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.

MAINTENANCE AND CLEANING
Before carrying out any maintenance or cleaning isolate the cooker hood from the mains supply. The cooker hood must be kept clean, as a build up of grease or fat can be a fire hazard.
External Cleaning
Wipe the cooker hood frequently with warm soapy water using a mild detergent.
Always wear protective gloves when cleaning the hood. Never use scouring pads or abrasive cleaners. Never use excessive amounts of water when cleaning particularly around the control panel.
Charcoal Filter
The charcoal filter cannot be cleaned, it should be replaced approximately every three months or more often if the hood is used for more than three hours per day. (See installing the cooker hood for instructions on how to remove the charcoal filter).
K To Remove/Replace the Charcoal Filter
1. Remove the thumb screw through the centre of the charcoal filter, from the motor support. The charcoal filter can now be removed.
