Checks and maintenance
WARNING
Risk of injury from running fan
¾
Deactivate the fan drive before beginning
with maintenance work and secure it against
restarting.
NOTE
The fan speed setting for fertiliser placement
must be checked on all coulters before starting
work and also at regular intervals when working
on large areas.
¾
Leak oil: Ensure a free flow return pressure
of max. 5 bar.
¾
Check the oil level.
¾
Retighten the clamping taper on the fan shaft
(see chapter Retightening the fan flange ).
Deposits on the protective grid restrict the air
flow and thus lead to blockage in the hoses.
¾
Clean the protective suction grid at regular
intervals to prevent a restriction in air flow and
resulting blockage.
Deposits on the fan impeller cause unbalance.
The bearing will thereby be overloaded and can
be damaged.
¾
Clean any dirt or deposits from the fan blades
to prevent unbalance and damage to impeller
and bearing.
The hydraulic oil could overheat if the radiator
fins are soiled and cause clogging of the fertiliser
hoses.
¾
Clean the radiator fins at regular intervals.
Retightening the fan flange
The clamping taper fixates the fan wheel and
additionally clamps on the drive shaft.
The clamping taper on the fan drive may come
loose. The impeller can thus move along the
drive shaft and damage the fan.
¾
After approx. 50 hours retighten the clamping
taper on the fan flange and check it annually.
Clamping taper
Please note
¾
When tightening the screws, especially with
a new assembly, the fan wheel will move
towards the housing in the direction of the
protective grid.
¾
A loose flange must therefore be aligned
closer to the hydraulic motor.
¾
The clamping faces must be free of oil and
grease.
¾
The clamping screws must be tightened
uniformly and in several steps. Tightening
onto the taper should be supported by light
hammer blows on the flange (plastic hammer
or hammer shaft).
¾
The inch screws in design No. 10 - 24 4.6
must only be tightened with a torque of
max. 6.8 Nm.
¾
After tightening check the impeller for free and
even running.
¾
Check the fan impeller and the protective grid
regularly for dirt deposits and clean.
