To do this, hold a collecting basin beneath the water container. Pull out the rubber stopper (black arrow in Fig. 5) on the bottom of the water container and drain the water. Once the water has run out, put the rubber stopper back in the discharge opening. Fig.6). Note: It may be necessary to remove the screws completely in order to remove the water container. Pull the container out from below. The dry/wet grinding machine can be used for coarse or fine grinding. Please make sure that this machine is not in permanent operation. To prevent possible overloading/overheating it should not be operated for more than 15 - 30 minutes at a time. Let grinder cool down before restarting. Apply moderate pressure when holding the workpiece against the grinding wheel. Remember that the metal heats up by the grinding. The workpiece should therefore regularly cooled by submerging it in cold water. The dry grinding wheels of this bench grinders are suitable for rough grinding only. Size of part to be machined The part to be machined must at least be large enough to hold securely in both hands. A larger work piece must also be able to be held securely in place and must not slip from the work piece support during the grinding process. When selecting the size of the work pieces, please bear in mind the grinding capacity of your grinding machine. Drill grinding The work piece supporting mechanism on the right grinding wheel is fitted with a trough for grinding borers. After switching on the grinding machine, hold the borer to be sharpened with both hands and press it into the trough. Then carefully guide the tip of the borer on to the grinding wheel and slowly turn the borer during the entire grinding process. Wet grinding Prior to wet grinding check that there is enough water in the water container (one third of the wet grinding wheel must be immersed in water!). If necessary top up the water in the water container. Switch on the grinding machine and stand to the left of the grinding machine in front of the wet grinding wheel. Hold the work piece with both hands and carefully lower it on to the wet grinding wheel. You can also support the work piece on the teeth of the water holder and lower it on to the grinding wheel. Prior to Commissioning The mains voltage must correspond with the voltage stated on the machine's name plate. - The grinding wheels are to be subjected to a resonance test (see section Grinding Wheel Check below). This resonance test is also to be carried out when replacement - grinding wheels are mounted. The grinder is to be subjected to a no-load trial run for at least 5 minutes. Do not stand in the grinder’s danger zone during this trial run. Grinding Wheels When replacing grinding wheels it is important to ensure that the new wheel fits your grinding machine, i.e. arbor bore size, outer diameter and wheel width must correspond with the original grinding wheel. This information is shown on all commercially available grinding wheels. It is recommended to check if an approval code is shown on the grinding wheel and to buy only approved grinding wheels. Genuine Elektra Beckum grinding wheels are guaranteed for a constant high quality level. They are available at your Elektra Beckum dealer in all common sizes and compositions. 10 1 Manufacturer’s address or stamp 2 Pe...
