and free of any internal blockage. Approximately two to five gallons of water per minute are required to properly cool a blade.

c)Worn machine components. Determine that machine components including bearings, belts and the arbor shaft are not excessively worn and requiring replacement. Determine that the engine runs smoothly to prevent harmonic vibrations which can result in the blade impacting the work surface with impulse type loads.

d)Loss of power, resulting from improper engine RPM speed, electric motor voltage or loose V-belts. See Service section.

BLADE WILL NOT CUT

a)Blade matrix composition is too hard for the material being sawed. Utilize a blade with a softer matrix composition.

b)Blade has become dull, probably as a result a hard matrix composition being utilized to saw a hard material. Dress or sharpen the blade by utilizing it to saw a softer material to expose new diamonds in the segments. If continual dressing is required, it would indicate that the blade matrix composition is too hard for the material being sawed.

c)Failure to initially break in a new blade on a specific material being cut. Allow the blade to sharpen itself on the material to be sawed when first placing it on the Crack Saw. This is the proper method to break in a new blade. Do not force the new blade into a cut as this will generally aggravate the problem.

d)Loss of power, resulting from improper engine RPM speed, electric motor voltage or loose V-belts. See Service section.

e)When dry sawing, the blade becomes dull as a result of overheating, allowing the segment rim to "mushroom" or melt. Discontinue usage and contact the diamond blade manufacturer.

BLADE BLANK WARPAGE

a)The blade blank has been overheated. While wet sawing, improper water flow is being delivered to both sides of the blade. Determine that all water hoses are clean and free of any internal blockage.

b)The blade blank has been overheated. While dry sawing, periodically allow the blade to run out of the cut for up to 20 seconds for every minute sawing. This procedure will allow the blade to cool in a few seconds and allow the sawing process to proceed. If the blade has been warped (dark blue color), it may be damaged beyond repair. A blade in this condition should be discontinued from use immediately and properly discarded.

c)The blade blank has been overheated as a result of spinning on the arbor shaft. Check the arbor shaft, hub body and hub flange for excessive wear and/or damage. Properly tighten the arbor shaft nut.

d)Unequal flange clamping forces. The hub body flange and hub flange must be of the same, identical diameter. Always replace any questionable component with a factory replacement part only.
