Metabo MFE 40 Operating Instructions - Page 15

which a groove is to be cut, and slowly guide down until the set cutting depth has been reached. Then push the machine in cutting direction Always push the machine in the stipulated direction through the material to be processed! See arrow (11) on the guard. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece. ENGLISH en 10. Troubleshooting The machine does not start. The electronic signal indicator (5) flashes. 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 back on again. 11. Accessories Once the groove is complete, switch off the tool and hold it steady until the diamond cut-off wheel comes to a stop. Never attempt to remove the cutting disc from the cut while the wheel is in motion otherwise kickback may occur. Remove the machine from the cut. Put the machine down on its side. You can remove the remaining strip between the two chases with the chase extraction chisel provided. Grooves of greater depth cannot be cut into hard material (e.g. cement) in one movement. Use only genuine Metabo accessories. Use only accessories that fulfil the requirements and specifications listed in these operating instructions. Metabo diamond cut-off wheels: Ø 125 mm , laser-welded, suitable for dry cutting, bore = 22.2 mm, for wall chaser MFE 40 Area of use Order number for hard and medium-hard materials (e.g. concrete, including reinforced concrete) 6.24541 8. Maintenance, Cleaning Significantly reduced work progress and increased feed force are signs for blunt diamond cut-off wheels. Sharpen blunt diamond cut-off wheels by carrying out short cuts into abrasive materials such as sand-lime brick. It is possible that particles deposit inside the power tool during operation. This impairs the cooling of the power tool. for abrasive materials (e.g. abrasive cement, sandstone, sand-lime brick, aerated concrete and similar) 6.24641 Metabo cutting wheels: Diamond cutting wheel Dia FS2 UP 6.28298 Diamond cutting wheel Dia FS3 UP 6.28299 See www.metabo.com or the catalogue for a complete range of accessories. 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. 12. Repairs Repairs to power tools must only be carried out by qualified electricians! 9. Overload protection 9.1 Safety clutch There is an automatic safety coupling built-in to the gears of the wall chaser. This protects the operator from the high torque that may, for example, occur if the diamond cut-off wheel is canted during work. The safety coupling protects and at the same time takes the strain off the motor and the gears of the machine. When the safety coupling engages, immediately switch the motor off (do not allow the coupling to drag!), 9.2 Electronic overload indicator The electronic signal indicator (5) is on Load of the machine is too high! Reduce the feed pressure until the electronic signal indicator goes off. A defective mains cable must be replaced only with a special, original mains cable from Metabo available from the Metabo service. Contact your local Metabo representative if you have Metabo power tools requiring repairs. See www.metabo.com for addresses. You can download a list of spare parts from www.metabo.com. 13. Environmental Protection The generated grinding dust may contain harmful substances. Do not dispose with household trash; dispose of properly at a collection point for hazardous waste. Observe the national regulations on environmentally compatible disposal and on the recycling of disused tools, packaging and accessories. Only for EU countries: never dispose of power tools in your household waste! 15
