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 you for your manual It has the basic things to and i use the Oszi for Longer Time.

CHECKING LID SHUT-OFF DEVICE
1. Lift the lid 2. Turn one hotplate tap to its full on position and push the ignition button. 3. Close the lid. There should now be no gas supply to the hotplate and the burner will go out. 4. Turn off the hotplate and lift the lid. The gas supply should now be restored to the hotplate, when the tap is turned on.
CHECKING THE SECOND OVEN
1. Turn the second oven thermostat control knob anticlockwise to Mk.8 and press the ignition button. As soon as the burner is alight the button can be released. 2. When the oven burner lights up there should be a low gas rate at first to the oven burner which is the F.S.D. by-pass rate. 3. When the F.S.D. phial has heated up it opens the F.S.D. valve and the main gas stream flows to the burner. 4. After 1 minute check that the flame covers the full width of the burner and is stable. 5. Set the oven control to Mk. 2, close the oven door and check that after about 10 minutes the flame size has reduced. 6. Turn off the control knob and check that the oven flames go out.
