Ground fault circuit interrupter (K3000 Wet) Ground fault circuit interrupters are for protection in case an electrical fault should occur. The LED indicates that the ground fault circuit interrupter is on and that the machine can be switched on. If the LED is not on, push the RESET button (green). Check the ground fault circuit interrupter •Connect the machine to the socket. Push the RESET button (green) and the red LED lights up. •Start the machine. •Push the TEST button (blue). •The ground fault circuit interrupter should trip and the machine switch off instantly. If not, contact your dealer. •Reset with the RESET button (green). 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 purpose than that it was intended for. General •Cutting blades are available in two basic designs; abrasive discs 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 Cutting blades K3000 K3000 Wet Abrasive discs Yes Yes* Diamond blades Yes Yes Rescue blade No No *Without water Cutting blades for different materials Concrete Metal Plastic Abrasive discs X X X Diamond blades X Hand-held, high-speed machines Our cutting blades are manufactured for high-speed, portable power cutters. If blades from other manufacturers are used, ensure that the blades conform to all regulations and demands that concern this type of power cutter. 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 discs The cutting material on abrasive discs 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. 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. Abrasive discs for different materials Disc type Material Concrete disc Concrete, asphalt, stone masonry, cast iron, aluminium, copper, brass, cables, rubber, plastic, etc. Metal disc Steel, steel alloys and other hard metals. WARNING! Avoid using abrasive discs with water. The strength is impaired when abrasive discs 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 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. There is an arrow on the rear of the machine that indicates the axles direction of rotation that the disc is mounted on. Always use a sharp diamond blade. Material Diamond blades are ideal for masonry, reinforced concrete and other composite materials. Diamond blades are not recommended for cutting metal. 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. 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 br...
