8.3 Working Directions Grinding and sanding operations: Press down the machine evenly on the surface and move back and forth so that the surface of the workpiece does not become too hot. Rough grinding: position the machine at an angle of 30° - 40° for the best working results. Cutting-off operations: Always work against the run of the disc (see illustration). Otherwise there is the danger of the machine kicking back from the cut out of control. Guide the machine evenly at a speed suitable for the material being processed. Do not tilt, apply excessive force or sway from side to side. Wire brushing: Press down the machine evenly. 8.4 Rotate gear housing See illustration D on page 3. - Disconnect from the power supply. - Unscrew the fastening screw (a) of the lever (15). Remove the screw, lever (with its sheet metal part) and put aside. - Unscrew the 4 gear housing screws (b). CAUTION! Do not remove the gear housing! - Turn the gear housing to the desired position without removing it. - Screw in the 4 gear housing screws (b) in the available threads! Tightening torque = 3.0 Nm +/0.3 Nm. - Slide the spring that pushes the lever in position to the side and re-insert the lever (15) (with its sheet metal part), and fix with the fastening screw (a). Tightening torque = 5.0 Nm +/- 0.5 Nm. Check the lever for correct function: it has to be under spring tension. 9. Cleaning 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. 10. Troubleshooting Machines with VTC and TC electronics: The electronic signal display lights up and the load speed decreases (not W...RT). (7) There is too much load on the machine! Run the machine in idling until the electronics signal indicator switches off. The machine does not start. The electronic signal display (7) (depends on model) flashes. The restart protection is active. If the mains plug is inserted with the machine ENGLISH en 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. Accessories Use only genuine Metabo accessories. See page 6. Use only accessories which fulfil the requirements and specifications listed in these operating instructions. A Cutting guard clip / guard for cut-off grinding Designed for work with cutting disc and diamond cutting discs. Once the cutting guard clip is fitted, the safety guard becomes a cutting guard. B Extraction guard for cut-off grinding Designed for cutting through stone slabs with diamond cutting discs. With nozzle for extracting stone dust using a suitable extraction unit. C Extraction guard for surface grinding Intended for grinding of concrete, screed, wood and plastics with diamond cup wheels and/or fibre discs and suitable sanding plates. With nozzle for extracting stone, wood and plastic dust using a suitable extraction unit. Not suitable for extracting sparks or for grinding of metals. D Dust filter The fine mesh filter prevents coarse particles from entering the motor housing. Remove regularly and clean. E Hand protection Intended for work with backing pads, sanding plates, wire brushes and support plates, sanding pads, wire brushes and diamond Drill Bits for tiles. Install hand guard under the additional sidemounted handle. F Multiple position bar for side handle Permits numerous handle positions. G Bar side handle For a complete range of accessories, see www.metabo.com or the catalogue. 12. Repairs Repairs to electrical tools must be carried out by qualified electricians ONLY! If the connection lead is damaged, it must be replaced by a special connection lead. Contact your local Metabo representative if you have Metabo power tools requiring repairs. For addresses see www.metabo.com. You can download a list of spare parts from www.metabo.com. 13. Environmental Protection The generated grinding dust may contain harmful substances. Dispose appropriately. 21
