| The blade is too hard for the material being cut (e.g. a blade for a block or a universal blade used for a prolonged period on hard brick; a blade for asphalt used to cut reinforced concrete). | See the blade selection table or consult your distributor or the manufacturer who will indicate the proper blade for the material to be cut. |
| The output power is inadequate to allow the blade to cut correctly (belts too slack, voltage and motor output insufficient). | Check the belts, the voltage and the motor output power. |
| The blade segments still appear to have some life left but the blade is not cutting. | Cut an abrasive material until the diamonds surface again. This remedy may prove necessary from time to time; however, if the blade becomes dull too often, this probably means it is too hard for the material being cut. |
| The blade segments still appear to have some life left but the blade is not cutting. | The segments of a blade with a harder bond provided for abrasive materials require a non-diamond support at the base of the diamond segment in order to achieve better adherence to the steel plate. Wearing of the blade to this state is considered normal wear. The blade must therefore be replaced. |
| The tool becomes smooth because of excessive speed of rotation. | Match the specification and the diameter of the blade to the machine. |
| The tool becomes smooth due to excessive pressure of the blade on the material to be cut. | Ensure that the pressure of the blade on the material allows natural sharpening of the blade without any excess. |
