Diamond Blade Troubleshooting Guide
SHORT LIFE
CAUSES
REMEDIES
Using the wrong blade on a specific material. A blade specifically designed and manufactured for cutting tiles will wear out extremely fast if used on highly-abrasive material such as block.
Avoid using general purpose specifications for cutting a single specific material. General purpose diamond blades are designed to cut a wide range of materials. Since it is unlikely an operator will be cutting an equal amount of both hard and soft materials at all times, this is not the most economical method of cutting. Make sure water hoses are clean and free from any blockages. Approximately nine litres of water per minute are required to properly cool a masonry saw blade. On concrete saws, 9-22 litres per minute are required.
Inadequate water is supplied to the blade.
Bad spindle bearings, worm mounting arbor, or misaligned shaft.
Loss of power, resulting from loose drive belts or improper voltage.
Replace defective parts.
See machine manual for proper belt tightening, replace worn belts, make sure proper line voltage is being supplied to the motor.
Blade is too hard for material being cut.
Select the proper blade specification for the material being cut. Consult blade recommendation chart. Dress or sharpen with mortar droppings or by cutting a lightweight abrasive building block to expose diamonds. If continual dressing is required, the blade specification is too hard for the material being cut. First, make sure the blade is correct according to the blade recommendation chart. If the blade is correct, allow it to dress itself on the material to be cut. If it does not dress itself, sharpen it as you would a dull blade, according to the procedure described above. Tighten belts in accordance with machine maintenance instructions. Use correct voltage at motor and adequate horsepower for cutting application.
BLADE WILL NOT CUT
Blade has become dull as a result of being used on too hard a material. Blade does not cut material it was specified for. Insufficient power, not allowing blade to cut properly. Often, the blade will stall in the cut.
