|The blade used is not suitable for the highly abrasive material being cut (e.g: a tile-cutting blade used on a concrete block).
||See the blade selection table or consult your distributor who will indicate the correct blade specification.
|Blade cooling is insufficient; this problem is often found because of excessive wear in the centre of the segment. (Note: in the two cases mentioned above, the diamonds generally project very sharply).
||Clean the cooling system. Ensure that the water pump is operating correctly.
|Wear accelerates if the blade has lost its circular shape; this may be due to poor bearings, a worn spindle or the use of a blade which is too hard in relation to the material being cut.
||Check the bearings and the spindle. If they are worn, replace them before fitting a new blade.
|Output power is insufficient because V-belts are not properly tensioned, voltage is inadequate or speed is incorrect.
||Tension the belts correctly. Replace worn belts. Check the voltage. Use an appropriate power source.
|Cutting speed is too fast.
||Reduce the speed of advance.
|Blade is not perpendicular to the material being cut.
||Check the speed of the blade’s drive spindle and the flanges to ensure correct alignment of the blade and of the machine.
|Spindle is rotating too slowly.
||Check the speed of the drive spindle. If necessary, change the equipment or modify speed of rotation.
