Blade Safety Brochure

22 CAUSE: Lack of sufficient coolant to the blade. Often detected by excessive wear in the centre of the segment. (NOTE: In both cases, diamonds will be highly exposed). REMEDY: Clean the water system, checking the pump works correctly. CAUSE: Wearing out-of-round accelerates wear. Usually caused by bad bearings, worn shaft or using a blade too hard for material. REMEDY: Check bearings and arbour. If worn, replace with new parts before operating. CAUSE: Insufficient power caused by loose V-belts, inadequate voltage or improper RPM’s. REMEDY: Tighten belts (taut). Replace worn belts. Check voltage. Use proper size extension cord. Long leads or incorrect cable diameter cause power drop off.

Blade Won’t Cut CAUSE: Blade is too hard for material being cut. REMEDY: Consult dealer or factory for proper blade to cut materials on the job. CAUSE: Insufficient power to permit blade to cut properly (loose V-belts, low voltage, horsepower). REMEDY: Check belts, voltage, and horsepower. CAUSE: Blade has become dull because of continuous use on fairly hard or vitrified material. REMEDY: Dress with abrasive material until diamonds are exposed again. (This may be needed occasionally, if it is often occurring blade is probably too hard, particularly in hard porcelain types due to density and extreme hardness of the product). Use a very fine sharpening block made from aluminium oxide, abrasive sandstone or gritty fine red brick.

Cracked Blank/Core CAUSE: Blade too hard for material being cut. REMEDY: Use correct blade with softer bond.

CAUSE: Excessive cutting pressure, or jamming or twisting the blade in the cut can cause the blade core to bend or flex. When subjected to extreme stress and metal fatigue, the blade’s steel core. REMEDY: Reduce downward pressure, let the diamonds do the work.
