Special blades
Some cutting blades are designed for stationary equipment and for use with attachments.Such cutting blades must not be used on portable power cutters.
Always contact local authorities and make sure you are following applicable directives.
Abrasive discs
The cutting material on abrasive discs consists of grit bonded using an organic binder. ”Reinforced blades” are made up of a fabric or fibre base that prevents total breakage at maximum working speed if the blade should be cracked or damaged.
A cutting blade’s performance is determined by the type and size of abrasive corn, and the type and hardness of the bonding agent.

Check that the blade is approved for the same or higher speed according to the aproval plate of the engine. Never use a cutting blade with a lower speed rating than that of the power cutter.
Ensure the blade it not cracked or damaged in any other way.
Test the abrasive disc by hanging it on your finger and tapping it lightly with a screwdriver or the like. If the disc does not produce a resonant, ringing sound it is damaged.
Diamond blades
Diamond blades consist of a steel body provided with segments that contain industrial diamonds.
Diamond blades ensure lower costs per cutting operation, fewer blade changes and a constant cutting depth.
When using diamond blades make sure that it rotates in the direction indicated by the arrow on the blade.
Always use a sharp diamond blade. Sharpen the blade by cutting in a soft material such as sandstone or brick.
Diamond blades are available in several hardness classes. A "soft" diamond blade has a relatively short service life and large cutting capacity. It is used for hard materials such as granite and hard concrete. A "hard" diamond blade has a longer service life and reduced cutting capacity, and should be used for soft materials such as brick and asphalt.
Material
Diamond blades are ideal for masonry, reinforced concrete and other composite materials. Diamond blades are not recommended for cutting metal.
Diamond blades for wet cutting
WARNING! Cool diamond blades for wet
!cutting continuously with water to prevent overheating, which can cause the blade to break up and eject pieces that can cause injury.
Diamond blades for wet cutting should have water poured over them during the cutting to cool the blade and bond the dust.
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 will still be damaged by excessive heat. It is most economical to allow the blade to cool by simply lifting it out from the cut every
