Connecting the hydraulics
CAUTION
Damage on the fan motor -
gear motor
¾
Be sure to connect the return line to the pres-
sureless return of the tractor!
¾
Note the return flow pressure of max. 5 bar
in the leak oil line!
Gear motor connection
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
in the leak oil line!
Axial piston motor connection
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
The fan impeller 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.
WARNING
Risk of injury from running fan.
¾
Remove the protective grille only after the fan
has stopped.
To control the speed, the control unit in the trac-
tor must be equipped with a flow control valve.
Rotary speeds
Gear motor
max. 4,000 rpm
Axial piston motor
max. 5,000 rpm
Speed
max. 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.
