3.3 Reverse
1) Turn the rotary knob to 15% fuel injection quantity (see display).
2) Push the button START AHEAD or START ASTERN until the engine runs in the
applicable direction.
Note: On ships under way, this procedure can be some minutes, because the
propeller is dragged in the opposite sense of rotation.
3.4 Engine Stop
1) Use the rotary knob to decrease the engine speed / load.
2) Push the STOP button.
Note: The buttons and rotary knob only operate when the related WECS−9520
control panel is selected to be in control (see 4618−1 WECS−9520 manual
control panel). You can also use the ECR manual control panel for the
procedure above.

CAUTION
Equipment Hazard: Leaks that are found during the engine
control system checks must be repaired.
