Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
Thank´s for your help, I already recived these manual from you

COOKING EQUIPMENT
Do not leave the fat or oil on the frying pan on the hob to store it, in case the hob is inadvertantly switched on. 1. Preparing the food Seal the food by coating with flour, egg and breadcrumbs or batter. Do not use a basket with batter coated food as they will stick. 2. Amount of oil For safety purposes, fill the pan only one-third full of fat or oil. 3. Testing the temperature of the oil It is advisable to test the temperature of the oil with a thermometer. Alternatively drop a small cube of bread into the oil which should brown in just under a minute if the oil is at 190° C/375°F. 4. Cooking the food Lower the food gently into the oil. Do not add too much food at once or the temperature of the oil will be reduced and may result in soggy, greasy food. Turn the food if necessary: doughnuts float to the surface so will not brown on the upperside if not turned. Once cooked, drain on absorbent paper, kitchen roll for example. 5. Double frying of chips Double frying will ensure good chips. First fry the chips for a few minutes at 170°C/340°F to seal the outside. Remove the chips from the oil. Increase the temperature of the oil to 190°C/375°F to finish cooking and brown the chips. Chips may be kept for several hours after the frying before finishing off with the second frying.
