SAFETY INSTRUCTIONS Cutting blades WARNING! A cutting blade may burst ! and cause injury to the operator. Never use a cutting blade at a lower speed rating than that of the power cutter. Never use a cutting blade for any other materials than that it was intended for. General • Cutting blades are available in two basic designs; abrasive baldes and diamond blades. • High-quality blades are often most economical. Lower quality blades often have inferior cutting capacity and a shorter service life, which results in a higher cost in relation to the quantity of material that is cut. • Make sure that the right bushing is used for the cutting blade to be fitted on the machine. See the instructions under the heading Assembling the cutting blade. Suitable cutting blades 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. Blade vibration The blade can become out-of-round and vibrate if an excessive feed pressure is used. A lower feed pressure can stop the vibration. Otherwise replace the blade. The blade must be of the recommended type for the material to be cut. Abrasive blades 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. 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.
