*Plastic reducing bushes may only be used with abrasive discs. Do not use reducing bushes with diamond blades or tungsten carbide blades.We recommend that the spindle is replaced so that it fits the blades to be used rather than using a reducing bush. Contact your service workshop for details.
Guard
Check that the guard is not cracked or shows signs of any other damage. Clean the inside of the guard before fitting a new blade. Check that the guard can be adjusted.
Diamond blades
Diamond blades consist of a steel body with segments that contain industrial diamonds

!WARNING!
Cool diamond blades continuously with water to prevent overheating that can cause the blade to break and pieces being thrown off resulting in injury and damage.
Using diamond blades
Proceed as follows:
•Let the cutting blade rotate in the same direction as the arrow markings indicate.
•Cool continually with water.
•Keep the cutting blade sharp.
•Remove the cutting blade when the machine is transported.
Avoid:
•Running the cutting blade in the wrong direction.
•Forcing a dull blade or wedging the blade into a cut.
•Transporting the power cutter with the blade fitted.
•Letting the blade fall on the work piece.
Diamond blades for dry cutting
Diamond blades for dry cutting are a new generation of blades that do not require water cooling. However, the blades are still damaged by excessive heat. It is good economics to let the blade cool by simply lifting the blade from the cut every
