8. Repair, maintenance and
servicing
8.1 Computer
AMATRON II-A is maintenance free. It is provided
with an electronic safety device. During winter time
AMATRON II-A should be stored at room tem-
perature. To guard against dust and moisture –all
outlets not in use must be protected with caps. in
8.2 Fertiliser spreader
I
When you intend to clean your fertil-
iser spreader with a high pressure
cleaner take care that the cleaning jet
is not directed towards the cable
outlets, sensors and sockets.
After cleaning apply oil to the joints on the levers.
I
Before carrying out welding work on
the tractor or spreader disconnect the
electronic power supply for AMTRON
II-A.
8.2.1 Check shutter slide main setting
and the impulses of the setting
motors
I
The setting motors have been set by
the manufacturer in such a way that
the rate setting slide at closed hy-
draulic shutter slides return after
switching on AMATRON II-A nearly to
the 0-position on the scale.
F
A change of the setting lever basic
setting is only necessary if
• the setting motor had been ex-
changed.
• the desired and the actual spread
rate considerably deviate and a
calibration fault or other faults can
be excluded.
• an uneven emptying of the two
hopper tips is noted.
Prior to operation
- Mount the fertiliser spreader to the tractor and
connect AMATRON II-A with the power supply.
Do not fill the hopper with fertiliser.
- Switch on AMATRON II-A.
- Select data block "job".
- Enter the required spread rate of 518 kg/ha
via the ten digit key board and store.
- Enter the working width of 20 m and store.
- Enter the value 1.15 for the fertiliser calibra-
tion factor and store.
Execution
1. Check shutter slide position in the basic set-
ting
- Open shutter slide.
- Speed up your tractor up to 8 km/h until the
AMATRON II-A shows the following display:
Fig. 100
- While the display shows 8.0 km/h and 518
kg/ha switch off AMATRON II-A.
- Stop the tractor and read the shutter slide posi-
tion for the metering shutter slides off the scale
for the spread rate setting.
- The read-off edge of the pointer must indicate
for both metering shutter slides the shutter slide
position 41±1.
F
The shutter slide position 41±1 is only
a mean value. Decisive is the opened
diameter of the outlet opening.
The opening allowed by the metering
shutter slide must be 62 mm.
