I think that Tom is correct. The aircraft is a dual controlled aircraft with the throttle control to the four engines available to both pilots. The centre levers would appear to be the flap controls,one for each pilot. Note the fuel warning which could have adverse effects on engine performance and aircraft safety if the incorrect fuel was used.It looks as if the fuel specifiied may be AVGAS 100/130. Get AVGAS confused with AVTUR and it could lead to the loss of the aircraft and loss of life.Remember an ex RAF Varsity which was fuelled up with AVTUR instead of AVGAS,as a visiting aircraft and which led to loss of life and the complete loss of the aircraft immediately on take off.
