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.

Changing dustbag
Change dustbag S when display F is filled with colour (can be checked with the appliance operating at maximum suction and with the nozzle raised from the floor). A change may be necessary even if the bag does not appear to be full. Fine dust can block the pores and reduce the suction power of the appliance. Switch off the appliance and open the dust chamber lid by pulling release catch G. Remove dustbag S by pulling on the sealing tab. Push new dustbag into the retainer until it clicks into place. Take care when closing the dust chamber lid that the dustbag is completely inside the dustchamber border. The dust chamber lid will not close unless a dustbag has been inserted. Please do not use force!
