Metabo KFM 16-15 F Operating Instructions - Page 18

en ENGLISH Regularly check the indexable insert holder (18). Repair/replace damaged or worn holders for the indexable inserts. Regularly check all indexable inserts (19). Change damaged or worn indexable inserts. Turn/replace blunt indexable inserts or inserts where the coating is worn in due time. Blunt indexable inserts increase the risk that the machine will catch and breaks loose or that the indexable insert plate holder (18) is damaged. Do not use heavily worn or defective indexable insert plates. Always turn or replace all indexable inserts. Use only indexable inserts approved by Metabo. See the Accessories Section. A B contact surfaces and therefore may not be fastened sufficiently. Replace the strongly worn indexable inserts. 10. Cleaning Pull the mains plug out of the socket. Chips and particles can deposit at the milling head (18). This can lead to blockage of the milling head. Regularly clean the milling head and its surroundings and remove chips and particles. It is possible that particles deposit inside the power tool during operation. This impairs the cooling of the power tool. Conductive build-up can impair the protective insulation of the power tool and cause electrical hazards. The power tool should be cleaned regularly, often and thoroughly through all front and rear air vents using a vacuum cleaner. Prior to this operation, separate the power tool from the power source and wear protective goggles and a dust mask. 11. Troubleshooting Figure A: Normal wear: turn / replace indexable insert. Figure B: Wear after working on hard materials: turn / replace turning plate. In the event of heavier wear, do not use the indexable insert plate and instead replace. 1. Loosen the screws (12) and slide one chip protection plate (13) upwards. 2. Turn the indexable insert holder (18) manually if necessary. 3. Unscrew the fastening screw (20) and remove the indexable insert (19). 4. Clean indexable insert (19) and clamping surfaces on the indexable insert holder (18). 5. Turn the indexable insert or, if all blades are blunt, replace the indexable inserts. 6. Fix again the indexable insert (19) with a fastening screw (20). Torque: 3.5 Nm. 7. Slide the chip protection plate (13) all the way down. Tighten the screws (12). Note: Causes for indexable inserts with broken corners or, in extreme cases, for broken indexable inserts, can include: KFM 15-10 F, KFMPB 15-10 F: The electronic signal indicator (10) lights up and the load speed decreases. There is too much load on the machine! Run the machine in idling until the electronic signal indicator switches off. -The machine does not start. The electronic signal indicator (10) flashes (depending on the model). The restart protection is active. If the mains plug is inserted with the machine switched on or if the power supply is restored following an interruption, the machine does not start up. Switch the machine off and on again. KFM 16-15 F: - Restart protection: if the mains plug is inserted with the machine switched on or if the power supply is restored following an interruption, the machine does not start up. Switch the machine off and on again. - Overload protection: there is a reduction in load speed. The coil temperature is too high! Allow the machine to run at idle speed until it has cooled down. - Switching on the machine briefly reduces the voltage. Unfavourable mains power conditions may have a detrimental effect on other machines. Power impedances less than 0.4 ohm should not cause malfunctions. - Impacts on the indexable insert due to incorrect use: See chapter 8.2. - Workpiece vibrations: Fix workpiece without vibrations using clamping devices. - Indexable insert not correctly fastened: Always clean clamping surfaces and note torque. - Indexable insert not correctly fastened: Strongly 18 worn Indexable inserts do not have sufficient 12. Accessories Use only genuine Metabo accessories. Use only accessories that fulfil the requirements and specifications listed in these operating instructions.
