Opening pressure:
Before starting, actuate tester several times with closed
manometer to rinse out the injector nozzle. To check, open
manometer, press lever until injector nozzle sprays. Read off value
from manometer. If the value that has been read off does not
correspond to the prescribed opening pressure of 13000 to 14300 kPa
(130 to 143 bar), readjust the injector nozzle using thrust
adjustment washers on the thrust spring.
Each thrust adjustment washer with a gradation of 0.05 mm
corresponds to a pressure difference of approx. 5 bar.
Replace thrust adjustment washers – see operation
"Injector Nozzle, Disassemble and Assemble".
