SAFETY INSTRUCTIONS
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
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 30–60 seconds and letting it rotate in the air for 10 
seconds.
!
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.
