Carefully turn the pump coupling against the direction of
rotation until both light emitting diodes on the instrument
light up. The injection pump is now in position for the in-
jection cycle to commence on No.1 cylinder.
Note: The measuring instrument is very sensitive, which en-
sures that the setting will be exact.
Make sure that the pump coupling is not turned too far, but
precisely to the point where both the light emitting diodes
light up. If the pump coupling is turned to far, the setting pro-
cedure must be carried out again.
