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

Important to know
If the hood is run at the same time as a burner or fireplace that depend on ambient air (for example gas, Diesel, coal or wood heaters, water heaters, etc.) be careful, because the hood, when it exhausts the air, removes the ambient air required by the burner or fireplace for combustion. Not valid if the cooker hood is used in recirculation mode.
Maintenance
Before performing any maintenance operation, disconnect the hood from the electricity.
Grease filter
This serves to hold the grease particles in suspension. The metal filter should be washed every month with warm soapy water or, if possible, in the dishwasher (60°C). To remove: q Open the grid (A - fig. 7). q Remove the stops (fig. 11). Leave to dry before refitting it. Clean the grid too as well as the grease filter.
Fig. 11
Carbon filter
This filter dissolves cooking odours. It should be changed every 4-5 months in normal use. The carbon filter must never be washed. In order to remove it turn the filter anti-clockwise until it becomes unhooked from its seat. (Fig. 9).
Attention
Failure to observe the rules for cleaning the appliance and changing and cleaning the filters may cause fires. Therefore, we recommend observing these instructions.
Cleaning
To clean the outside of the hood use a cloth moistened with denatured alcohol or neutral liquid detergents. Never use products containing abrasives.
Changing the lighting elements
q Disconnect the hood from the electricity. q Open the grid (Fig. 7). q Replace the damaged part with one of equal rating. 7
