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

NOTE: Make sure oven is cool before replacing a light bulb.
To replace an oven light:
1. Disconnect power and make sure the oven is cool before replacing the light bulb.
4. Replace the light bulb cover by turning it clockwise. The light bulb cover must be in place when using the oven. The cover protects the bulb from breaking and from high oven temperatures. 5. Reconnect power. NOTE: The oven lights will not work during the Self-Cleaning cycle.
2. Remove the glass bulb cover in the back of the oven by turning it counterclockwise. 3. Remove the light bulb from its socket. Replace the bulb with a similar 125-volt, 15-watt appliance bulb.
