-Connect the line of the nozzle tester to the 1 cylinder of the injection pump Build up a pressure of max. 20-30 bar and slowly turn the pump in the direction of rotation (arrow) until a high resistance can be felt.
Caution: Some versions have a pressure valve built into the line fitting, which must be removed for the check.
The edge of the circlip can be checked in this position with the corresponding letter on the rotor and adjusted if necessary.
Start of injection = letter W or X must correspond exactly with the ground edge of the circlip.
