NOTE
¾
Fan setting, seed transport and seed place-
ment must be checked on all coulters when
starting sowing and also at regular intervals
when working on large areas.
NOTE
¾
Fan wing and protective grid must be regularly
checked for dirt deposits and cleaned.
Deposits on the protective grid restrict the air
flow and thus lead to blockage in the seed
pipes.
Deposits on the fan impeller cause unbalance.
The bearing will thereby be overloaded and
can be damaged.
To control the speed, the control unit in the trac-
tor must be equipped with a flow control valve.
Max. speed 4,500 rpm.
Fan motor direct drive
The fan speed is adjusted via the oil quantity on
the flow control valve in the tractor.
The hydraulic pump must deliver sufficient oil
to prevent the fan speed from dropping, even
when the tractor speed drops or other hydraulic
functions are activated.
Connecting the hydraulics
CAUTION
Damage on the fan motor -
axial piston motor
¾
Connect the leak oil line to the leak oil port
of the tractor!
¾
Note the return flow pressure of max. 2 bar
of the leak oil line!
Axial piston motor connection
Checks and maintenance
¾
Maintenance work on the fan and opening of
the protective grille only while the machine is
at a standstill. Let the fan only run while the
protective grille is mounted:
Fan with protective grille
¾
Clean the protective grille at regular intervals
to prevent a restriction in air flow and resulting
blockage.
¾
Clean any dirt or deposits from the fan blades
to prevent unbalance and damage to impeller
and bearing.
¾
Retighten the clamping taper on the fan shaft
(see chapter
Retightening the fan flange
).
