8.4 Adjusting blower fan speed
This adjustment is not required if the blower fan is driven by the trac-
tor universal joint shaft.
Set the target blower fan speed (Fig. 71)
• via the tractor's flow control valve
• at the pressure relief valve of the blower fan hydraulic motor if
the tractor does not have any flow control valve.
In the AMATRON 3, set:
• the target blower fan speed
• the deviation from the target blower fan speed (as a percent-
age) at which the alarm should be triggered.
