Resumen del manual
This angle grinder is designed as a dry grinder/cutter. Failure to observe this warning could result in a fatal shock. Holding and guiding the tool 1. Always clamp the workpiece. 2. Do not overload the tool so that the disc slows down. Let the tool do the work rather than applying pressure. The weight of the tool alone provides sufficient pressure. 3. Cutting and grinding discs become very hot when in use. Take care not to touch them until they have cooled down. 4. Hold the tool securely and make sure that you have full control at all times. 5. During a cutting operation, maintain an angle of 30° to 40° between the tool and the workpiece. 6. During grinding, maintain an angle of 20° to 30° between the tool and the workpiece. Replacing a disc CAUTION. Switch off the grinder and disconnect it from the power point. Depressed Disc 1. To remove the disc, press and hold the spindle lock button (2) (Fig. H) and rotate the disc by hand until the H I 9 spindle lock engages and locks the spindle. Use the pin wrench (11) to unscrew the outer flange (13). Note that this flange unscrews anticlockwise. (Fig. I) 2. Remove the outer flange (13) (Fig. J) and the used J K disc.(Fig. K) 3. Clean the flanges (13 and 15) and check the new disc. 4. Ensure that the non-threaded inner flange (15) is on the spindle and located correctly. The two machined flat sections on the inner flange (15) must face the angle grinder and locate in the matching positions on the spindle. (Fig. L) L Fit the new disc, ensuring that the disc is correctly located on the inner flange. NOTE. Make sure that you select the correct disc for the planned application, i.e. fit a metal grinding disc for cutting metal, a masonry grinding disc for grinding masonry, a cutting disc for cutting, etc. 5. Fit the outer flange (13) with the raised centre section facing outwards as NM shown in the picture below. (Figs. M and N) IMPORTANT. The depressed centre disc must be correctly located on the inner flange. Refer to the assembly drawing below. 6. Turn the new disc by hand, ensuring that it is tight in the flanges and that it rotates fully and does not wobble unduly. 7. Run the angle grinder no load for at least one minute to ensure the new disc is in good condition. Make sure you are wearing all the safety gear and that you face the grinder away from you. Flat Disc 1. To remove the disc, press and hold the spindle lock button (2) and rotate the disc by hand until the spindle lock engages and locks the spindle. Use the pin wrench (11) to unscrew the outer flange (13). Note that this flange unscrews anticlockwise. 2. Remove the outer flange (13) and the used disc. 3. Clean the flanges (13 and 15) and check the new disc. 4. Ensure that the non-threaded inner flange (15) is on the spindle and located correctly. The two machined flat sections on the inner flange (15) must face the angle grinder and locate in the matching positions on the spindle. Fit the new disc, ensuring that the disc is correctly located on the inner flange. NOTE. Make sure that you select the correct disc for the planned application, i.e. fit a metal grinding disc for cutting metal, a masonry grinding disc for grinding masonry, a cutting disc for cutting, etc. 10 5. Fit the large outer flange (14) and ensure that the raised O P portion is pressing against the disc. (Fig. O) Then fit the outer flange (13) making sure that the raised centre section is pointing towards the disc. (Fig. P) IMPORTANT. The raised centre portion of the flange nut MUST BE correctly positioned as it locates the grinder/ cutting wheel. Refer to the assembly drawing below. 6. Turn the new disc by hand, ensuring that it is tight in the flanges and that it rotates fully and does not wobble unduly. 7. Run the angle grinder no load for at least one minute to ensure the new disc is in good condition. Make sure you are wearing all the safety gear and that you face the grinder away from you. Disc Selection Grinding Discs – 230mm x 22.2mm bore x 6mm. Generally used on steel and high grade steel, also available for stone, concrete and aerated concrete. Cutting Discs – 230mm x 22.2mm bore x 3mm. Generally used on steel, high grade steel and stainless steel also available for stone, concrete and aerated concrete. Diamond Blade Disc – 230mm x 22.2mm bore x 2.2mm. These types of discs are generally used in masonry cutting applications. The are suited for cutting concrete, tiles, marble, granite and sand stone. LED brush-wear indicator The LED Brush-wear indicator (16) provides early warning that the carbon brushes within the tool require replacement. When the carbon brushes are worn down, it will result in a current drop creating inefficient motor power which can result in costly repair. The LED Brush-wear indicator warns the user when a green light appears on the LED display. The carbon brushes must be replaced soon. When the carbon brushes are replaced, the next time the tool is used the green light will not appear. (Fig. Q) Q CAUTION. The...
