7. To finish work: Remove the tool from the workpiece, switch off machine. Let motor come to a stop, put down machine. 9. Maintenance 9.1 Change indexable inserts Regularly check the holder for the indexable inserts (22). Repair/replace damaged or worn holders for the indexable inserts. Regularly check all indexable inserts (20). Change damaged or worn indexable inserts. Remove the battery pack from the machine / pull the plug out of the socket before making any adjustments, changing tools, carrying out maintenance or cleaning. Indexable inserts, holders for indexable inserts, workpiece and chips can be hot after work. Wear protective gloves. Turn/replace blunt indexable inserts or inserts where the coating is worn in due time. Blunt indexable inserts increase the risk of the machine getting jammed and climb out. Always turn or replace all indexable inserts. Use only indexable inserts approved by Metabo. See the Accessories Section. 1. By turning the adjustment ring (13) to the stop, unscrew the holder for the indexable inserts (22) as much as possible - this provides good access to the indexable inserts. 2. Press in the spindle locking button (2) and turn the holder for the indexable inserts (13) by hand until the spindle locking button (2) engages. Keep the spindle locking button (2) pressed. 3. Unscrew the fastening screw (21) and remove the indexable insert (20). 4. Turn the indexable insert or, if all blades are blunt, replace the indexable inserts. 5. Fix again the indexable inserts (20) with a fastening screw (21). Torque: 5 Nm. 6. Turn the adjusting ring (13) in the opposite direction, so that the holder for the indexable inserts (22) is again in its normal work range. (So that the maximum permitted chamfer height is not exceeded, see chapter Technical Specifications). 9.2 Replace ball bearing stationary seal ring (only if required): Regularly check the ball bearing stationary seal ring (19) for smooth running. Replace defective ball bearing stationary seal ring. (order no.: 316093300) 1. Remove screw (18) and remove ball bearing stationary seal ring. 2. Put new ball bearing stationary seal ring (19) in place and add screw (18), tighten firmly. ENGLISH en 9.3 Adjust scale (only if required): The graduated ring (12) comes properly set from the factory. If indexable inserts are to be used for radii or if the settings should have been misaligned, the scale has to be adjusted as follows: 1. Lift the adjustment ring (13) and turn in such a way that the indexable insert (20) does not remove any material. (chamfer height = 0 mm) 2. Loosen the two clamping screws (12). 3. Turn the graduated ring (12) until the chamfer height 0 mm is shown. 4. Tighten the two clamping screws (12). 5. Carry out trial cut. 10. Cleaning Chips and particles can deposit at the cutter head. This can lead to blockage of the cutter head. Regularly clean the cutter 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 or by blowing in dry air. Prior to this operation, separate the power tool from the power source and wear protective glasses and dust mask. 11. Troubleshooting 11.1 Mains powered machines: - Overload protection: There is a MAJOR reduction in load speed. The motor temperature is too high! Allow the machine to run at idle speed until it has cooled down. - Overload protection: There is a MINOR reduction in load speed. The machine is overloaded. Reduce the load before continuing to work. - Metabo S-automatic safety shut-down: The machine has SHUT DOWN by itself. If the slew rate of the current is too high (for example, if the machine suddenly seizes or kickback occurs), the machine switches off. Switch off the machine using the slide switch (4). Switch it on again and continue to work as normal. Try to prevent the machine from seizing. See chapter 4.1. - Restart protection: The machine does not start. 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. 11.2 Cordless machines: - The electronic signal display (7) lights up and the load speed decreases. The temperature is too high! Run the machine in idling until the electronics signal indicator switches off. 15
