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.

When the hob has been fully installed it will be necessary to check the minimum flame setting. To do this, follow the procedure below. Turn the gas tap to the MAX position and ignite. Set the gas tap to the MIN flame position then turn the control knob from MIN to MAX several times. If the flame is unstable or is extinguished follow the procedure below.
Re-ignite the burner and set to MIN. Remove the control knob. To adjust, use a thin bladed screwdriver and turn the adjustment screw (see diagram) until the flame is steady and does not extinguish, when the knob is turned from MIN to MAX. Repeat this procedure for all burners.
Minimum adjustment screw
Remove left hand pan support and front left burner cap and crown.
Fit manometer tube over the injector. Turn on the burner gas supply and ignite another burner. The pressure reading should be nominally 20mbar and must be between 17 mbar and 25mbar. Turn off the burner supplies.
