SAFETY INSTRUCTIONS Abrasive blades for different materials Blade type Concrete blade Metal blade Material Concrete, asphalt, stone masonry, cast iron, aluminium, copper, brass, cables, rubber, plastic, etc. Steel, steel alloys and other hard metals. Sharpening diamond blades 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. Dry cutting with diamond blade WARNING! Avoid using abrasive blades ! with water. The strength is impaired when abrasive blades are exposed to moisture. Diamond blades 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. 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. WARNING! Diamond blades get very hot ! when used. A heated blade can be deformed and cause damage to the machine as well as the user. 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. Wet cutting with diamond blade (K3000 Wet) Water cooling, which is used when cutting concrete, cools the blade and increases its service life while also reducing the formation of dust. WARNING! Diamond blades get very hot ! when used. A heated blade can be deformed and cause damage to the machine as well as the user. When wet cutting, the blade is continuously cooled to prevent overheating. There is an arrow on the machine that indicates the axleís direction of rotation that the blade is mounted on. Water connection with flow limiter (K3000 Wet) There is a flow limiter in the water connector that gives a constant flow, irrespective of the water pressure. The flow limiter may not be dismantled. Always use a sharp diamond blade. Material Diamond blades are ideal for masonry, reinforced concrete and other composite materials. 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. 12 - English Transport and storage • Do not store or transport the power cutter with the cutting blade fitted. All blades should be removed from the cutter after use and stored carefully. • Special care should be taken with abrasive blades. Abrasive blades must be stored on a flat, level surface. If an abrasive blades is stored in humid conditions, this can cause imbalance and result in injury. • Inspect new blades for transport or storage damage.
