Grain flow sensor (if installed)
There are two important points to have a good
functionality of the grain flow sensor:
• The sensor plate must be clean
In some harvesting conditions it can happen that
material starts building up on the sensor plate. These
conditions can be recognised when other combine
elements (sieves, bubble-up auger, grain pan) start to
accumulate dirt. In case of serious material built up,
the readings of the sensor will become wrong.
Therefore it is advised to check daily. Clean sensor
plate 1 whenever other combine elements in the
combine needs to be cleaned for proper functioning.
To clean, proceed as follows:
1. Open the grain tank covers (if installed)
2. Remove the cover 1.
3. Open fast coupler 2 on top of the grain elevator
and swing the sensor open to the front of the
combine.
