procedure will have to be followed.
Contact your local dealer to carry out this job.
IMPORTANT: Brake fluid has a tendency to absorb
moisture and brake down over time. Therefore it
should be replaced every two years. As brake fluid
contains substances which, when mixed with engine
or other oils,create problems for recycling the oil, do
not mix oil, but collect separately.

The straw elevator chain is factory fitted so there is
a minimal distance between the header auger and the
straw elevator chain to obtain a proper feeding.
IMPORTANT: It is required to check the straw
elevator chain tension within the first 50 hours to
prevent chain damage.
The tension of the straw elevator chain is kept
constant by springs 1 on both sides of the straw
elevator which pulls mounting supports 4 of the lower
shaft forward.
126
The chain tension is correct:
spring length 1 = indicator plate length 2.
Adjust with nuts 3.
As the chain stretches, the supports will gradually
move towards the end of the slots.
In this case, remove an offset link of the three chains
and readjust the chain tension.
Proceed as follows:
1. Turn the straw elevator chain until the connecting
links of the chains are at the front opening.
2. Loosen nuts 3 (fig. 126) on both sides of the straw
elevator to slacken the straw elevator chain.

GRAIN STORAGE
Slip clutch
The clean grain drive line is protected by an audible
slip clutch.
This slip clutch is factory-set and does not need any
adjustment.
175
Moisture sensor (if installed)
The moisture sensor measures grain that is falling out
of the clean grain elevator into a small bin of the
bypass unit. The moisture content of the grain in this
bin is sensed by the moisture sensor at the back of
the bypass unit. The level of grain in the bin is
controlled by a proximity switch, which is located at
the top of the bin and an auger at the bottom of the
bin. In order to have a good moisture reading the
moisture sensor fin must always be clean and
covered totally by grain.
In other words the bin has to contain always a
minimum amount of grain.
176
4-72
SECTION 4 - LUBRICATION AND MAINTENANCE
• The moisture sensor fin must be clean.
A sensor fin covered with dirt and crop residue will
result in wrong moisture readings.
Therefore it is advised to clean the sensor fin when
necessary. The frequency of the cleaning is
dependent on the harvesting conditions.
Certainly in case of dirty, and conditions where other
parts of the combine tend to build up dirt (grain pan,
sieves, bubble-up auger) it is advised to check the
sensor fin daily and clean it if necessary.
To clean the sensor fin proceed as follows:
1. Loosen two wing nuts 1 to remove sensor fin 2.
177
2. Clean the fin, using a clod.
CAUTION
Do not use a screwdriver or any other sharp device
to avoid scratches on the sensor fin to clean.
3. Install the sensor fin and tighten the wing
nuts.(fig. 177)
4. To calibrate the moisture sensor, refer to
“SECTION 2 - CONTROLS, INSTRUMENTS
AND OPERATION”.
178
4-73
SECTION 4 - LUBRICATION AND MAINTENANCE
• The level sensor must be clean.
(proximity switch)
NOTE: It should be remarked that due material
blockage (pieces of maize cobs) in front of the level
sensor will also cause the auger to turn continuously
when the threshing is on. This situation can be
recognized when the moisture readings are
abnormally low or largely fluctuating. Therefore
remove the moisture sensor. Then you can look into
the bin. In the top of the bin a white circle (=level
sensor head surface) must be visible without being
covered by dirt or crop residues. If you found material
accumulated in front of the level sensor, remove it.
To check if the level sensor (proximity switch) is
clean, proceed as follows:
1. Pull two pins 3 out to remove the auger.
179
2. Remove the auger.
180
4-74
SECTION 4 - LUBRICATION AND MAINTENANCE
3. Loosen two wing nuts 1 to remove sensor fin 2.
181
4. Remove all the grain out of auger chamber 4.
NOTE: No grain may be in front of the level sensor.
5. If there is still grain or dirt in front of the level
sensor, remove it.
182
6. Install the auger and install the two pins.
7. Install the sensor fin and tighten the wing nuts.
NOTE: If the moisture reading is still fluctuating or the
electrical motor keeps on turning all the time when
threshing is on then contact your local dealer.

SECTION 4 - LUBRICATION AND MAINTENANCE
Grain flow sensor (if installed)
There are two important points to have a good
functionality of the grain flow sensor:
• The sensor plate must be clean
In some harvesting conditions it can happen that
material starts building up on the sensor plate. These
conditions can be recognised when other combine
elements (sieves, bubble-up auger, grain pan) start to
accumulate dirt. In case of serious material built up,
the readings of the sensor will become wrong.
Therefore it is advised to check daily. Clean sensor
plate 1 whenever other combine elements in the
183
combine needs to be cleaned for proper functioning.
To clean, proceed as follows:
1. Open the grain tank covers (if installed)
2. Remove the cover 1.
184
3. Open fast coupler 2 on top of the grain elevator
and swing the sensor open to the front of the
combine.
185
4-76
SECTION 4 - LUBRICATION AND MAINTENANCE
4. Sensor plate 1 is now visible and can be cleaned
if necessary.
CAUTION
Do not use a screwdriver or any other sharp device
to avoid scratches on the sensor plate.
5. Close the sensor and secure with the fast coupler.
6. Reinstall the cover.
To calibrate the grain flow sensor, refer to
“SECTION 2 - “CONTROLS, INSTRUMENTS AND
OPERATION”.
186
To adjust the sensor plate 1 (fig. 186), proceed as
follows:
1. The sensor plate 1 is adjusted correctly, if it is
possible to insert a rod into hole 3.
2. If not, adjust the plate by adjusting the two
supports 4 in combination with the fast coupler 2.
