Anyone know how to correct translate it into English?

53 Schalthebel Feuerlöschanlage (links und rechts) ein -aus
54 Abstimmungs Hebel für die Drehzahl (gross-klein-Sturzflug)
55 Tankschalthebel (Brandhan) (auf -zu)

from DE ?

53 Schalthebel Feuerlöschanlage (links und rechts) ein -aus:
shift lever fire-extinguisher (left and right) on - off

54 Abstimmungs Hebel für die Drehzahl (gross-klein-Sturzflug):
control lever R.p.m. coordination (high - low - dive)

55 Tankschalthebel (Brandhan) (auf -zu):
engine fuel shut off valve (open - close)

hope these are the correct terms

More simply:

53 Fire Extinguisher (left / right engine): on - off
54 RPM Switch: high - low - dive
55 Fuel Switch (in case of fire): open - closed

edit: 53 and 55 are mostly used together in case of engine fire: first you cut off the fuel (55) and wait until the engine stops, then you use 53 to extinguish the engine fire
