operation is performed by annunciator 2.
The switch 3 has three fixed positions:
"FDA off" – middle position;
"FDA automatic control" – upper position;
"FDA positive activation" – lower position.
The mode "FDA off" is used when moving on roads with hard surface when the traveling
speed is above 13 km/h in order to avoid increased wear of front wheel tires.
In the position "FDA automatic control" the FDA drive is automatically engaged
when the rear wheel skidding limit is exceeded. The FDA drive is disengaged automatical-
ly as the rear wheel skidding drops below the limit.
Annunciator 2 is on, when the FDA drive is engaged, and it goes out when the FDA drive
is disengaged.
The mode "FDA automatic control" shall be used for performing various types of field work.
The mode "FDA automatic control" is disengaged by setting switch 3 into the posi-
tion "FDA off". In this case annunciator 2 goes out.
If FDAD positive activation is required irrespective of rear wheel skidding, set switch 3 into
the position "FDA positive activation". In this case the FDA drive is permanently engaged
and annunciator 2 is on. To disengage the positive activation mode, set switch 3 into the
position "FDA off", and annunciator 2 goes out.
