CUTTING BLADES
Abrasive blades | ||
! | 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. | |
•The cutting material on abrasive blades 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.
•Ensure the cutting blade is not cracked or damaged.
•Test the abrasive blade by hanging it on your finger and tapping it lightly with a screwdriver or the like. If the blade does not produce a resonant, ringing sound it is damaged.

Diamond blades
General
WARNING! Never use a diamond blade to
! cut plastic material. The heat produced during cutting may melt the plastic and it can stick to the cutting blade and cause a kickback.
Diamond blades become 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.
Cutting metal generates sparks that may cause fire. Do not use the machine near ignitable substances or gases.
• 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.
Diamond blades for different materials
•Diamond blades are ideal for masonry, reinforced concrete and other composite materials.
•Diamond blades are available in several hardness classes.
•Special blades should be used when cutting metal. Ask your dealer for help in choosing the right product.
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.
