Honda Accord SJ542BP Sedan 4 doors 1980

Estimated:
I have acquired in today a Honda Accord SJ542BP Model 1980 and I urgently need the mechanics manual to repair it.
The vehicle is quite well of mechanics but very neglected.
I need to disarm it, check it, clean it and put it ready. I got one that said Honda Accord 1980 supplement but it is for an automatic vehicle but this is not automatic and does not have the engine explodes.
If they could help me with this issue, I would be very grateful.
