[. . . ] Never tighten clamp nut when no tool is inserted. Collet chuck might be compressed excessively and suffer damage. Before mounting tools, disconnect the machine from the power supply, or remove the mains cable module (17) from the casing using the locking device button (18). Pull mains plug prior to working on motor. [. . . ] Machines with double insulation always carry the international symbol. The machines are interference-suppressed in accordance with EN 55014. Always select feeding direction of work against direction of rotation of cutter (up-cutting): The motor starts up slowly until reaching the preset speed, thus protecting the user and prolonging the life of the machine. Electronic overload protection The speed of the milling motor is reduced by the integrated motor monitoring should the load become too high for the motor. The load on the machine must be reduced. Ideally, the machine should be removed from the work piece briefly so that full capacity is regained. Electronic control with tachogenerator The full-wave control electronics makes possible a large control range of 8000 - 26 000 rpm-1. By using the full-wave control electronics' adjustment dial (16), the optimal cutting speed or working rotational speed can be adjusted regardless of: - material (hard woods, soft woods or plastics) - milling or grinding tool (small diameter, lower or higher quality). - The required cutting or working rotational speed depends on many factors (varying degrees of hardness of the material being machined, milling quality, infeed, etc. The optimal adjustment must be determined by trial and error when beginning work. Very high speeds mean rapid wear and a short working life for your tools!When using other cutting tools the speeds per minute which have been durably marked by the manufacturer on the turning tools must not be exceeded!Replacing carbon brushes Our service personnel will do this and all other servicing work quickly and professionally. This has been made very straightforward by the new mains cable module (17). Press both locking keys (18) and pull the mains cable module (17) out of the handle. Insert the new mains cable into the handle and lock in place. Different lengthed mains cables are available as special accessories. Only use the mains cable module for KRESS power tools!Do not attempt to operate other electrical appliances with it!Motor, cleaning and care The powerful universal motor has adequate power reserves. For a long life, be sure to blow dust out of housing after each job. The vent holes should always be kept unobstructed and clean since uniform ventilation is extremely important. [. . . ] Parts which have been replaced become our property. The guarantee will be rendered void if the device is used improperly, mistreated or opened up by unauthorised repair personnel. Parts which are subject to wear are not covered by the guarantee. The guarantee may only be enforced when defects are reported without undue delay (including shipping damage). [. . . ]
