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.

Do not mix up the cutters and combs as the shaving performance may be adversely affected for several weeks before optimal shaving performance is restored.

Do not clean more than one cutter and comb at a time, since they are all matching sets. If you accidentally interchange the cutters and combs, it could take several weeks before optimal shaving performance is restored.

Replace the set back into the Razor Head Assembly so that the �wings� on the comb fit within the brackets located towards the center of the Assembly.
