Speed Transducer for the Pump

The speed transducer that measures rotations per minute (RPM), is
located at the inner side of the PTO shield.
The sensor is an inductive type, which requires metallic protrusions to
pass by it to trigger a signal.
If the sensor is exchanged, it must installed accurately to function
properly.
Adjustment
1. Adjust the air gap (A) between sensor tip and the protruding
pump part by turning the counter nuts at the support bracket for
the sensor.
The air gap (A) must be set to 1 mm (+0.3/-0.0 mm).
Use a feeler gauge or similar tool to verify.
2. Verify transducer function on the controller:
