Introduction
This quick reference guide has been produced to aid operators with familiarisation and
settings for the CLAAS AVERO combines.
CLAAS combines are designed for output and efficiency but this can only be achieved
with correct operation and maintenance of the machine.
This guide is not designed to replace the Operators Manual but merely as a reference
document. More in depth information is available in the Operators Manual.
ALWAYS READ THE OPERATORS MANUAL BEFORE OPERATING YOUR COMBINE
.
Down time costs output
To get the most from the machine, the wheels must be turning. In order to keep
downtime to a minimum, it’s vital that routine maintenance is not neglected. As well as
servicing the machine according to the operator’s manual, a good check of the
machine is essential. It is false economy to put off the replacement of worn parts until
they break. For example, a cracked knife section will take 5 minutes to change before
starting work, but usually a minimum of 10 minutes output will be lost, once work has
begun.
Abbreviations
Throughout this guide the following abbreviations are used:
‘LHS’ and ‘RHS’ refer to the Left Hand Side and Right Hand Side of the machine
respectively, taken from the rear of the machine facing in the direction of travel
APS –Accelerated Pre-Separation, refers to the accelerator drum in front of the main
drum
ISS –Refers to the Intensive Separation System over the straw walkers.

Safety
Safety is of the utmost importance whilst you are operating and maintaining your
combine harvester. Make sure that all of the risks are assessed to reduce the likelihood
of an accident.
Make sure you are familiar with the controls and operation of the machine and have
read the operators manual
The combine harvester has many moving parts, guards are designed to keep you
safe, please ensure that all guards are kept in place and in good condition when
operating the machine.
When doing any maintenance work or making adjustments outside of the machine
make sure that the engine is switched off and the battery isolator key is removed.
If you need to go underneath the front elevator/ cutterbar to make adjustments/
clean concaves, preparation pan, etc. Make sure that the cutterbar lift cylinder lock is
in place.
Some of the maintenance has to be carried out at height, please asses the risks that
this poses and ensure that the task is carried out safely.
When operating the machine be aware of the presence of people particularly in
farmyards, always get someone to help you when reversing in confined areas.
Be aware of the size of your machine, particularly the height, you may be at risk from
contact with overhead power lines and overhead obstructions particularly but not
exclusively when the graintank lids are up and if extra aerials have been fitted to your
machine.
For more in depth safety information please consult your operators manual. Other
information is available on the HSE website: www.hse.gov.uk
Always read the Operators Manual before using any new machine.

AUTO CONTOUR
Cutting height
The cutting height is displayed above the bar (A) between the
numbers 100 and 55. (Numbers are only for illustration use
and are not on the Combine)
100 = Cutterbar skids do not touch the ground and the
sensing bars are fully swung out.
55 = Cutterbar skids have slight contact with the ground so
the sensing bars are fully swung in.
(A) Is the ATUO CONTOUR sensitivity which is set at 45% but is
fully adjustable. 100% = maximum sensitivity, 0% =
no response from sensing bars.
Ground pressure
The ground pressure is displayed with the black bars below
(A), in this example between numbers 55 and 0.
55 = Cutterbar skids have slight contact with the ground so
the sensing bars are fully swung in.
0 = The full weight of the Cutterbar is on the ground.

10
Cutting height pre-selection
The cutting height pre-selection ensures the cutting height
stays constant with the machine, it measures the position of
the trunking and not the Cutterbar sensing bars.
The cutting height is displayed using black bars between 100
and 0. (Numbers are only for illustration and not used on the
Combine).

drum speed display.
–Actuate switch (2) and set the drum speed.
The drum speed (3) is displayed in
the onboard information system.
Fan speed adjustment
Actuate switch (1) and make the pre-selection for the
fan speed display.
–Actuate switch (4) and set the fan speed.
The fan speed (3) is displayed in the
onboard information system.
For machine field settings refer to the relevant section of the Operators Manual, this
section offers a quick guide on how to adjust the machine settings

Combine Adjustments - Cutterbar
The cutterbar is one of the most important parts of
the combine harvester. It is designed to cut and
gather the crop from the field. It then needs to feed
the material evenly and preferably head first to the
drum.
Dividers
The first part of the cutterbar to make contact with the crop are the dividers. There are
two types either the long divider or special short divider.
Make sure that the height of the long divider is set so it does not run on the ground, it
is recommended that the shoe should be set to the same height as the stubble.
Lifters
It is recommended that lifters should be fitted to
CLAAS cutterbars. The lifters should be fitted by
placing the first one on the fifth finger from the
RHS of the cutterbar and then on every fourth
one thereafter.
Lifters should be checked for wear/fatigue on a
daily basis and replaced if necessary.
There are two types of lifter available, these are
the standard lifter and the low cut lifter for
when lower cutting heights are required i.e
peas.

17
Knife
Check that the knife is in good condition in order for it to work effectively. This involves
replacing damaged or broken sections, removing vertical movement by adjusting the
keeps and making sure that the fingers are not rounded or bent. Regular
checks/adjustments will aid cleaner cutting and reduced stress on the knife drive
system.
Table auger
The table auger is important for the
transportation of material to the front
elevator.
The timing of the retractable fingers can
be adjusted for different crops by
opening up the guard on the RHS of the
cutterbar and adjusting the lever with a
spanner. Use the top holes for short
crops and the lower holes for tall crops.
The 3rd hole from bottom is the standard
setting.
1. Adjust the stripper plates behind the auger.
2. Remove the intermediate retractable fingers along the length of the auger
leaving just the middle ones.
3. Alter the height of the auger within the trough of the cutterbar. There should be
a minimum gap of 20mm between the trough and the auger flights.
4. Alter the speed of the auger by swapping the sprocket on the LHS of the
cutterbar.
Crop Wrapping Problems
If a problem with crop wrapping around the table auger in difficult conditions occurs
there are a number of procedures that can be carried out, try one thing at a time.
Combine Adjustments - Cutterbar

18
During normal use ensure the couplings for the side
knife are connected together inside the RHS guard to
avoid damage to the hydraulic pump.
When the filler plates are being used, ensure that the
knife is retracted against the filler plates on a daily
basis and make sure the power switch for the
cutterbar is SWITCHED OFF.
Skids
The skids underneath the cutterbar should be
set to suit the local conditions i.e stones, loose
soil, etc. It is recommended that they are lifted
right up in abrasive conditions.
VARIO (if fitted)
VARIO cutterbars allow the operator to vary the position of the knife to suit different
crop conditions. In short crops the knife can be retracted by up to 10cm and extended
by 20cm from its ‘normal’ position for taller crops. For extremely tall crops such as
Oilseed Rape the knife can be extended by 50cm from it’s normal position, in
conjunction with the fitment of filler plates.
Check the hydraulic oil in the oil
tank on the back of the cutterbar
daily.
When using the cutterbar in normal
conditions the knife positions can
be saved as part of the pre-set
working positions.
Combine Adjustments - Cutterbar

19
Drum speed can be adjusted by
using the drum selector switch and
the drum speed switch, it is
recommended that the drum
speed is adjusted by 50rpm at a
time.
To obtain initial settings it is recommended that the suggested settings within the
Operators Manual are used, these are to only be used as a starting point, then
adjustments should be made from there. Often changing one thing can change another.
Only make one adjustment at a time.
Only do ‘Just Enough’ to avoid overloading the machine and using power unnecessarily.
Threshing
Prime consideration here is to remove the
maximum amount of seed with the minimum of
damage to seed and straw. Over-threshing cracks
grains, produces more chaff and takes more
power.
The concave can be adjusted by using the lever
situated at the RHS of the drivers seat. By lifting
the lever the drum to concave gap is reduced and
by lowering the lever it is increased. It is
recommended that the lever is only moved by one
notch at a time and not when threshing.
