WARNING! Do not use abrasive blades with ! water. The strength is impaired when abrasive blades are exposed to water or moisture, which results in an increased risk of the blade breaking. Diamond blades General WARNING! Cutting plastics with a diamond ! blade can cause kickback when the material melts due to the heat produced when cutting and sticks to the blade. WARNING! Diamond blades get very hot ! when used. An overheated blade is a result of improper use, and may cause deformation of the blade, resulting in damage and injuries. • Diamond blades consist of a steel core 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. Sharpening diamond blades • Always use a sharp diamond blade. • Diamond blades can become dull when the wrong feeding pressure is used or when cutting certain materials such as heavily reinforced concrete. Working with a blunt diamond blade causes overheating, which can result in the diamond segments coming loose. • Sharpen the blade by cutting in a soft material such as sandstone or brick. Diamond blades for dry cutting • Diamond blades for dry cutting can be used both with and without water cooling. • When dry cutting, lift the blade out from the cut every 30- 60 seconds and let it rotate in the air for 10 seconds to let it cool. If this is not done, the blade may be overheated. Diamond blades for wet cutting • Diamond blades for wet cutting must be water cooled. If this is not done, the blade may be overheated. • Water cooling cools the blade and increases its service life while also reducing the formation of dust. Toothed blades, carbide tipped blades and emergency situations Carbide tipped specialty blades are intended only for use in rescue missions and only by trained staff.
