21. Instructions for working with crossflow fans
•
The distance of the crossflow fan must be set so that no branch-
es / foliage can penetrate the protective grids and thus block the
crossflow fans.
•
Prior to starting, check that the inner area of the crossflow fan is
free of contamination.
Note:
Maximum allowable hydraulic pressure for the crossflow fan is
120 bar. Higher pressure can result in hydraulic motor damage
of the fan drive.
•
Following data to be supplied by the tractor at idling speed must
be checked before starting crossflow fan.

•
In addition, the functional condition of the oil filter in the oil circuit
of the crossflow fan must be checked.
•
When starting up the crossflow fans, make sure that they run
evenly in idle operation of the tractor, especially that they vibrate
excessively due to unbalance or other noises.
•
Avoid switching on the crossflow fan at full tractor rpm, as the
crossflow fan can warp strongly as a result of the sudden start
and there is a risk of damage.
•
Check that the crossflow fans are running correctly by slowly in-
creasing the rpm.
•
The hydraulic connections of the crossflow fans must be con-
nected accordingly, as otherwise the hydraulic oil motors can be
damaged.
