User manual KRESS FM 6990 E

[. . . ] A uniform and not too excessive feed will extend life of cutter, will prevent burns on wood and protect motor against overloads. Pull mains plug as a protection against unauthorized operation whenever the work is interrupted for extended periods. Clamp the milling motor on the clamping collar with a round-type flange around the entire circumference (Eurohals ­ Euro-collar). For more demanding applications, the tool must be secured at the spindle and ternsion nut with two 14/22 size wrenches. [. . . ] 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. 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. Motor, cleaning and care The powerful universal motor has adequate power reserves. The vent holes should always be kept unobstructed and clean since uniform ventilation is extremely important. Carbide-tipped cutters require special, careful treatment since the cutting edges are easily subject to chipping. To eliminate any risk of injuries, the use of damaged cutting, grinding and polishing tools on our high-speed cutting and grinding motor is no longer permitted. Free-hand work The milling and grinding motor is ideally suited to many kinds of free-hand work due to its small size and light weight. Switch off motor immediately at end of work as a safety measure against injuries! [. . . ] This electrical tool has been designed with high precision and was approved after undergoing strict quality control checks in the factory. We are therefore able to guarantee free servicing of any production or material faults which arise in the 24 months after the date of sale to the purchaser. We reserve the right to repair defective parts or else replace them with new parts. The guarantee will be rendered void if the device is used improperly, mistreated or opened up by unauthorised repair personnel. [. . . ]
